lane change assistant (LCA)

Like the lane departure warning system (SWA), the lane change assistant is designed to improve driving safety. It warns the driver of possible collisions

when the vehicle changes lanes. Lane Change Assist works with various radar systems such as short-range

radar(SRR) and long-range radar (LRR), laser scanners and cameras. Radar sensors operate in the 77 GHz band and, for some years now, also in the 24 GHz band. In automotive technology

, they provide environmental information in a range of up to 250 m. They are used to detect objects - such as lanes - and also people. Inaddition to oncoming vehicles, the lane change assistant focuses on whether there is a motor vehicle in the adjacent lane and how fast it is approaching.

The task of the lane change assistant is to clearly assign the problem, to initiate a recognizable warning that can be assigned in all traffic conditions and to trigger a warning signal that attracts appropriate attention. Such a lane change assistant may trigger a visual, audible or haptic warning signal in case of danger. The latter may, for example, take the form of vibration of the steering wheel.
