Yaw Rate Sensor: Description and Operation

GF42.45-P-4810CA Yaw rate, lateral and longitudinal acceleration sensor, component description

Component Identification:

Location
The yaw rate, lateral and longitudinal acceleration sensor is located below the driver's seat on the vehicle floor.

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 signals are sent over the vehicle dynamics CAN (CAN H) to the Electronic Stability Program control unit (N30/4) (except code (233) DISTRONIC PLUS) or to the Electronic Stability Program Premium control unit (N30/7) (with code (233) DISTRONIC PLUS).
