  • Patent number: 6928361
    Abstract: A control apparatus for a motor vehicle is provided in which each of a plurality of output values of the vehicle varies depending upon a plurality of input control parameters for controlling the vehicle. The control apparatus changes the input control parameter or parameters so that each of the output values becomes substantially equal to a corresponding target output value. The control apparatus then determines adapted values of the input control parameters, based on values of the input control parameters obtained when each of the output values becomes substantially equal to the corresponding target output value or falls within a permissible adaptation range of the target output value.

  • Patent number: 6349540
    Abstract: A three-way catalyst device having an oxygen absorbing/releasing capability is provided in an exhaust passage of an internal combustion engine. An upstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage upstream of the three-way catalyst device. A downstream-side air-fuel ratio sensor that outputs an output value in accordance with the air-fuel ratio of exhaust gas is provided in the exhaust passage downstream of the three-way catalyst device. A comparison value is calculated by comparing the length of an output locus formed by output values of the upstream-side air-fuel ratio sensor and the length of an output locus formed by output values of the downstream-side air-fuel ratio sensor. By comparing the comparison value with a predetermined criterion, it is determined whether the three-way catalyst device has deteriorated.
