<P>PROBLEM TO BE SOLVED: To provide a vehicle control device for detecting an erroneous detection of an earth fault. <P>SOLUTION: The vehicle control device includes: a power converter 105 for converting power supplied through a pantograph 100 into drive power of a running vehicle; a contactor 104 connected between the power converter 105 and the pantograph 100, and interrupting power supplied from the pantograph 100; a current detector 107 connected between a housing of the power converter 105 and a ground point 108 attached to the housing, and detecting a current; and a current detector failure detecting means 1000 for flowing a simulation current in a current detector operation confirming circuit 109 connected to the current detector 107. The current detector failure detecting means opens or closes the contactor 104 based on a result of the current detector failure detecting means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
