Latest Patents

Ogiso's latest patents focus on the development of an abnormality detection apparatus and method for air/fuel ratio sensors. The first patent describes an apparatus that includes an air/fuel ratio control portion, which fluctuates the air/fuel ratio between rich and lean states. It features a data acquisition portion that collects data to detect abnormalities by measuring responsiveness during changes in the output of the A/F sensor. Additionally, it includes a straight line setting portion that establishes a trend line based on the acquired data, and an abnormality determination portion that assesses the presence of abnormalities by comparing the gradient of the trend line with a predefined criterion value.

The second patent also addresses abnormality detection in air/fuel ratio sensors. This apparatus includes a data acquisition portion that captures responsiveness parameters while the sensor output changes between rich and lean peaks. It features an abnormality determination portion that evaluates the sensor's condition based on the collected data, along with a distribution width determination portion that calculates the distribution width of the data. The determination of abnormality is made by comparing this width with an established criterion value.
