  • Patent number: 10982744
    Abstract: In at least some implementations, a system for a vehicle differential having multiple gears includes a coil of wire, a drive member movable in response to a magnetic field generated by application of electricity to the coil between a first position and a second position, and a lock member coupled to the drive member for movement with the drive member throughout a range of movement of the drive member. The lock member is adapted to engage a gear of the differential when the drive member is in the second position and the lock member is adapted to be disengaged from the gear when the drive member is in the first position. In this way, the differential may be selectively locked.

  • Publication number: 20170210389
    Abstract: A sensing system for a vehicle includes an electrical sensing circuit that has a first sensor and a second sensor. The sensing circuit is configured to provide a composite output signal that includes data from both the first sensor and second sensor.

  • Publication number: 20100179736
    Abstract: An electronic locking mechanism for a vehicle differential assembly includes a lock element movable in response to an actuation signal between an open position and a locked position. The lock element generally forces side gears of the differential assembly to turn generally at a same rate when the lock element is in the locked position. The electronic locking mechanism further includes a processor configured to determine a status of the differential assembly from a current profile that includes the actuation signal and an induced current. The determined differential assembly status is generally one of an “activated and locked” status, an “activated but unlocked” status, a “deactivated but locked” status, and a “deactivated and unlocked” status.
