    摘要： The device for determining deterioration of a catalytic converter includes a catalytic converter disposed in the exhaust gas passage of the engine and an air-fuel ratio sensor disposed on the exhaust gas passage downstream of the catalytic converter. The device performs two types of determining operations based on the length of the output response curve of the downstream air-fuel ratio sensor, one is a deterioration determining operation which determines whether the catalytic converter has deteriorated and the other is a normal determining operation which determines whether the catalytic converter is normal. The device also estimates the temperature of the catalytic converter based on the operating condition of the engine, and sets a deterioration diagnosis intake air flow range and a normal diagnosis intake air flow range in accordance with the estimated temperature of the catalytic converter. The device performs the deterioration determining operation or the normal determining operation in accordance with whether the intake air flow rate of the engine is within the deterioration diagnosis range or the normal diagnosis range.

    摘要： In an internal combustion engine in which air-fuel ratio feedback control is performed using an A/F sensor mounted upstream of an exhaust gas purifying catalyst, a deviation in the characteristic of the A/F sensor is estimated and the air-fuel ratio feedback control and catalyst deterioration judging processes are performed accounting for the estimated deviation. If the characteristic of the A/F sensor deviates in an output increasing direction, the amount of fuel correction will become excessively large, and the period from the time an output voltage VAF crosses a target voltage VAFT to the time it returns to the target voltage will become short compared with a normally functioning A/F sensor. On the other hand, if the characteristic of the A/F sensor deviates in an output decreasing direction, the amount of fuel correction will become excessively small, and that period will become long compared with a normally functioning A/F sensor. In the present invention, the output voltage VAF of the A/F sensor is monitored, and its amplitude VP and period CPER are calculated; then, based on the relationship between them, a correction factor K for correcting VAF based on the characteristic deviation is obtained. Instead of the amplitude VP and period CPER, a response curve length and an area enclosed by VAF and VAFT may be used.

    摘要： The device according to the present invention determines whether the catalytic converter has deteriorated based on the outputs of an upstream air-fuel ratio sensor and a downstream air-fuel ratio sensor only when the flow rate of the intake air is within an allowable flow range. Further, the allowable range is determined in accordance with operating conditions of the engine, for example, the temperature of the catalytic converter. Since the O.sub.2 storage capability of the catalytic converter changes in accordance with the temperature of the catalytic converter, different determination results may be obtained for the same catalytic converter if the determination is carried out at different temperature. In this invention, for example, the flow range is selected in accordance with the temperature of the catalytic converter in such a manner that a normal catalytic converter is always determined as being normal and a deteriorated catalytic converter is always determined as being deteriorated. Therefore, in the present invention, the deterioration of the catalytic converter is correctly determined regardless of a change in the operating conditions of the engine.

    摘要： A vehicle is configured to be able to charge an electrical storage device using an external power supply outside the vehicle. A charger receives electric power supplied from the external power supply to charge the electrical storage device. A current sensor detects a current input to or output from the electrical storage device. During external charging, when the charger and the auxiliary load are turned off and a determination condition for determining that the current (IB) is zero on the basis of the value detected by the current sensor is satisfied, the controller carries out offset learning of the current sensor.

    摘要： A vehicle is a vehicle in which a high-voltage power supply can be charged with electric power from an external power supply. In a travel mode, a main microcomputer (MMC) of a controller outputs a request signal requesting to forcibly turn a plug-in main relay (PIMR) on to a sub-microcomputer (SMC), in order to activate a charging system that is essentially not required to be activated. Upon receiving the request signal, the SMC outputs a signal for turning the PIMR on to the PIMR. If the MMC does not receive electric power from a low-voltage power supply via the PIMR after outputting the request signal, the MMC determines that there is an abnormality in an activation circuit for the charging system, and alerts a user.

    摘要： A charger is operable in a normal mode such that output power matches a provided electric power command value CHPW, and limits the output power to a limit value PS in a saving mode if the electric power command value CHPW exceeds the limit value PS. A charging ECU performs feedback-control for compensating for the electric power command value CHPW such that a charging power monitor value PM sensed by a charging power sensing unit matches a target value PR, and in addition, limits an increase in the electric power command value CHPW such that the electric power command value CHPW does not significantly deviate from the target value PR. As a result, in a vehicle charging system on which an add-on charger having a power saving function is mounted, stabilization of the behavior when the add-on charger returns from a saving operation to a normal operation is allowed.
