    摘要： A controller controls a purge amount adjusting valve provided in a purge passage, thereby purging an amount of vapor in accordance with an operating state from a canister into an intake passage. The controller detects an internal pressure of a fuel tank with a pressure sensor provided therein, and determines the fact that a tank internal pressure control valve provided in a vapor passage is open based on the detection result. When the controller determines that the tank internal pressure control valve is open, the controller can, e.g., fully close the purge amount adjusting valve and then gradually open the opening amount of the purge amount adjusting valve such that an amount of vapor in accordance with the operating state is purged.

    摘要： The device according to the present invention controls air-fuel ratio of the exhaust gas flowing into the catalytic converter in such a manner that the exhaust gas flowing into the catalytic converter fluctuates around a center value on the lean air-fuel ratio side compared to the stoichiometric air-fuel ratio when it performs the determination of deterioration of the catalytic converter. In this condition, the device calculates the rich gas inflow amount which is the amount of HC and CO in the exhaust gas flowing into the catalytic converter and the rich gas outflow amount which is the amount of HC and CO in the exhaust gas flowing out from the catalytic converter. The device, then, determines the degree of deterioration of the catalytic converter based on the calculated values of the rich gas inflow amount and the rich gas outflow amount. Since the difference between the rich gas inflow amount and the rich gas outflow amount represents the amount of HC and CO oxidized by the catalytic converter, the deterioration of the catalytic converter can be determined accurately by comparing the rich gas inflow amount and the rich gas outflow amount.

    摘要： A catalyst deterioration detection device for an internal combustion engine, according to the present invention, includes a three-way catalyst mounted in an exhaust passage of the internal combustion engine and having an O.sub.2 storage capability and an air-fuel ratio sensor, mounted upstream of the three-way catalyst, for linearly detecting an air-fuel ratio. An air-fuel ratio feedback control unit, based on the output of the air-fuel ratio sensor, calculates a feedback correction amount consisting of a proportional term for bringing the air-fuel ratio to stoichiometry and an integral term for bringing an integrated value of an error between the air-fuel ratio and stoichiometry to zero. An O.sub.2 sensor, mounted downstream of the three-way catalyst, detects whether the air-fuel ratio is rich or lean. A catalyst deterioration determining unit determines deterioration of the three-way catalyst on the basis of the length of a response curve that the output of the O.sub.2 sensor describes during the time that air-fuel ratio feedback control is being performed by the air-fuel ratio feedback control unit. A response curve length calculation interrupting unit interrupts the calculation of the response curve length being performed by the catalyst deterioration determining unit for a predetermined length of time when the output of the air-fuel ratio sensor or the amount of change of the output has exceeded a preset value.

    摘要： The device according to the present invention controls air-fuel ratio of the exhaust gas flowing into the catalytic converter when performing the determination of deterioration of the catalytic converter in such a manner that the amount of oxygen released from a three-way catalytic converter is maintained at a suitable value for determining the deterioration of the converter. When the air-fuel ratio of the exhaust gas flowing into the catalytic converter fluctuates between a rich air-fuel ratio and a lean air-fuel ratio, the catalytic converter absorbs oxygen from the exhaust gas when the air-fuel ratio of the exhaust gas is rich, and releases the absorbed oxygen when the air-fuel ratio of the exhaust gas is lean. According to the present invention, the amount of oxygen released from the catalytic converter during the rich air-fuel ratio period of exhaust gas is controlled to a predetermined amount. This amount is set at the value larger than the maximum oxygen absorbing capacity of a deteriorated catalytic converter, and smaller than the maximum oxygen absorbing capacity of a normal catalyst. Therefore, the air-fuel ratio of the exhaust gas flowing out from a deteriorated catalytic converter fluctuates largely, while the air-fuel ratio of the exhaust gas flowing out from a normal catalytic converter does not fluctuate. Thus, deterioration of the catalytic converter can be determined accurately.

    摘要： A hybrid vehicle according to one of embodiments of the present invention generates a driving torque using an internal combustion engine, an motor generator, and the like when a shift position is a driving position, the driving torque being determined based on a selected driving mode (e.g., a power mode to give priority to the power, and a normal mode to give priority to fuel consumption) and an accelerator operation amount. On the other hand, when the shift position is a neutral position, the vehicle maintains a rotational speed of the engine at a constant speed (including zero when the engine is stopped) regardless of the accelerator operation amount. When the accelerator operation amount becomes equal to or larger than an accelerator operation amount threshold while the neutral position is selected, the vehicle supplies information indicating that the neutral position is selected to a driver. The accelerator operation amount threshold is determined based on the driving mode.

    摘要： An electrically-driven vehicle 10 comprises a chargeable and dischargeable battery 20, a charger 16 that charges the battery 20 using a supply of electric power from an external power supply 100, an accessory unit 19 that is driven by a supply of electric power from at least one of the battery 20 and the charger 16; and a PM-ECU 18 that controls drive of the charger 16 so that the charged amount of the battery does not exceed a predetermined charging upper limit. The PM-ECU 18 sets the charging upper limit used when the accessory unit 19 is being driven, lower than the charging upper limit used when the accessory unit 19 is not being driven in order to avoid overcharging when excessive electric power is supplied from the accessory unit 19 to the battery 20.
