In this case, the controller 170 does not filter the Rx data received from the first other vehicle 101 and the second other vehicle 102. The controller 170 makes various determinations and performs various control operations using the Rx data received from the first other vehicle 101 and the second other vehicle 102.


Upon receipt of Rx data from the third other vehicle 103 and the fourth other vehicle 104 through the communication device 400, the controller 170 may determine transmission positions of the Rx data are outside the reception zone.


In this case, the controller 170 filters the Rx data received from the third other vehicle 103 and the fourth other vehicle 104. The controller 170 does not use the Rx data received from the third other vehicle 103 and the fourth other vehicle 104 in making determinations or performing control operations.



FIGS. 10 to 15 are views illustrating operations for configuring a reception zone according to an ambient situation of a vehicle according to an embodiment of the present disclosure.


Vehicle driving information includes ambient situation information related to an ambient situation of the vehicle 100.


The controller 170 may determine a Region Of Interest (ROI) for the vehicle 100 based on the ambient situation information.


The controller 170 may set the ROI as a reception zone.


Referring to FIG. 10, if the controller 170 determines that the vehicle 100 is driving on a 2-way road based on ambient situation information, the controller 170 may determine an area except for Opposite Lanes (OL) to the vehicle 100 on the 2-way road to be an ROI.


The 2-way road is a road including one or more Driving Lanes (DLs) directed in a driving direction of the vehicle 100 and one or more OLs directed in a direction opposite to the driving direction of the vehicle 100.


A DL refers to a lane running in the driving direction of the vehicle 100.


An OL refers to a lane running in the direction opposite to the driving direction of the vehicle 100.


The controller 170 may determine whether a road on which the vehicle 100 is driving is a 2-way road based on ambient situation information.


For example, the controller 170 may determine whether a road on which the vehicle 100 is traveling is a 2-way road based on at least one of map information received from the navigation system 770 or object information received from the object detection device 300.


If the road on which the vehicle 100 is driving is a 2-way road, the controller 170 may divide the entire area of the 2-way road into a zone with the DLs and a zone with the OLs based on the ambient situation information.


The controller 170 may determine the zone with the DLs in the entire area of the 2-way road to be an ROI.


The controller 170 may determine the ROI to be a reception zone. Accordingly, the controller 170 may determine the zone with the DLs to be the reception zone.


In the embodiment of FIG. 10, the second other vehicle 102 and the third other vehicle 103 are driving on the DLs, whereas the first other vehicle 101 and the fourth other vehicle 104 are driving on the OLs.


The controller 170 may receive data from each of the first to fourth other vehicles 101 to 104 through the communication device 400. In this case, data transmitted by the first other vehicle 101 is referred to as first Rx data, data transmitted by the second other vehicle 102 is referred to as second Rx data, data transmitted by the third other vehicle 103 is referred to as third Rx data, and data transmitted by the fourth other vehicle 104 is referred to as fourth Rx data.


The controller 170 may determine transmission positions of the first to fourth Rx data.


The controller 170 may determine the transmission positions of the first Rx data and the fourth Rx data to be in the zone with the OLs.


The controller 170 may determine the transmission positions of the second Rx data and the third Rx data to be in the zone with the DLs.


Accordingly, the controller 170 may determine the transmission positions of the first Rx data and the fourth Rx data to be outside the reception zone, and the transmission positions of the second Rx data and the third Rx data to be inside the reception zone.


Since the transmission positions of the first Rx data and the fourth Rx data are outside the reception zone, the controller 170 may filter the first Rx data and the fourth Rx data.


Since the transmission positions of the second Rx data and the third Rx data are inside the reception zone, the controller 170 may perform various computations and make various determinations, using the second Rx data and the third Rx data.


Accordingly, the controller 170 may make various determinations regarding the ROI by receiving data only from the DLs. As the controller 170 filters data received from the OLs, the controller 170 filters the unnecessary data, thereby reducing communication congestion.


Referring to FIG. 11, if the controller 170 determines that the vehicle 100 will pass through an intersection based on ambient situation information, the controller 170 may determine an area within a predetermined distance from the intersection to be an ROI.


The controller 170 may determine whether the vehicle 100 will pass through an intersection based on ambient situation information.


For example, if the controller 170 determines based on a Set Path (SP) for the vehicle 100, generated by the navigation system, that there is an intersection in the path, the controller 170 may determine that the vehicle 100 will pass through the intersection.


For example, if the controller 170 determines based on object information received from the object detection device that there is an intersection ahead of the vehicle 100, the controller 170 may determine that the vehicle 100 will pass through the intersection.


If the controller 170 determines that the vehicle 100 will pass through the intersection, the controller 170 may determine an area within a predetermined distance from the intersection to be an ROI.


The controller 170 may determine the ROI to be a reception zone. Accordingly, the controller 170 may determine the area within the predetermined distance from the intersection to be the reception zone.


Upon receipt of data from the first, second and third other vehicles 101, 102 and 103, the controller 170 may determine that transmission positions of the Rx data to be inside the reception zone.


A kind of infrastructure, a signal lamp or surveillance camera may broadcast data in a predetermined range.


