Description

  The present invention relates to a vehicle operation key assignment system and a vehicle operation key assignment program.

  A technique for delivering an electronic key capable of locking / unlocking a door lock of a vehicle when a predetermined operation is performed between the electronic key delivering side and the receiving side is known (patent) Reference 1).

Japanese Patent Laid-Open No. 7-9924

However, when an electronic key is transferred to a user who has performed a predetermined operation as in Patent Document 1, there is a problem that an electronic key is given to an unexpected user. That is, since an electronic key is given to a user who performs a predetermined operation, there is a problem that an electronic key is given to a user who does not get on the vehicle.
The present invention has been made in view of the above problems, and an object thereof is to provide a technique capable of reducing the possibility of giving an electronic operation key of a vehicle to an unexpected user.

  In order to achieve the above object, a vehicle operation key assigning system according to the present invention is a vehicle operation key assigning system provided in a vehicle capable of running control when a master key is authenticated. A terminal detection unit that detects a target terminal that is a terminal that has existed in the vehicle during a certain travel period, and a key grant unit that grants an electronic operation key for operating the vehicle to the target terminal.

  In order to achieve the above object, a vehicle operation key assigning program according to the present invention causes a vehicle to run a vehicle operation key assigning system, which is a computer provided in a vehicle capable of running control when a master key is authenticated. It functions as a terminal detection function that detects a target terminal that is a terminal that has been present in the vehicle during a traveling period, and a key grant function that grants an electronic operation key for operating the vehicle to the target terminal.

  In the above configuration, the target terminal that was present in the vehicle during the traveling period is likely to be a terminal owned by the vehicle occupant, and the terminal owned by the user who has accepted the owner of the master key. Is likely. Therefore, the possibility of giving the electronic operation key to an unexpected user can be reduced by giving the vehicle's electronic operation key to the target terminal that has been present in the vehicle during the traveling period. Further, it is possible to reduce the possibility of receiving an electronic operation key illegally by bringing the terminal closer to a stopped vehicle.

It is a block diagram of a vehicle operation key provision system. It is a flowchart of a vehicle operation key provision process.

Here, embodiments of the present invention will be described in the following order.
(1) Configuration of the vehicle operation key assignment system:
(2) Vehicle operation key assignment processing:
(3) Other embodiments:

(1) Configuration of the vehicle operation key assignment system:
FIG. 1 is a block diagram showing a configuration of a vehicle operation key assigning system 10 according to an embodiment of the present invention. The vehicle operation key assigning system 10 is an in-vehicle device mounted on a vehicle. The vehicle operation key assigning system 10 may be a part of a car navigation device. The vehicle operation key assigning system 10 includes a control unit 20, a short-range communication unit 25, and a recording medium 30. The control unit 20 includes a CPU, a RAM, a ROM, and the like, and executes a vehicle operation key assignment program 21 stored in the recording medium 30 or the ROM.

  The short-range communication unit 25 is a wireless communication circuit that performs radio communication using radio waves, and adopts the Bluetooth LE standard as its communication standard (Bluetooth is a registered trademark). The communication distance limit of Bluetooth LE is about 5 m, but the communication distance limit can be switched by switching the communication type defined in the Bluetooth LE standard. The communication type can be switched between “very close” (CLProximityImmediate), “close” (CLProximityNear), and “far” (CLProximityFar) in ascending order of the communication limit distance. In the present embodiment, it is assumed that the communication type is set to “near” so that a circle whose radius is the communication limit distance is in a range substantially corresponding to the passenger's boarding space. That is, by setting the communication type to “near”, the boarding space and the space within the communication limit distance are substantially matched. Note that a communication type may be set such that the greater the boarding space for the passenger, the greater the communication distance limit. The antenna of the short-range communication unit 25 may be provided in the center of the boarding space.

