In particular, the vehicle 1 may communicate with the communication infrastructure 3 or the moving vehicle 2 using vehicle-to-everything (V2X) communication.
For example, the vehicle 1 may acquire various types of information, such as traffic information of a road, update information, and the like through communication with the communication infrastructure 3 (vehicle to infra communication: V2I), and may acquire various types of information, such as travelling information of another vehicle as well as traffic information and update information, through communication with the other vehicles (vehicle to vehicle communication: V2V).
The vehicle 1 may be provided with a separate V2X antenna (not shown) to communicate with the communication infrastructure 3 or the moving vehicle 2 using V2X communication. For example, the V2X antenna (not shown) may be installed at the rear of the roof of the vehicle 1 and may be installed near the front seats, such as on a head unit or a console box.
On the other hand, V2X communication may use a radio signal in a frequency band of about 5855 to 5895 MHz and a radio signal in a frequency band of about 5895 to 5925 MHz.
By using the V2X communication, the vehicle 1, the moving vehicle 2, and the communication infrastructure 3 may transmit and receive update information for updating the vehicle 1.

In this case, when update information is not received, the first controller 180 may control the first communicator 160 to receive update information for updating the electronic device from the moving vehicle 2 or the communication infrastructure 3.
In detail, the first controller 180 may control the first communicator 160 to transmit a request signal for requesting update information to the moving vehicle 2 or the communication infrastructure 3. When the update information corresponding to the request signal is received from the moving vehicle 2 or the communication infrastructure 3, the first controller 180 may perform an update on the electronic device on the basis of the received update information.

If it is determined that an update for the electronic device is required, the first controller 180 may update the electronic device on the basis of the received update information.
Meanwhile, with regard to receiving the update information from the moving vehicle 2 or the communication infrastructure 3, the first controller 180 may store the update information received in real time in the first storage 190.
While the update information is being received from the moving vehicle 2 or the communication infrastructure 3, communication disconnection may occur due to a change in the communication environment.
In this case, the first controller 180 may store only the update information having been received until the communication is disconnected in the first storage 190. Thereafter, the first controller 180 may continue receiving the update information from another moving vehicle 2 or the communication infrastructure 3, and store the update information in the first storage 190. Such a reception method is referred to a cumulative method.
In addition, the first controller 180 may control the first communicator 160 to receive update information in a single scheme or a diversity scheme according to the electric field situation. When the signal electric field is smooth, that is, when the communication is connected to both the moving vehicle 2 and the communication infrastructure 3, the first controller 180 may control the first communicator 160 to receive the update information in a diversity scheme.
Alternatively, when the communication is connected to any one of the moving vehicle 2 and the communication infrastructure 3, the first controller 180 may control the first communicator 160 to receive the update information in a single scheme. In this case, the first communicator 160 may receive the update information from the moving vehicle 2 or the communication infrastructure 3.
With regard to performing the update for the electronic device, the first controller 180 may determine the update order on the basis of device information of at least one device, and update the electronic device on the basis of the update order.
In this case, the device information refers to information required for performing an update on the electronic device, and includes at least one of a type of an update file required for performing an update on at least one electronic device, a size of the update file, a cumulative reception rate of the update file, or an importance of the update.
The importance of the update may be determined according to a predetermined priority or on the basis of a priority input by the user through the first input device 110.
For example, when a plurality of update files required for performing an update for the electronic device exist, the first controller 180 may determine an update order for the plurality of update files. The first controller 180 may determine the priority on the basis of at least one of the cumulative reception rate of the update file or the importance of the update. The first controller 180 may perform the update on the basis of the determined priority.
In this case, the first controller 180 may update the electronic device while the update information is being received. However, the present disclosure is not limited thereto, and the first controller 180 may update the electronic device after all the update information is received.
When the update for the electronic device is required, the first controller 180 may determine whether to switch the traveling route on the basis of at least one of device information of the electronic device or route information of the moving vehicle 2.
In this case, the device information refers to information required for performing an update on the electronic device, and may include at least one of a type of an update file required for performing an update on the electronic device, a size of the update file, a cumulative reception rate of the update file, or an importance of the update. The route information of the moving vehicle 2 may be received from the moving vehicle 2 or may be stored in the first storage 190 in advance.
In detail, the first controller 180 may determine whether to switch the travelling route on the basis of the route information of the moving vehicle 2 which transmits update information having a higher importance.
