BMW 7 Series: Steering and traffic jam assistant


The system assists the driver in keeping the vehicle within the lane. For this purpose, the system executes supporting steering movements, for instance when driving in a curve.

General information

The system determines the position of the lane markings and the vehicle driving ahead using five radar sensors and a camera.

Depending on the speed, the system orients itself according to the lane markings or vehicles in front.

Sensors on the steering wheel detect whether the steering wheel is being touched.

Safety information


The system cannot serve as a substitute for the driver's personal judgment in assessing the traffic conditions. Based on the limits of the system, it cannot independently react to all traffic situations. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.
