XIV - CRUISE CONTROL
The cruise control device is used to maintain the vehicle speed at a value
programmed by the driver in the following cases:
• when the accelerator pedal is not pressed,
• regardless of the road profile,
• without pressing the brake pedal.
Possibilities offered by the cruise control device:
• the driver can exceed the programmed speed by pressing the accelerator pedal,
• the driver can cancel cruise control by pressing the brake pedal, the cruise control
switch or the on/off button.
Note: The cruise control device can only be used above 40 km/h.
Operation.
When cruise control is on, the injection ECU permanently compares the programmed
speed with the vehicle's instantaneous speed.
The speed information is supplied by the speed sensor.
When the programmed speed is greater than the vehicle's current speed, the
injection ECU increases the fuel flow: the vehicle accelerates up to the programmed
speed.
When the vehicle's current speed is greater than the programmed speed, the
injection ECU reduces the fuel flow: the vehicle decelerates down to the programmed
speed.
Cruise control is cancelled by pressing:
• the accelerator pedal,
• the clutch pedal,
• the on/off button,
• the brake pedal.
Note: In the above 4 cases, the vehicle decelerates very quickly (accelerator
released without declutching).
When cruise control is cancelled by pressing the cruise control button, the vehicle
decelerates slowly.
