Driver Assistance

A brief distraction or loss of concentration can often be enough to cause the driver to leave the lane unintentionally. This can lead to serious crashes.

Lane Assist System uses a video camera to detect lane markings ahead of the vehicle and to monitor the vehicle's position in its lane. When the function detects that the vehicle is about to unintentionally move out of the lane, it warns the driver by means of a visual, audible and/or haptic signal. These warnings signal the driver that the vehicle is drifting off course, allowing him/her to counter steer accordingly.

Monotonous driving, e.g. on expressways, is exhausting and quickly leads to loss of concentration. Based on steering-angle data, the function Driver State Monitoring continuously analyzes the steering behavior of the driver to identify phases during which the driver is not concentrated or tired. The function combines the frequency and strength of driver reactions with other data such as vehicle speed, time of day and use of other indicators to calculate a tiredness index. If this index exceeds a specific value, a visual and/or audible signal can warn the driver of becoming tired reminding her/him of the danger of nodding off at the wheel.

In combination with a navigation system, for example, it is possible to display the next available opportunity to stop or take a rest break.