The controller 170 may receive data from the signal lamp or the surveillance camera. The controller 170 may determine whether the signal lamp or the surveillance camera is located in the reception zone based on the data received from the signal lamp or the surveillance camera. If the controller 170 determines that the signal lamp or the surveillance camera is located in the reception zone, the controller 170 may determine that a transmission position of the Rx data is inside the reception zone.


The controller 170 may use Rx data which is determined to have been transmitted from the reception zone, in various computations and control operations.


Upon receipt of data from fourth, fifth and sixth other vehicles 104, 105 and 106, the controller 170 may determine that transmission positions of the Rx data are outside the reception zone.


In this case, the controller 170 may filter the data received from the fourth, fifth and sixth other vehicles 104, 105 and 106.


Therefore, the controller 170 may make various determinations regarding the ROI by receiving data only from the area within the predetermined distance from the intersection. As the controller 170 filters data received from the outside of the ROI, the controller 170 filters the unnecessary data, thereby reducing communication congestion.


Referring to FIG. 12, if the controller 170 determines that the vehicle 100 will pass through an area in which an accident has occurred based on ambient situation information, the controller 170 may determine the area in which the accident has occurred (hereinafter, referred to as an ‘accident area’) to be an ROI.


An accident area refers to an area within a predetermined distance from a point at which an accident has occurred.


Accident vehicles 101 and 102 may broadcast accident information to indicate occurrence of the accident and the position of the accident to their neighborhood.


A server or infrastructure installed on a road may transmit traffic information indicating an accident which has occurred on the road, information about the accident, and the position of the accident to vehicles driving on the road.


Traffic information and accident information are included in ambient situation information.


The controller 170 may determine the point at which the accident has occurred based on the traffic information or accident information.


Once the controller 170 determines the point at which the accident has occurred, the controller 170 may determine the accident area to be an ROI.


The controller 170 may determine the ROI to be a reception zone. Accordingly, the controller 170 may determine the accident area to be the reception zone.


The controller 170 may determine whether Rx data has been transmitted from the accident area by determining a transmission position of the Rx data.


In the embodiment of FIG. 12, the controller 170 may determine that data received from the accident vehicles 101 and 102, the fourth other vehicle 104, and the fifth other vehicle 105 have been transmitted from the ROI, that is, the accident area.


The controller 170 may determine that data received from the third other vehicle 103 has been transmitted from the outside of the ROI.


The controller 170 may filter the data received from the third other vehicle 103.


Therefore, the controller 170 may make various determinations regarding the accident area by receiving data only from the accident area. As the controller 170 filters data received from the outside of the accident area, the controller 170 filters the unnecessary data, thereby reducing communication congestion.


Referring to FIGS. 13A, 13B, the controller 170 may determine the traffic congestion degree of a road on which the vehicle 100 is driving based on ambient situation information, and set a reception zone such that the size of the reception zone is inversely proportional to the traffic congestion degree.


A server or infrastructure installed on a road provides information about a traffic congestion degree representing a traffic load by section. Information about the traffic congestion degree is included in traffic information.


The controller 170 may determine the traffic congestion degree of a section on which the vehicle 100 is driving based on the traffic information. For example, the traffic information may be Transport Protocol Expert group (TPEG) information.


The controller 170 may determine the traffic congestion degree of the section on which the vehicle 100 is driving based on the locations and number of other vehicles detected through the object detection device 300. Since a traffic congestion degree may correspond to the density of vehicles in a specific area, the controller 170 may determine the traffic congestion degree of the surroundings of the vehicle 100 based on the density of vehicles determined based on the locations and number of other vehicles around the vehicle 100.


The controller 170 may set a reception zone such that the size of the reception zone is inversely proportional to the traffic congestion degree.


Accordingly, as the traffic congestion degree increases, the controller 170 may decrease the size of the reception zone, and as the traffic congestion degree decreases, the controller 170 may increase the size of the reception zone.


Reception zone sizes mapped to traffic congestion degrees may be stored in a preset look-up table. The look-up table is stored in the memory 140.



FIG. 13A illustrates a less congested traffic situation than FIG. 13B, which illustrates a more congested traffic situation than FIG. 13A.


The controller 170 may set a relatively large reception zone in the situation of FIG. 13A. The controller 170 may set a relatively small reception zone in the situation of FIG. 13B. Therefore, the reception zone in the situation of FIG. 13A is larger than the reception zone in the situation of FIG. 13B.


Because as the traffic congestion degree is higher, other vehicles are populated more densely around the vehicle 100, the vehicle 100 receives more data, resulting in increased communication congestion. According to the present disclosure, the vehicle 100 decreases the size of a reception zone for an increased traffic congestion degree, thereby reducing the communication congestion.


Referring to FIGS. 14 and 15, the controller 170 may determine an area corresponding to an SP of the vehicle 100 to be an ROI, based on ambient situation information and navigation information.


Vehicle driving information may further include navigation information provided by the navigation system 770 of the vehicle 100.


The SP of the vehicle 100 may be a path in which the vehicle 100 will reach a pre-input destination.


