    摘要: A fault-tolerant gear selector lever position apparatus is described. Included is a first sensor operable to detect each position, and a second sensor operable to detect subsets of the positions. A first controller monitors the second sensor, and a second controller monitors the first sensor. The second controller identifies and communicates one of the positions to the first controller, and the first controller validates the position and communicates the position to a control system. The lever is applicable to a power transmission device. Each sensor preferably comprises digital encoding sensor; the first sensor generates a unique signal for each position, and the second sensor generates a unique signal for each subset of the positions, preferably a unique signal for each of Park, Reverse, Neutral, and Forward Drive. The controllers identify faults in the sensors, and communicate and act accordingly.

    摘要: A method and an article of manufacture are provided to monitor a temperature sensing circuit and detect a fault therein. The method comprises monitoring sensor readings output from a plurality of temperature sensing circuits. An average sensor reading is determined, calculated from the sensor readings output from a subset of the temperature sensing circuits. Each of the sensor readings is compared to the average sensor reading. A fault is identified when one of the sensor readings deviates from the average sensor reading by an amount greater than a threshold, more particularly when one of the sensor readings deviates from the average sensor reading by an amount greater than the threshold at least a quantity of X times out of Y sensor readings.
