Position estimate for disconnect device in driveline for vehicle

A method of estimating a current position of a disconnect device on a vehicle, the method comprising:

• obtaining, via one or more processors, electrical operating characteristics of a solenoid configured to move the disconnect device between a first position in which the disconnect device engages a differential gear of the vehicle and a second position in which the disconnect device is disengaged from the differential gear;
• estimate, via the one or more processors, an inductance of the solenoid based, at least in part, on the electrical operating characteristics of the solenoid;
• and
• estimate, via the one or more processors, the current position of the disconnect device as corresponding to the first position or the second position.

A computing system, comprising:

• one or more memories comprising processor-executable instructions;
• and
• one or more processors coupled to the one or more memories and configured to execute the processor-executable instructions to cause the computing system to:
• estimate an inductance of a solenoid configured to move a disconnect device between a first position in which the disconnect device is configured to engage a differential gear and a second position in which the disconnect device is configured to disengage the differential gear;
• and
• estimate, based on the estimated inductance of the solenoid, a current position of the disconnect device as corresponding to the first position or the second position.