The navigation system 770 may generate the SP of the vehicle 100 based on location information about the vehicle 100, map information, traffic information, and an input destination.


The navigation system 770 may provide information about the SP to the controller 170.


An area corresponding to the SP of the vehicle 100 may be an area within a predetermined distance from the SP of the vehicle 100.


In the embodiment of FIG. 14, the controller 170 may determine a road corresponding to an SP of the vehicle 100 between two branched roads based on ambient situation information and navigation information.


The controller 170 may determine the road corresponding to the SP of the vehicle 100 between the two branched roads to be an ROI.


The controller 170 may determine a road on which the vehicle 100 drives along the SP from a current location to be the ROI.


The controller 170 may determine the ROI to be a reception zone.


The controller 170 may determine that data received from the first other vehicle 101 driving in the SP has been transmitted from the reception zone. The controller 170 may make various determinations regarding the SP, using the data received from the first other vehicle 101.


The controller 170 may determine that data received from the second other vehicle 101 driving in a path other than the SP has been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the second other vehicle 102.


As the controller 170 filters the data received from the second other vehicle 102 that has no relation to the SP, the controller 170 may reduce communication congestion.


In the embodiment of FIG. 15, the controller 170 may determine an area corresponding to an SP of the vehicle 100 on a multi-lane road including a plurality of lane, based on ambient situation information and navigation information.


The controller 170 may determine the area corresponding to the SP of the vehicle 100 on the multi-lane road to be an ROI.


The controller 170 may determine the ROI to be a reception zone.


The controller 170 may determine that data received from the third other vehicle 103 and the fourth other vehicle 104 have been transmitted from the reception zone.


The controller 170 may make various determinations regarding the area corresponding the SP of the vehicle 100, using the data received from the third other vehicle 103 and the fourth other vehicle 104.


The controller 170 may determine that data received from the first other vehicle 101 and the second other vehicle 102 located outside the ROI have been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the first other vehicle 101 and the second other vehicle 102.


As the controller 170 filters the data received from the first other vehicle 101 and the second other vehicle 102 which are not related to the SP, the controller 170 may reduce communication congestion.



FIGS. 16A, 16B, 17A, 17B, and 18A, 18B, are views illustrating operations for configuring a reception zone according to a vehicle state in a vehicle according to an embodiment of the present disclosure.


Vehicle driving information includes vehicle state information representing operation states of various devices of the vehicle 100.


The controller 170 may configure a reception zone based on the vehicle state information.


The controller 170 may determine an ROI for the vehicle 100 based on the vehicle state information. The controller 170 may set the ROI as a reception zone.


Referring to FIGS. 16A, 16B, the controller 170 may determine a speed of the vehicle 100 based on vehicle state information, and configure a reception zone such that the size of the reception zone is proportional to the speed of the vehicle 100.


The vehicle state information may include information about the speed of the vehicle 100.


The controller 170 may determine a current speed of the vehicle 100 based on the vehicle state information.


The controller 170 may determine the size of the reception zone so that the size of the reception zone may be proportional to the speed of the vehicle 100.


As the speed of the vehicle 100 increases, the controller 170 may increase the size of the reception zone.


As the speed of the vehicle 100 decreases, the controller 170 may decrease the size of the reception zone.


Reception zone sizes mapped to speeds of the vehicle 100 may be stored in a preset look-up table. The look-up table is stored in the memory 140.


In FIG. 16A, it is assumed that the speed of the vehicle 100 is 30 km/h.


The controller 170 may determine the size of a reception zone based on the speed of the vehicle 100.


The controller 170 may configure a reception zone according to the determined reception zone size.


The controller 170 may determine that data received from the second other vehicle 102 has been transmitted from the reception zone.


The controller 170 may determine that data received from the first other vehicle 101 and the third other vehicle 103 have been transmitted from the outside of the reception zone.


The controller 170 filters the data received from the first other vehicle 101 and the third other vehicle 103.


If the vehicle 100 is relatively slow, the vehicle 100 does not need to receive data from a remote place. Accordingly, the vehicle 100 of the present disclosure may adjust the size of a reception zone according to the speed of the vehicle. Thus, the vehicle 100 filters data with low importance, thereby reducing communication congestion.


In FIG. 16B, it is assumed that the speed of the vehicle 100 is 80 km/h.


In this case, the controller 170 may configure a larger reception zone than when the speed of the vehicle 100 is 30 km/h.


The controller 170 may determine that data received from the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103 have been transmitted from the reception zone.


The controller 170 may make various determinations, using the data received from the first other vehicle 101, the second other vehicle 102, and the third other vehicle 103.


If the vehicle 100 is relatively fast, the vehicle 100 needs to receive data from a remote place. Accordingly, when the vehicle 100 drives fast, the vehicle 100 may increase the size of the reception zone, thereby avoiding filtering of necessary data in the present disclosure.


Referring to FIGS. 17A, 17B, the controller 170 may determine the direction and size of a steering angle based on vehicle state information, and configure a reception zone in correspondence with the direction and size of the steering angle.


The vehicle state information includes information about steering of the vehicle, received through the steering input device 510.


