A method for operating a drive apparatus including an internal combustion engine and an electric engine. An output shaft of the drive apparatus can be operatively connected to the internal combustion engine by way of a shifting clutch and can be permanently operatively connected to the electric engine, so that the output shaft is disengaged from the internal combustion engine in a first shifting state of the shifting clutch and is engaged with it in a second shifting state.

A method of controlling a drive axle system. The method may include executing a gear upshift or a gear downshift after decreasing the torque that is provided by an electric motor to a transmission of an axle assembly and increasing the torque that is provided by another electric motor to a transmission of another axle assembly.

An illustrative dual power inverter module includes a detection circuit configured to detect loss of low voltage DC electrical power supplied to a controller for a first power inverter and a second power inverter of a drive unit for an electric vehicle. A first backup power circuit is associated with the first power inverter and a second backup power circuit is associated with the second power inverter. Each backup power circuit is configured to convert high voltage DC electrical power to low voltage DC electrical power responsive to detection of loss of low voltage DC electrical power supplied to the controller. Three-phase short circuitry is configured to apply a same fault action to the first power inverter and the second power inverter responsive to detection of loss of low voltage DC electrical power supplied to the controller, wherein the same fault action includes applying equalized torque to each axle operatively coupled to the drive unit.

A control device for a hybrid vehicle includes a push-start mode and a motor start mode. The push-start mode transmits a driving force from driving wheels to the engine via a first transmission route at a speed detected by a speed detection means equal to or more than a predetermined speed to start the engine. The motor start mode starts the engine using a driving force of the motor at a speed equal to or less than the predetermined speed as well as in a stopped state. At a speed outside a speed range that either mode is executable when a start command of the engine occurs in driving only using the electric motor as the driving source, a control means performs the driving force reduction control for reducing a driving force transmitted from the electric motor to the driving wheels of the vehicle.

The present invention is an electronic gear-shifting device of an electric motorcycle for simulating gear shifting power output, including an electronic shift unit, an electronic clutch unit and a throttle position sensor, and correspondingly outputting a shift signal, a clutch signal and a throttle position signal according to the operation of the rider. A vehicle controller receives the shift signal, the clutch signal and the throttle position signal to determine a target gear position of the electric motorcycle. The vehicle controller looks up a motor torque command according to the target gear position table and outputs the motor torque command to a motor controller, so that the motor controller controls an electric motor of electric motorcycle. Therefore, the electric motorcycle simulates the power performance of a general motorcycle without adding a physical clutch, a gearbox and other shifting mechanisms.
