A sensor assembly configured for use with a locking differential received in a differential case includes a sensor housing, a switch element and a sense element. The sensor assembly is configured to determine a position of an armature in relation to a stator. The armature moves relative to the stator between engaged and disengaged positions corresponding to the locking differential being in a locked and unlocked state. The sensor housing is coupled relative to the differential case of the locking differential. The switch element is disposed in the sensor housing. The sense element moves with the armature. The sensor assembly is configured to change state based on a position of the sense element.

Differential lock/unlock position detection

Receiving sensor data related to position of a gear in a transmission, the sensor data including data from a first sensor and data from a second sensor; determining a first indicated position of the gear from the data from the first sensor; determining a second indicated position of the gear from the data from the second sensor; comparing the first indicated position to the second indicated position; and determining based on the comparison a gear engagement status of the gear.

Shift rail transmission position sensing

A two-wire system for monitoring fluid level and temperature including a pair of electrical interconnect wires bridged by a fluid level switch and a thermal sensing element. One of the fluid level switch or the thermal sensing element bypasses the other during a trigger event.

Two wire temperature and fluid level limit switch

A number N of position sensors, each associated with one of N shift rails in a shift rail transmission system, wherein the set of N sensors is divided into subsets and each subset is provided a common reference from a control module; and a processing component that determines from data from each sensor whether the shift rail associated with that sensor is in a position of engagement of a first gear, a position of engagement of a second gear, or in a neutral position. Further, providing a first common reference to a first set of shift rail position sensors; providing a second common reference to a second set of shift rail position sensors; receiving sensor data from each position sensor; determining that the data from the first set of position sensors is unreliable; and operating a transmission using only the gears related to the position sensors in the second set.
