EV DISCONNECT CONTROL

Abstract: systems and processes described herein can use drive line actuators (dlas) which can be implemented for one or more individual wheels of an electric vehicle (ev) permitting connection and disconnection of at least a portion of the axle and wheel from the electric motor suppling torque. a disconnected wheel and axle can experience less friction, and have less rotational mass then a wheel and axle that is connected to an electric motor, therefore the disconnecting wheels in which torque is not desired can result in increased efficiency and range in an ev.
