In general, this disclosure relates to a system and method of control for driveline actuators (DLAs) in the powertrain of an electric vehicle to perform shifting between two-wheel drive (2WD) and four-wheel drive (4WD) configurations. Sequential and overlapping shift process is used. The first disconnect is instructed by a vehicle control system to begin its shift, which takes approximately 100 milliseconds to complete. A short period of time after the first disconnect is instructed to begin its shift, but before it has completed the shift, the second disconnect is instructed to begin.

Electric vehicle four-wheel drive shifting control

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

Winch including a motor mounted contactor

Motorized disconnect assembly

Methods and systems are provided for adjusting operation of a motor of a winch. In one example, a system for a winch includes a controller adapted to adjust operation of a motor of the winch based on one or more of and/or each of a winch load limit, a motor temperature, a distance of a hook coupled to an end of a rope of the winch to a winch fairlead, and an amount of rope wound onto a drum of the winch.

Programmable controls for a winch

Methods and systems are provided for a motorized disconnect operable to selectively engage and disengage two rotating components of a vehicle drivetrain. As one example, a motorized disconnect system is provided that operates via an electric motor and includes a shifter assembly with an oscillating gear track and cam profile for rotating the shifter assembly while moving it in an axial direction to selectively couple two rotating components.

Motorized disconnect system and operation methods

Methods and systems are provided for a winch including a motor and a contactor assembly positioned within a same housing. In one example, the contactor assembly is positioned at an end of an armature of the motor and may include a controller configured to control winch component operation. The contactor assembly is electrically coupled to the armature via a plurality of electrically conductive brushes.

Winch including integrated contactor and motor

Systems are provided for a fairlead, and in particular to fairlead including an integrated lighting system. In one example, a fairlead may comprise a frame, the frame including a central, first opening and a second opening disposed above the first opening. The second opening may house an integrated lighting system, the integrated lighting system including a plurality of lights.

Fairlead with a lighting system

Methods and systems are provided for operating an electromagnetic pulse disconnect assembly for selectively engaging two rotating components of a vehicle drivetrain. A disconnect assembly is needed that is not powered by vacuum diverted from an engine of the vehicle, as modern engines are being developed to reduce vacuum production and remove vacuum lines for powering peripheral devices such as disconnects. An electromagnetic pulse disconnect assembly is provided that operates via pulses of electrical current and includes an electromagnetic coil for translating a clutch ring assembly and a latching ring assembly to selectively couple two rotating components.

Electromagnetic pulse disconnect system and methods

Methods and systems are provided for a winch including a motor and a contactor assembly positioned within a same housing. In one example, the contactor assembly is coupled to the motor and includes two or more coils spaced apart from one another within a contactor housing of the contactor assembly and a brush assembly including a plurality of brushes surrounding a rotational axis of the motor and arranged axially to the motor armature.

A winch is provided including a rotatable drum and a gear train drivingly connecting a motor to the rotatable drum. The gear train includes a clutch that is operable to be disengaged to allow the rotatable drum to free spool. A clutch actuator is provided for disengaging the clutch and the clutch includes a pivoting pawl having a first end that engages a clutch dog of a planetary ring gear and the clutch actuator includes an electro-magnetic solenoid having a plunger that engages a second end of the pivoting pawl.

Remote winch clutch system

A winch includes a motor having a motor housing including a motor case and an integrated first drum support attached to the motor case for closing an end of the motor case. A gear reduction unit is drivingly attached to the motor and has a gear housing including a gear case and second drum support attached to the gear case. A tie plate is connected to the first and second drum supports. A control unit is removably mounted to the tie plate. A rotatable drum is supported by the first and second drum supports.

Winch

Methods and systems are provided for operating an electromagnetic coil assembly. As one example, a method comprises responsive to energization of an electromagnetic coil of an electromagnetic coil assembly, translating the electromagnetic coil along a central axis of the electromagnetic coil assembly toward a magnetic armature while maintaining the armature fixed along the central axis. The electromagnetic coil assembly may be utilized within various clutching, braking, or lever applications.
