To prevent or suppress air intake by an oil pump that cools a motor for travel during rapid acceleration or deceleration.SOLUTION: A cooling control device for an electric vehicle includes: a first oil pump that supplies oil to a first motor for front wheel; a second oil pump that supplies oil to a second motor for rear wheel; and a controller 31 that controls the first oil pump and the second oil pump. The controller 31 comprises: a detection unit 31a that detects at least one of the acceleration or deceleration of a vehicle while the first motor and the second motor are operated and the vehicle is travelling; a rapid acceleration/deceleration determination unit 31b that determines if one of the acceleration and deceleration detected by the detection unit 31a exceeds a predefined threshold; and a reduction control unit 31c that performs control of reducing a supply amount of the oil by the oil pump that supplies the oil to the motor with the smaller load in the first motor and the second motor when it is determined that one of the acceleration and deceleration exceeds the predefined threshold.SELECTED DRAWING: Figure 5

    【課題】走行用のモータを冷却するオイルポンプが、急加減速時に空気を吸い込むことを防止もしくは抑制する。【解決手段】前輪用第1モータにオイルを供給する第1オイルポンプと、後輪用第2モータにオイルを供給する第2オイルポンプと、第1オイルポンプと第2オイルポンプとを制御するコントローラ31を備え、コントローラ31は、第1モータおよび第2モータを動作させて走行している際の加速度および減速度の少なくともいずれか一方を検出する検出部31aと、検出部31aで検出された加速度と減速度とのいずれか一方が予め定めた閾値を超えていることを判定する急加減速判定部31bと、加速度と減速度とのいずれか一方が予め定めた閾値を超えていることが判定された場合に、第1モータと第2モータとのうち負荷の小さい方のモータにオイルを供給するオイルポンプによるオイルの供給量を低下させる制御を行う低減制御部31cとを備えている。【選択図】図5
