Abstract:
1. A hybrid vehicle comprising: an engine for driving primary driving wheels via a transmission, the engine being able to be suspended from combustion; a primary motor disposed between the engine and the transmission; a secondary motor for driving one of the primary driving wheels and secondary driving wheels which are different from the primary driving wheels; and an electricity storage unit connected to the primary and secondary motors, wherein the vehicle is driven by the secondary motor while allowing the primary motor to perform a combustion suspended idle operation wherein the combustion suspended idle operation comprises the primary motor rotating the engine according to driving conditions of the vehicle while combustion within cylinders in the engine is suspended; wherein a rotational speed of the primary motor, which is performing the combustion suspended idle operation, is maintained at a rotational speed which can provide minimum friction on the engine and which can generate a predetermined oil pressure; and wherein at least either an inlet valve or an exhaust valve is held closed during the combustion suspended idle operation by the predetermined oil pressure.
