With reference to
The proximity communication module 810 is configured to perform wired and wireless communications with the various constituent elements that are described with reference to
The proximity communication module 810 performs communication with a terminal that is positioned within a predetermined distance from a vehicle. For example, the processor 830 searches for a terminal that is positioned inside of the vehicle 100 and performs the communication with the found terminal using the proximity communication module 810. In other words, the proximity communication module 810 is configured to perform the communication with one or more terminals that are positioned inside of the vehicle 100.
The proximity communication module 810 is a device that is capable of performing the communication with the terminal that is positioned inside of the vehicle 100. No limitation is imposed on a method of performing the communication. For example, the proximity communication module 810 may perform the communication in a wired manner or may perform the communication in a wireless manner using various communication standards such as Bluetooth or WiFi.
The term “proximity” in the proximity communication module 810 is a relative term, and means a shorter distance than does the term “wide area” in a wide area communication module 930 or 1030 that will be described below. In other words, it is assumed that the proximity communication module 810 can perform the communication with the terminal that is positioned inside of the vehicle 100, but that the proximity communication module 810 cannot perform other communication devices that are positioned outside of the vehicle 100. It is assumed that the proximity communication module 810 cannot perform the communication with other communication devices which are positioned outside of the vehicle 100 due to a restriction of a communication-available range or a restriction of an available communication standard.
The proximity communication module 810 receives information relating to vehicle's traveling from most of the devices that are installed in the vehicle 100. The information that is transmitted from the vehicle 100 to the vehicle control device 800 is referred to as vehicle traveling information.
The vehicle traveling information includes vehicle information and vicinity-of-a-vehicle information. When a body of the vehicle 100 is used as a reference, information relating to the inside of the vehicle is defined as the vehicle information and information relating to the outside of the vehicle is defined as the vicinity information.
The vehicle information means information relating to the vehicle itself. For example, pieces of vehicle information include a traveling speed of the vehicle, a traveling direction of the vehicle, acceleration of the vehicle, an angular speed of the vehicle, a location (GPS) of the vehicle, a weight of the vehicle, the number of people on board, braking power of the vehicle, maximum braking power of the vehicle, pneumatic pressure of each of the wheels of the vehicle, a centrifugal force that is applied to the vehicle, a traveling mode (an autonomous traveling mode or a manual traveling mode) of the vehicle, a parking mode (an autonomous parking mode, an automatic parking mode, or a manual parking mode) of the vehicle, information as to whether or not a user rides in the vehicle, and information relating to the user.
The vicinity information means information relating to an object that is positioned within a predetermined from the vehicle, and information relating to the outside of the vehicle. For example, pieces of vicinity information include a state (a frictional force) of a road on which the vehicle is traveling, weather, a distance to a preceding (or following) vehicle, a relative speed of the preceding (or following) vehicle, a curvature of a curve in a case where a lane on which the vehicle is traveling is curved, the brightness of an area in the vicinity of the vehicle, information relating to an object that is present within a reference area (fixed area) from the vehicle, information as to whether an object moves into or out of the fixed area, information as to whether a user is present in the vicinity of the vehicle, information relating to the user (for example, information as to whether or not the user is an authenticated user).
In addition, the pieces of vicinity information include ambient brightness, ambient temperature, a sun position, information (a person, another vehicle, a road sign, or the like) relating to an object that is positioned in the vicinity of the vehicle, a type of road on which the vehicle is traveling, a geographic feature, information relating to lines marked on a road on which the vehicle travels, and vehicle-traveling lane information, and information necessary for an autonomous traveling, autonomous parking, automatic parking, or manual parking mode.
In addition, the pieces of vicinity information further include a distance from the vehicle 100 to an object present in the vicinity of the vehicle 100, the likelihood of colliding with the object, a type of the object, a parking space that is available for parking the vehicle, an object (for example, a marked parking line, a string indicating the parking space, a parked vehicle, a wall, or the like) for identifying the parking space.
The pieces of vehicle traveling information are not limited to the examples described above, and include all pieces of information that are generated from constituent elements that are installed in the vehicle 100.
On the other hand, the processor 830 is configured to control one or more displays, which are installed in the vehicle 100, using the proximity communication module 810.
