    Abstract: PROBLEM TO BE SOLVED: To prevent wrong determination of a misfire or the like according to the ion current detection result by limiting the combustion state determination of an internal combustion engine based on an ion current according to the current flowing through a motor and a motor control device of a hybrid vehicle. SOLUTION: An electric control unit(ECU) 40 reads a voltage value of an ignition plug 16 part generated by an ion current, and compares the read value with a designated value to conduct the required control operation when a misfire is determined. In the ion current detecting device of a hybrid vehicle, when a large current flows through a motor, noise is generated to have a bad influence to the ion current to cause wrong determination of a misfire. When a misfire determination limiting routine is executed, the noise present is determined when the detection values Im of currents of motors MG1, MG2 are larger than a designated amount, when the change rate (dIm/dt) of the detected current value is larger than a designated value, or when a regenerative control current Irm flows. Thus, it is possibe to prevent wrong determination of the engine combustion state according to the detection of an ion current influenced by noise.

    Abstract: PROBLEM TO BE SOLVED: To enable accurate learning of atmospheric pressure without using an atmospheric pressure sensor, in regard to an atmospheric pressure learning device mounted on an automobile having an evaporation fuel treatment system for combustion treatment in an internal combustion engine and an abnormality diagnostic device. SOLUTION: A selector valve 152 for making a canister 46 communicated/shielded with/from the atmosphere is provided on an atmospheric pressure side passage 144c connected to the canister 146. A pressure sensor 154 is mounted inside the passage in the canister 146 side from the selector valve 152, and a pump 156 is arranged so as to introduce negative pressure into inside of the passage. Abnormalities such as fuel leakage are detected, based on a pressure value from the pressure sensor 154 when the pump 156 is driven by closing a solenoid valve 142 for sealing and a solenoid valve 148 for purging and by switching the selector valve 152 to a state where the passage in the canister 146 side is shielded from the atmosphere. When the selector valve 152 is switched to a state where the passage in the canister 146 side communicates with the atmosphere, learning of the atmospheric pressure is performed by using the pressure value from the pressure sensor 154. Accordingly, the learning of the atmospheric pressure can be performed accurately without using an atmospheric pressure sensor. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To increase/decrease the power outputted from an engine more quickly when a sports drive mode is set by a driver. SOLUTION: When a sports drive mode is set, a lower limit engine rotational speed Nemin which is the lower limit of rotational speed of an engine is acquired according to a vehicle speed using a lower limit engine rotational speed map (step S160), and an engine rotational speed command Ne* is set so that the rotational speed of the engine is higher than the lower limit engine rotational speed Nemin (steps S170, S180). Thus, the engine is operated at the lower limit engine rotational speed Nemin or higher, to widen the torque width which an engine can decrease or increase, for quick increase/decrease of a torque. As a result, the power outputted from the engine is quickly increased or decreased. COPYRIGHT: (C)2005,JPO&NCIPI
