Automatic deceleration control system, vehicle-to-obstacle distance control system, and system program storage medium for vehicle

摘要

Automatic acceleration/deceleration control for an automotive vehicle is provided which may be used in an automatic deceleration system and a vehicle-to-obstacle distance control system. The automatic acceleration/deceleration control determines a brake pressure control command when decelerating the vehicle based on a deceleration difference between a target deceleration and an actual deceleration of the vehicle and adjusts the brake pressure acting on a wheel of the vehicle in response to the brake pressure control command to decelerate the vehicle so that the actual deceleration agrees with the target deceleration. The automatic acceleration/deceleration control further corrects the brake pressure control command by modifying the deceleration difference for compensating for a time delay between output of the brake pressure control command and a time when the vehicle is actually decelerated.
