Vehicle drive system

A vehicle drive system includes a start request determination portion (202) determining whether a start of the engine (101) is requested when a vehicle drives using a motor (102) as the power source without using an engine (101), a start mode determination portion (201) comparing a rotation speed of...

Beschreibung
Zusammenfassung:	A vehicle drive system includes a start request determination portion (202) determining whether a start of the engine (101) is requested when a vehicle drives using a motor (102) as the power source without using an engine (101), a start mode determination portion (201) comparing a rotation speed of an input shaft detected by a rotation speed detection portion (140) and a predetermined engine start target rotation speed when the start of the engine (101) is requested and determining whether the rotation speed of the input shaft is assumed to be lower than the engine start target rotation speed, and an engine start control portion (211) disconnecting the motor (102) and the engine (101) from a driving shaft (120, 121a, 121 b) of the vehicle (100) to start the engine (101) by the motor (102) when the start of the engine (101) is requested and when the rotation speed of the input shaft is assumed to be lower than the engine start target rotation speed.
