To adjust the temperature of oil to an appropriate temperature when a vehicle is stopped.SOLUTION: A control apparatus for a vehicle includes: an electric oil pump for discharging oil which is used to cool an electric motor and lubricate gears; an electric water pump for discharging cooling water; a water cooling type oil cooler for exchanging heat between the oil and the cooling water; and a controller for controlling the output of the electric oil pump and the output of the electric water pump. While the vehicle is stopped (Step S1: Yes), when there is satisfied a first condition that the temperature of the oil is higher than a threshold (Step S2: Yes), and the temperature of the oil is equal to or lower than the temperature of the cooling water (Step S3: No), or when there is satisfied a second condition that the temperature of the oil is equal to or lower than the threshold (Step S2: No), and the temperature of the oil is equal to or higher than the temperature of the cooling water (Step S6: No), the controller stops at least one of the electric oil pump and the electric water pump (Steps S5 and S8).SELECTED DRAWING: Figure 3
【課題】車両が停車した際にオイルの温度を適切な温度に調整すること。【解決手段】電動機を冷却し、かつギヤを潤滑するためのオイルを吐出する電動オイルポンプと、冷却水を吐出する電動ウォータポンプと、オイルと冷却水との間で熱交換を行う水冷式オイルクーラと、電動オイルポンプの出力および電動ウォータポンプの出力を制御する制御部と、を備える車両の制御装置であって、制御部は、車両が停車中(ステップS1:Yes)には、オイルの温度が閾値よりも高く(ステップS2:Yes)かつオイルの温度が冷却水の温度以下(ステップS3:No)であることが成立する第1条件成立時、または、オイルの温度が閾値以下であり(ステップS2:No)かつオイルの温度が冷却水の温度以上(ステップS6:No)であることが成立する第2条件成立時に、電動オイルポンプおよび前記電動ウォータポンプのうちの少なくとも一つを停止する(ステップS5、S8)。【選択図】図3
