Travel plan information distribution system

A travel plan information distribution system, comprising:

• a wireless communicator that carries out inter-vehicle communication with a peripheral vehicle;
• at least one processor configured to:
• acquire positional information and frontal road shape information of an own vehicle;
• acquire sensor data from a vehicle-mounted sensor group;
• compile travel plan information based on the positional information, the frontal road shape, and the sensor data;
• supply the travel plan information to a display;
• when a change is made to a scheduled driving operation with a specific starting time in the travel plan information, and the specific starting time falls within a predetermined time from a current time, control a light of the own vehicle to notify the peripheral vehicle about the change in the travel plan information prior to the specific starting time, and controls the wireless communicator to transmit the change in the travel plan information to the peripheral vehicle at a transmission cycle shorter than a normal transmission cycle;
• and
• when the change is made to the scheduled driving operation with the specific starting time in the travel plan information, and the specific starting time falls outside the predetermined time from the current time, control the wireless communicator to transmit the change in the travel plan information to the peripheral vehicle at the normal transmission cycle.

A travel plan information distribution system, comprising:

• a wireless communicator that carries out inter-vehicle communication with a peripheral vehicle;
• at least one processor configured to:
• acquire positional information and frontal road shape information of an own vehicle;
• acquire sensor data output from a vehicle-mounted sensor group;
• compile travel plan information based on the positional information, the frontal road shape information, and the sensor data;
• supply the travel plan information to a display;
• wherein the travel plan information includes scheduled travel path information that represents a path along which the own vehicle is to move, and travel plan category information including a lane change based on the scheduled travel path information,
• when a change is made to a scheduled driving operation with a specific starting time in the travel plan information, and the specific starting time falls within a predetermined time from a current time, control a light of the own vehicle to notify the peripheral vehicle about the change in the travel plan information prior to the specific starting time,
• when the change is made to the scheduled driving operation with the specific starting time in the travel plan information, and the specific starting time falls outside the predetermined time from the current time, control the wireless communicator to transmit the change in the travel plan information to the peripheral vehicle at a normal transmission cycle, and
• when the scheduled driving operation is for conducting the lane change in the travel plan information.