The steering angle may be a steering angle of a front wheel of the vehicle 100.


The direction of the steering angle may be the left or right direction with respect to the front of the vehicle 100.


The size of the steering angle is the absolute value of the size of the steering angle.


The controller 170 may determine the direction and size of the steering angle based on the information about steering of the vehicle 100.


In the embodiment of FIG. 17A, the controller 170 may determine that the direction of a steering angle is left and the size of the steering angle is a first angle SA1.


In the embodiment of FIG. 17B, the controller 170 may determine that the direction of a steering angle is right and the size of the steering angle is a second angle SA2.


The controller 170 may configure a reception zone in correspondence with the direction and size of a steering angle.


The controller 170 may configure the reception zone to be inclined according to the direction of the steering angle.


If the controller 170 configures the reception zone to be inclined, the controller 170 may configure the reception zone so that the inclination of the reception zone is proportional to the size of the steering angle.


In the embodiment of FIG. 17A, the controller 170 may configure a reception zone to be inclined to the left at the first angle SA1 in correspondence with the direction and size of the steering angle.


The controller 170 may determine that data received from the first other vehicle 101 has been transmitted from the reception zone.


The controller 170 may determine that data received from the second other vehicle 102 and the third other vehicle 103 have been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the second other vehicle 102 and the third other vehicle 103.


In the embodiment of FIG. 17B, the controller 170 may configure a reception zone to be inclined to the right at the second angle SA2 in correspondence with the direction and size of the steering angle.


The controller 170 may determine that data received from the second other vehicle 102 has been transmitted from the reception zone.


The controller 170 may determine that data received from the first other vehicle 101 and the third other vehicle 103 have been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the first other vehicle 101 and the third other vehicle 103.


Referring to FIGS. 18A, 18B, the controller 170 may determine operations of turn signal lamps based on vehicle state information, and configure a lane corresponding to the direction of a turn signal lamp and a driving lane of the vehicle 100 as a reception zone.


The vehicle state information may include information about an operation of a turn signal lamp provided in the vehicle 100.


The controller 170 may determine whether a turn signal lamp has been turned on, and the direction corresponding to the turned-on turn signal lamp, based on the information about the operation of the turn signal lamp.


If the controller 170 determines that a turn signal lamp has been turned on, the controller 170 may set a lane directed in the direction of the turned-on turn signal lamp and the driving lane of the vehicle 100 as an ROI.


Referring to the embodiment illustrated in FIG. 18A, if the controller 170 determines that a right turn signal lamp of the vehicle 100 has been turned on, the controller 170 may set a lane to the right of the vehicle 100 and the driving lane of the vehicle 100 as the ROI.


The controller 170 may set the ROI as a reception zone, and determine that data received from the first other vehicle 101 or the third other vehicle 103 has been transmitted from the reception zone.


Therefore, the controller 170 does not filter the data received from the first other vehicle 101 or the third other vehicle 103.


The controller 170 may determine a lane change timing of the vehicle 100, using the data received from the first other vehicle 101 or the third other vehicle 103.


The controller 170 may control the vehicle 100 based on the determined lane change timing or notify the driver of the lane change timing.


The controller 170 may determine that data received from the second other vehicle 102 has been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the second other vehicle 102. Since the data received from the second other vehicle 102 is not needed at a timing of switching to a left lane, the vehicle 100 of the present disclosure filters the unnecessary data, thereby reducing communication congestion.


Referring to the embodiment illustrated in FIG. 18B, if the controller 170 determines that a left turn signal lamp of the vehicle 100 has been turned on, the controller 170 may set a lane to the left of the vehicle 100 and the driving lane of the vehicle 100 as an ROI.


The controller 170 may set the ROI as a reception zone, and determine that data received from the first other vehicle 101 or the second other vehicle 102 has been transmitted from the reception zone.


Therefore, the controller 170 does not filter the data received from the first other vehicle 101 or the second other vehicle 102.


The controller 170 may determine a lane change timing of the vehicle 100, using the data received from the first other vehicle 101 or the second other vehicle 102.


The controller 170 may control the vehicle 100 based on the determined lane change timing or notify the driver of the lane change timing.


The controller 170 may determine that data received from the third other vehicle 103 has been transmitted from the outside of the reception zone.


The controller 170 may filter the data received from the third other vehicle 103. Since the data received from the third other vehicle 103 is not needed at a timing of switching to a right lane, the vehicle 100 of the present disclosure filters the unnecessary data, thereby reducing communication congestion.


In an embodiment different from the embodiments of FIGS. 18A, 18B, the controller 170 may set two lanes directed in the direction of a turned-on turn signal lamp and a lane in which the vehicle 100 is driving (hereinafter, referred to as a ‘driving lane’) as an ROI. The controller 170 sets the three lanes as the ROI, and sets the ROI as a reception zone. Accordingly, the three lanes become the reception zone.


In this case, the vehicle 100 does not filter data received from a lane to which the vehicle 100 is to switch (hereinafter, referred to a ‘first side lane’), a lane on a side of the first side lane (hereinafter, referred to as a ‘second side lane’), and the driving lane, and filters data received from other areas.


