Title:
COOLANT CIRCULATION SYSTEM FOR TRANSMISSION OIL, CONTROL METHOD, VEHICLE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/001097
Kind Code:
A1
Abstract:
A control method for a coolant circulation system for transmission oil, comprising: acquiring an actual oil temperature of a transmission, a clutch temperature, and an ambient temperature; calculating an equivalent oil temperature of the transmission; determining whether the equivalent oil temperature of the transmission is greater than a preset oil temperature; on the basis of the result of the determination that the equivalent oil temperature of the transmission is greater than the preset oil temperature, determining, according to the equivalent oil temperature of the transmission, a target temperature of an engine coolant and a target flow rate of coolant flowing through a transmission oil cooler; and controlling the engine coolant to change from a current temperature to the target temperature while controlling the flow rate of the coolant flowing through the transmission oil cooler to change from a current flow rate to the target flow rate. The present invention also relates to a coolant circulation system for transmission oil, a vehicle, and a storage medium.
