A hybrid system, a hybrid vehicle, and a power method of communication of a hybrid system

Japanese Patent JP6197465

B2

PROBLEM TO BE SOLVED: To provide a hybrid system, a hybrid vehicle, and a power transmission method of hybrid system capable of suppressing large shock without reducing efficiency of electrical characteristic of a motor generator in immediately after connection and shortening the time for connection when a crank shaft and the motor generator are connected from a state that power transmission between them was disconnected by a power disconnection device.SOLUTION: A pulley ratio R of a CVT 16 is changed so that rotation number Nm of a motor generator 21 when power transmission between a crank shaft and the motor generator 21 is performed, is limited in a high efficiency rotation area by a clutch 17 for crank shaft, in advance. Thereby, rotation speed difference ΔN between first rotation number N1 transmitted from the crank shaft side on the clutch 17 for crank shaft and second rotation number N2 transmitted from the motor generator 21 side is reduced to a predetermined connection permission value N', then power transmission between the crank shaft and the motor generator 21 is performed by the clutch 17 for crank shaft.
