Yaw Rate Sensor: Description and Operation

GF42.45-P-5120SX Yaw rate and lateral 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
Recording the rotational speed (yaw angle velocity) of the vehicle about the vertical axis as well as the lateral and longitudinal acceleration.

The ESP control unit determines the lateral forces at the wheels from the yaw angle velocity, the lateral and longitudinal acceleration and the steer angle of the front wheels which is calculated from the steering wheel angle (N47-5).

Design
Combined sensor for rotational speed and transverse and longitudinal acceleration in micromechanical construction
