<P>PROBLEM TO BE SOLVED: To solve the following problem: deviation occurs between the operation of an accelerator and change in the revolution of an internal combustion engine, and feeling of incompatibility is given to an occupant if maintaining the internal combustion engine in an idling driving state when a hybrid vehicle is traveling by a motor. <P>SOLUTION: This hybrid vehicle is provided with a motor for generating a driving force corresponding to traveling, and functioning as a generator; an internal combustion engine having a throttle valve to be opened and closed according to the manipulated variables of an accelerator for generating a driving force corresponding to traveling; a drive axle for transmitting the driving force to a driving wheel; a first transmission system for transmitting the driving force of the motor to the drive axle; a second transmission system equipped with a transmission and a joint device for transmitting the driving force of the internal combustion engine to the drive axle; a motor driving force control means for controlling the motor to output a driving force necessary for traveling; and a controlled variable setting means for setting the controlled variables of the throttle valve of the internal combustion engine based on the manipulated variables of the accelerator so that when this hybrid vehicle travels by controlling the driving force of the motor, the internal combustion engine is put in a no-load operating state in such a state that the joint device is connected. <P>COPYRIGHT: (C)2009,JPO&INPIT |