The controller 170 may further determine based on data received from the second side lane whether another vehicle driving in the second side lane will enter the first side lane.


If determining based on ambient situation information and vehicle state information that another vehicle driving in the second side lane and the vehicle 100 will enter the first side lane, the controller 170 may control the vehicle 100 not to enter the first side lane.


Or if determining based on ambient situation information and vehicle state information that another vehicle driving in the second side lane and the vehicle 100 will enter the first side lane, the controller 170 may transmit a message requesting holding of lane switching to the other vehicle.


In the autonomous driving mode, if determining that another vehicle driving in the second side lane will enter the first side lane, the controller 170 may delay lane switching of the vehicle 100 to prevent simultaneous entry of the other vehicle and the vehicle 100 into the first side lane.


In the manual mode, if determining that another vehicle driving in the second side lane will enter the first side lane, the controller 170 may output an alarm through the output unit 250 to prevent simultaneous entry of the other vehicle and the vehicle 100 into the first side lane.



FIGS. 19 and 20A, 20B are views illustrating an operation for configuring a reception zone according to the class of received data in a vehicle, and tables referred to for determining the class of data according to an embodiment of the present disclosure.


Referring to FIG. 19, the controller 170 may configure different reception zones according to the classes of Rx data.


Vehicle driving information includes communication information provided by the communication device 400. The communication information includes information about Rx data.


The information about the Rx data may include information about the type of the Rx data. For example, the type of the Rx data may be Basic Safety Message (BSM), sensing data, or image data.


A BSM is data about a data transmission entity. For example, the BSM may include information about the type of a data transmission entity (e.g., vehicle, infrastructure, server, mobile terminal, or the like), information about the transmission position of the data, contents to be informed (e.g., accident occurrence, a signal of a signal lamp, a traffic regulation, a traffic state, or the like), and information about a control state of a vehicle that has transmitted the data. In general, a BSM may be small in size, relative to other types of data.


Sensing data is raw data provided by various sensors of a data transmission device. For example, the sensing data may be raw data provided by an ultrasonic sensor, a LiDAR sensor, a RADAR sensor, an IR sensor, and so on of another vehicle. In general, sensing data may be larger than a BSM and smaller than image data, in size, because the sensing data is raw data before being processed.


Image data may be data provided by a camera of a data transmission device. For example, the image data may be provided by a front camera and a rear camera of another vehicle. For example, the image data may be provided by a surveillance camera installed on a road. For example, the image data may be provided by a camera of a pedestrian's mobile terminal. In general, image data may be larger in size than a BSM or sensing data.


The information about the Rx data may further include information about the size of the Rx data.


The controller 170 may determine the class of the Rx data based on the information about the Rx data.


For example, the class of the Rx data may be numerically represented. For example, the class of the Rx data may be class 1, class 2, or class 3.


According to an embodiment of the present disclosure, the controller 170 may determine the class of the Rx data based on a predetermined class table listing classes according to the types of Rx data.


For example, if the Rx data is a BSM, a preset class for the BSM may be class 3. For example, if the Rx data is sensing data, a preset class for the sensing data may be class 2. For example, if the Rx data is image data, a preset class for the image data may be class 1.


According to another embodiment of the present disclosure, the controller 170 may determine the class of the Rx data based on a preset class table listing classes according to the types and sizes of Rx data. In this case, the class of the Rx data may be inversely proportional to the size of the Rx data. The class tables will be described later in greater detail with reference to FIG. 20.


The controller 170 may configure a predetermined area for the determined class of the Rx data (hereinafter, referred to as a ‘per-class reception zone) as a reception zone.


The size of a per-class reception zone may be proportional to the class of Rx data. As the Rx data has a higher class, a reception zone corresponding to the Rx data is larger. Since as the size of a reception zone is larger, a range in which data may be used without filtering is larger, there is a higher possibility of using Rx data without filtering if the Rx data has a higher class.


In the embodiment of FIG. 19, a reception zone preset for Rx data of class 1 is a first reception zone RZ1, a reception zone preset for Rx data of class 2 is a second reception zone RZ2, and a reception zone preset for Rx data of class 3 is a third reception zone RZ3.


The embodiment of FIG. 19 is based on the assumption that each of the first to fourth other vehicles 101, 102, 103, and 104 transmits every class of Rx data.


The first reception zone RZ1 and the second reception zone RZ2 are included in the third reception zone RZ3. The first reception zone RZ1 is also included in the second reception zone RZ2.


The first reception zone RZ1 is the intersection of the first, second, and third reception zones RZ1, RZ2, and RZ3. Therefore, the first reception zone RZ1 is at once the second reception zone RZ2 and the third reception zone RZ3.


Since the first, second, and third reception zones RZ1, RZ2, and RZ3 are overlapped over the first reception zone RZ1, the controller 170 may determine the transmission position of Rx data received from the second other vehicle 102 is within the first, second, and third reception zones RZ1, RZ2, and RZ3.


