Increase of cross-domain functions which influence the Vehicle Motion (lateral and longitudinal acceleration) are cased by
comfort, safety, autonomous and eco driving functions.
Complexity will be mastered by functional coordination of Vehicle Motion Control (arbitration/coordination of Vehicle Motion
Aggregates like braking, ICE, E-Machine & steering)
