Abstract:
In an autonomous traveling vehicle having acceleration/deceleration actuators, a vehicle control system comprising:vehicle position detection means for detecting the position of a vehicle on the basis of information received from information sources disposed on a road;control plan processing means for creating a control plan formed of correlation data of speed and distance, on the basis of at least one of information received from a preceding vehicle and information received from information transmission means disposed on or near the road;deviation calculation means for calculating at least one of a distance deviation and a speed deviation at an anticipated arrival point of the vehicle after a predetermined time period, on the basis of the control plan and the vehicle position;vehicle-speed control means for controlling the accelerating/decelerating actuators on the basis of at least one of the distance deviation and the speed deviation; andcorrection means for correcting at least one of the distance deviation and the speed deviation in order to compensate for any deviation due to a gradient of the road, on the basis of information about the road gradient as received from the information transmission means.
