ABSTRACT:
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..!.
A movement control system for motor vehicle (17) comprising controller (3) receiving reference signal (2) from movement control device (1) and energizing brake actuator (6), wherein the motor vehicle is equipped with anti-lock braking (16). In one embodiment signal (2) calls for maximum engine speed at one end of its range and maximum braking at the other end of its range. In another embodiment, signal (2) calls for maximum acceleration at one end of its range and maximum deceleration at the other end of its range, wherein controller (3) calculates the rate of change of the vehicle speed signal (4) which is insensitive to the vehicle's direction, and energizes either throttle actuator (5) or brake actuator (6) until controller's calculated rate of change of speed compares favorably with reference signal (2). Cruise control compares specifically displayed cruise signal (8) with vehicle speed signal (4). Acceleration control to cruise speed uses reference signal (9). Reference signal (13) from cruise start calls for zero acceleration.
