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.


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
