Motor vehicle comprising a motor with an associated cooling water circuit and a separately electrically operable heating element for heating the passenger cell, as well as a method for the temperature management of a motor vehicle

摘要

Motor vehicle comprising a motor (4; 15) with an associated cooling water circuit (5; 11), which, via a heat exchanger (10; 16) heat for heating the passenger compartment can be extracted from, a separately electrically operable heating element (3; 20) for heating the passenger cell, as well as at least one control device for controlling the cooling water circuit (5; 11) and of the heating element operation, characterized in that the cooling water flow as a function of the following the start-up of the motor vehicle engine temperature rises, starting from a minimum flow rate at low engine temperature with increasing engine temperature to a maximum flow rate can be increased, while parallel for this purpose, the heat output of the heating element (3; 20), starting from a high heating power at low engine temperature with increasing engine temperature can be reduced to a minimum value, in such a way that the heat output of the heating element (3; 20) is slowly reduced in this manner, in which the cooling water flow is increased.
