Document Type and Number:
WIPO Patent Application WO/2023/160637
Kind Code:
A1
Abstract:
A drive motor stalling cooling method for a vehicle. The vehicle (500) comprises a drive motor (501), an engine (502), an engine end oil pump (503) and a cooling flow path (504); the engine (502) is used for driving the engine end oil pump (503) to operate; the cooling flow path (504) is connected to the engine end oil pump (503) and the drive motor (501). The method comprises: if a driving mode of the vehicle (500) is a pure electric mode, the vehicle (500) satisfies a preset motor stalling activation condition, and the current temperature of the drive motor (501) is greater than the auxiliary cooling starting temperature of the engine, controlling the engine (502) of the vehicle (500) to be started, so that the engine end oil pump (503) of the vehicle (500) drives a coolant in the cooling flow path (504) to cool the drive motor (501).