For example, in a state in which the importance of the update for device-A is given the first priority, and the importance of the update for device-B is given the second priority, if the route information of the moving vehicle 2 that transmits update information for updating the device-A matches the travelling route at a rate equal to or greater than a predetermined reference value, the first controller 180 may determine not to switch the travelling route. That is, the first controller 180 may determine to maintain the travelling route.
If the route information of the moving vehicle 2 that transmits update information for updating the device-A matches the travelling route at a rate less than the predetermined reference value, the first controller 180 may determine to switch the travelling route.
If it is determined that the travelling route is not to be switched, the first controller 180 may maintain the existing route and receive update information from the moving vehicle 2 or the communication infrastructure 3, and update the electronic device that needs to be updated.
If it is determined that the travelling route is to be switched, the first controller 180 determines an optimal route on the basis of at least one of the device information of the vehicle 1 or the route information of the moving vehicle 2, and provides the user with the determined optimal route.
In this case, the optimal route may refer to a route capable of maintaining communication for updating the electronic device, and may refer to a route capable of maintaining communication with the moving vehicle 2 or the communication infrastructure 3 for a predetermined time.
To this end, the first controller 180 may determine a target vehicle among the moving vehicles 2 located within a predetermined area from the vehicle 1 and determine an optimal route on the basis of route information of the target vehicle.
In detail, the first controller 180 may determine a moving vehicle 2 among the at least one moving vehicle 2 within a predetermined area from the vehicle 1, which has route information similar to the travelling route of the vehicle 1 at a degree equal to or greater than a predetermined value, as a target vehicle, and may determine the optimal route on the basis of the route information of the target vehicle.
In another form, the first controller 180 may determine a moving vehicle 2 having route information that is the most similar to the travelling route of the vehicle 1 among the at least one moving vehicle 2 within a predetermined area from the vehicle 1 as a target vehicle, and may determine the optimal route on the basis of route information of the target vehicle.
To this end, the first controller 180 may receive route information from a respective moving vehicle of the at least one moving vehicle 2 located in the predetermined area from the vehicle 1. The route information of each moving vehicle 2 may be received together with the update information.
The first controller 180 may provide the user with the determined optimal route through the first display 120 such that the user travels in the optimal route.
In other form, the first controller 180 may control the first driver 170 to switch the travelling route to the determined optimal route, and perform autonomous driving on the basis of the optimal route. In this case, the travelling route is automatically switched to the optimal route, and the vehicle 1 may travel on the optimal route.
Since the communication with the moving vehicle 2 or the communication infrastructure 3 is maintained during the travelling according to the optimal route, the first controller 180 may receive the update information from the moving vehicle 2 or the communication infrastructure 3, and update the electronic device on the basis of the received update information.
With this configuration, the first controller 180 may reliably receive update information from the moving vehicle 2 or the communication infrastructure 3, and efficiently update the electronic device.
In addition, the first controller 180 may check whether the update for the electronic device is completed, and if the update for the electronic device is not completed, may control the first communicator 160 to transmit a signal for requesting the update information to the moving vehicle 2 or the communication infrastructure 3.
In this case, the first controller 180 may transmit the signal for requesting the update information to the moving vehicle 2 located in a predetermined area or the communication infrastructure 3. When the update information is received in response to the request signal, the first controller 180 may continue updating the electronic device.
Accordingly, the wireless update is efficiently performed regardless of the communication area, so that the user convenience is increased.

The route information may be received from the communication infrastructure 3 or may be stored in advance at a time of design.
The second storage 290 may be implemented as at least one of a nonvolatile memory device, a volatile memory device, or a storage medium, but the implementation is not limited thereto. The description of the second storage 290 is the same as that of the first storage 190. The second storage 290 may be a memory implemented as a chip separated from a processor 281 which will be described below with respect to the second controller 280, or may be implemented as a single chip integrated with the processor 281.
The second controller 280 include a memory 282 storing programs and data for controlling travelling and/or communication of the moving vehicle 2 and the processor 281 that generates a signal for controlling the traveling and/or communication of the moving vehicle 2 on the basis of the programs and data stored in the memory 282.
The memory 282 may not only include a volatile memory device, such as a SRAM and a D-RAM, but also include a nonvolatile memory device, such as a flash memory, a read only memory (ROM), an erasable programmable ROM (EPROM), and the like.
The processor 281 may include a main processor that controls travelling of the moving vehicle 2, a communication processor that controls communication of the moving vehicle 2, an image processor that processes an image of the second camera 240, and the like.
The second controller 280 is provided in the moving vehicle 2, and controls various drivers 270 and additional devices provided in the moving vehicle 2. The second controller 280 may represent a controller provided in an autonomous driving control device for autonomous driving.
