CRUISE CONTROL SYSTEM

Print

The cruise control system maintains the vehicle speed at a setting selected by the driver by mean of mechanical, electrical, and vacuum operated devices.

The cruise control unit receives command signals from the cruise control main switch and the cruise control set/resume switch. The control unit also receives information about operating conditions from the brake switch, the distributor, speed sensor, the clutch switch (with manual transaxle), or the shift lever position switch (with automatic transaxle). The cruise control unit, in turn, sends operational signals to the devices that regulate the throttle position. The throttle position maintains the selected vehicle speed. The cruise control compares the actual speed of the vehicle to the selected speed. Then, the control unit uses the result of that comparison to open or close the throttle.

The control unit will disengage the instant the driver depresses the brake pedal. The brake switch sends an electronic signal to the control unit when the brake pedal is depressed; the control unit responds by allowing the throttle to close. The shift lever position switch (automatic transaxle) or the clutch switch (manual transaxle) sends a disengage signal input to the control unit that also allows the throttle to close.

The use of the speed control is not recommended when driving conditions do not permit maintaining a constant speed, such as in heavy traffic or on roads that are winding, icy, snow covered or slippery.
