Shown An internal combustion engine in idle

The internal combustion engine drives the electric machine 1 (A79/1) which operates as an AC generator which charges the high-voltage battery (A100n1) with energy.

Illustrated Driving mode just with the combustion engine

The power flow only takes place from the combustion engine onto the front and rear axle.

Illustrated: Driving mode just with the electrical machine 2 (A79/2)

The power flow only takes from the electric machine 2 on the front and rear axle.

The high voltage-battery supplies the electrical machine 2 with energy which then generates a torque and thus drives the vehicle.

Illustrated Acceleration mode

The power flow takes place from the combustion engine and one of the electrical machines to the front and rear axle.

The high voltage battery provides the electrical machine with energy which then generates a torque which operates on the drive to support the torque generated by the combustion engine.

Illustrated Brake mode (deceleration mode)

The power flow only takes place from the front and rear axle onto the electrical machines. The regenerative braking torque is converted by the electrical machine into electrical energy. The electrical machine operates as an alternator and charges the high voltage battery.
