Systems and methods of controlling a clutch in a hybrid vehicle with a manual transmission, are provided. With the goal of enabling autonomous/assisted clutch control in a hybrid vehicle, while preserving the familiar mechanical feeling at the clutch pedal that driving enthusiasts prefer, embodiments of the disclosed technology use a shuttle valve to blend control of clutch engagement between a driver and an ECU. In these embodiments, a clutch pedal in the vehicle may be mechanically connected to a piston in a first hydraulic cylinder (just like in a traditional mechanical/hydraulic clutch actuation system), and an ECU may actuate a second hydraulic cylinder. Accordingly, a shuttle valve may be used to route the fluid coming from the cylinder with the greater pressure (i.e. the driver actuated cylinder or the ECU actuated cylinder), to a third hydraulic cylinder which adjusts engagement of a clutch by a mechanical linkage.

A system for repositioning at least one battery of an electric-powered vehicle relative to a drive axle of the vehicle to increase the weight carried by the axle as the vehicle attains a predetermined speed.

A power take-off shaft system includes an output shaft with a socket for a power take-off shaft stub located at one end of the output shaft.

The vehicle transmission further includes a first disconnect device releasably mechanically coupling a first output to a first drive axle and a second disconnect device releasably mechanically coupling a second output to a second drive axle.

A vehicle control system for reducing shocks resulting from restarting an engine under EV running mode. The vehicle control system is applied to a vehicle including an engagement device that selectively connect the engine with the powertrain, and a motor adapted to generate a drive force and connected with the powertrain. In the vehicle, a first mode is selected to propel the vehicle by the motor while interrupting the torque transmission between the engine and the powertrain and stopping the engine, and a second mode is selected to propel the vehicle by the motor while allowing the torque transmission between the engine and the powertrain and stopping the engine. The vehicle control system selects the second mode if a control response of at least any of the engagement device and the motor is estimated to be out of a predetermine range when the vehicle is running while stopping the engine.
