OPERATION

The Yaw Rate/Lateral Acceleration Sensor is a combined sensor.

The yaw rate portion of the sensor is used to measure the yaw rate of the vehicle. When the vehicle turns, acceleration forces are produced which cause torsion. This torsion change within the sensor is proportional of the yaw rate of the vehicle.

The lateral acceleration portion of the sensor measures the amount of lateral acceleration during cornering. This sensor uses a spring/mass type element to measure the amount of lateral acceleration. The lateral acceleration that occurs during cornering causes the spring/mass element to move from its normal position to a position corresponding to the magnitude of the lateral acceleration. Every change in the spring/mass element position changes the output voltage of the sensor.