Specifically, based on the vehicle traveling information that is received through the proximity communication module 810, the processor 830 determines whether or not, among a plurality of conditions that are preset, at least one condition is satisfied. According to the condition that is satisfied, the processor 830 controls the one or more displays in different ways.
Regarding the preset condition, the processor 830 detects that an event occurs in electronics and/or an application that are installed in the vehicle 100, and determines whether or not the detected event satisfies the preset condition. At this time, the processor 830 may detect that the event occurs, from information that is received through the proximity communication module 810.
The applications conceptually include a widget and a home launcher and are meant to include all types of programs that are possibly executed in the vehicle 100. Therefore, the application may be a web browser or a program that performs moving image reproduction, message transmission and reception, scheduling, or application update.
Furthermore, the application includes at least one of the following: forward collision warning (FCW), blind spot detection (BSD), lane departure warning (LDW), pedestrian detection (PD), curve speed warning (CSW), and turn-by-turn navigation (TBT).
For example, the event occurs in a case where there is a missed call, in a case where an application that is a target for update is present, in a case where a message arrives, in a case where a vehicle starts on or starts off, in a case where an autonomous traveling mode is turned on or off, in a case where an LCD awake key is held down, in a case where there is an alarm, an incoming call, a missed notification, and the like.
As another example, the event occurs in a case where a warning that is set in an advanced driver assistance system (ADAS) occurs or where a function that is set in the ADAS is performed. For example, the event is regarded as occurring, in a case where the forward collision warning occurs, in a case where a backward sideways warning (the blind spot detection) occurs, in a case where the lane departure warning occurs, in a case where a lane keeping assist warning occurs, and in a case where autonomous emergency braking is performed.
As another example, the event is also regarded as occurring, in a case where gear shifting from a forward gear to a reverse gear is performed, in a case where acceleration that is greater than a predetermined value occurs, or in a case where a power generation apparatus is changed from an internal combustion engine to a motor or from the motor to the internal combustion engine.
In addition, the event is also regarded as occurring, in a case where various ECUs that are installed in the vehicle 100 perform specific functions. In a case where the event that occurred satisfies a preset condition, the processor 830 controls the proximity communication module 810 in such a manner that information corresponding to the satisfied condition is displayed on one or more displays.
Based on the vehicle traveling information, the processor 830 generates an autonomous traveling command in such a manner that the vehicle 100 autonomously travels. For example, the autonomous traveling command is generated in such a manner that, although a driver does not correspondingly drive a vehicle, according to an algorithm, a traveling direction is changed, a speed is changed, or braking is performed.
On the other hand, in order to ensure safer autonomous traveling, information needs to be received from various communication devices that are positioned outside of the vehicle 100, and information that is generated inside of the vehicle 100 needs to be corrected or synchronized using the received information. This is because a physical restriction of a memory that is installed inside of the vehicle 100 is always present, there is always a likelihood that an error will occur, and so forth.
In order to perform communication with a communication device that is positioned outside of the vehicle 100, a mobile communication service, like one in the field of telematics, needs to be provided. There is a problem in that a communication module for providing the mobile communication service is installed in order to providing the mobile communication service.
In a state where the communication module that provides the mobile communication service is not provided, the vehicle control device 800 according to the present disclosure performs communication with various communication devices 1000 that are positioned outside of the vehicle 100, using a terminal 900 that is positioned inside of the vehicle 100. In other words, the vehicle control device 800 uses the terminal 900, which is positioned inside of the vehicle 100, as a relay means of, or a communication means of providing the mobile communication service.
The “terminal 900” is hereinafter defined as a device that is positioned inside of the vehicle 100 and performs communication through the proximity communication module 810 of the vehicle control device 800.
The terminals 900 include a portable phone, a smartphone, a laptop computer, a digital-broadcast-dedicated terminal, a personal digital assistant (PDA), a portable multimedia player (PMP), a navigation system, a slate PC, a tablet PC, a high-end subnotebook computer such as an Ultrabook (a registered trademark) subnotebook computer, and a wearable device (for example, a watch-type terminal (smart watch), a glass-type terminal (smart glass), or a head mounted display (HMD)).
The “communication device 1000” is defined as a device that is positioned outside of the vehicle 100 and performs communication with the vehicle control device 800 through the terminal 900.
