  • Motor vehicle movement control
    Patent number: 5125485
    Abstract: A movement control system for a motor vehicle comprising a movement control device, an acceleration or deceleration signal and a vehicle speed reference signal insensitive to the vehicles' direction are sent to a controller. The system also includes a throttle actuator, brake actuator and anti-lock braking. The controller which receives the acceleration or deceleration signal and vehicle speed reference signal calculates the rate of change of vehicle speed and energizes either the throttle actuator or brake actuator so that the calculated rate of change of speed compares favorably to the reference signal from the movement control device. A cruise control sends a reference speed signal to the controller which compares it to the vehicle speed signal and energizes either the throttle actuator or brake actuator so that the two signals favorably compare, thus controlling the vehicle speed while in the cruise control mode.
