Abstract
A hybrid vehicle provided with an engine, a first motor generator, a planetary gear mechanism, a second motor generator, a battery, a battery state sensing unit which senses the voltage and the residual capacity of the battery, a steepness sensor which senses the uphill steepness, an accelerator pedal depression amount sensor, and a controller. The minimum rotation speed of the engine is set in accordance with the uphill steepness and the accelerator pedal depression amount, when the hybrid vehicle is travelling in reverse and the battery is charged with the voltage of the battery equal to or below a first threshold or the residual capacity of the battery equal to or below a second threshold.
