BMW 5 Series: 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.
• The four side radar sensors monitor the area around the vehicle. The data from the KAFAS stereo camera is also analyzed and in this way a possible free space for an avoidance maneuver can be identified.
• A target trajectory (also known as a path curve), that is the "escape track" itself, is calculated in the Optional Equipment System (SAS) control unit.
• The driving dynamics function software in the Dynamic Stability Control (DSC) control unit calculates a target steering torque based on the "escape track".
• The target steering torque is converted to an engine torque by the Electronic Power Steering (EPS), which finally results in a supporting steering intervention, if necessary.

  The maximum steering torque has been set in such a way that it can always be overruled by the driver and therefore steering past the maximum steering torque is possible.