The communication devices 1000 include all devices that are positioned outside of the vehicle 100 and performs the communication. For example, the terminal 900, when positioned outside of the vehicle 100, corresponds to the communication device 1000. In addition, a communication base station, a server, a vehicle, a traffic signal lamp, or the like corresponds to the communication device 1000.
The terminal 900 includes a proximity communication module 910 and a wide area communication module 930. The proximity communication module 910 is configured to perform the communication with the vehicle control device 800, and the wide area communication module 930 is configured to perform communication with the communication device 1000. The proximity communication module 910 and the wide area communication module 930 may be arranged, as different modules, inside of the terminal 900, or may be integrally realized as a single chip.
The communication device 1000 includes a wide area communication module 1030 and performs communication with the terminal 900 using the wide area communication module 1030.
Operation of the vehicle control device 800 will be described in more detail below with reference to the accompanying drawings.
The processor 830 of the vehicle control device 800 selects any one terminal from among terminals that are positioned inside of the vehicle 100, according to a preset reference.
The processor 830 searches for one or more terminals that are positioned inside of the vehicle 100. Then, any one terminal is selected from among the found terminals according to the preset reference.
The processor 830 calculates an evaluation value for each terminal based on one or more evaluation factors that are set according to the preset reference, and selects at least one terminal, the calculated evaluation value for which is greater than a reference evaluation value.
The evaluation factors include a communication speed of each terminal, an amount of available data, an amount of available battery power, a position of each terminal that is placed inside of the vehicle 100, a size of a display that is installed in each terminal, and an interworking history of the vehicle control device 800.
The reference evaluation value varies according to a traveling environment where the vehicle 100 is traveling. The traveling environment relates to a speed of the vehicle 100, properties of a road on which the vehicle 100 is traveling, and weather. For example, when it is sunny, the reference evaluation value is a first value, and when it rains, the reference evaluation value changes to a second value that is higher than the first value. This is in order to increase a value of a reference for selecting a terminal to provide the safer autonomous traveling.
A process of selecting any one of the terminals is performed periodically, occasionally, or in real time. Although the same terminals are positioned inside of the vehicle 100, which one of the same terminals is selected depends on a point in time when the selection is performed.
For example, in a case where an amount of available data in a first terminal is 1 TB and an amount of available data in a second terminal is 1 GB, the first terminal is selected. Subsequently, the communication with the communication device 1000 is performed through the wide area communication module that is installed in the first terminal. Due to the continuous use of the data, the amount of available data is smaller than 1 GB. In this case, the processor 830 selects the second terminal instead of the first terminal, and performs the communication with the communication device 1000 using the wide area communication module of the second terminal.
In a case where a plurality of terminals satisfy the preset condition, the plurality of terminals are possibly selected. The case where the plurality of terminals are selected will be described in detail below with reference to
With reference back to
More specifically, the processor 830 controls the proximity communication module 810 in such a manner that the communication with the communication device 1000 is performed. The terminal 900 performs the communication with the communication device 1000 using the wide area communication module 930 of the terminal 900 itself, and transmits information, as is, which is received from the communication device 1000, to the vehicle control device 800 or transmits information, which results from processing the received information in a predetermined way, to the vehicle control device 800.
The terminal 900 performs a car mode for transmitting to the vehicle control device 800 the information that is received from the communication device 1000. The car mode here means a mode for using the terminal 900 as a communication means for the vehicle control device 800, and is defined as a mode for allocating to the vehicle control device 800 the highest priority in using a resource that is available to the terminal 900.
In a case where the car mode is performed, the terminal 900 performs communication with various devices that are installed inside of the vehicle 100. The terminal 900 performs communication not only with the vehicle control device 800, but also with the various constituent elements that are described with reference to
Devices that are mounted in the vehicle 100 perform communication using the controller area network (CAN) that are standardized. A data protocol is stipulated for the CAN communication, and a status field in the data protocol includes an identifier of an entity that performs communication. Only in a case where the identifier is valid, the CAN communication is performed and communication security is ensured by the identifier.
