Yaw Rate Sensor: Description and Operation

4559 - Yaw Velocity/Lateral Acceleration Sensor







The yaw velocity sensor and the lateral acceleration sensor are positioned within a housing and on the center console. The measuring element of the yaw velocity sensor is manufactured in micromechanics. Four acceleration sensors, located in pairs of two on two masses oscillating in phase opposition, measure the vehicle's linear proportions. These are translated into lateral acceleration and yawing speed in the evaluation circuitry and forwarded to the PSM control unit.
