GF07.61-P-4015V ME Engine Torque Requirements Function







The function (torque interface) coordinates and prioritizes the requirements of all vehicle systems requiring torque. At the same time, the dynamics of the conversion for each requirement are established.

The engine torque is modified as follows:
- Increase or reduction of injected volume
- Early or late adjustment of the ignition angle (rapid)
- Combination of both options
If the injected volume is increased and the ignition angle simultaneously adjusted to "late", the engine torque first stays the same, but the option is available to rapidly achieve a subsequent torque increase by early adjustment of the ignition angle (torque reserve).

The following functions can require an engine torque:
- Driver preset
- Transmission control/protection
- ESP
- Cruise control/Distronic
- Torque limitation, e.g. during start-up
- Limitation of engine speed and max. speed
- Ancillary assemblies (coolant compressor, generator, power steering pump)
- Functions such as idle speed control and deceleration fuel shutoff.
