  • Alternating voltage output apparatus and vehicle including such alternating voltage output apparatus
    Patent number: 7265455
    Abstract: A control device controls first and second inverters such that alternating voltage is generated across neutral points of first and second motor generators. When the value of a signal representative of the remaining amount of fuel in a fuel tank becomes lower than a predetermined threshold value, the control device controls the first and second inverters such that the voltage level of the alternating voltage is changed in order to notify a user external to the vehicle of the low remaining amount of fuel.
    Type: Grant
