Multiple-function motion sensor for automotive vehicle slip and attitude control
First Claim
1. A multiple-function sensor for use in an automotive vehicle equipped with electronic control of said vehicle'"'"'s behavior, and in particular control of driving and braking behavior and of vibrational damping, in dependence on a rotational velocity of at least one wheel and on a vertical acceleration of a portion of said vehicle'"'"'s body, wherein said sensor comprises a multiple-function sensor combining and structurally uniting at least two transducer systems, the transducer systems comprising a rotational wheel velocity sensor system in which an inductive transducer is arranged on the vehicle body near the periphery of a toothed disk attached to the wheel, the disk rotating along with the wheel, the transducer delivering an electric signal representative of the rotary motion of the wheel, and said transducer systems further comprising a vertical vehicle body acceleration sensor system.

Abstract
A 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.
