VEHICLE HAVING A COMPONENT COOLED BY MEANS OF A COOLING AIR MASS FLOW

摘要

The invention relates to a vehicle having at least one component (K) which, for cooling purposes, is impinged on by a cooling air mass flow delivered by means of at least one delivery device such as a fan (L) or spoiler, for which cooling air mass flow a setpoint value is predetermined which, for an assumed maximum thermal loading of the at least one component (K), provides a cooling action adequate for the operation of said component, wherein a control device (S) is provided for controlling an intensity of the cooling air mass flow and is designed such that the cooling air mass flow is dimensioned, taking into consideration thermal demands of the component (K) at least in an upper driving speed range, such that a sum of a power consumption of the at least one component (K), of the at least one delivery device and of a fraction, allotted to the delivery of the cooling air mass flow, of a traction power of the vehicle is smaller than a sum of the power consumption of the at least one component (K), of the at least one delivery device and of a fraction, allotted to the delivery of the cooling air mass flow at the predetermined setpoint value thereof, of a traction power of the vehicle.
