Abstract:
An automatic deceleration control method for a vehicle comprising:determining a brake pressure control command when decelerating the vehicle based on a deceleration difference between a target deceleration value determined according to driving conditions of the vehicle and an actual measured deceleration value of the vehicle, the brake pressure control command causing the actual deceleration value of the vehicle to change towards the target deceleration;correcting said brake pressure control command by modifying the deceleration difference based on advancing a phase of the target deceleration value to compensate for a time delay between output of the brake pressure control command and actual deceleration of the vehicle in response to the brake pressure control command; andadjusting brake pressure acting on a wheel of the vehicle in response to said corrected brake pressure control command to decelerate the vehicle.
