Method for operating a cooling system for a hybrid electric vehicle comprising a liquid coolant delivery circuit

摘要

The present invention relates to a method of operating a cooling system 10 for a hybrid vehicle comprising at least one heat engine 12 and an electric motor 14, wherein the cooling system 10 The method of operation comprises at least the following steps:-determining whether the temperature of the liquid coolant in the high temperature cooling circuit 100 is lower or higher than the critical operating temperature TFmax of the low temperature cooling circuit 200 (E1); And-a transfer circuit connecting the high temperature cooling circuit 100 and the low temperature cooling circuit 200 to each other when the temperature of the liquid coolant in the high temperature cooling circuit 100 is lower than the critical operating temperature TFmax of the low temperature cooling circuit 200. And opening the control means 302 and 306 for controlling 300 (E2).
