Vehicle communication system and vehicle control device

A control method executed by processors of an electronic control unit (ECU) mounted in a vehicle, the vehicle including a GPS receiver configured to receive signals from GPS satellites, and an actuator including a throttle actuator, a brake actuator, and a steering actuator, the control method comprising:

• recognizing a position of the vehicle on a map based on the signals received by the GPS receiver;
• acquiring section information on a communication established section and a communication interrupted section via communication with a communication server configured to communicate with a plurality of communication vehicles, the communication vehicles being vehicles configured to communicate with the communication server, the communication established section and the communication interrupted section being set on the map by the communication server based on a status of communication with the communication vehicles;
• determining in which section, either the communication established section or the communication interrupted section, the vehicle is traveling, based on the position of the vehicle on the map and the section information;
• performing vehicle control of the vehicle using the actuator, in such a way that system driven control of the vehicle is performed, when the vehicle travels in the determined communication established section;
• performing driver driven control of the vehicle when the vehicle travels in the determined communication interrupted section;
• and
• performing the system driven control of the vehicle based on road condition information acquired from the communication server, when the vehicle travels in the determined communication established section.

A non-transitory storage medium storing instructions that are executable by processors of an electronic control unit (ECU) mounted in a vehicle and cause the processors to perform functions, the vehicle including a GPS receiver configured to receive signals from GPS satellites, and an actuator including a throttle actuator, a brake actuator, and a steering actuator, the functions comprising:

• recognizing a position of the vehicle on a map based on the signals received by the GPS receiver;
• acquiring section information on a communication established section and a communication interrupted section via communication with a communication server configured to communicate with a plurality of communication vehicles, the communication vehicles being vehicles configured to communicate with the communication server, the communication established section and the communication interrupted section being set on the map by the communication server based on a status of communication with the communication vehicles;
• determining in which section, either the communication established section or the communication interrupted section, the vehicle is traveling, based on the position of the vehicle on the map and the section information;
• performing vehicle control of the vehicle using the actuator, in such a way that system driven control of the vehicle is performed, when the vehicle travels in the determined communication established section;
• performing driver driven control of the vehicle when the vehicle travels in the determined communication interrupted section;
• and
• performing the system driven control of the vehicle based on road condition information acquired from the communication server, when the vehicle travels in the determined communication established section.
