Abstract:
1. A system for controlling deceleration of a vehicle having a multiple cylinder internal combustion engine, each cylinder having at least one electronically actuated gas exchange valve, the system comprising: a microprocessor-based controller; an accelerator pedal mounted in a passenger compartment of the vehicle and including a position sensor in communication with the controller; a speed sensor in communication with the controller for determining vehicle speed based on rotational speed of at least one vehicle component; and an engine driven electrically controllable vehicle accessory in communication with the controller; wherein the controller determines a desired vehicle deceleration when the speed sensor indicates the vehicle is moving and the accelerator position sensor indicates the accelerator pedal has moved to a released position, the controller further controlling the at least one gas exchange valve and electrically controllable vehicle accessory such that measured vehicle deceleration approaches the desired vehicle deceleration.
