THERMAL MANAGEMENT SYSTEM CONTROL METHOD FOR HYBRID VEHICLE, AND HYBRID VEHICLE

WIPO Patent Application WO/2024/066110

A1

A thermal management system control method for a hybrid vehicle, and a hybrid vehicle. The thermal management system control method for a hybrid vehicle comprises: entering a heat storage mode when the temperature of engine coolant is higher than a highest temperature limit, wherein the heat storage mode is that an outlet of a coolant pipeline of an engine (1) is communicated with a liquid inlet of a heat accumulator (6), and a liquid outlet of the heat accumulator (6) is communicated with an inlet of the coolant pipeline of the engine (1), so that the heat accumulator (6) reduces the temperature rise of the engine coolant while storing heat; and when the engine (1) stops, enabling the engine (1) to enter an engine stop cycle mode, wherein the engine stop cycle mode is that the engine coolant is driven by a first pump (5) to circularly flow between the coolant pipeline of the engine (1) and an engine radiator (2).
