Provided herein is a vehicle including: an electric axle powertrain including: a continuously variable electric drivetrain comprising a motor/generator and a ball-type continuously variable planetary (CVP), a drive wheel axle operably coupled to the continuously variable electric drivetrain, and a first wheel and a second wheel coupled to the drive wheel axle; and a controller configured to control a CVP speed ratio and determine a request for torque vectoring, wherein the controller commands a change in the CVP speed ratio based on the request for torque vectoring,

An electro-magnetically actuated pawl clutch is adapted to establish a fixed overdrive ratio in a powersplit type hybrid gearing arrangement. The electro-magnetically actuated clutch includes a first race splined to the transmission input shaft and a second race integrally formed into a first gear that is supported for rotation about the input shaft. Electrical current in a non-rotating coil establishes a magnetic field in the first race. The magnetic field causes a set of pawls to pivot with respect to the first race and to engage a cam surface in the second race. The pawls and cams are designed such that, when engaged, the second race can rotate faster than the inner race but cannot rotate slower. The first gear meshes with a second gear fixed to the transmission output shaft.

A control system for an engagement device that engage the engagement device promptly to reduce a power loss is provided. The control system has a controller configured to start controlling a first motor in such a manner as to synchronize a rotational speed of a first engagement element to a rotational speed of a second engagement element, simultaneously with a commencement of engagement of the first engagement element with the second engagement element, or after the commencement of the engagement of the first engagement element with the second engagement element.
