The Controller determines the demand value for the fan's revolution rate depending on the engine load. It increases the fan's revolution rate during an engine braking phase and reduces it after the end of the engine braking phase. The revolution rate after the engine braking phase can be reduced to a lower value than that prior to the engine braking phase. <??>AN Independent claim is also included for the following: a method for controlling or regulating the revolution rate of a cooling fan motor for a heat exchanger of a motor vehicle engine. |
