Abstract

A vehicle control device includes a drive motor and an engaging/disengaging mechanism having a function to permit and cut off torque transmission between the drive motor and wheels. The vehicle control device further includes a smoothing capacitor that smoothes electric power applied from a secondary battery, a drive circuit for the drive motor, a drive circuit for the engaging/disengaging mechanism, and a microprocessor for controlling each drive circuit. If it is determined that a collision of a vehicle has occurred, the microprocessor disconnects each drive circuit from the secondary battery, and outputs a command to disengage the engaging/disengaging mechanism.
