Abstract
A system for controlling a steering motor for turning a steerable vehicle wheel. The system includes a shaft which is angularly rotatable about its longitudinal axis. The system includes a plurality of sensors. Each of the plurality of sensors provides a signal. The signal of each of the plurality of sensors is indicative of the rotational position of the shaft for different portions of a revolution of the shaft. At least one signal is indicative of the rotational position of the shaft for each rotational position of the shaft. The signal of each of the plurality of sensors being non-indicative of the rotational position of the shaft for different and non-overlapping portions of the revolution of the shaft. A control means receives the signals indicative of the rotational position of the shaft. The control means operates the steering motor alternately in response to first and second signals provided by the sensors.
