Steuerungsvorrichtung für ein Fahrzeug, Steuerungsverfahren für ein Fahrzeug und Verfahen zum Schätzen einer Leistungsaufnahme eines Kühlventilators

摘要

Along with a rotational speed sensor being fitted to the crank shaft of an engine, a rotational speed sensor is fitted to a cooling fan; and the energy consumption of the cooling fan is estimated by using a map based upon an engine rotational speed (a pulley rotational speed Np) and a fan rotational speed Nf which have been detected by these rotational speed sensors. By controlling the operation of the engine based upon the energy consumption of the cooling fan which has been estimated in this manner, it is possible to control the operation of the engine more appropriately.
