Yaw Rate Sensor: Description and Operation
Yaw Sensor (658)
On cars equipped with ESP
Main Use
The sensor is used to measure the physical forces of the yaw rate and the lateral acceleration of the vehicle.
Type
The sensor comprises a combined micromechanical yaw rate sensor and lateral acceleration sensor.
A hermetically sealed metal housing protects the components from being affected by its surroundings.
The centre of the combined micromechanical sensor consists of a silicone ring gyro containing three layers of silicone with intermediate isolation of thin glass, eight radial spokes which detect rotation movement and a capacitive element which detects lateral acceleration movements.
