Angular velocity (yaw)sensor (Mercedes-Benz Vito W639)

Hollow steel cylinder (sensitive element, b) under the influence of piezoelectric elements it begins to vibrate at a certain frequency. 4 pairs of piezoelectric elements are located on the cylinder opposite each other. Depending on the rotational movement of the vehicle, there is a shift in the parameters of the vibration occurring between the piezoelectric elements. These offsets serve as the basis for determining the angular velocity of the vehicle.