The controller 170 may receive all of class-1 Rx data, class-2 Rx data, and class-3 Rx data from the second other vehicle 102. The controller 170 does not filter the class-1 Rx data, class-2 Rx data, and class-3 Rx data received from the second other vehicle 102. For example, the controller 170 uses all of a BSM, sensing data, and image data received from the second other vehicle 102 without filtering.


That is, since the first, second, and third reception zones RZ1, RZ2, and RZ3 are overlapped over the first reception zone RZ1, the controller 170 does not perform class-based filtering on Rx data received from the first reception zone RZ1.


The whole second reception zone RZ2 is included in the third reception zone RZ3. Accordingly, the whole second reception zone RZ2 is also the third reception zone RZ3. The remaining area of the second reception zone RZ2 except for the first reception zone RZ1 is at once the second reception zone RZ2 and the third reception zone RZ3.


The controller 170 may determine the transmission position of Rx data received from the first other vehicle 101 is outside the first reception zone RZ1 and inside second reception zone RZ2 and the third reception zone RZ3.


Accordingly, the controller 170 filters class-1 data among Rx data received from the first other vehicle 101, without filtering class-2 data and class-3 data among the Rx data received from the first other vehicle 101. The controller 170 makes various determinations using only the class-3 data and the class-3 data among the Rx data received from the first other vehicle 101.


The controller 170 may determine the transmission position of Rx data received from the third other vehicle 103 or the fourth other vehicle 104 is inside the third reception zone RZ3 and outside the second reception zone RZ2 and the first reception zone RZ1.


Accordingly, the controller 170 uses only class-3 data, while filtering class-1 data or class-2 data among Rx data received from the third other vehicle 103 or the fourth other vehicle 104.



FIG. 20A is a predetermined class table listing classes according to Rx data types.


For example, if the type of Rx data is BSM, a preset class for BSM may be class 3. Therefore, a reception zone for the BSM may be largest.


For example, if the type of Rx data is sensing data, a preset class for sensing data may be class 2. Therefore, a reception zone for the sensing data may be smaller than the reception zone for the BSM but larger than a reception zone for image data.


For example, if the type of Rx data is image data, a preset class for BSM may be class 1. Therefore, the reception zone for the image data may be smallest.


The preset class table listing classes according to Rx data types is stored in the memory 140.



FIG. 20B is a class table preset according to the types and sizes of Rx data.


For example, BSM may be class 3 irrespective of the size of Rx data.


For example, sensing data and image data may have different classes according to their data sizes.


Because the class of Rx data is inversely proportional to the size of the Rx data, larger sensing data and larger image data may have lower classes.


Criteria for data sizes may be empirically determined. For example, a small size may refer to 1 kb to 100 kb. For example, a medium size may refer to 101 kb to 1 mb. For example, a large size may refer to a size exceeding 1 mb.


The predetermined class table listing classes according to the types and sizes of Rx data is stored in the memory 140.


According to another embodiment of the present disclosure, the controller 170 may determine an ROI for the vehicle 100 based on ambient situation information. Once the controller 170 determines that the transmission position of Rx data is within the ROI, the controller 170 may not perform class-based filtering on the Rx data. In this case, the controller 170 determines the ROI in any of the methods described before with reference to FIGS. 10 to 18.


If determining that the transmission of Rx data is within the ROI, the controller 170 may use the Rx data in various computations or determinations without filtering the Rx data irrespective of the class of the Rx data.


For example, the controller 170 may determine an accident area as an ROI. If determining that the transmission position of Rx data is within the accident area, the controller 170 may make various determination using the Rx data, even though determining that the class of the Rx data is class 1 and the transmission position of the Rx data is outside of a reception zone for class 1.



FIG. 21 is a view illustrating an operation for configuring a transmission zone according to the class of Tx data according to an embodiment of the present disclosure.


If the controller 170 transmits data through the communication device 400, the controller 170 may configure a Tx zone based on information. The information may be vehicle driving information.


The transmission zone is an area corresponding to a range in which data is transmitted from the communication device 400. The transmission zone is an area within a predetermined distance from the vehicle 100.


The controller 170 adjusts the transmission power of the communication device 400 based on the configured transmission zone. The controller 170 adjusts the transmission power of the communication device 400 so that Tx data may be transmitted to the configured transmission zone.


The controller 170 may adjust the size of the transmission zone by adjusting the transmission power of the communication device 400.


If the transmission power of the communication device 400 increases, the size of the transmission zone also increases. The controller 170 may increase the size of the transmission zone by increasing the transmission power of the communication device 400.


If the transmission power of the communication device 400 decreases, the size of the transmission zone also decreases. The controller 170 may decrease the size of the transmission zone by decreasing the transmission power of the communication device 400.


The vehicle driving information includes information about data transmitted through the communication device 400 (hereinafter, referred to as ‘Tx data’).


The information about the Tx data may include information about the type of the Tx data.


The information about the Tx data may further include information about the size of the Tx data.


The controller 170 may determine the class of the Tx data based on the information about the Tx data.


For example, the controller 170 may determine the class of the Tx data, referring to a predetermined class table listing classes according to the types of Tx data. The predetermined class table listing classes according to the types of Tx data is identical to the predetermined class table listing classes according to the types of Rx data, illustrated in FIG. 20A.