  The recording medium 30 records master key data MK. The master key data MK is data for comparison with the master key data MK received from another terminal by the short-range communication unit 25. When the master key data MK that matches the master key data MK recorded on the recording medium 30 is received from another terminal, it is assumed that the master key data MK received from the other terminal is normal, and the other terminal is the master key data MK. It is authenticated as a terminal. When the master terminal is authenticated, traveling control and additional control that is additional vehicle control other than traveling control are permitted. Here, the traveling control includes at least control for accelerating and decelerating the vehicle and control for steering the vehicle. The travel control may be manual operation control performed in response to an operation on a vehicle operation unit (a handle, an accelerator pedal, a brake pedal, a clutch pedal, a shift lever, etc.) (not shown), or automatic operation control. May be. The additional control includes at least an operation of unlocking / locking the door lock of the vehicle, and may include an operation of opening / closing a vehicle window, an operation of an air conditioner, and the like.

  The recording medium 30 records additional key data AK. The additional key data AK is also data for comparison with data received from other terminals by the short-range communication unit 25. When the additional key data AK that matches the additional key data AK recorded on the recording medium 30 is received from another terminal, the additional key data AK received from the other terminal is normal and the other terminal is added. It is authenticated as a terminal. Here, an operation for performing additional control is permitted in the master terminal or the additional terminal. That is, the additional control can be performed by operating another terminal that records the master key data MK and the additional key data AK. Although an operation for performing the traveling control may be permitted at the master terminal, the operation for performing the traveling control in the present embodiment can be performed only on the operation unit of the vehicle (not shown). The other terminal may be a terminal that can be carried by an occupant, but is assumed to be a smartphone in the present embodiment.

  The vehicle includes a GPS receiver 41, a vehicle speed sensor 42, a gyro sensor 43, and a vehicle control ECU (Electronic Control Unit) 44. The GPS receiver 41 receives radio waves from GPS satellites and outputs a signal for calculating the position of the vehicle via an interface (not shown). The vehicle speed sensor 42 outputs a signal corresponding to the rotational speed of the wheels provided in the vehicle. The control unit 20 acquires the vehicle speed based on a signal from the vehicle speed sensor 42. The gyro sensor 43 detects angular acceleration about turning in the horizontal plane of the vehicle, and outputs a signal corresponding to the direction of the vehicle. The control unit 20 acquires the traveling direction of the vehicle based on the signal from the gyro sensor 43. The control unit 20 acquires the motion state (position, speed, acceleration) of the vehicle based on the output signals of the GPS receiving unit 41, the vehicle speed sensor 42, and the gyro sensor 43.

  The vehicle control ECU 44 is a computer for controlling each controlled device of the vehicle (not shown). Controlled devices include power units (engines, motors, etc.), steering devices, braking devices, transmissions, door lock devices, power window devices, air conditioners, and the like.

  The vehicle operation key assignment program 21 includes an authentication module 21a, a terminal detection module 21b, and a key assignment module 21c. The authentication module 21a, the terminal detection module 21b, and the key assignment module 21c are program modules that cause the control unit 20 as a computer to function as an authentication unit, a terminal detection unit, and a key assignment unit, respectively.

  With the function of the authentication module 21a, the control unit 20 authenticates another terminal to which a normal master key is assigned as a master terminal. That is, the control unit 20 determines whether or not the other terminal has the normal master key data MK by communicating with another terminal such as the smartphone 50a, and stores the normal master key data MK. If so, the other terminal is authenticated as the master terminal. The normal master key data MK is master key data MK that matches the master key data MK of the recording medium 30.

  In the example of FIG. 1, the smartphone 50a is authenticated as the master terminal. The smartphone 50a can be authenticated by transmitting the master key data MK to the vehicle operation key grant system 10. This master key data MK is transmitted to the vehicle operation key assigning system 10 via the short-range communication unit 25. Therefore, the smartphone 50a is authenticated in a state where the smartphone 50a that records the normal master key data MK exists within the communication distance limit (in the vehicle) of the short-range communication unit 25.

