System Outline
The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal.
- Set Operation
When the cruise control main SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicator light in the combination meter.
- Set Speed Control
When the - SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed is controlled.
- Coast Control
When the - SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to decelerate the vehicle. Every time the - SET SW is turned on momentarily, the vehicle speed is decelerated by approximately 1.6 km/h.
- Accel Control
When the + RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve to accelerate the vehicle. Every time the + RES SW is turned on momentarily, the vehicle speed is accelerated by approximately 1.6 km/h.
- Resume Control
If the cruise control is cancelled, use of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control.
- Manual Cancel Mechanism
If any of the following signals is input during cruise control travelling, the cruise control is cancelled.
* The stop light SW is turned on.
* The CANCEL SW is turned on.
* The cruise control main SW is turned off.
- Auto Cancel Function
