Patent ID: 7303504

Claim:
A power switchover apparatus for a hybrid vehicle, the hybrid vehicle including a starting clutch provided between a crankshaft of an engine and an automatic transmission, a one-way clutch interposed between the automatic transmission and a drive shaft, and a drive motor connected to the drive shaft, wherein, upon starting, the one-way clutch is controlled to idle using the motor as a power source, and thereafter, the one-way clutch is connected to switch over the power source to the engine, said power switchover apparatus for a hybrid vehicle comprising: target rotational speed setting means for setting a target rotational speed of the engine when the power source is to be switched over from the motor to the engine; and control means for controlling the engine rotational speed and the transmission ratio of the automatic transmission in response to the target rotational speed, said control means including: means for controlling the engine rotational speed to follow up the target rotational speed; and means for controlling the transmission ratio of the automatic transmission to rise until the power of the engine is transmitted to the drive shaft while the engine rotational speed remains following up the target rotational speed.
