(57) [Problem] To provide a clutch for intermittently connecting an output shaft of an engine and an input shaft of a transmission, a rotating electric machine serving also as a motor and a generator, and connecting an input / output shaft of the rotating electric machine and an input shaft of the transmission. In a vehicle hybrid system including a gear transmission mechanism and a power storage device that stores power from a rotating electric machine, a clutch can be connected without a shock when starting power generation control when the engine is stopped in an operating state. When a connection request for a clutch is generated when the engine is stopped while the engine is in operation, the rotation speed of the rotary electric machine is set to a target value during a period from a neutral set of the transmission to a connection of the clutch. A means for controlling the speed (centered at S5 and S6), and a means for controlling the clutch 3 to be connected when the rotation difference between the rotation speed of the rotary electric machine 4 and the rotation speed of the engine 1 converges to a predetermined range (S7, S7). S8 Is the center). |