The vehicle control device 800 assigns the terminal 900 a communication identifier specific to the terminal 900 itself in such a manner that the terminal 900 possibly performs communication in compliance with the data protocol. The terminal 900 generates data for the CAN communication or selectively uses information that is received through the vehicle control device 800, using the communication identifier that is assigned to the terminal 900 itself.
The processor 830 provides various functions using information that is transmitted from the communication device 1000 and is received through the vehicle control device 800.
As an example, the processor 830 generates the autonomous traveling command in such a manner that the vehicle 100 travels autonomously, using the information that is received the selected terminal (S950).
The processor 830 instructs the terminal 900 to receive high-precision map data that supports the autonomous traveling, using the proximity communication module 810. The terminal 900 searches for a device that provides the high-precision map data, or makes a request to a preset device for the high-precision map data. At this time, a device to which the terminal 900 makes a request for the high-precision map data corresponds to the communication device 1000. The high-precision map data is transmitted to the communication device 1000, the terminal 900, and the vehicle control device 800 in this order, and the processor 830 generates the autonomous traveling command using the high-precision map data.
In addition, the processor 830 provides various functions using the information that received from the communication device 1000.
Next, the processor 830 controls the proximity communication module 810 in such a manner that, while the autonomous traveling command is being generated, performing of at least one function is limited in the selected terminal (S970).
In a case where the car mode is performed, the terminal 900 categorizes a plurality of applications that are installed in the terminal 900, into a first group that includes executable applications and a second group that includes non-executable applications. The plurality of applications may be categorized into the first group and the second group according to at least one of the following: an amount of battery power per unit time, an amount of data used and a resource occupancy rate.
Executing of an application that is included in the second group is limited even in a case where the user inputs an execution request. The terminal 900 outputs alert information that alerts the user to execution restriction at least in one of the following ways: visual, acoustic, and tactile ways.
The processor 830 controls the proximity communication module 810 in such a manner that the car mode is performed in the selected terminal and, at the same time or thereafter, at least one function among functions that are being performed in the selected terminal is interrupted. For example, when an application that is included in the second group is being executed, the car mode is performed and then execution of the application is interrupted. This is in order to manage a resource in such a manner that the terminal 900 operates as a communication means for the vehicle control device 800.
As described above, the vehicle control device 800 according to the present disclosure causes the vehicle 100 to serve as a vehicle that provides a V2V function and/or a V2X function, using a communication network of the terminal that is positioned inside of the vehicle 100.
In the case where the plurality of terminals that are positioned inside of the vehicle are found, the first terminal and the second terminal are set to be a main terminal and a sub-terminal, respectively (S1010).
Based on one or more evaluation factors that are set for the preset reference, the processor 830 calculates an evaluation value for each terminal, sets a terminal with the first highest priority to be the main terminal, in order of decreasing a size of the calculated evaluation value, and set a terminal with the second highest priority to be the sub-terminal.
The main terminal is defined as a terminal that performs the car mode, and the sub-terminal is defined as a terminal that is on standby in order to be always ready for performing the car mode.
The processor 830 performs the communication with the communication device 1000 that is positioned outside of the vehicle 100, using the main terminal (S1030). More specifically, the proximity communication module 810 is controlled in such a manner that information is received from the communication device 1000 through a wide area communication module that is installed in the main terminal.
Next, in a case where a state that is pre-defined is detected in the main terminal, the processor 830 performs the communication with the communication device using the sub-terminal instead of the main terminal (S1050).
Specifically, the processor 830 monitors the main terminal while the communication is being performed using the main terminal. It is determined through the monitoring whether or not the main terminal reaches the pre-defined state where the communication can be performed.
The pre-defined state here refers to a case where an amount of available battery power in the main terminal is smaller than a reference amount of battery power, a case where an amount of available data in the main terminal is smaller than a reference amount of data, a case where a level of communication sensitivity of the main terminal is lower than a level of reference sensitivity, or the like. That is, the pre-defined state means a state where, using the main terminal, the autonomous traveling by the vehicle is not possible or the mobile communication service can be provided.
In a case where the pre-defined state is detected, the processor 830 controls the proximity communication module 810 in such a manner that the communication with the communication device 1000 is performed using a wide area communication module which is installed in the sub-terminal, instead of the main terminal.
