PROBLEM TO BE SOLVED: To prevent waste of pump drive force simultaneously with improving also fuel consumption of an internal composition engine. SOLUTION: This vehicle is formed by connecting an engine 1 and an electric rotary drive source 26 provided with both functions of a motor and generator to a drive shaft 25 of a belt type continuously variable transmission 30 and connecting its output shaft 37 to a drive wheel 47 through a drive force transmitting system. In this vehicle, an electric motor-driven fluid pump 51 operated by drive rotating an electric motor is mounted. In this motor-driven fluid pump 51, supplying a shifting fluid pressure to the belt type continuously variable transmission 30, has a delivery capacity able to supply a lubricating fluid to each drive part. A control means performs control, when the vehicle performs steady running, outputting a drive signal of low rotation to the electric motor 50 to reduce a delivery amount of the motor-driven fluid pump 51, when the belt type continuously variable transmission 30 performs shift control, outputting a drive signal of high rotation to the electric motor 50 to increase the delivery amount of the motor-driven fluid pump 51. |
