| Abstract: |
A apparatus and method for detecting an out-of-alignment condition of a wheeled vehicle with at least one steered wheel controlled by a steering wheel by comparing the relative number of periodic samples during a sampling period in which the vehicle steering wheel is positioned right of the center position as compared to left of the center position.

We claim:
1. An apparatus for detecting an out-of-alignment condition of a wheeled vehicle with at least one steered wheel controlled by a steering wheel by comparing the relative number of periodic samples during a sampling period in which the vehicle steering wheel is positioned right of the center position as compared to left of the center position, the apparatus comprising;
- sampler that periodically samples the position of the steering wheel and determines whether the steering wheel is in a center position, or a left position left of the center position, or a right position right of the center position,
- fault determiner that determines a left fault condition when the number of samples in the left position exceeds the number of samples in the right position by a first predetermined number during the sampling period, or determines a right fault condition when the number of samples in the right position exceed the number of samples in the left position by the first predetermined number during the sampling period,
- auto-reset that initiates a new sampling period when a left fault condition is determined, or a right fault condition is determined, or the number of samples made by the sampler during the sampling period reaches a second predetermined duration number,
- a status indicator that indicates to a user a left failure or a right failure based upon a comparison of accumulated right fault conditions and accumulated left fault conditions over one or more sampling periods.