  When the master terminal is authenticated, the control unit 20 periodically communicates with the master terminal via the short-range communication unit 25 by the function of the authentication module 21a, and in the master authentication period, which is a period during which communication with the master terminal is possible. The vehicle control ECU 44 is controlled so that the vehicle travel can be controlled. That is, in the master authentication period in which the user carrying the master terminal exists within the communication distance limit (in the vehicle) of the short-range communication unit 25, the user can drive the vehicle by operating the operation unit of the vehicle (not shown). It becomes. Note that the master authentication period is not necessarily limited to the period in which communication with the master terminal is possible, and may be a period obtained by adding a subsequent fixed period (for example, 10 minutes) to the period in which communication with the master terminal is possible. Further, the master authentication period may be a period until the engine started in a state where it can communicate with the master terminal is stopped, or the main power source of the electric vehicle which is turned on in a state where it can communicate with the master terminal is It may be a period until it becomes OFF.

  Further, the control unit 20 uses the function of the authentication module 21a to perform additional vehicle control (such as locking / unlocking the door lock) in response to an operation on the operation unit (not shown) during the master authentication period in which communication with the master terminal is possible. The vehicle control ECU 44 is controlled to carry out. Further, when receiving a signal for instructing additional control from the master terminal, the control unit 20 controls the vehicle control ECU 44 to perform additional control of the vehicle according to the signal by the function of the authentication module 21a. Specifically, the master terminal accepts an operation for instructing additional control. When the operation is accepted, the master terminal transmits master key data MK together with a signal instructing additional control to the vehicle operation key assigning system 10. To do. When the normal master key data MK is received together with a signal for instructing additional control, the control unit 20 controls the vehicle control ECU 44 to perform additional control of the vehicle according to the signal by the function of the authentication module 21a. Thereby, in the master authentication period, the user carrying the master terminal can instruct additional control by operating the operation unit or the master terminal of the vehicle (not shown).

  The master key data MK may be provided to the master terminal by the vehicle operation key assigning system 10 by performing a predetermined authentication operation, for example, or a device other than the vehicle operation key assigning system 10 (for example, a vehicle manufacturer) Or a computer such as a dealer) provided to the master terminal.

  Furthermore, by the function of the authentication module 21a, the control unit 20 authenticates another terminal to which a normal additional key is assigned as an additional terminal in the master authentication period. That is, the control unit 20 determines whether or not the other terminal has recorded the normal additional key data AK by communicating with the other terminal such as the smartphone 50b, and stores the normal additional key data AK. If it is recorded, the other terminal is authenticated as an additional terminal. However, the control unit 20 authenticates the additional terminal only during the master authentication period, and does not authenticate the additional terminal during the period when the master terminal is not authenticated. The normal additional key data AK is additional key data AK that matches the additional key data AK of the recording medium 30.

  In the example of FIG. 1, the smartphone 50b can be authenticated as an additional terminal in the master authentication period in which the smartphone 50a is authenticated as a master terminal. The smartphone 50b can be authenticated by transmitting the additional key data AK to the vehicle operation key grant system 10. This additional key data AK is transmitted to the vehicle operation key assigning system 10 via the short-range communication unit 25. Therefore, the smartphone 50b is authenticated as an additional terminal in a state where the smartphone 50b in which the additional key data AK is recorded is present within the communication distance limit (in the vehicle) of the short-range communication unit 25.

  Specifically, the additional terminal receives an operation for instructing additional control, and when the operation is received, transmits additional key data AK together with a signal instructing additional control to the vehicle operation key grant system 10. To do. When the control module 20 receives normal additional key data AK together with a signal for instructing additional control by the function of the authentication module 21a, the control unit 20 authenticates the terminal that transmitted the additional key data AK as an additional terminal and In response, the vehicle control ECU 44 is controlled to perform additional control of the vehicle. Thereby, the user who carries an additional terminal can instruct | indicate the additional control of a vehicle by operating an additional terminal in a master authentication period. Further, the additional terminal may request input of a password or the like when instructing additional control.

