Abstract: Methods and apparatus are provided for moving a receiver associated with a hitch frame of a vehicle. The method includes receiving data indicating a hand wheel angle; determining, with a processor, a position for the receiver relative to the hitch frame based on the hand wheel angle; and outputting one or more control signals to a motor coupled to the receiver to move the receiver relative to a longitudinal axis of the vehicle based on the determination.

Abstract: Methods and systems for controlling torque for a front axle and a rear axle of a vehicle with independent front and rear propulsion systems are provided. A data unit is configured to obtain data for one or more parameters of a vehicle while the vehicle is being driven. A processor is coupled to the data unit, and is configured to provide torque to at least facilitate providing torque the front axle and the rear axle independently based on the one or more parameters.

Abstract: Systems and methods are provided for diagnosing stator windings in an electric motor. An exemplary method for diagnosing stator windings in an electric motor involves determining an input energy imbalance across phases of the stator windings for an electrical period of the electric motor and identifying a fault condition when the input energy imbalance is greater than a first threshold value. In some embodiments, an input energy ratio across phases of the stator windings is also determined for the electrical period, wherein the fault condition is identified as a phase-to-phase short circuit fault condition when the input energy ratio is greater than a second threshold value and the input energy imbalance is greater than the first threshold value, or alternatively, as an in-phase short circuit fault condition when the input energy ratio is less than the second threshold value.
