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. |

1. A vehicle control device, comprising:
a smoothing capacitor; a first drive circuit; a second drive circuit; a control circuit; and a switch, wherein the vehicle control device controls an on-board device mounted a vehicle, wherein the on-board device includes
a rotating electrical machine, andan engaging/disengaging mechanism having a function to permit and cut off torque transmission between a driven body that is rotationally driven by the rotating electrical machine and the rotating electrical machine, wherein the smoothing capacitor smoothes electric power that is applied from a power supply mounted on the vehicle, wherein the first drive circuit drives the rotating electrical machine with the electric power smoothed by the smoothing capacitor, wherein the second drive circuit drives the engaging/disengaging mechanism with the electric power smoothed by the smoothing capacitor, wherein the control circuit controls the first drive circuit and the second drive circuit, wherein the switch has a function to connect and disconnect the first drive circuit and the second drive circuit to and from the power supply, and is provided closer to the power supply such that the smoothing capacitor is interposed between the switch and the first and second drive circuits, wherein if an abnormal condition of the vehicle having the on-board device mounted thereon is detected in a state where the drive circuits are connected to the power supply, the control circuit switches the switch to disconnect the drive circuits from the power supply and supplies electric power generated by charge stored in the smoothing capacitor to the engaging/disengaging mechanism via the second drive circuit. |
