Abstract
In a vehicle incorporating a control device connected to a solar battery, a storage battery, an operation unit and a ventilation unit, a preliminary ventilating device is set to either of charging mode in which the storage battery is charged from the solar battery, forced exhaust mode in which the ventilation unit is driven by power supplied from the storage battery, and in parking ventilating mode in which the ventilation unit is driven by an electromotive force supplied from the solar battery. Charging of the storage battery from the solar battery is possible even when the charging is controlled on the basis of the results of the measurement of the open-circuit voltage of the solar battery. When the solar battery exhibiting a voltage current curve lower than the reference curve is used, the ventilating fan can be activated before the amount of sunlight received by the solar battery has been maximized.
