Adaptive Speed Control

WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

The adaptive speed control system uses a forward looking radar sensor to scan the road ahead. The adaptive speed control system is looking for objects that are moving at a different speed than the sensing vehicle. When a target is identified the adaptive speed control system will monitor the time gap between the sensing and the target vehicles.

When the time gap falls below a set driver selected level, the speed control system will intervene. The speed control system will slow the vehicle by decreasing fueling and, or applying the brakes, until the correct time gap is attained. The driver can choose between 4 time gap settings. The chosen setting is displayed in the Instrument Cluster (IC).

The system will detect but not react to the following:

Vehicles in the oncoming lane
Stationary vehicles
Pedestrians.

Adaptive speed control is active at a minimum set speed of 16 km/h (10 mph) and a maximum of up to 200 km/h (124 mph). Adaptive speed control is also active 10 km/h (6 mph) below the declared maximum vehicle speed, whichever is lower. Adaptive speed control only functions when a set speed is entered in the system operating 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. The speed control system reduces the speed only if the minimum time gap is breached or if it calculates that the time gap will be breached.

It is important to note that the system is intended for use in limited driving situation and does not remove control and responsibility from the driver. That means the system can be quickly overridden at all times. The adaptive speed control system is not a collision warning system and will not react to stationary objects. The system is best suited to main roads/highways with gradual bends.

The adaptive speed control system only intervenes with the set speed when:

It detects a target vehicle
If the minimum time gap is breached or is about to be breached.

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.
