Abstract: A cooling apparatus of vehicle driving apparatuses of the invention controls flow of cooling water so as to cool engine cooling water by at least two radiators when a requested ability of cooling an internal combustion engine, is equal to or larger than a requested ability of cooling a hybrid device. The number of the radiators used for cooling the engine cooling water is larger than the number of the remaining radiator(s). The cooling apparatus controls the flow of the cooling water so as to cool device cooling water at least two radiators when the requested ability of cooling the hybrid device, is larger than the requested ability of cooling the internal combustion engine. The number of the radiators used for cooling the device cooling water is larger than the number of the remaining radiator(s).

Abstract: A vehicle-mounted temperature controller 100 provided with a compressor 2 having a compression part 2a compressing a refrigerant and a drive motor 2b driving the compression part 2a and using waste heat accompanying driving of the compression part 2a to make the temperature of the refrigerant rise, a blower 61 blowing air to a heater core 145 raised in temperature by receiving heat of the refrigerant and blowing air exchanged in heat with the heater core 145 to the inside of the passenger compartment, and an electronic control unit 51 controlling a current phase of the drive motor 2b to a phase by which a ratio of change of an output of the drive motor 2b to a change of the current phase becomes relatively larger to thereby drive the drive motor 2b by an inefficient drive operation when the blower 61 is in a nondriven state and controlling the current phase to a phase by which a ratio of change of an output of the drive motor 2b to a change of the current phase becomes relatively smaller to thereby drive the drive motor 2b by an inefficiently drive operation when the blower 61 is in a driven state.

Abstract: A cooling system for a hybrid vehicle that cools cooling medium for an air conditioner without reducing a driving performance, irrespective of a running condition. A detector detects data relating to operating conditions of a high-current device cooling circuit, a supercharger cooling circuit, a high-current device, an engine, a supercharger, and the hybrid vehicle. A controller selects one of a first water passage and a second water passage by manipulating a control valve based on the data collected by the detector, in such a manner as to maximize an amount of heat transferred from the cooling medium to high-current device cooling water or supercharger cooling water.

Abstract: A cooling apparatus of a vehicle driving system of the invention connects an engine water circulation passage to a hybrid system water circulation passage and flows cooling water in the engine water circulation passage and the hybrid system water circulation passage to cool a first hybrid system component by the cooling water cooled by an engine radiator and cool a second hybrid system component by the cooling water cooled by a hybrid system radiator when an engine cooling process is not requested, a first hybrid system cooling process is requested, a second hybrid system cooling process is requested, and a connection condition is satisfied. The connection condition is satisfied when the engine cooling process is not requested, and the cooling water flowing into the hybrid system water circulation passage from the engine water circulation passage, can cool the first hybrid system component.

Abstract: A cooling apparatus of a vehicle driving system for driving a vehicle according to the invention activates a heat pump to cool a hybrid system by cooling medium and flows an engine cooling water in an engine water circulation passage through a condenser to cool the cooling medium by the engine cooling water at the condenser when an engine water circulation condition is satisfied. The engine water circulation condition is a condition that a heat pump activation condition is satisfied, and an engine cooling condition is not satisfied. The heat pump activation condition is a condition that a process of cooling the hybrid system by the cooling medium of the heat pump is requested. The engine cooling condition is a condition that a process of cooling an internal combustion engine by the engine cooling water is requested.
