Hybrid vehicle driving device

摘要

Object
To provide a hybrid vehicle driving device capable of executing electric power regeneration using only a rotational speed range where the electric power generation efficiency is high. Constitution
In the hybrid vehicle driving device including an engine drive system transmitting a drive force of an engine (7) to a transmission (17) through a one-way clutch (14) and transmitting a drive force after shifting by the transmission (17) to a rear wheel (WR) and a motor drive system transmitting a drive force of a motor (15) to the rear wheel (WR), the drive force of the motor 15 of the motor drive system is joined to a point upstream the transmission (17) and downstream the one-way clutch (14) in the engine drive system. The transmission (17) is provided with a twin clutch (18) capable of shifting between neighboring shift gears by alternately switching the connection state of a clutch (CL1) on one side and a clutch (CL2) on the other side, and is automatically shifted so as to produce an optional rotational speed and motor torque at which the electric power generation efficiency becomes high at the time of regeneration control of the motor (15).