For example, the controller 170 may determine the class of the Tx data, referring to a predetermined class table listing according to the types and sizes of Tx data. The predetermined class table listing according to the types and sizes of Tx data is identical to the predetermined class table listing according to the types and sizes of Rx data, illustrated in FIG. 20B.


The controller 170 may configure a predetermined area for the determined class of the Tx data (hereinafter, referred to as a ‘per-class transmission zone’) as a transmission zone.


The size of the per-class transmission zone is proportional to the class of the Tx data.


Thus, as the Tx data has a higher class, a transmission zone corresponding to the Tx data is larger. As the Tx data has a lower class, the transmission zone corresponding to the Tx data is smaller.


Referring to FIG. 21, the controller 170 may configure different transmission zones according to the classes of Tx data.


When transmitting class-1 Tx data, the controller 170 may transmit the class-1 Tx data to a first transmission zone TZ1 by adjusting the transmission power of the communication device 400. For example, the controller 170 determines image data acquired through the camera 310 of the vehicle 100 to be class-1 data. When the controller 170 transmits the image data, the controller 170 adjusts the transmission power of the communication device 400 so that the Tx data may be transmitted to the first transmission zone TZ1. Accordingly, the second other vehicle 102 located within the first transmission zone TZ1 may receive the image data from the vehicle 100.


When transmitting class-2 Tx data, the controller 170 may transmit the class-2 Tx data to a second transmission zone TZ2 by adjusting the transmission power of the communication device 400. For example, the controller 170 determines sensing data acquired through various sensors of the vehicle 100 to be class-2 data. When the controller 170 transmits the sensing data, the controller 170 adjusts the transmission power of the communication device 400 so that the Tx data may be transmitted to the second transmission zone TZ2. Accordingly, the second other vehicle 102 and the first other vehicle 101 located within the second transmission zone TZ2 may receive the sensing data from the vehicle 100.


When transmitting class-3 Tx data, the controller 170 may transmit the class-3 Tx data to a third transmission zone TZ3 by adjusting the transmission power of the communication device 400. For example, the controller 170 determines a BSM of the vehicle 100 to be class-3 data. When the controller 170 transmits the BSM, the controller 170 adjusts the transmission power of the communication device 400 so that the Tx data may be transmitted to the third transmission zone TZ3. Accordingly, the second other vehicle 102, the first other vehicle 101, the third other vehicle 103, and the fourth other vehicle 104 located within the third transmission zone TZ3 may receive the BSM from the vehicle 100.


The vehicle 100 of the present disclosure transmits data of a higher class to a farther place, and data of a lower class to a nearer place, thereby reducing communication congestion.


According to another embodiment of the present disclosure, the controller 170 may set the size of a transmission zone in inverse proportion to a channel congestion degree based on information about the channel congestion degree.


Vehicle driving information may include information about the congestion degree of a channel used for V2X communication.


The congestion degree of a channel used for communication represents a ratio of a data transmission duration to a total time in a specific frequency bandwidth used for V2X communication. For example, as data is transmitted longer in the specific frequency bandwidth, it may be considered that the congestion degree of the channel increases.


The communication device 400 may be provided with an RF chipset for measuring a channel congestion degree.


The controller 170 may determine the congestion degree of the channel used for V2X communication based on information about the congestion degree of the channel.


The controller 170 may determine the size of a transmission zone based on information about the congestion degree of the channel.


The controller 170 may determine the size of the transmission zone in inverse proportion to the congestion degree of the channel.


For example, the controller 170 may configure a smaller transmission zone for a larger channel congestion degree. If the channel congestion degree is high, the controller 170 needs to reduce the channel congestion degree by decreasing the transmission zone in size.


For example, the controller 170 may configure a larger transmission zone for a lower channel congestion degree. If the channel congestion degree is low, it does not matter to increase the transmission zone in size.


Since the vehicle 100 of the present disclosure sets the size of a transmission zone to be inversely proportional to the congestion degree of a channel, communication congestion is reduced.


According to another embodiment of the present disclosure, the controller 170 determines an ROI for the vehicle 100 based on at least one of ambient situation information and vehicle state information, and configure a transmission zone such that the ROI is included in the transmission zone. The controller 170 determines the ROI in any of the methods descried before with reference to FIGS. 10 to 18.


The controller 170 may determine the size of a transmission zone so that the ROI may be included in the transmission zone.


When transmitting data by V2X communication, the communication device 400 broadcasts the data. Therefore, the shape of the transmission zone may be close to a circle with a radius being a distance corresponding to the transmission power of the communication device 400 with respect to a current location of the vehicle 100.


The controller 170 may determine the transmission power of the transmission device 400, which enables inclusion of the ROI in the transmission zone. The controller 170 transmits Tx data with the determined transmission power. The resulting configured transmission zone may include the ROI.


In this manner, as the vehicle 100 of the present disclosure enables transmission of the Tx data to the ROI, information about the vehicle 100 may be transmitted to another vehicle, a pedestrian, and infrastructure in the ROI.


