摘要：
A fan motor is controlled via a switching circuit from the moment when a cooling fan control routine is started until the moment when the rotational speed of the fan motor reaches a control-switching speed so that the higher the detected auxiliary battery voltage is when the cooling fan control is started, the lower the command duty ratio that is set. Accordingly, it is possible to activate the fan motor more reliably and to avoid generating excessive operating noise by the cooling fan when the fan motor is activated.
