Abstract
The present invention provides a system for controlling a vehicle comprising a prime mover, a first sensor, a transmission, a second sensor, and a transmission controller. The first sensor outputs a first signal that indicates a speed of an input shaft of the transmission and the second sensor outputs a second signal that indicates a speed of the prime mover. The transmission controller includes control logics that control the transmission using the first signal, perform a diagnostic check on the first sensor, determining whether the diagnostic check of the second control logic indicates that the first sensor meets a predefined performance characteristic, instruct the transmission controller to use the second signal of the second sensor to control the transmission if the third control logic indicates that the first sensor does not meet the predefined performance characteristic, and control the transmission using the second signal of the second sensor.