According to another embodiment of the present disclosure, if determining that the vehicle 100 performs platoon driving, the controller 170 may determine the type of Tx data based on the location of the vehicle 100 in a vehicle platoon.


The controller 170 may determine whether the vehicle 100 performs platoon driving based on vehicle state information. The controller 170 may determine the location of the vehicle 100 in the vehicle platoon based on data received from another vehicle included in the same platoon.


For example, if determining that the vehicle 100 is a leading vehicle in the platoon, the controller 170 may transmit data related to what is ahead of the vehicle 100 to other vehicles in the same platoon. The data related to what is ahead of the vehicle 100 may be Rx data whose transmission position is determined to be ahead of the vehicle 100, and image data or sensing data acquired by a camera or a sensor provided on the front of the vehicle 100.


For example, if determining that the vehicle 100 is a trailing vehicle in the platoon, the controller 170 may transmit data related to what is behind the vehicle 100 to other vehicles in the same platoon. The data related to what is behind the vehicle 100 may be Rx data whose transmission position is determined to be behind the vehicle 100, and image data or sensing data acquired by a camera or a sensor provided on the rear of the vehicle 100.


For example, if determining that the vehicle 100 is neither a leading vehicle nor a trailing vehicle in the platoon, the controller 170 may transmit only a BSM of the vehicle 100 to other vehicles in the same platoon.


According to another embodiment of the present disclosure, the controller 170 may prioritize Rx data based on the types of other vehicles that have transmitted the Rx data or the types of object detection devices provided in the other vehicles.


The priority level of Rx data may be the priority level of using the Rx data in a specific computation or determination.


The controller 170 may determine the type of another vehicle that has transmitted Rx data or the type of an object detection device of the other vehicle, based on the Rx data.


For example, upon receipt of a plurality of sensing data, the controller 170 may prioritize the plurality of sensing data based on the specifications of sensors that have acquired the sensing data. The controller 170 may prioritize the plurality of sensing data in comprehensive consideration of the accuracies, sensitivities, and power of the sensors.


For example, upon receipt of a plurality of image data about what lies ahead, the controller 170 may prioritize the plurality of image data of what lies ahead according to the specifications of cameras that have acquired the image data or the types of other vehicles. For example, the controller 170 may prioritize the plurality of image data of what lies ahead in comprehensive consideration of the accuracies, sensitivities, and power of front cameras. For example, the controller 170 may prioritize the plurality of image data of what lies ahead in such a manner that image data of what lies ahead has a higher priority level if the height of another vehicle that has transmitted the image data is larger. This is because a taller vehicle captures an image of what lies ahead from a higher point, thus facilitating securing of the view of an image.



FIGS. 22A, 22B are views illustrating an operation for determining an output position of an alarm according to the transmission position of received data in a vehicle according to an embodiment of the present disclosure.


Referring to FIG. 22A, the vehicle 100 may include a plurality of display units.


The plurality of display units may include side mirror displays 251s disposed on both side mirrors, window displays 251h disposed on windows beside front seats, a windshield display 251c disposed on the windshield, a Center Information Display (CID) 251b disposed on the center of the instrument panel, and a room mirror display 251r disposed on a room mirror.


The controller 170 may generate an alarm based on Rx data in order to provide specific information to a user. For example, the alarm may be any of a collision alarm indicating collision with a specific object, a general alarm providing information about a specific object, and a special alarm indicating information that the user should be notified of.


The alarm may be a graphic object displayed on the display unit 251. For example, the alarm may be text or a figure image. The alarm may further include a sound output through the audio output unit 252.


The controller 170 may output the generated alarm to the output unit 250.


When the alarm is output to the plurality of display units 251, the controller 170 may select a display unit for outputting the alarm from among the plurality of display units 251 based on the Rx data based on which the alarm is generated (hereinafter, referred to as ‘alarm data’).


For example, the controller 170 may determine a display unit through which the alarm is to be output, based on the transmission position of the alarm data.


For example, if determining that the transmission position of the alarm data is within a right side zone RSZ of the vehicle 100, the controller 170 may output the alarm to the window display 251h disposed in a passenger's seat direction or the side mirror display 251s on the right side mirror.


For example, if determining that the transmission position of the alarm data is within a left side zone LSZ of the vehicle 100, the controller 170 may output the alarm to the window display 251h disposed in a driver seat direction or the side mirror display 251s on the left side mirror.


For example, if determining that the transmission position of the alarm data is within a front zone FZ of the vehicle 100, the controller 170 may output the alarm to the windshield display 251c or the CID 251b.


For example, if determining that the transmission position of the alarm data is within a rear zone RZ of the vehicle 100, the controller 170 may output the alarm to the room mirror display 251r.


As is apparent from the foregoing description, embodiments of the present disclosure have one or more effects.


First, since Rx data is filtered according to an ambient situation or a vehicle state, the filtering of the unnecessary data may reduce a communication load.


Secondly, a data transmission zone is adjusted according to an ambient situation or a vehicle state. Therefore, the congestion of a communication channel may be reduced.
