Abstract: According to one aspect, a vehicle control system. The control system includes a steering control coupled to at least one steerable wheel, the steering control having a first position, a second position and a plurality of positions therebetween. The control system also includes a steering sensor coupled to the steering control and configured to generate steering sensor signals based upon the position of the steering control. The control system also includes a control module coupled to the steering sensor, the control module configured to (i) record a first steering sensor signal value when the steering control is in the first position; (ii) record a second steering sensor signal value when the steering control is in the second position; and (iii) determine a current position of the steering control by comparing the first and second steering sensor signal values with a current steering sensor signal value.
