Yaw Rate Sensor: Description and Operation

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

Component Identification:

Location
The turn rate, lateral and longitudinal acceleration sensor is located in the luggage compartment in the center at the partition wall to the passenger compartment.

Task
The yaw rate sensor for lateral and longitudinal acceleration measures the rotational speed about the vehicle perpendicular axis. The integrated lateral acceleration sensor (AY sensor) measures the lateral acceleration.

The data from the yaw rate sensor for lateral and longitudinal acceleration are read in by the ESP control unit (N47-5) via the vehicle dynamics CAN.

Design
The yaw rate sensor for lateral and longitudinal acceleration is a combined sensor for yaw rate, lateral and longitudinal acceleration in micromechanical construction.
