摘要

A vehicle-mounted device includes a data collection device that collects sensor data from a vehicle sensor, a data transmission device that sends the sensor data to a server, a data reception device that receives data on an outside vehicle status, and an inside-end-side vehicle / outside-vehicle cooperation device that responds to the reception of the data on the outside vehicle status cooperates with a device outside the vehicle and controls an operation inside the vehicle. The server includes a map generation device that maintains a traffic status overview map based on the received sensor data, a vehicle selection device that selects a vehicle, which is used to send optimal sensor data for maintaining the traffic status overview map in terms of a line status between vehicle-mounted devices that are present within a specific area, and a transmission permission / prohibition signal transmission device that transmits an instruction to permit transmission of sensor data to the vehicle. In response to receiving an instruction, the inside vehicle / outside vehicle cooperation device controls an in-vehicle functional unit according to the instruction.