  With the above configuration, it is possible to control the traveling of the vehicle and to drive the vehicle only during the master authentication period in which the master terminal is authenticated. During this master authentication period, it is possible to instruct additional control of the vehicle (locking / unlocking doors, etc.) from the master terminal. Furthermore, during the master authentication period, it is possible to instruct additional control of a vehicle from an additional terminal to which a normal additional key is assigned. That is, a passenger carrying an additional terminal to which an additional key is assigned can also instruct additional control of the vehicle during a period in which the driver carrying the master terminal to which the master key is assigned can drive the vehicle. ing.

  The additional key is given when the vehicle operation key giving system 10 transmits normal additional key data AK to the additional terminal. Hereinafter, the structure for the vehicle operation key provision system 10 to provide an additional key is demonstrated in detail.

  The terminal detection module 21b is a program module that causes the control unit 20 to realize a function of detecting a target terminal that is a terminal that has existed in the vehicle during the traveling period in which the vehicle is traveling. That is, if the function of the terminal detection module 21b allows the control unit 20 to detect a target terminal such as the smartphone 50b that is present in the vehicle during the traveling period of the vehicle, additional key data AK is added to the target terminal. By transmitting, an additional key is given to the target terminal. Thereby, the user carrying the target terminal can instruct additional control of the vehicle by operating the target terminal.

  Specifically, by the function of the terminal detection module 21b, the control unit 20 detects, as a target terminal, a terminal whose distance from the vehicle during the traveling period is equal to or less than a reference distance. In the present embodiment, the function of the terminal detection module 21b allows the control unit 20 to select a terminal capable of short-range communication with the short-range communication unit 25 as a communication unit provided in the vehicle, and the distance from the vehicle is a reference distance. Consider a terminal that is: That is, the reference distance of this embodiment is a communication distance limit of the short-range communication unit 25.

  Furthermore, by the function of the terminal detection module 21b, the control unit 20 detects, as a target terminal, a terminal in which the distance from the vehicle during the traveling period is equal to or less than a reference distance. That is, the control unit 20 gives an additional key to a terminal in which a state in which communication via the short-range communication unit 25 is possible continues for a threshold value (for example, 1 minute) or more during the traveling period. For example, the control unit 20 tries to communicate with the terminal via the short-range communication unit 25 every predetermined time period, and the number of times of successful communication with the terminal is a certain number of times (= threshold / time). If it is equal to or greater than (period), an additional key is assigned to the terminal.

  Here, the traveling period is a period in which the vehicle speed is equal to or higher than a reference value. The control unit 20 acquires the vehicle speed based on the output signal from the vehicle speed sensor 42 by the function of the terminal detection module 21b, and sets a period in which the vehicle speed is equal to or higher than a reference value (for example, 10 km / h) as a travel period. Then, the control unit 20 detects, as a target terminal, a terminal in which a state in which the distance from the vehicle is equal to or less than the reference distance during the traveling period continues for a threshold value or more. Accordingly, if the vehicle stops and the traveling period ends before the state where the distance between the vehicle and the terminal is equal to or less than the reference distance continues for the threshold value or more, the additional key is not given to the terminal.

  The key assigning module 21c is a program module that causes the control unit 20 to realize a function of assigning an electronic operation key (additional key) for operating the vehicle to the target terminal (additional terminal). Specifically, the control unit 20 generates the additional key data AK when the target terminal is detected by the function of the key assignment module 21c, records the additional key data AK on the recording medium 30 for comparison, and Send to the target terminal. The timing for adding the additional key may be after the target terminal is detected, and may not necessarily be the timing at which the target terminal is detected. For example, the timing for giving the additional key may be the end timing of the travel period in which the target terminal is detected, or the end timing of the master authentication period. Furthermore, the timing to give the additional key may be a timing at which an operation such as inputting a password is accepted from the target terminal or the master terminal after the target terminal is detected.

