The power train of a motor vehicle employs a hybrid drive including a combustion engine and an electrical machine. The transmission of the power train is shiftable into different gears in dependency upon the operating conditions of the vehicle. Such conditions include a traction condition when the vehicle is propelled by the engine and/or by the electrical machine, a coasting condition when the vehicle is being decelerated with attendant conversion of kinetic energy into electrical and/or rotational energy and storage of converted energy, a cold starting condition when the cold engine is started by the electrical machine, and a warm starting condition when the hot engine is started by the electrical machine and/or by at least one flywheel.

Power train with hybrid power source

A power train for a motor vehicle including an internal combustion engine, a power transmission, and an energy converter positioned between the engine and the transmission. A first clutch is positioned between the engine and the energy converter and a second clutch is positioned between the power transmission and the energy converter. The energy converter is operatively connected with at least one accessory for driving the accessory by energy derived either from the rotational motion of the engine crankshaft or from rotational motion transferred from the vehicle's drive wheels through the transmission.

Drive systems for a motor vehicle and methods for operating the same

The invention concerns a drive system, especially for a motor vehicle, with a multicylinder internal combustion engine, a device for shutting off at least some of the cylinders of the internal combustion engine, and a device for active reduction of rotational nonuniformities, acting in particular on a shaft, such as a drive shaft of the internal combustion engine, or a shaft that is coupled or which can be coupled to it, which is active at least for certain operating states during cylinder shutoff mode. A method of operating such a drive system is also disclosed.

Starter system and methods for starting an internal combustion engine

A method for starting an internal combustion engine and a starter system is disclosed. The crankshaft of an internal combustion engine is accelerated at least to the starting speed required for starting the internal combustion engine. The crankshaft is brought to a stipulated crank angle for the starting process by an electric machine before the actual starting process, and the starting process is started from this crank angle.

An apparatus for retarding an increase in braking torque associated with connecting an electrical consumer to a power supply of a drive system of a vehicle such as an internal combustion engine is disclosed. The apparatus includes a generator operatively connected to the drive engine. The generator serves to supply one or more electrical consumers. The apparatus also includes a control system which causes the generator to subject the drive engine to a slowly increasing braking torque during engagement of one or more electrical consumers to thereby provide time for performance of an ignition or filling intervention to ensure the increased load of the added consumer(s) does not cause undesirable effects in engine performance.
