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).

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).

Abstract: PROBLEM TO BE SOLVED: To accurately determine an abnormality that an air-fuel ratio differs among cylinders.SOLUTION: When determining whether the air-fuel ratio differs among the plurality of cylinders, a fluctuation amount of an output shaft rotational speed of an internal combustion engine is increased by, for example, retarding ignition timing, returning exhaust gas into a cylinder, or leaning the air-fuel ratio of each cylinder. Based on the increased fluctuation amount, the air-fuel ratio is determined whether it differs among the cylinders. The abnormality that the air-fuel ratio differs among the cylinders is detected by the fact that the fluctuation amount of the output shaft rotational speed is above a threshold.

Abstract: PROBLEM TO BE SOLVED: To provide a control apparatus for a vehicle that shortens the actuation delay time of a heater blower by stabilizing the cooling water temperature in a short time after the circulation of cooling water is started by a heating request.
SOLUTION: The control device for vehicle is mounted on a hybrid vehicle and provided with an electric water pump, a heater core, a heater blower, and control means. The electric water pump causes cooling water to circulate in an internal combustion engine. The heater core exchanges heat between the cooling water and the air. The heater blower causes the air heat-exchanged with the cooling water by the heater core to flow to the cabin. The control means actuates the electric water pump when a heating request is made based on an operation by an occupant and also actuates the heater blower with a predetermined delay time after the actuation of the electric water pump. The control means temporarily increases the output of the electric water pump during the period from the time of the heating request to the actuation of the heater blower and decreases the output of the electric water pump after the actuation of the heater blower.