The processor 830 controls the proximity communication module 810 in such a manner that a function which is performed using the main terminal is continuously performed by the sub-terminal in a seamless way. This is because temporary interruption of the reception of information that is to be received during the autonomous traveling results in a vehicle accident.
As an example, the processor 830 controls the proximity communication module 810 in such a manner that, before using the sub-terminal, information which is received from the main terminal is transmitted to the sub-terminal. The sub-terminal searches for a suitable synchronization point in time while monitoring information that is transmitted by the main terminal, and transmits the found point in time to the vehicle control device 800. At the point in time that is received from the sub-terminal, the vehicle control device 800 releases the connection to the main terminal, and performs the communication with the communication device 1000 using the sub-terminal.
As another example, the processor 830 determines a first point in time (t) at which the communication with the main terminal is finished, and calculates a second point in time (t+n) that is necessary for the sub-terminal to perform synchronization, from the first point in time (t). The processor 830 requests the communication device 1000 to transmit data that is predicted to be received from the first point in time (t) to the second point in time (t+n), until the first point in time (t). The data is received in advance and thus preparation is made for the temporary interruption of the communication.
As another example, in a case where the pre-defined state is detected in the main terminal, the processor 830 performs the communication with the communication device 1000 using both the main terminal and the sub-terminal. The processor 830 gradually increases an amount of communication with the sub-terminal, and decreases an amount of communication with the main terminal in proportion to this gradual increase, thereby ending the communication with the main terminal. For example, in a first section in which the pre-defined state is detected, a ratio of the amount of communication with the sub-terminal to the amount of communication with the main terminal is set to 9:1, and in a second that follows the first section, the ratio is set to 7:3.
The processor 830 calculates an amount of data per unit time, which is communicated uses the wide area communication module of the main terminal. In a case where the calculated amount of communicated data is greater than a maximum reference or is smaller than a minimum reference, the communication with the communication device 1000 is performed using both the wide area communication module of the main terminal and the wide area communication module of the sub-terminal. In other words, in a case where the use of only the main terminal causes the amount of communicated data to be insufficient, the processor 830 uses the sub-terminal, along with the main terminal, and thus compensates for the insufficient amount of communicated data.
The car mode is performed in the sub-terminal that is on standby before the car mode is performed, and thus an application that is being executed in the sub-terminal is automatically no longer executed. In addition, the processor 830 controls the proximity communication module 810 in such a manner that the performing of at least one function is limited in the standby state and/or in a state where the car mode is performed.
In a case where the pre-defined state is no longer available in the main terminal, the processor 830 performs the communication with the communication device 1000, resuming the use of the main terminal (S1070).
In the case where the pre-defined state is no longer available, the processor 830 controls the proximity communication module 810 in such a manner that the communication with the communication device 1000 is performed using the wide area communication module which is installed in the main terminal instead of the sub-terminal. In other words, the sub-terminal plays a role of the main terminal tentatively or temporarily, and, when the main terminal is no longer in the pre-defined state, returns to the standby state.
On the other hand, although not illustrated, in a case where a first function is performed, the processor 830 selects a first terminal from among one or more terminals, according to a first reference that is set for the first function. Furthermore, in a case where a second function is performed, the processor 830 selects a second terminal that is different from the first terminal, from among the one or more terminals, according to a second reference that is set for the second function.
According to a function that needs to be performed or is being performed, an optimal reference for a terminal that supports the function varies. The processor 830 selects any one terminal that is optimized for a function that is currently being performed, as the main terminal, using various references.
For example, the first terminal performs communication at a higher speed than a second terminal, and the second terminal has a larger display than the first terminal. The processor 830 performs the communication with the communication device using the first terminal, in a case where the communication needs to be performed at a high speed, and performs the communication with the communication device using the second terminal, in a case where the terminal needs to have a large display.
On the other hand, in a situation where the sub-terminal is not present, the pre-defined state of the main terminal is detected. In this case, the processor 830 calculates time at which the autonomous traveling is possible and alerts a person who rides in the vehicle that the autonomous traveling is finished at the calculated time. In a case where it is impossible for the main terminal to provide the mobile communication service, switching to manual traveling is guided.
The terminal 900 performs the car mode at the request of the vehicle control device 800 while providing a function of a normal terminal.
