PROBLEM TO BE SOLVED: To easily recognize the change of a detecting state of a control system by a driver according to the state change of the circumference of a vehicle. SOLUTION: A vehicle distance D and a relative speedΔV of a preceding vehicle are detected by a laser radar 10, a control signal is outputted to a servo motor 4 in response to the detected values D,ΔV, and a target reaction force Fm is added to an accelerator pedal 1. When the values D,ΔF are abruptly changed, a state change detector 12 detects the state change in the circumference of the vehicle, and when the state change is detected, the change is added to the target reaction force Fm, and an additional pulseΔFm is added by a predetermined timeΔt. Thus, the reaction force operating at the pedal 1 is abruptly increased, and the driver can recognize the change of the detected state. COPYRIGHT: (C)2003,JPO
