ABSTRACT:
A fuel use limiter-equipped hybrid electric car has a battery unit chargeable by an external charger, an electric drive motor capable of driving wheels by electric power from the battery unit, an internal combustion engine for driving a generator to supply electric power to the electric drive motor, and a controller for controlling operations of the electric drive motor and internal combustion engine. The hybrid electric car is further provided with a fuel-use-state detector for detecting a change in a parameter, which change corresponds to a quantity of fuel used by the internal combustion engine since charging of the battery unit by the external charger. The controller limits at least one of an output of the electric drive motor and that of internal combustion engine when from results of a detection by the fuel-use-state detector, the change in the parameter is found to have reached a predetermined value.