When the car mode is performed, the performing of at least one function is limited in the terminal 900. Therefore, before performing the terminal 900 alerts the user to the time that it takes to perform the car mode, or provides detailed information on the function, the performing of which is limited.
As illustrated in
In order to ensure stable communication through the terminal 900, the terminal 900 needs to be held in place to be positioned at a predetermined position. To eliminate this need, a cradle 1310 for holing the terminal 900 in place to be positioned at the predetermined position is installed inside of the vehicle 100.
The cradle 1310 and the operation of the vehicle control device 800 that uses the cradle 1310 will be described in detail below with reference to
First, with reference to
The cradle 1310 includes a first portion, a second portion, and a third that connects the first and second portions to each other. The first portion is exposed to the outside and a front-surface portion of the terminal 900 is brought into contact with the first portion. A rear-surface portion of the terminal 900 is brought into contact with the second portion. The third portion limits movement of the terminal 900 in such a manner that the terminal 900 is not slid in the direction of gravity.
The terminal 900 is slidably moved in one direction for insertion between the first portion and the second portion, and is placed in the third portion or is supported by the third portion.
The first portion is formed in such a manner that it does not cover a screen display area of the terminal 900. For example, the width of the first portion is 20 mm to 50 mm. This corresponds to a size of a bezel area of the terminal 900.
The terminal 900 in a state of being placed in the cradle 1310 is slidably moved leftward and rightward toward the leftmost end or rightmost end of the display unit 251.
On the other hand, the cradle 1310 further includes holding portions 1320 and 1330 that are configured to hold the terminal 900 in place to be positioned at a proper position when the terminal 900 is inserted.
As an example, as illustrated in
As another example, as illustrated in
With reference to
For example, in a case where a wireless charging unit that is positioned on the rear surface of the display unit 251 and supplies power wirelessly to the terminal 900 is activated, the processor 830 determines that the terminal 900 is placed in the cradle 1310.
As another example, it is detected whether or not the terminal 900 is placed, in various cases, such as a case where the holding unit 1320 applies pressure and a case where it is detected that the terminal 900 is detected from an image of the display unit 251, which is captured by a camera.
In a case where the terminal 900 is placed in the cradle 1310, the processor 830 controls the holding portions 1320 and 1330 in such a manner that the holding portions 1320 and 1330 hold the terminal 900 in place (S1230).
For example, in a case where the holding portion 1320 has electricity, the holding portion 1320 exerts an external force in one direction on the terminal 900. Furthermore, in a case where the holding portion 1330 is slidably moved, the first and second holding portions of the holding portion 1330 are moved in opposite directions. An actuator that exerts an external force is further included in the fixation portion in order for the holding portions 1320 and 1330 to hold the terminal 900 in place.
Next, the processor 830 controls the holding portion in such a manner that the terminal 900 is kept held in place while the autonomous traveling command is being generated (S1250).
More specifically, before the autonomous traveling command is generated, the holding portion is controlled in such a manner that an external force which has a first size is exerted. However, in a case where the autonomous traveling command is generated, the holding portion is controlled in such a manner that an external force which has a second size greater than the first size is exerted.
This is in order to prevent the user from arbitrarily releasing the terminal 900 from the cradle 1310.
On the other hand, the processor 830 selectively generates the autonomous traveling command, according to whether or not the terminal 900 that performs the car mode is held in place by the holding portion.
For example, when the terminal 900 is not held in place by the holding portion, the autonomous traveling command is not generated. Only when the terminal 900 is held in place by the holding portion, the autonomous traveling command is generated.
While the autonomous traveling command is being generated, when the terminal 900 that is held in place by the holding portion is released and thus, is no longer held in place by the holding portion, the processor 830 finishes generating the autonomous traveling command. That is, the vehicle that travels autonomously changes a traveling mode to the manual traveling.
When the terminal 900 is held in place by the holding portion during the manual traveling, the processor 830 limits the generation of the autonomous traveling command in order for the vehicle not to travel autonomously.
The processor 830 controls the proximity communication module 810 in order that the terminal 900 is kept held in place by the holding portion while the autonomous traveling command is being generated. That is, a control command that causes the holding portion to exert a predetermined force on the terminal 100 is transmitted to the holding portion through the proximity communication module 810.
