Abstract

The invention relates to a fan system for a controllably cooling a vehicle internal combustion engine comprising an electric fan motor and a control unit for controlling said fan motor, wherein said control unit controls the fan motor according to a regulation correcting variable dependent on a desired cooling power, the control unit is constructed in such a way that it controls the fan motor independently of the desired cooling power at a determined moment with a regulation-correcting variable increased with respect to a correcting variable for a predetermined space of time.
