Abstract: An electric motor radiator (34), a feeding mechanism (30), and a cooling oil circulation path (32) constitute a cooling mechanism that cools the electric motor (6) via an electric motor cooling oil that is a cooling medium. The electric motor radiator (34) forms a circulation path between the electric motor (6), and cooling of the electric motor (6) is performed via the electric motor cooling oil. A PCU radiator (44), a feeding mechanism (40) and a cooling water circulation path (42) constitute a cooling mechanism that cools a PCU (8) via a PCU cooling water that is a cooling medium. The PCU radiator (44) forms a circulation path between the PCU (8), and cooling of the PCU (8) is performed via the PCU cooling water. Further, the feeding mechanism (30, 40) operate by power received from a power storage portion (16).

Abstract: An ecorun ECU executes a program including the steps of: starting operation of an electric fan if an air-conditioner refrigerant pressure is higher than a pressure threshold value or an inverter coolant temperature is higher than a temperature threshold value and if the electric fan is not operating; restarting an engine by prohibiting temporary stop of the engine if the engine is not operating; and performing charging processing if SOC of a battery is lower than an SOC threshold value.

Abstract: 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.

Abstract: A vehicle which uses an internal combustion engine and a motor generator as drive sources is provided with a battery disposed under a seat and a fan for cooling the battery. Power is exchanged between the motor generator and battery via an inverter. An electronic control unit estimates the level of background noise which is noise other than the operating sound of the fan in the passenger compartment based on the vehicle speed and rotation speed, etc., of the internal combustion engine. Then, the electronic control unit calculates an operation command value for the fan based on the estimated background noise level and temperature level of the battery and controls the rotation speed of the fan through the operation command value. As a result, it is possible to effectively cool the battery while reducing sensible noise caused by the operating sound of the fan.