The display unit 251 includes at least one of the following: a driver seat region 251a, a navigation region 251b, and a front right seat region 251e. The driver seat region 251a provides dashboard information to the driver. The navigation region 251b guides a person who rides in the vehicle to a path to a destination. The front right seat region 251e provides various pieces of information to a person who sits on a front right seat.
The cradle 1310 that is described above with reference to
Based on information that is received from the selected terminal 900, the processor 830 calculates the available autonomous traveling time for which the autonomous traveling by the vehicle is possible using the selected terminal 900. The processor 830 controls the proximity communication module 810 in such a manner that time information indicating the calculated time is output to the display unit 251 that is installed in the vehicle 100, or to the terminal 900.
The available autonomous traveling time varies according to at least one of the following: an amount of available data and an amount of available batter power in the terminal 900.
The terminal 900 outputs an execution screen that corresponds to the car mode, to a display 951 of the terminal 900 itself, when the car mode is performed. For example, the available autonomous traveling time (for example, three hours and thirty minutes) is displayed on the execution screen.
On the other hand, the terminal that provides information to the vehicle control device 800 is changed from the first terminal to the second terminal. In this case, the processor 830 recalculates the available autonomous traveling time based on information that is provided by the second terminal, and the time information with the recalculated available autonomous traveling time.
In a case where the pre-defined state where information is not received from the selected terminal is detected while the vehicle 100 is traveling autonomously, the processor 830 may control the proximity communication module 810 in such a manner that alert information which alerts that the autonomous traveling is finished is output to the display unit 251 that is installed in the vehicle 100 or to the display 951 of the terminal 900.
In a state where the terminal 900 is held in place by the holding portion, the terminal 900 performs the car mode, and the vehicle control device 800 generates the autonomous traveling command using information that is received through the terminal 900. Subsequently, the terminal 900 is released from the cradle 1310.
In this case, as illustrated in
Alternatively, as illustrated in
With reference to
The processor 830 generates the autonomous traveling command using the terminal 900.
In a case where the pre-defined state where information is not received from the terminal 900 is detected while the vehicle 100 is traveling autonomously, the processor 830 controls the proximity communication module 810 in such a manner that the alert information which alerts that the autonomous traveling is finished is output to the display unit 251 that is installed in the vehicle 100 or to the display 951 of the terminal 900. The alert information includes the time that it takes for the autonomous traveling to be finished, and the time is counted.
The processor 830 detects that the terminal 900 is placed in the cradle 1310. In a case where the wireless charging unit that supplies power to the terminal 900 is installed in the rear surface of the display unit 251, the user is alerted of a predetermined position in which the efficiency of the wireless charging by the wireless charging unit is higher than a reference. For example, as illustrated in
The predetermined position varies according to a type of the terminal. This is because a shape and a size that are required for the wireless charging vary from one terminal to another. For this reason, based on information that is received from the terminal 900, the processor 830 calculates the predetermined position.
As illustrated in
The display unit 251 includes at least one of the following: the driver seat region 251a, the navigation region 251b, and the front right seat region 251e. The terminal 900 operates in a way that varies according to which one of the regions described above the terminal 900 is placed in.
For example, in a case where the terminal 900 is placed in the navigation region 251b, the car mode is performed, but in a case where the terminal 900 is placed in the front right seat region 251e, the car mode is not performed. This is because, in a case where the terminal 900 is placed in the front right seat region 251e, the person sitting on the front right seat uses the terminal 900 and thus a resource is difficult to manage.
As another example, in a case where the terminal 900 is placed in a region in which the wireless charging is possible, the car mode is performed, but in a case where the terminal 900 is placed in a region in which the wireless charging is impossible, the car mode is not performed. This is because battery power consumption due to data communication causes the terminal to be powered off.
In a case where the terminal 900 is moved from the region in which the wireless charging is possible to the region in which the wireless charging is impossible, the car mode is maintained, but the display 951 of the terminal 900 is powered off. In other words, in a case where the terminal 900 is placed in the region in which the wireless charging is impossible, the car mode is performed, but the display 951 of the terminal 900 is not powered on. This is in order to manage a resource of the terminal 900 within a range where prediction is possible.
