Abstract:
A control device for a hybrid vehicle which comprises:an engine,a first electric motor connected to said engine,a second electric motor connected through a clutch to said engine,a transmission which transmits a motive force to a drive system and which is connected to said second electric motor,a microprocessor which is programmed to decide whether or not to connect said clutch on the basis of driving conditions, to detect a required motive force of said vehicle, and to limit an output of said engine to meet said required motive force, whereinsaid microprocessor is further programmed to control switching so as to control said engine so that an output of said engine outputs said required motive force when it is determined to connect said clutch,to control said first motor so that an output of said engine is kept at said required motive force and a rotation speed reaches a target rotation speed when it is determined to connect said clutch, andto control said clutch so that said clutch is connected after said engine rotation speed corresponds with a target rotation speed.
