Vehicle control system, vehicle control method, and vehicle control server

A vehicle control method to be executed by a computer for controlling wireless communication in a vehicle having functionality of wide-area wireless communication through a public line and narrow-area wireless communication that performs narrow-area wireless communication for directly communicating with a mobile terminal, the vehicle control method comprising:

• a vehicle positional information obtaining step of obtaining vehicle positional information indicating a current position of the vehicle;
• a user terminal positional information obtaining step of obtaining user terminal positional information indicating a current position of a user terminal, the user terminal having functionality of the wide-area wireless communication and the narrow-area wireless communication and being the mobile terminal to be used by a user of the vehicle;
• a relative distance recognizing step of recognizing a relative distance between the vehicle and the user terminal based on the vehicle positional information and the user terminal positional information;
• and
• a narrow-area wireless communication control step of controlling implementation of the narrow-area wireless communication in the vehicle and, if the relative distance is longer than or equal to a determination distance set based on a communicable distance of the narrow-area wireless communication, restricting implementation of the narrow-area wireless communication in the vehicle.

A vehicle control method to be executed by a terminal processor included in a user terminal for controlling wireless communication in a vehicle having functionality of wide-area wireless communication through a public line and narrow-area wireless communication that performs narrow-area wireless communication for directly communicating with a mobile terminal, the user terminal being the mobile terminal to be used by a user of the vehicle, the vehicle control method comprising:

• a vehicle positional information obtaining step of obtaining vehicle positional information indicating a current position of the vehicle by receiving the vehicle positional information from the vehicle through the wide-area wireless communication or the narrow-area wireless communication;
• a user terminal positional information obtaining step of obtaining user terminal positional information indicating a current position of the user terminal based on a terminal position detection signal by a terminal position sensor provided in the user terminal;
• a relative distance recognizing step of recognizing a relative distance between the vehicle and the user terminal based on the vehicle positional information and the user terminal positional information;
• and
• a narrow-area wireless communication control step of controlling implementation of the narrow-area wireless communication in the vehicle, and, if the relative distance is longer than or equal to a determination distance set based on a communicable distance of the narrow-area wireless communication, restricting implementation of the narrow-area wireless communication in the vehicle by transmitting narrow-area wireless communication restriction information that instructs to restrict the narrow-area wireless communication to the vehicle.

A vehicle control server that performs wide-area wireless communication between a vehicle having communication functionality by the wide-area wireless communication through a public communication and narrow-area wireless communication that performs narrow-area wireless communication for directly communicating with a mobile terminal and a user terminal having communication functionality by the wide-area wireless communication and the narrow-area wireless communication, the user terminal being the mobile terminal to be used by a user of the vehicle, the vehicle control server comprising:

• a vehicle positional information obtaining unit obtaining vehicle positional information indicating a current position of the vehicle from the vehicle through the wide-area wireless communication;
• a user terminal positional information obtaining unit obtaining user terminal positional information indicating a current position of the user terminal from the user terminal through the wide-area wireless communication;
• a relative distance recognizing unit recognizing a relative distance between the vehicle and the user terminal based on the vehicle positional information and the user terminal positional information;
• and
• a narrow-area wireless communication control unit controlling implementation of the narrow-area wireless communication in the vehicle and, if the relative distance is longer than or equal to a determination distance set based on a communicable distance of the narrow-area wireless communication, transmitting narrow-area wireless communication restriction information that instructs to restrict implementation of the narrow-area wireless communication in the vehicle to the vehicle through the wide-area wireless communication.
