Abstract: An electrical storage system includes an electrical storage device, a voltage sensor, a current sensor and a controller. The controller calculates a full charge capacity of the electrical storage device on the basis of a state of charge of the electrical storage device at the time when external charging is started, a state of charge of the electrical storage device at the time when the external charging is completed, and an accumulated value of a current value during the period when the external charging is being carried out, and sets a polarization elimination time. When a stopped time during the period when charging or discharging of the electrical storage device is stopped is longer than the polarization elimination time, the controller regards a voltage value of the electrical storage device at the time of at least one of the start of the external charging or the completion of the external charging as an open circuit voltage of the electrical storage device. The controller calculates a state of charge corresponding to the voltage value as a state of charge that is used to calculate the full charge capacity by using a correlation between the open circuit voltage and the state of charge. The controller shortens the polarization elimination time as a rate of change increases. The rate of change indicates a ratio of a variation in the open circuit voltage to a variation in the state of charge.

Abstract: A target cylinder (#3) is selected while an internal combustion engine (10) is operating in a steady state. The fuel injection quantity of the target cylinder (#3) is gradually increased or decreased and the fuel injection quantity of another cylinder (#1, #2, #4) is decreased or increased a corresponding amount in an inverse manner such that the overall air-fuel ratio of the internal combustion engine (10) does not change. During this time, the hydrogen content in exhaust gas is detected and the injection ratio when the hydrogen content is lowest is stored as an optimal injection ratio for each cylinder. Thereafter, fuel is injected into each cylinder at the optimal injection ratio for each cylinder.

Abstract: Heat generation amount PV k (Θ) is calculated with the use of cylinder pressure P(θ), detected by a cylinder pressure sensor, cylinder volume V(θ), and specific heat ratio K (steps 100 to 102). A crank angle O fix , at which the value of PV K (Θ) peaks, is determined as a start crank angle, at which an adiabatic process after combustion starts (step 104). A correction coefficient K fix is calculated based on the variation of the value of PV K (Θ) after Q fix (step 106). An actual heat generation amount PV k fiχ (θ) is calculated with the use of the correction coefficient K fix (step 110). A cooling loss coefficient K cool that determines a correlation between the cooling loss and crank angles may be calculated based on a water temperature and an engine speed and the actual heat generation amount PVC k fix (θ) may be made to reflect the cooling loss coefficient K cool .

Abstract: An ECU (52) performs atmospheric learning to correct an individual difference in an A/F sensor (46). In this case, when reducing fuel has been added before a fuel cut, the ECU (52) calculates, at fixed intervals, the total amount (A) of reducing fuel added and the total amount (B) of oxygen flowing through an exhaust passage (18). The ECU (52) then estimates the remaining amount (C) of reducing fuel remaining in the exhaust passage (18) using these total amounts (A, B), and performs atmospheric learning when the remaining amount (C) is equal to or less than an allowable value (F). As a result, atmospheric learning can be accurately performed at the earliest possible timing even if the timing at which the reducing fuel is added or the operating state of an internal combustion engine (10) or the like changes.

Abstract: When power begins to be supplied to a heater, open loop control is selected as the power supply control method to supply a predetermined power to the heater. After that, the control method is switched to feedback control to set the power to be supplied to the heater based on the difference between the target temperature and the actual temperature of the sensor chip if a predetermined period of time in which the difference between the target temperature and the actual temperature is expected to fall within a predetermined reference difference has passed since power began to be supplied to the heater.

Abstract: When it is predicted that the engine is going to be started in the near future, a heater portion of an air flow meter is energized so as to be heated in advance (step 106). Prior to the pre-heating, the intake air temperature TAFM is sensed by a temperature sensing portion of the air flow meter (step 104). After completion of start-up of an intake air temperature sensor, a difference between the intake air temperature TA sensed by the intake air temperature sensor and the previously sensed intake air temperature TAFM is obtained. When the difference is above a predetermined value, it is judged that the intake air temperature sensor or the air flow meter is in an abnormal condition (step 114).

Abstract: [PROBLEM] In setting of an upper limit voltage value to which discharge of an electric storage apparatus is allowed and an upper limit voltage value to which charge of the apparatus is allowed, deterioration of the apparatus is taken into account. [SOLVING MEANS] A reference voltage value is calculated by using a current value at present, a voltage value at present, and an internal resistance value at present of an electric storage apparatus. A dischargeable electric power (TWout) is calculated by using the reference voltage value and a predetermined internal resistance value (R_old) previously set to be higher than the internal resistance value at present (R_now). The dischargeable electric power is set as an allowable discharge electric power (Wout) when temporarily increasing the discharge electric power required of the electric storage apparatus. The reference voltage value is calculated from the internal resistance value at present and is a fixed value regardless of the relationship between the current value and the voltage value. Thus, the dischargeable electric power is also constant. Since the predetermined internal resistance value is higher than the internal resistance value at present, the dischargeable electric power can be set while the deterioration of the electric storage apparatus is taken into account.
