Task 

The yaw rate, lateral and longitudinal acceleration sensor measures the rotational speed about the vertical axis. The integrated lateral acceleration sensor

(AY-sensor) measures the lateral acceleration. The integrated longitudinal acceleration sensor (Ax sensor) detects longitudinal inclination.

The yaw rate, lateral and longitudinal acceleration sensor passes on the information to the ESP control unit via the Controller Area Network (data bus/CAN bus) (CAN)N47-5.
