摘要： An electronic control device calculates the maximum actual oxygen storage capacity of a catalyst. The gradient of a linear expression formed between the catalyst temperature and the maximum oxygen storage capacity of the catalyst is stored for each degradation level of the catalyst. The gradient can be learned in accordance with the same temperature of the catalyst and the maximum actual oxygen storage capacity. When the maximum actual oxygen storage capacity is calculated, it is revised in accordance with the temperature of the catalyst, a reference temperature, the linear expression, and the learned gradient. The revised maximum oxygen storage capacity which is the maximum oxygen storage capacity when the temperature of the catalyst during the same calculation period is equal to the reference temperature is then calculated. If a response delay is detected in the output of an oxygen sensor, the gradient of the learned linear expression is discarded.

摘要： A determination oxygen storage amount used to determine whether a catalyst is degraded is a value obtained by applying a correction amount for removing error caused by response delay time of an output signal of an oxygen sensor to an oxygen storage amount calculated every short time. The correction amount is a value that is calculated using slopes stored in memory, i.e., the slopes for the number of storage cycles (>the short time) corresponding to the response delay time, or the like, and becomes more accurate as a value corresponding to the error as the storage cycle becomes relatively shorter with respect to the response delay time and the number of the slopes stored in the memory increases. The necessary storage capacity of the memory is inhibited from increasing excessively even if the number of the slopes stored in the memory is large.

摘要： An abnormality determination apparatus includes: a detecting unit repeatedly detecting a state quantity, which correlates with an operating state of an evaluation target device, at time intervals; and a determining unit determining whether there is an abnormality on the basis of multiple pieces of data about the state quantity, detected by the detecting unit and stored. The apparatus counts the number of the stored data as a total storage number after there occurs a situation that no data are stored, permits the determining unit to execute abnormality determination on the condition that the total storage number has reached a first threshold in a first trip after the situation occurs, and permits the determining unit to execute abnormality determination on the condition that the total storage number has reached a second threshold that is smaller than the first threshold in a second trip or later after the situation occurs.
