BMW 7 Series: Steering and traffic jam
assistant
Concept
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
Warning
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.

Wheel speed sensors

(DF11i made by Robert Bosch
GmbH).
They are four active wheel-speed sensors, all four of which are connected by
dedicated two-core leads directly
to the DSC control unit. The wheel-speed data is trans
