Title:
CONTROL METHOD FOR POWER ASSEMBLY HEAT EXCHANGE SYSTEM, POWER ASSEMBLY HEAT EXCHANGE SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/007361
Kind Code:
A1
Abstract:
A control method for a power assembly heat exchange system, a power assembly heat exchange system, and a vehicle. The power assembly heat exchange system comprises: a power assembly, a heat exchange pump, and a heat exchanger. The control method comprises the following steps: starting the heat exchange pump; determining the temperature of the power assembly and, on the basis of the temperature of the power assembly, generating a first signal for controlling the speed of the heat exchange pump; determining the speed of rotation of the power assembly and, on the basis of the speed of rotation of the power assembly, generating a second signal for controlling the speed of the heat exchange pump; and selecting the speed of the heat exchange pump: comparing the speed of the heat exchange pump corresponding to the first signal with the speed of the heat exchange pump corresponding to the second signal, and operating the heat exchange pump at the higher of the two speeds.
