PURPOSE: A steering position sensor assembly utilizing an angular velocity sensor is provided to obtain an apparatus for providing a signal representing the current angular position of a vehicle steering wheel from data provided by the angular velocity sensor. CONSTITUTION: A vehicle chassis(10) comprises a steering angle sensor assembly. The vehicle chassis includes a pair of front tire and wheel assemblies(12) which are interconnected by a bi-directionally, transversely translating linkage(14) which is driven and positioned by a steering box(16). The linkage and steering box may be one of numerous types of assemblies such as recirculating ball, rack and pinion or any other known assembly which converts the bi-directional rotation of a steering column(20) and a steering wheel(22) into corresponding bi-directional transverse translation of the linkage and bi-directional pivoting motion of the front tire and wheel assemblies in accordance with conventional practice. Disposed at a convenient location on the rotating steering column is a tone wheel(24) having plural distinct teeth(26). Disposed in proximate, sensing relationship with a tone wheel and the teeth is a rotary or angular velocity sensor(30). The rotary or angular velocity sensor includes three output lines(32,34,36) which carry three distinct, independent signals. The signals are provided to a microprocessor or electronic computation unit(ECU)(40).