  In the present embodiment described above, the target terminal that was present in the vehicle during the traveling period is likely to be a terminal owned by the vehicle occupant, and the user who has accepted the owner of the master key is on board Is likely a terminal owned by. Therefore, the possibility of giving the electronic operation key to an unexpected user can be reduced by giving the vehicle's electronic operation key to the target terminal that has been present in the vehicle during the traveling period. Further, it is possible to reduce the possibility of receiving an electronic operation key illegally by bringing the terminal closer to a stopped vehicle.

  If the distance from the vehicle during the row period is equal to or less than the reference distance, it can be considered that the terminal moves with the vehicle and exists in the vehicle. Therefore, the control part 20 can detect the terminal whose distance with the vehicle in a driving | running | working period is below a reference distance as an object terminal. The control unit 20 regards a terminal capable of short-range communication with the short-range communication unit 25 as a communication unit provided in the vehicle as a terminal whose distance from the vehicle is equal to or less than a reference distance. The distance sensor for measuring the distance can be omitted.

  The control unit 20 detects, as a target terminal, a terminal in which a state where the distance from the vehicle in the traveling period is equal to or less than the reference distance continues for a threshold value or more. If the distance from the vehicle is kept below the reference distance during the traveling period in which the vehicle is moving, it can be said that the terminal is very likely to be present in the vehicle. Therefore, the possibility of giving an electronic operation key to a terminal that has only temporarily approached the vehicle can be reduced. In addition, by setting the period of travel at a relatively high vehicle speed as the travel period, an additional key is given to a terminal carried by a pedestrian who happened to be near the vehicle while the vehicle was stopped or a terminal in another vehicle The possibility of doing so can be reduced.

(2) Vehicle operation key assignment processing:
Next, the vehicle operation key provision process executed by the function of the vehicle operation key provision program 21 will be described. FIG. 2 is a flowchart of the vehicle operation key assigning process. First, the control unit 20 determines whether or not the master key is being authenticated by the function of the authentication module 21a (step S100). That is, the control unit 20 determines whether or not it is a master authentication period that is a period during which communication with the master terminal that has transmitted the normal master key data MK is possible. The master authentication period is a period during which vehicle travel control is possible, and commands additional vehicle control (locking / unlocking of door locks, etc.) not only from the operation unit of the vehicle (not shown) but also from the master terminal. Is a period in which

  When it is not determined that the master key is being authenticated (step S100: N), the control unit 20 returns to step S100. That is, the control unit 20 waits until the master key is authenticated. By doing in this way, an additional key can be given only during the master authentication period when the user who carries the master terminal to which the master key was given is on board. That is, an additional key can be given to a terminal carried by another user who is on the vehicle together with a user carrying the master terminal.

  If it is determined that the master key is being authenticated (step S100: Y), the function of the terminal detection module 21b causes the control unit 20 to determine whether or not it is during the travel period (step S110). That is, the control unit 20 determines whether or not the current vehicle speed is equal to or higher than a reference value (for example, 10 km).

  If it is not determined that the vehicle is traveling (step S110: N), the control unit 20 returns to step S100 by the function of the terminal detection module 21b. That is, the control unit 20 waits until the traveling period is reached during the master authentication period.

  On the other hand, when it determines with it being during a driving | running | working period (step S110: Y), the control part 20 measures the continuation period of near field communication by the function of the terminal detection module 21b (step S120). That is, the control unit 20 detects a terminal that can communicate via the short-range communication unit 25 and measures a period during which the terminal can continuously communicate. When a plurality of communicable terminals are detected via the short-range communication unit 25, the duration of short-distance communication may be measured for each of the communicable terminals.

