BMW 3: Operating principle
If the driver adjusts a desired temperature at the IHKA controls, the IHKA
calculates a corresponding
nominal temperature and compares it to the actual output temperature of the
electrical heating.
There is a coolant temperature sensor at the electrical heating output for this
purpose. This way the
IHKA control unit can decide whether the heat from the combustion engine is
sufficient to heat the
passenger compartment or whether the electrical heating should be switched on.
If the temperature
of the coolant is too low, the electric heating can heat up to a total of 6
stages. The electrical heating is
always condition-based thanks to this control operation.

When the coolant temperature is low, for example after driving off, or in
all-electric driving, the electric
changeover valve is activated by the Body Domain Controller (BDC). The

The brake booster is operated via the driver's foot operation, and the brake
actuation is determined by
means of the brake pedal angle sensor.
Depending on the brake pedal angle sensor signal, the valves in the Dynamic
Stability Control (DSC)
are switched so that
