    Abstract: PROBLEM TO BE SOLVED: To solve a problem that it may be impossible to effectively collect warm water in a heat storage system for an internal combustion engine.
    SOLUTION: When an ECU refers to a hysteresis of an accelerator opening, and determines that the accelerator opening (S10a) is small, it is supposed that a peak value and a mean value in the temperature of cooling water for the internal combustion engine are low, and lowers a warm water collection starting temperature from an initial value (S12). When it is supposed that the accelerator opening is in an average (S10b), a collection starting temperature is left to be the initial value (S14) as it is. When it is supposed that the acceleration opening is great (S10c), a warm water collection starting temperature is raised from the initial value (S16).

    Abstract: PROBLEM TO BE SOLVED: To provide electric power supply structure capable of effectively supplying electric power to a temperature raising device for an in-vehicle instrument. SOLUTION: The temperature raising device for the in-vehicle instrument makes an electric motor and an internal combustion engine 11 be drive sources, and is applied for a hybrid vehicle equipped with an inverter 17 with a converter which lowers output voltage of an HV battery 16 to DC14V and inputs it to an auxiliary machine and an auxiliary machine battery 23. When cooling water stored in a thermal storage tank 21 is supplied to the internal combustion engine 11 with an electric water pump 22 to raise the temperature of the engine 11, the water pump 22 is driven by the output voltage from the HV battery 16 lowered to DC14V through the inverter with the converter. When the cooling water is stored into the thermal storage tank 21 in accompany with the turning-off of an ignition switch, the water pump 22 is driven with DC12V from the auxiliary machine battery 23.

    Abstract: PROBLEM TO BE SOLVED: To avoid the situation of becoming in capable of restarting a driving force source after stopping the specific driving force source. SOLUTION: Before automatic stopping processing of an engine, determination is made on whether or not the engine can be restarted by a starter MG. When determining that the engine is in a condition that power generation is performed by the starter MG (YES in Step 110), power generation processing by the starter MG is performed (Step 110). Next, when determining that the power generation in normally performed by the starter MG (YES in Step 130), a starter MG normal flag exstmg is set to ON (Step 140). When determining that the power generation is not normally performed (NO in Step 130), the starter MG normal flag exstmg is set to OFF (Step 150). COPYRIGHT: (C)2004,JPO

    Abstract: PROBLEM TO BE SOLVED: To enable air-fuel ratio control which can make compatible both the reduction of NOx and the prevention of the generation of catalyst exhaust smell. SOLUTION: At the load operation of an engine for charging a battery during stopping, a target air-fuel ratio is made nearer to a rich side than a stoichiometric air-fuel ratio thereby carrying out the air-fuel ratio control (step S140), whereby an oxygen amount in a three-way catalyst is changed so as to be far from the generation condition of NOx, and the NOx in exhaust gas is reduced. Together with this, by carrying out the air-fuel control for a predetermined time of A second from a charge starting time (steps S130, S150), the generation of the catalyst exhaust smell due to the exhaustion of oxygen in the three-way catalyst can be prevented. Accordingly, in charging of the battery during stopping, the air-fuel ratio control which can make compatible both the reduction of NOx and the prevention of the generation of the catalyst exhaust smell is realized.

    Abstract: PROBLEM TO BE SOLVED: To provide a battery power distribution control device capable of smoothly performing the start of an engine by restricting the drive of an auxiliary unit in accordance with the residual capacity of power in the power supply of a vehicle. SOLUTION: The SOC, voltage, temperature, etc., of a battery are fed to a limit value calculation part 30, and the allowable battery output or battery voltage is grasped as the residual capacity of power of the battery. In accordance with the allowable battery output or battery voltage, the limit value calculation part 30 calculates the limit value of an oil pump motor 22, and the obtained value is fed to an oil pump motor control part 28. The oil pump motor control part 28 limits the torque or revolving speed of the oil pump motor 22 in accordance with the limit value. This allows securing the power supplied to a cranking motor 10, which allows the engine 12 to be started smoothly.

    Abstract: PROBLEM TO BE SOLVED: To provide an intake air quantity control device of an internal combustion engine which is an on-vehicle internal combustion engine furnished with a variable valve system and capable of more properly carrying out dashpot control at the time of decelerating a vehicle. SOLUTION: Starting time to damp (gradual decreasing operation) of intake air quantity secured for dashpot control, that is, dashpot quantity is normally set at total closing judgement time of a throttle valve. Hereby, damping of the dashpot quantity is started under a condition where a timing advance value becomes less than A deg.FR to eliminate residue of engine torque by monitoring the timing advance value of a variable valve system (variable valve timing mechanism) after total closing judgement of the throttle valve.

    Abstract: PROBLEM TO BE SOLVED: To provide an idling speed control valve for an internal combustion engine which can speedily converge the engine speed to a target value irrespective of abrupt or slow application of external load. SOLUTION: A steering 51 is operated at the time of idling an engine 1, and a power steering 52 is driven. An air amount is corrected, and supplied to the engine 1 through an idling speed control valve 41. The air is gradually corrected with a preset value serving as an upper limit guard value, so that the engine speed is kept as a target value. The upper limit guard value is set large when a variation rate of the engine speed sensed at the first time after starting the power steering 52 is large. The upper limit guard value is set small when the variation rate of the engine speed is small.