  Next, by the function of the terminal detection module 21b, the control unit 20 determines whether or not the duration of the near field communication is equal to or greater than a threshold (for example, 1 minute) (step S130). When it is not determined that the duration of the near field communication is greater than or equal to the threshold (step S130: N), the control unit 20 returns to step S110. That is, the control unit 20 waits until the duration of the short-range communication becomes equal to or greater than the threshold during the traveling period. Steps S <b> 110 to S <b> 130 are loop processing, and each time the processing is repeated in step S <b> 120, the duration of short-distance communication is added by the execution period of step S <b> 120. And it will transfer to step S140 in the stage where the terminal whose duration of near field communication became more than a threshold is detected.

  If it is determined that the duration of the near field communication is greater than or equal to the threshold (step S130: Y), the control unit 20 assigns an additional key by the function of the terminal detection module 21b (step S140). That is, when the target terminal is detected, the control unit 20 generates additional key data AK, records the additional key data AK on the recording medium 30 for comparison, and transmits it to the target terminal. As a result, the target terminal records the additional key data AK, and the target terminal becomes an additional terminal that can be instructed to perform additional control.

(3) Other embodiments:
In the embodiment, a terminal whose distance from the vehicle during the traveling period is equal to or less than the reference distance is detected as a target terminal. However, as a method for determining whether the terminal exists in the vehicle, another method is adopted. Also good. For example, a terminal captured by a camera that captures the inside of the vehicle may be detected as a terminal existing in the vehicle, or a terminal that detects an environmental sound (engine sound, audio sound, etc.) in the vehicle exists in the vehicle. It may be detected as a terminal. In addition, as a technique for detecting a terminal whose distance from the vehicle during the traveling period is equal to or less than the reference distance, a technique that does not use short-range communication may be employed. For example, a terminal whose distance from the vehicle is a reference distance or less may be detected by a distance meter using a laser or radio wave.

  The vehicle operation key assigning system 10 does not necessarily have to be realized by the vehicle-mounted device, and may be realized by the smartphone 50a to which the master key is assigned in advance. Furthermore, the vehicle operation key assigning system 10 only needs to be able to determine whether or not the terminal exists in the vehicle, and does not necessarily exist in the vehicle. For example, the vehicle operation key assigning system 10 may be a server that can acquire the position of the terminal and the position of the vehicle by communication. If the position of the terminal and the position of the vehicle can be acquired, it can be determined whether or not the terminal is present in the vehicle even if the server is not present in the vehicle.

  In the present invention, the master key may be an electronic key, a biometric authentication key (fingerprint, iris, vein, etc.), or a physical key such as a cylinder lock. The key assigning unit may provide the electronic operation key in a state where the master key is recognized, and the type of the master key is not particularly limited. The travel control may be enabled by operating the power unit of the vehicle so that the vehicle can travel. The vehicle operation key assigning system may be provided in the vehicle. For example, the vehicle operation key assigning system may be incorporated in various devices (for example, a control ECU) constituting a part of the vehicle, or may be a device that can be installed in the vehicle as an optional device, It may be a portable terminal such as a smartphone brought into the network. The vehicle operation key assigning system may be a server that can communicate with the vehicle. That is, the vehicle operation key assigning system may remotely assign the electronic operation key to a terminal that has existed in the vehicle.

  The terminal detection unit only needs to be able to detect the target terminal, and may detect the target terminal by comparing various types of motion information such as position, speed, and acceleration between the vehicle and the terminal. That is, the terminal detection unit may determine that the terminal has moved with the vehicle in the vehicle when the various pieces of exercise information are more than a threshold. Further, the terminal detection unit may detect a physical contact state between the terminal and the vehicle, and detect a terminal that has been kept in contact during the traveling period as a target terminal. The terminal may be any device that can be provided with an electronic operation key, and includes a recording medium that records at least data of the electronic operation key, and an output device that can output the data to the vehicle during operation. If it is. The terminal may be any terminal that is brought into the vehicle by a vehicle occupant, and may be a mobile terminal such as a smartphone.

