Speed Control

Speed Control

The speed control system is integrated with the engine management system and uses fuelling intervention to automatically maintain a set vehicle speed. Once engaged, the system can also be used to accelerate the vehicle without using the accelerator pedal. The speed control system comprises the following components:
^ On/Off/Suspend switch
^ '+' and '-' (set/accelerate and decelerate)
^ Resume switch
^ Clock spring
^ Speed control warning lamp (in the instrument pack)

The speed control system also uses inputs from the brake pedal switch, the APP sensor, the ECM and the ABS ECU.

The speed control is operated by the driver using only the steering wheel switches. When speed is active, the ECM regulates the PWM signals to the fuel injectors to adjust the fuel supply as required to maintain the set speed.
