Claim Text:
1. A system for automatic wheel diameter determination, the system comprising: a first proximity plate having a first length and comprising a detectable material, the first proximity plate being positioned at a first location along a direction of motion of a vehicle; a sensor on the vehicle configured to generate a first signal including an indication of detection of the detectable material of the first proximity plate at a start of the first length and an indication of loss of detection of the detectable material of the first proximity plate at an end of the first length; a signal generator on the vehicle configured to generate a second signal indicating a number of revolutions of a wheel on the vehicle; and a controller configured to receive the first signal and the second signal and determine a diameter of the wheel based on the first length, the indication of detection of the detectable material of the first proximity plate, the indication of loss of detection of the detectable material of the first proximity plate, and the number of revolutions of the wheel.
