Driving With Internal Combustion Engine And Electric Motor
Normal Driving
In "normal operation" the combustion engine drives the vehicle. The Electro-Drive Drive Motor -V141- works as a generator in that it charges the Hybrid Battery -A38- and provides power to the 12V vehicle electrical system. If the Hybrid Battery -A38- is charged sufficiently, the Electro-Drive Drive Motor -V141- can be switched on to drive the vehicle (boost).
Full Acceleration (Boost)
For full acceleration, the vehicle is driven by both the combustion engine and the Electro-Drive Drive Motor -V141-. This occurs automatically under the following conditions:
- Kick-down in "D"
- Pressing the accelerator pedal all the way down when the selector lever position is in "S"
- Pressing the accelerator pedal all the way down when the selector lever is in the Tiptronic gate
Decelerating or Braking
Depending on the brake pedal travel, the Electro-Drive Drive Motor -V141- and/or the brake pedal slows down the vehicle. The Electro-Drive Drive Motor -V141- only slows down when the brake pedal is in its "idle" position. The wheels drive the Electro-Drive Drive Motor -V141-, which acts as a generator in this case and captures the energy. The Hybrid Battery -A38- stores the gained energy and uses it again later. If the brake "idle position" is exceeded, then both the Electro-Drive Drive Motor -V141- and the brakes are used to slow down the vehicle.
