In a vehicle incorporating a control device connected to a solar battery, a storage battery, an operation unit, a first ventilating fan 3 and a second ventilating fan 4, when the operation mode is set by a change-over operation of the operation unit 2 to a parking ventilation mode in which the first and second ventilating fans 3 and 4 are driven by supply of an electromotive force of the solar battery 6, a voltage and a current from the electromotive force of the solar battery 6 are gradually increased and continuously applied to the fan to perform gradual activation of the first ventilating fan 3. Thereafter, a switch unit 26 is closed, and the voltage and the current from the electromotive force of the solar battery are thereby simultaneously applied to the second ventilating fan 4, thus completing activation of the first and second ventilating fans.
