Adaptive Speed Control

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead, looking for objects that are moving at a different rate to itself. When a target is identified the adaptive speed control system will monitor the time gap between the host and the target vehicles. When the time gap falls below a set driver selected level, the speed control system will intervene, slowing the vehicle by backing off the throttle and/or applying the brakes, until the correct time gap is attained. The driver can chose between four time gap settings. The chosen setting is displayed in the instrument cluster.

The system will detect but not react to the following:

• Vehicles in the oncoming lane
• Stationary vehicles
• Pedestrians.

Adaptive speed control is active when the vehicle is moving at a minimum speed of 32 km/h (20 mph) and a maximum of 200 km/h (120 mph). Adaptive speed control only functions when a set speed is entered in the system using the SET '+' switch on the steering wheel switchpack. The adaptive speed control system only intervenes with the set speed when it detects a target vehicle, and then only if the minimum time gap is breached or is about to be breached.

It is important to note that the system is intended for use in limited driving situations, does not remove control and responsibility from the driver, and at all times can be quickly overridden. The adaptive speed control system is not a collision warning system and will not react to stationary objects. The system does not operate below a minimum speed of approximately 32 km/h (20 mph) since it is unsuitable for use in cities or congested traffic. The system is best suited to main roads/highways with gradual bends.

The adaptive speed control system is controlled by an Adaptive Speed Control Module (ASCM).

The adaptive speed control system also uses the Anti-lock Brake System (ABS) control module.
