Title: Control device for vehicle
Inventor: IKUSHIMA YOSHIHIRO
IPC: F16H57/04
Filed: 2019-09-04
Abstract: To provide a control device for vehicle that suppresses oil from being blown in a bank travel.SOLUTION: A control device for vehicle comprises a control part which drives an electric oil pump 36 on determining the vehicle 10 is traveling on a bank. Consequently, when it is determined that the vehicle 10 is traveling on the bank, the electric oil pump 36 is driven to send out oil in a case 18 so as to cool a motor 12, so oil reserved in the case 18 has a drop in oil level. Therefore, when the oil level of the oil reserved in the case 18 is inclined owing to the bank travel, the rotor 34 of the motor 12 which is rotating at a high speed in the case 18 and the oil reserved in the case 18 are suppressed from coming into contact with each other, so oil agitation by rotation of the rotor 34 of the motor 12 is suppressed, so that a large amount of oil mist or bubbles can be suppressed from being generated.SELECTED DRAWING: Figure 3
