TRAVELING SAFETY DEVICE FOR VEHICLE

摘要

PROBLEM TO BE SOLVED: To reduce a braking force while preventing a temporary increase in the breaking force, when a driver's voluntary contact avoiding operation is detected and a brake release command for releasing an automatic brake is outputted in a traveling safety device for a vehicle detecting a relative distance and a relative speed of an object such as a preceding car by a radar device and actuating an automatic brake device when there is a possibility of touching the own ear with the object. SOLUTION: A target deceleration (braking force command value) is raised to a target value G at a time T1 and a brake release command is outputted at a time T8 before the practical deceleration reaching the target value G, the target deceleration is dashingly reduced from the target value G to a prescribed value G1 and gradually reduced from the prescribed value G1 to 0. The prescribed value G1 is the practical deceleration of the own car when the brake release command is outputted.
