One embodiment relates to a hybrid vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable power source, and a PTO. The hybrid vehicle drive system further includes a hydraulic motor in direct or indirect mechanical communication with the PTO and an electric motor in direct or indirect mechanical communication with the hydraulic motor. The electric motor can provide power to the prime mover driven transmission and receive power from the prime mover driven transmission through the PTO. The hydraulic motor can provide power to the prime mover driven transmission and receive power from the prime mover driven transmission through the PTO.

Hybrid vehicle drive system and method and idle reduction system and method

When a crank angle is controlled to stop at an optimal crank angle stop position by an engine automatic stop control, such as idling stop, or when the crank angle stop position can be estimated with high accuracy, the automatic engine restart is performed by a motor generator serving as an electric motor or an electric generator, at the next time of restarting of the engine. On the other hand, when the crank angle is not controlled to stop at the optimal crank angle stop position, when the crank angle stop position cannot be estimated with the high accuracy, or when the crank angle stop position changes after the stop control, the engine is restarted by a DC starter having an output torque larger than that of a motor generator, at the next time of restarting of the engine.

An electrical energy storage device for storing electrical energy and supplying the electrical energy to a driving motor at different power levels is disclosed. The electrical storage device has an energy battery connected to a power battery. The energy battery has a higher energy density than the power battery. However, the power battery can provide electrical power to the electrical motor at different power rates, thereby ensuring that the motor has sufficient power and current when needed. The power battery is continuously recharged by the energy storage battery. In this way, the power battery temporarily stores electrical energy received from the energy battery and provides the electrical energy at the different power rates as required by the motor. The energy storage device can be releasably connected to an external power source in order to recharge both batteries. Both batteries can be recharged independently to optimize the recharging and lifetime characteristics of the batteries.

A battery module for use with a vehicle electrical system. The battery module includes a bi-directional battery voltage converter, a first battery, and a second battery. A first relay selectively connects the first battery to the bi-directional battery voltage converter. A second relay selectively connecting the second battery to the bi-directional battery voltage converter. A controller selectively energizes the first relay, selectively energizes the second relay, and controls a direction of current through the bi-directional battery voltage converter.

A device for driving auxiliary units of motor vehicles is proposed, using the combustion engine (1) as drive means. The device is so designed that the combustion engine (1) itself drives the auxiliary units (2, 3, 4, 5) only at low speed and/or load and that at higher speed and/or load of the combustion engine (1) the auxiliary units (2, 3, 4, 5) are driven by a turbine (9) arranged in the exhaust gas duct of the combustion engine (1).

The invention relates to a method for regulating a generator in a motor vehicle, according to which the generator supplies power to a vehicle electrical system provided with consumers and with at least one battery, whereby a regulator adjusts the generator voltage to the value of the set value voltage. During a recuperation stand-by mode, the set value voltage is specified according to the driving state quantities as to enable electric power to be fed into the vehicle electrical system during braking or overrunning of the vehicle. According to the invention, a change-over is effected between the recuperation stand-by mode and a recovery mode according to specified change-over conditions, whereby the set value voltage is specified in the recovery mode as to permit the battery to regenerate itself.
