Abstract
A hybrid vehicle in which an engine can always be driven in a highly efficient region in accordance with the required running load. An engine torque of a combustion engine 2, in which an efficiency characteristic can be selected from those in a lean state and in a stoichiometric state, and a motor torque of a generator/motor 3 are transmitted to a driving output system as a driving torque. The combustion engine 2 is always operated in the most efficient state in each efficiency characteristic which is selected, and a vehicle control device 10 adjusts the motor torque by controlling the generator/motor 3 in accordance with the degree an accelerator opens, selects an efficiency characteristic in accordance with the required running load based upon the required running load input by a required running load detecting means, and amends the engine torque variance which is generated when the efficiency characteristic changes with the motor torque.