The second controller 280 may control autonomous driving of the moving vehicle 2 on the basis of image information of the second camera 240, detection information of the second detector 230, location information of the second GPS 250, and information received through the second communicator 260.
The second controller 280 may control the second driver 270 to travel on the basis of predetermined route information.
The second controller 280 may control the second communicator 260 to transmit update information for updating at least one electronic device received from the communication infrastructure 3 to an external device.
The second controller 280 may transmit the update information to a neighboring vehicle located within a predetermined range. In this case, the predetermined range may refer to a range in which V2X communication is performable, and the neighboring vehicle may include at least one of other moving vehicles 2 or the vehicle 1.
The second controller 280 may control the second communicator 260 to transmit the update information to at least one neighboring vehicle located within the predetermined range while travelling on the basis of the predetermined route information.
In this case, the second controller 280 may transmit the route information along with the update information to vehicles located within the predetermined range.
In one form, the second controller 280 may control the second communicator 260 to transmit the update information to the vehicle 1 in response to receiving a request signal for the update information from the vehicle 1.
As such, the second controller 280 may serve as a relay between the communication infrastructure 3 and the neighboring vehicle by transmitting the update information received from the communication infrastructure 3 or stored in advance. With this configuration, even when the neighboring vehicle does not receive update information from the communication infrastructure 3, the neighboring vehicle may receive the update information if the neighboring vehicle is within a predetermined range from the travel route of the moving vehicle 2. Accordingly, the update efficiency of the neighboring vehicle may be increased, and the user convenience may also be increased.
In addition, the second controller 280 may transmit traffic information to the communication infrastructure 3 while traveling on the basis of the predetermined route information. In this case, the traffic information may refer to information with which a traffic environment is estimated, and may include information regarding traffic accidents, traffic conditions, and the like.
To this end, the second controller 280 may generate the traffic information on the basis of data acquired by the second detector 230, the second camera 240, or the second GPS 250. Alternatively, the second controller 280 may acquire the traffic information by receiving the traffic information generated by the first detector 130, the first camera 140, or the first GPS 150 of the vehicle 1 from the vehicle 1.
With this configuration, immediate update of traffic situation information may be performed, and the communication infrastructure 3 may provide traffic information suitable for a real-time traffic situation.
The receive sensitivity according to the conventional communication method generally decreases as the distance from the center of a communication infrastructure increases.
Referring to
Accordingly, the receive sensitivity of an area X distant from the centers of the base station-A and the base station-B may be lower than a V2V communication packet error rate (PER) reference receive sensitivity. In this case, a V2V communication failure may occur.
However, with the communication method of the vehicle 1 according to one form of the form, the moving vehicle 2 traveling along a predetermined route serves as a repeater, so that the receive sensitivity of the area X distant from the centers of the base stations A and B may have a value greater than the V2V communication PER reference receive sensitivity.
That is, even when the vehicle 1 is located in the area X distant from the centers of the base stations A and B, the vehicle 1 communicates with the base station-A or the base station-B via the moving vehicle 2 located in the base station-A or the base station-B.
As such, V2V communication is maintained regardless of the location of the base station, so that the efficiency of the communication may be increased. At the same time, since the V2V communication is smoothly maintained, the user convenience may be increased in providing a convenience function using the V2V communication.
In addition, since the wireless update for the vehicle 1 is efficiently performed in the city area and the suburb area, the user satisfaction is improved by providing the latest functions.
Referring to
Upon receiving the update information (Yes in operation 501), the vehicle 1 may determine whether software update is required (502). In detail, the vehicle 1 may determine whether software update for at least one electronic device installed in the vehicle 1 is required. The vehicle 1 may check the version of software of various electronic devices installed in the vehicle 1, and if the checked version is not the latest version, determine that a software update is required.
If a software update for at least one electronic device is required (YES in operation 502), the vehicle 1 may perform a software update on the basis of the received update information (503).
In order to perform the software update, the vehicle 1 may determine an update order on the basis of device information of the at least one device, and update the electronic device on the basis of the update order.
In this case, the device information refers to information required for performing an update on the electronic device, and includes at least one of a type of an update file required for performing an update on at least one electronic device, a size of the update file, a cumulative reception rate of the update file, or an importance of the update. The importance of the update may be determined according to a predetermined priority or on the basis of a priority input by the user through the first input device 110.
