Abstract: In an electrical drive system, an electric differential comprises a first rotor for driving a first drive wheel, a second rotor for driving a second drive wheel, the first and second rotors capable of independent relative rotation, and a common stator for driving the first and second rotors. The common stator may comprise a single winding for driving both rotors or first and second windings for driving the first and second rotors respectively. A processor and a sensor system monitor parameters such as torque, speed, magnetic flux, etc. to detect the loss of traction by one or both drive wheels and adjust the operation of the motor until traction is regained.

Abstract: A drive range selection employs both a movable shift actuating member that is operatively connected to a customary manual shift valve and a movable park lock actuating member that is operatively connected to a parking lock pawl mechanism. A force transfer device operatively connects the shift actuating member and the park lock actuating member to a selecting lever. Mechanism is provided to disengage the force transfer device from the shift actuating member when the force transfer device is operatively connected to the park actuating member, and to immobilize the shift actuating member in response to activation of the park lock actuating member when the force transfer device is disengaged from the shift actuating member.
