Abstract: Methods and systems are provided for operating a solenoid actuator to engage and/or disengage a torque transmission member of a vehicle transmission. In one example, a method may include increasing the holding force of the solenoid actuator. Additionally, the solenoid actuator may include a translatable structural element that creates a moment upon touching another structural element holding the translatable element in a locked position.

Abstract: Methods and systems for a locking differential are provided. The locking differential system includes an electromagnetic solenoid actuator designed to induce locking and unlocking of the differential and a circuit board assembly designed to programmatically control the locking and unlocking functionality. The circuit board assembly includes a sensor and control circuity enclosed in a continuous sealed enclosure, the sensor extends down the face of a coil assembly in the solenoid.

Abstract: Methods and systems are provided for a differential disconnect assembly of a vehicle, the differential disconnect assembly including a dog clutch used to engage and disengage a gear of a differential of the vehicle from a transmission of the vehicle. In one example, a method for operating a dog clutch comprises de-energizing a solenoid coupled to the dog clutch to initiate dog clutch disengagement; and during disengagement of the dog clutch when a return spring coupled to a first toothed interface of the dog clutch applies a first force on the first toothed interface in a first direction away from a second toothed interface, transiently re-energizing the solenoid that applies a second force to the first toothed interface in a second direction which is opposite the first direction.

Abstract: Methods and systems are provided for sensing a clutch position. In one example, a method may include generating a single output signal by combining at least an output of a first sensor and an output of a second sensor output, the first sensor and second sensor connected in parallel, and the first sensor and the second sensor sensing a common moving element of a clutch. In one example, the method may further include a first sensor output and a second sensor output provided on a common sensor bus. As another example, the first sensor output may be a master pulse width modulation output, and the second sensor output follows a modulation frequency of the first sensor output.
