BMW 5 Series: Evasion Aid
Often a collision with another vehicle (at the end of a traffic jam for example) or obstacle can only be prevented by an avoidance maneuver. Since the driver's response time plays a decisive role in an avoidance maneuver just as in a braking maneuver, Evasion Aid is able to make a considerable contribution to avoiding an impending collision.
Evasion Aid supports the driver in such critical driving situations with a focused steering intervention if the driver needs to avoid an obstacle. The system also help keep the vehicle stable during and after the avoidance maneuver.
This is achieved by an interaction between the Dynamic Stability Control (DSC), the Electronic Power Steering (EPS) and the analysis of data from the assistance sensors.

Functional principle
An emergency avoidance maneuver takes place when a suddenly occurring
obstacle is detected in
front of the vehicle and the driver has to avoid this obstacle quickly and
without "significant" braking
System overview
Below we describe which main components or sensors are relevant to Evasion
Aid.
Object or obstacles are detected by means of the KAFAS stereo camera and
the ACC
Stop&Go front radar sensor.
Operation
A special precondition such as the individual configuration capability for
the system or deactivation of
this function only is not possible.
Evasion Aid can only be deactivated by switching off all

Idle state
Concept
If the vehicle is in idle state, it is switched off. All
power consumers are deactivated.
General information
The vehicle is in idle state prior to opening from
the outside and after exiting and locking.
Safety information
Warning
An unsecured vehicle can begin to move and
possibly roll away
