The present invention relates to a cooling control device for an electric vehicle, which prevents or suppresses air suction during rapid acceleration and deceleration of an oil pump for cooling a motor for driving. The first oil pump supplies oil to the first motor for the front wheel. A second oil pump for supplying oil to the second motor for the rear wheel; and a controller (31) that controls the first oil pump and the second oil pump, the controller (31) being provided with: a detection unit (31a) that detects at least one of acceleration and deceleration when traveling by operating the first motor and the second motor; a sudden acceleration/deceleration determination unit (31b) that determines that either the acceleration or deceleration detected by the detection unit (31a) exceeds a predetermined threshold value; and a reduction control unit (31c) that, when it is determined that either the acceleration or the deceleration exceeds a predetermined threshold value, performs control so as to reduce the amount of oil supplied by an oil pump that supplies oil to one of the first motor and the second motor having a smaller load.
本发明涉及防止或抑制对行驶用的电机进行冷却的油泵在急加减速时吸入空气的电动车辆的冷却控制装置。具备:第一油泵,向前轮用第一电机供给油;第二油泵,向后轮用第二电机供给油;控制器(31),控制第一油泵和第二油泵,控制器(31)具备:检测部(31a),检测使第一电机及第二电机动作而行驶时的加速度和减速度中的至少任一方;急加减速判定部(31b),判定由检测部(31a)检测出的加速度和减速度中的任一方超过预先确定的阈值;以及降低控制部(31c),在判定为加速度和减速度中的任一方超过预先确定的阈值的情况下,进行使基于向第一电机和第二电机中的负荷小的一方的电机供给油的油泵的油的供给量降低的控制。
