PROBLEM TO BE SOLVED: To provide a vehicle controller capable of securing vehicle traveling performance while improving protection of a battery and a connection device.SOLUTION: A vehicle driving motor 1 and a motor 2 driven by an engine 11 are arranged in a high-voltage circuit 6, a vehicle driving battery 3 is disposed in an intermediate-voltage circuit 7 of a potential lower than that of the high-voltage circuit 6, and a transformer 4 is provided between the high-voltage circuit 6 and the intermediate-voltage circuit 7. A heater 16 operated by power from the high-voltage circuit 6 to increase the temperature of the battery 3 is included in the battery 3. A fan 18 for supplying cooling air to the heater 16 is included in the battery 3. Further, a cooling air control unit 9F is provided to operate the fan 18 when the temperature T of the heater 16 is equal to or higher than a first predetermined temperature T.SELECTED DRAWING: Figure 1 |
