AbstractA sensor for automotive vehicles with electronic control of the driving and braking behavior and/or of vibration damping in dependence on the rotational wheel speed and on the vertical acceleration of the vehicle, the sensor designed as a dual-function or multiple-function sensor by combining and structurally uniting an inductive or magnetoresistive transducer for monitoring rotational wheel velocity and a vertical acceleration sensor system for monitoring vertical vehicle body motion and, if applicable, other sensors. The measured signals are led from the sensor to signal processing circuitry via common output signal line.
