<P>PROBLEM TO BE SOLVED: To secure the acceleration performance of a vehicle in an accelerator pedal pressing force control device of a hybrid vehicle, which makes the pressing force of the accelerator pedal larger than a base pressing force when the opening degree of the accelerator reaches a predetermined accelerator opening degree threshold or larger. <P>SOLUTION: A first accelerator opening degree is set, which is an accelerator opening degree for changing the mode from an EV mode in which a vehicle is driven only by a motor generator 2, to an HEV mode which drives an engine 1. If the accelerator opening degree exceeds the first accelerator opening degree, the pressing force of an accelerator pedal 32 is made larger than a base pressing force. The first accelerator opening degree is set to decrease as the SOC of a battery 9 decreases, and has a lower limit which is regulated by a second accelerator opening degree based on the accelerator opening degree which is the opening degree in equilibrium with a constant speed on a flat road. Thus, it is possible to depress the accelerator pedal 32 more than the fixed amount, ensuring the acceleration performance of the vehicle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
