Patent ID: 7372677

Claim:
A control apparatus for an internal combustion engine driven vehicle equipped with a power supply unit having an AC generator driven by an internal combustion engine for driving the vehicle, and a power converter which converts an output voltage from the AC generator into an AC voltage of a certain frequency, the apparatus comprising: a leakage detection device having leakage detection means for detecting occurrence of electric leakage in the power supply unit and leakage occurrence position identification means which determines whether an electric leakage has occurred in a circuit between the AC generator and the power converter or has occurred in a circuit on the output side of the power converter when the electric leakage is detected by the leakage detection means; and electric shock preventing control means for performing control for preventing electric shock on at least one of the internal combustion engine and the power converter according to the result of identification performed by the leakage occurrence position identification means, while allowing the rotational speed of the internal combustion engine to increase to a speed at which travel of the vehicle is enabled, when the leakage detection means detects the occurrence of electric leakage.
