The present invention relates to a cooling control device for an electric vehicle, which is provided with a first electric oil pump for supplying oil to a first motor for driving front wheels and a second electric oil pump for supplying oil to a second motor for driving rear wheels, and which is capable of switching between a four-wheel drive travel mode and a two-wheel drive travel mode using the second motor as a driving force source. The cooling control device for the electric vehicle drives only the second electric oil pump when the two-wheel drive travel mode is selected, and starts the operation of the first electric oil pump when it is predicted that the electric vehicle travels in the four-wheel drive travel mode.
本发明涉及电动车辆的冷却控制装置,所述电动车辆具备向驱动前轮的第一电机供给油的第一电动式油泵和向驱动后轮的第二电机供给油的第二电动式油泵,能够切换四轮驱动行驶模式和以第二电机为驱动力源的两轮驱动行驶模式,所述电动车辆的冷却控制装置在选择两轮驱动行驶模式的情况下,仅驱动第二电动式油泵,在预测出以四轮驱动行驶模式进行行驶的情况时,使第一电动式油泵开始工作。