For example, when a plurality of update files required for performing an update for the electronic device exist, the vehicle 1 may determine an update order for the plurality of update files. The vehicle 1 may determine the priority on the basis of at least one of the cumulative reception rate of the update file or the importance of the update. The vehicle 1 may perform the update on the basis of the determined priority.
With this configuration, since the vehicle 1 performs the update using the update information received from the moving vehicle 2 or the communication infrastructure 3, the wireless update may be efficiently performed regardless of the communication area. Accordingly, the user convenience may be increased.
Referring to
If software update is required (Yes in operation 601), the vehicle 1 may transmit an update request to the moving vehicle 2 located in a surrounding of the vehicle 1 or the communication infrastructure 3 (602). In detail, the vehicle 1 may perform an update request by transmitting a signal for requesting update information for the electronic device that requires update to the moving vehicle 2 or the communication infrastructure 3. In this case, the vehicle 1 may transmit the signal for requesting the update information to the moving vehicle 2 located in a predetermined area or the communication infrastructure 3.
The vehicle 1 may determine whether to switch a route on the basis of at least one of device information of the electronic device or route information of the moving vehicle 2 (603).
In this case, the device information refers to information required for performing an update on the electronic device, and includes at least one of a type of an update file required for performing an update on the electronic device, a size of the update file, a cumulative reception rate of the update file, or an importance of the update. The route information of the moving vehicle 2 may be received from the moving vehicle 2 or may be stored in advance in the vehicle 1.
In detail, the vehicle 1 may determine switching of the travelling route on the basis of route information of the moving vehicle 2 that transmits update information having a higher importance.
For example, in a state in which the importance of the update for a device-A is given the first priority, and the importance of the update for a device-B is given the second priority, if the route information of the moving vehicle 2 that transmits update information for updating the device-A matches the travelling route at a rate equal to or greater than a predetermined reference value, the vehicle 1 may determine not to switch the travelling route. That is, the vehicle 1 may determine to maintain the travelling route.
If the route information of the moving vehicle 2 that transmits update information for updating the device-A matches the travelling route at a rate less than the predetermined reference value, the vehicle 1 may determine to switch the travelling route.
If it is determined that the route is to be switched (YES in operation 604), the vehicle 1 may search for the optimal route on the basis of at least one of the device information of the vehicle 1 or the route information of the moving vehicle 2 (607). In this case, the optimal route may refer to a route capable of maintaining communication for updating the electronic device, and may refer to a route capable of maintaining communication with the moving vehicle 2 or the communication infrastructure 3 for a predetermined time.
To this end, the vehicle 1 may determine a target vehicle among the moving vehicles 2 located within a predetermined area from the vehicle 1 and determine an optimal route on the basis of route information of the target vehicle.
In detail, the vehicle 1 may determine a moving vehicle 2 among the at least one moving vehicle 2 within a predetermined area from the vehicle 1, which has route information similar to the travelling route of the vehicle 1 at a degree equal to or greater than a predetermined value, as a target vehicle, and may determine the optimal route on the basis of the route information of the target vehicle.
In one form, the vehicle 1 may determine a moving vehicle 2 having route information that is the most similar to the travelling route of the vehicle 1 among the at least one moving vehicle 2 within a predetermined area from the vehicle 1 as a target vehicle, and may determine the optimal route on the basis of the route information of the target vehicle.
Thereafter, the vehicle 1 may travel on the determined optimal route (608), and may perform software update for at least one electronic device while travelling on the optimal route (609). In this case, since the communication with the moving vehicle 2 or the communication infrastructure 3 is maintained during the travel along the optimal route, the vehicle 1 may receive update information from the moving vehicle 2 or the communication infrastructure 3, and update the electronic device on the basis of the received update information.
With this configuration, the vehicle 1 may stably receive update information from the moving vehicle 2 or the communication infrastructure 3, and efficiently update the electronic device.
As another example, when it is determined that the travelling route is not to be switched (NO in operation 604), the vehicle 1 may travel on the existing route (605). By maintaining the existing route, the vehicle 1 may receive update information from the moving vehicle 2 or the communication infrastructure 3 and perform software update for the electronic device that needs to be updated (606).
After the software update (606 or 609), the vehicle 1 may check whether the update for the electronic device is completed (610), and if the update for the electronic device is not completed (NO in operation 610), operations 601 to 609 are repeated to continue the update for the electronic device.
Accordingly, the wireless update is efficiently performed regardless of the communication area, so that the user convenience is increased.
As is apparent from the above, the vehicle and the method of controlling came can increase the user convenience by efficiently updating an electronic device.
