Abstract: PROBLEM TO BE SOLVED: To provide a warming-up apparatus of an internal combustion engine for appropriately avoiding a decrease in the recovery efficiency of a heating medium. SOLUTION: The warming-up apparatus of the internal combustion engine is applied to a hybrid vehicle for mounting a navigation system NS, thus supplying cooling water stored in a heat-storing tank 21 to the internal combustion engine 11 via an electric water pump 22, and hence promoting the warming-up of the internal combustion engine 11. When the current location of the hybrid vehicle in the navigation system NS arrives around a destination set to the navigation system NS, the cooling water that absorbs heat in the internal combustion engine 11 and becomes a high temperature is recovered into a heat-storing tank 21 through the electric water pump 22.

Abstract: PROBLEM TO BE SOLVED: To provide an engine accessory driving device of an internal combustion engine for enhancing the responsiveness of the internal combustion engine to the load request while driving an engine accessory. SOLUTION: One end of a drive shaft 25 of a compressor 24 is connected to one end of a connection shaft 27 of a motor 26, and a compressor pulley 22 is attached to the other end of the connection shaft 27. A belt 21 is stretched between the compressor pulley 22 and a crank pulley 20 of an engine 11. A one-way clutch mechanism is provided on the compressor pulley 22. When acceleration is requested to the engine 11, the rotational speed of a retainer to be rotated by the motor 26 is set to be higher than the rotational speed of a rotary yoke to be rotated by the engine 11 in the one-way clutch mechanism. The rotary yoke is idled with reference to the retainer, and the load to be transmitted from the compressor 24 to the engine 11 is cut off thereby. COPYRIGHT: (C)2004,JPO

Abstract: PROBLEM TO BE SOLVED: To improve failure determination precision of a thermostat, related to a technique for determining failure of a cooling system of an engine in which cooling water is supplied to an air conditioner.SOLUTION: When an estimated water temperature of the engine is equal to or higher than a first threshold (YES in S100), it is determined in S102 whether an actual water temperature of the engine detected by a temperature sensor is equal to or higher than a second threshold. When the actual water temperature is equal to or lower than the second threshold value (YES in S102), the amount of cooling water used by a heater of the air conditioner is reduced in S106. In S108, failure of the thermostat is determined using an actual water temperature detected after the amount of the cooling water used by the heater is reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a cooling control device for an internal combustion engine, capable of appropriately setting the operation time of an electric water pump for checking water temperature. SOLUTION: The cooling control device for the internal combustion engine cools by circulating the cooling water by the electric water pump. A heat quantity estimation means estimates the heat quantity of the internal combustion engine at the time of previous trip and an operation time changing means changes the operation time of the electric water pump for checking the temperature of the cooling water (water temperature check) on start-up based on the estimated heat quantity of the internal combustion engine. For example, the smaller the heat quantity is, the shorter the operation time is set. Thus, the operation time of the electric water pump for checking the water temperature on start-up can be appropriately shortened. Hence, wasteful operation of the electric water pump can be suppressed, power consumption can be reduced and thermal diffusion can be prevented. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a hybrid vehicle control device having improved fuel economy by actualizing early transit to intermittent operation. SOLUTION: The hybrid vehicle control device includes a control means for setting the difference between the generated torque of an engine found in accordance with a detection signal from a combustion pressure sensor and the actual torque of the engine found in accordance with the output torque of a generator as friction torque to correct the amount of intake air to be sucked into the engine according to the friction torque. In this way, it uses an accurate value instead of a speculative value for the friction torque to correct the amount of intake air. Thus, the learning of the amount of intake air can be finished earlier, as compared with the case of using the speculative value for the friction torque to correct the amount of intake air, resulting in improved fuel consumption by actualizing early transit to intermittent operation.
