Vehicle engine temperature control method, device, equipment, storage medium and product

The invention relates to the technical field of vehicle engines, in particular to a vehicle engine temperature control method and device, equipment, a storage medium and a product. The method comprises the following steps: determining a required cooling water temperature according to power system information, vehicle state information and engine compartment heat management information; according to the difference value between the required cooling water temperature and the current engine water temperature, the target duty ratio of the thermostat is determined; and the current duty ratio of the thermostat is adjusted to the target duty ratio. According to the method, the power system information, the vehicle state information and the engine compartment heat management information are comprehensively analyzed, the required cooling water temperature is accurately determined, the target duty ratio of the thermostat is dynamically adjusted, and therefore accurate control over the engine temperature is achieved, an
