ABSTRACT:
A novel vehicle deceleration control device for ensuring a proper distance between a vehicle and a preceding vehicle, etc., equipped on a vehicle, automatically decelerates the vehicle by controlling braking force based on a target deceleration, calculated based on a relative distance and a relative speed between the vehicle and its preceding vehicle, etc., when automatic deceleration is required. The inventive device, however, will decelerate the own vehicle based on a maximum allowable deceleration when the magnitude of the target deceleration is larger than the magnitude of the maximum allowable deceleration, restricting the vehicle deceleration. The maximum allowable deceleration is determined based on the vehicle speed of the own vehicle when a predetermined condition is satisfied, and maintained at a constant or within a predetermined range, thereby enabling a driver to judge the necessity of braking operation by himself during restricting the vehicle deceleration more easily than ever.
