<P>PROBLEM TO BE SOLVED: To enable a vehicle to run as much as possible, even if a decrease of an insulating resistance is detected. <P>SOLUTION: When a decrease in insulation resistance of a power system 25 is detected on the basis of an output from a voltage waveform output circuit 42, a portion of the decrease in insulation resistance is specified. If it is an auxiliary machine 34 rather than a relay 36, a system main relay 32 is turned on and the relay 36 is turned off, and an inverter 28 is driven to allow a vehicle to run based on the power from a motor 26. In this way, if the portion of the decrease in insulation resistance is not used for running of the vehicle; the vehicle can run, and convenience of a driver can be improved, compared to a control method of stopping the entire system irrespective of a portion of a decrease in insulation resistance. <P>COPYRIGHT: (C)2008,JPO&INPIT |
