A method for controlling a mild hybrid vehicle may include determining, by a controller, whether an engine of the mild hybrid vehicle operates based on a demand torque of a driver of the mild hybrid vehicle; determining, by the controller, a torque of a starter-generator of the mild hybrid vehicle that assists a torque of the engine according to the demand torque of the driver based on a temperature of a turbocharger of the mild hybrid vehicle when the engine is operated; and operating, by the controller, the starter-generator to assist the torque of the engine based on the determined torque of the starter-generator.

Methods and systems are provided for expediting charging of a battery before entry into a zero emissions zone. In one example, the battery is charged with a ratio of motor torque drawn from a first electric motor of an electric turbocharger and a second electric motor of an HEV driveline. The ratio is coordinated with adjustments to an exhaust waste-gate and an intake throttle so as to maintain operator torque demand and propel the vehicle while charging the battery.

A variable speed hybrid electric supercharger assembly is controlled to regulate an adaptive state of charge of an energy storage device and/or to boost an engine based on a performance mode selected by a driver. In one example, a reference state of charge is determined based upon driving characteristics of a vehicle and compared to an actual state of charge of the energy storage device. If the difference indicates a deficit, an operation mode is selected to regenerate the energy storage device. In another example, a planetary gearing arrangement between an engine and an electric motor is configured to increase or decrease power transferred to the supercharger by the engine based upon the performance mode selected by the driver.

A mobile diesel generator and propulsion system preferably includes a diesel engine, a vehicle platform, a generator with voltage inverter, a battery charging system, at least one storage battery, an AC voltage to DC voltage converter, a motor controller and an AC motor. The generator with voltage inverter is driven by the diesel engine. The battery charging system receives AC voltage from the generator with voltage inverter and outputs a DC voltage to charge the at least one storage battery. The AC voltage to DC voltage converter receives output from the generator with voltage inverter and outputs a DC voltage to the motor controller. The motor controller receives DC voltage output from either the AC voltage to DC voltage converter or the at least one storage battery and outputs AC voltage to the AC voltage motor. The AC voltage motor drives a rear wheel of the vehicle platform.

A controller is provided for a hybrid system including an electric supercharger, a motor generator, and an energy storage system for supplying electric power to the electric supercharger and the motor generator controls the electric supercharger (and the motor generator in accordance with a required torque. Specifically, even when the required torque can be achieved by an engine alone, the controller for the hybrid system activates at least one of the electric supercharger and the motor generator to provide torque assist to the engine when the state of charge of the energy storage system is sufficiently high.

An electric vehicle includes: an intake device provided upstream of an intake pipe of an engine; a power transmission device configured to transmit a power of an electric motor to drive wheel; an electric-power control device configured to control an electric power transferred between a driving battery and the electric motor; and a charger configured to charge the driving battery with the electric power supplied from an external power supply. The electric motor and the power transmission device constitute at least a part of a driving apparatus. The driving apparatus and the electric-power control device constitute a mechanical-electrical integrated unit which is housed in a single casing and which is located in a position adjacent to the engine. The charger and the intake device are located on an upper side of the mechanical-electrical integrated unit in a vertical direction of the electric vehicle.

A hydrogen fueled powerplant including an internal combustion engine that drives a motor-generator, and has a two-stage turbocharger, for an aircraft. A control system controls the operation of the motor-generator to maintain the engine at a speed selected based on controlling the engine equivalence ratio. The control system controls an afterburner, an intercooler and an aftercooler to maximize powerplant efficiency. The afterburner also adds power to the turbochargers during high-altitude restarts. The turbochargers also include motor-generators that extract excess power from the exhaust.

An operating method for a driver assistance system, in particular a cruise control system of a motor vehicle. The operating method comprises determining at least one operationally relevant road property of a road on an impending route of the motor vehicle, wherein the operationally relevant road property affects operation of an internal combustion engine of the motor vehicle.