  The method by which the key assigning unit assigns the electronic operation key is not particularly limited, and various known methods can be used. The key assigning unit transmits electronic operation key data to all terminals existing in the vehicle in advance, and activates the electronic operation key for the terminal determined to be the target terminal during the traveling period. Data to be transmitted may be transmitted. The electronic operation key is desirably encrypted, but it is not necessarily encrypted. Further, the content of the vehicle operation that can be performed by the given electronic operation key may be more limited than the content of the operation that can be performed by the master key, or the same as the content of the operation that can be performed by the master key. There may be.

  Further, the terminal detection unit may detect a terminal whose distance from the vehicle during the traveling period is a reference distance or less as a target terminal. That is, if the distance from the vehicle during the traveling period is equal to or less than the reference distance, it can be considered that the terminal moves with the vehicle and exists in the vehicle.

  Furthermore, the terminal detection unit regards a terminal capable of short-range communication with a communication unit provided in the vehicle as a terminal having a distance from the vehicle equal to or less than a reference distance. Thereby, the distance sensor which measures the distance between a vehicle and a terminal can be omitted. Here, short-range communication may be, for example, wireless communication having a communication distance limit smaller than a certain distance, or wired communication. The wireless communication may be a wireless local area network (LAN), Bluetooth or Bluetooth LE, NFC (Near Field Communication), or infrared communication. Further, whether or not the terminal exists in the vehicle may be determined based on the radio wave intensity received by the communication unit provided in the vehicle, regardless of whether short-range communication is possible. Providing a place for placing the terminal around the antenna for near field communication (within the communication distance limit) and prompting the user to place the terminal for which an additional key is desired to be placed on the place. Also good.

  Further, the terminal detection unit may detect, as a target terminal, a terminal in which a state where the distance from the vehicle during the traveling period is equal to or less than a reference distance continues for a threshold value or more. If the distance from the vehicle is kept below the reference distance during the traveling period in which the vehicle is moving, it can be said that the terminal is very likely to be present in the vehicle. Therefore, it is erroneously determined that a terminal that has only temporarily approached the vehicle is present in the vehicle, and the possibility of giving an electronic operation key can be reduced. The threshold value may be a constant value or a variable value. For example, a smaller threshold may be set as the communication distance (radio wave intensity or the like) in short-range communication is larger.

  Further, the traveling period may be a period in which the vehicle speed is equal to or higher than a reference value. Possibility of giving electronic operation keys to terminals carried by pedestrians who happened to be in the vicinity while the vehicle was stopped or terminals in other vehicles by setting the period during which the vehicle traveled at a relatively high vehicle speed as the traveling period Can be reduced. In a state where the speed of the vehicle is high, a terminal carried by a pedestrian is less likely to keep the distance from the vehicle below the reference distance. In addition, when the speed of the vehicle is high, the distance between the vehicles becomes large, so that the possibility of keeping the distance from the vehicle below the reference distance is low even for terminals in other vehicles traveling on the same road in the same direction. . Furthermore, the traveling period may be a period in which a motion state such as the speed, acceleration, or traveling direction of the vehicle has changed. In other words, if the distance from the vehicle is kept below the reference distance even if the movement state of the vehicle changes, it can be determined that the terminal is moving following the vehicle and the terminal is considered to exist in the vehicle. be able to. For example, the traveling period may be a period including before and after the time of turning right or left at the intersection. Furthermore, the travel period may be a period during which a road having a specific shape is traveled. For example, the traveling period may be a period of traveling on a one-lane road. Thereby, possibility that another vehicle will run in parallel can be reduced, and possibility that an electronic operation key will be given to a terminal in another vehicle can be reduced.

  Furthermore, as in the present invention, a technique for giving an electronic operation key to a terminal existing in a vehicle can be applied as a program or a method. In addition, the system, program, and method as described above may be realized as a single device, or may be realized using components shared with each part of the vehicle, and include various aspects. It is a waste. For example, it is possible to provide a navigation system, a vehicle operation key assignment system, a method, and a program that include the above devices. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the apparatus. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.
