Adaptive Speed Control System Restrictions
The adaptive speed control system is only intended to provide enhanced speed control in certain restricted conditions. The following illustration shows circumstances where the adaptive speed control system may brake late or unexpectedly. The driver is required to intervene in these situations.
| ITEM | DESCRIPTION |
|---|---|
| 1 | Driving on a different line to the vehicle in front. |
| 2 | Vehicles that merge into the same lane are only detected when they have moved fully into the lane. |
| 3 | On bends in the road there can be issues with detection of the vehicle in front when going into and coming out of a bend. |
| 4 | Moving around a stationary vehicle may cause uncertainty regarding which vehicle is being followed. |
| 5 | A vehicle in front moving out of your lane may cause uncertainty regarding which vehicle is being followed. |
On the approach to, or exit from a bend, a target vehicle may be lost or a new target may have been discovered. The vehicles ahead change their angular position with respect to the Adaptive Speed Control Module (ASCM). If the sensing vehicle is in follow mode losing the target vehicle, it will cause the sensing vehicle to increase its set speed. This acceleration is undesirable either on a bend in the road, or entering a bend in the road when the target is suddenly lost. In this situation the system inhibits the resumption of the set speed.
