Lane Change Assist (LCA)
Lane Change Assist (LCA)
The optional Lane Change Assist (LCA) is used for the first time on the new Cayenne. Lane Change Assist is a vehicle assistance and comfort system that monitors the lanes on the left and right up to 230 ft (70 meters) behind the vehicle, including the blind spot, by way of two radar sensors mounted in the left and right of the bumper. This enhances driving comfort and safety, particularly when driving on the Motor-way.
LCA is available in the speed range between 19 mph (30 km/h) and max. 160 mph (250 km/h). If a vehicle is in the blind spot or is approaching quickly from behind, an LED information display on the inside of the corresponding door mirror lights up from a distance of 180 ft (55 meters) mirrors for this purpose.
If the driver activates the direction indicator in this situation, the information display flashes brightly to give the driver a clear warning (warning stage) of the approaching vehicle. This information is given in two stages: As long as the driver does not indicate, the light indicates vehicles detected in neighboring lanes discretely and inconspicuously. Lane Change Assist decides whether to display the vehicle based on relative speed and distance. However, if the driver sets the direction indicator, the light flashes brightly to warn him of the detected vehicle.
NOTE:
- LCA is deactivated when towing a trailer.
- The system saves the last system mode (activated or deactivated) as well as the selected LED brightness for a specific key.
LCA does not actively intervene in the controlling of the vehicle and can be deactivated at any time by the driver by way of a button in the door switch module. When LCA is activated via the LCA button, the system provides visual feedback through the brief lighting up of both LED modules in the door mirrors. There is no feedback from the system when LCA is deactivated. The LCA activation state can be read off using the function light in the button panel (door switch module).
The basic brightness of the LED modules (information display) can be adapted to driver requirements via a menu in the instrument cluster with three brightness levels. The effective brightness of the information display depends on this basic setting and is adjusted in parallel with the current outside brightness.
The range of the radar sensor depends to a large extent on the weather conditions. Temporary non-availability due to dirt on the bumper and/or poor weather conditions (fog, spray behind the vehicle etc.) or a potential system fault is indicated by way of text messages in the instrument cluster and leads to automatic deactivation of the system. It is reactivated by switching it on again manually.
