Claim:
1. A vehicle controlling system comprising: a high-voltage circuit comprising a motor for driving a vehicle and a generator driven by an engine; an intermediate-voltage circuit comprising a battery and having a lower potential than the high-voltage circuit; a low-voltage circuit having a lower potential than the intermediate-voltage circuit, accessories being disposed to the low-voltage circuit; a transformer disposed between the high-voltage circuit and the intermediate-voltage circuit; a down converter disposed between the intermediate-voltage circuit and the low-voltage circuit; a generator controller to control the generator such that the generator generates power equal to or higher than a sum of power consumed by the motor and power output from the transformer to the intermediate-voltage circuit at a temperature of the battery lower than a predetermined temperature; and a transformer controller to control the transformer such that the transformer outputs power equal to or lower than power output from the down converter to the low-voltage circuit at a temperature of the battery lower than the predetermined temperature.
