RV-4 sensors are mechanical systems which are designed for measuring space and direction coordinates of the vehicle wheel. The sensors carry out all movements with the wheel, except for the rotation about the wheel axis. Provided an adequate sampling rate of the articulation positions, it is possible to simulate wheel movements of a complete test drive. RV-4 sensors consist of five absolutely measuring high precision angle transducers. Together, these measure the space coordinates in a vehicle-related coordinate system: Steer angle, camber, x-movement, y-movement, and z-movement (spring travel). By using the RV-4 sensors with a wheel force transducer the forces and torques of a vehicle wheel can additionally be measured. An optional wheel pulse transducer can be used to determine wheel speed.
