Abstract
Information related to the rotary angular position of a steerable wheel portion of an electric vehicle is required for proper control of the vehicle and especially for differential control of the driven wheels of the vehicle. Available rotary position encoders are expensive, prone to damage in an industrial environment, and sensitive to misalignment between the encoder components. The instant apparatus provides a simple and durable rotary position encoder having a plurality of sensors positioned on a first mounting member and a plurality of sensible members positioned on a second mounting member. The apparatus is digital in design and the particular location and arrangement of the sensors and sensible members advantageously compensates for overtravel and misalignment of the encoder components.
