Transmission control module with multiple sensor inputs
First Claim
1. A transmission system comprising:
- a first sensor configured to measure a quantity and output a first signal representative of the quantity measured;
a second sensor configured to separately measure the quantity measured by the first sensor and output a second signal representative of the quantity measured; and
a transmission control module in communication with the first sensor and the second sensor and configured to process the first signal along a primary processing path and a secondary processing path, process the second signal along the primary processing path and the secondary processing path, compare the processed first signal to the processed second signal, and determine if the primary processing path and the first sensor are reliable.

Abstract
An exemplary transmission system includes a first sensor configured to measure a quantity and output a first signal representative of the quantity measured. A second sensor is configured to separately measure the quantity measured by the first sensor and output a second signal representative of the quantity measured. A transmission control module in communication with the first sensor and the second sensor is configured to process the first signal along a primary processing path, process the second signal along a secondary processing path, compare the processed first signal to the processed second signal to determine if the primary processing path is reliable, and compare the processed first signal to the processed second signal to determine if the first sensor is reliable.
