Abstract: PROBLEM TO BE SOLVED: To actualize smooth engine start in a vehicle on which an internal combustion engine is mounted with an cylinder injector and an intake passage injector and in which engine intermittent operation is controlled, while preventing the worsening of the nature of exhaust gas. SOLUTION: When the operation of the vehicle is finished, a solenoid relief valve 210 is operated (opened) and the operation of a low pressure fuel pump 180 is stopped to lower fuel pressure in a high pressure delivery pipe 130 and a low pressure delivery pipe 160, thus preventing the worsening of the nature of exhaust gas during next engine start, resulting from the leakage of fuel due to poor oil tightness in the injectors 110, 120 during stopping the operation. On the contrary, when the engine is temporarily stopped with the control of the engine intermittent operation, the low pressure fuel pump 180 is stopped while the operation (opening) of the solenoid relief valve 210 is prohibited. When the engine is restarted after temporarily stopped, quick engine start is actualized by injecting fuel into the high pressure delivery pipe 130 in which fuel pressure is secured, considering that the engine has temperature rise.

Abstract: PROBLEM TO BE SOLVED: To promptly output power based on demands of a driver while suppressing vibration upon starting of an internal combustion engine.
SOLUTION: When automatically starting an engine, upon a normal engine start, the amount of intake air is reduced by tightening the opening of a throttle valve (S140). When the driver presses down hard on the accelerator pedal, and an engine request power Pe* is a threshold value Pref or more, the throttle valve opening is an opening according to the request engine power Pe* (normal opening) and the amount of intake air is an amount corresponding to the engine demand power Pe* (S150). Cranking is performed to start the engine. Thereby, on a normal start of the engine, vibration at initial explosion can be suppressed, and when the requested engine power Pe* is large, driving power from the engine can be promptly outputted.

Abstract: PROBLEM TO BE SOLVED: To make the control simple even when there are a plurality of elements which should be prepared for starting up an internal combustion engine. SOLUTION: A delay time Tset in a normal state is set to a predetermined time Ts1 based on an engine coolant temperature Tw and a state of an air conditioner switch. The predetermined time Tsl is determined based on a time necessary for completing preheating of an engine 22 by a preheating device, preparations of sensors such as an air/fuel ratio sensor, and warming-up of an exhaust gas clean-up device (S100, S110). When it is determined that the vehicle can run using a motor based on a required torque Td*, a required power P* and the remaining capacity (SOC) of a battery (S120 to S150); the engine is started after the delay time Tset has elapsed. As a result, it is possible to efficiently perform start of the engine and operation immediately after the engine starts, and to make control at the time of starting the engine simple compared with the case where the engine is started after making determinations as to whether various preparations have been completed.

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 prevent lowering of heater performance during stopping of an internal combustion engine, in a vehicle such as a hybrid automobile wherein the internal combustion engine is temporary stopped.
SOLUTION: If a heater is in operation (Y of S10), ECU determines whether the internal combustion engine stops (S12). When the internal combustion engine is stopped (Y of S12), the ECU confirms that the temperature of cooling water is not less than a specified value (Y of S14), and compares the temperature of the cooling water with the temperature of hot water in a thermal storage tank. When the temperature of the hot water in the thermal storage tank is higher than that of the cooling water (Y of S16), the ECU controls a three-way switching valve to supply the hot water in the thermal storage tank to the heater (S18).
