Latest Patents

Among his latest inventions is the "Exhaust purification apparatus for an engine," which incorporates a catalytic converter within the engine's exhaust system. This apparatus uses first and second exhaust sensors placed on the upstream and downstream sides of the catalytic converter. The detected values from these sensors are utilized for feedback control of the air-fuel ratio and for assessing the deterioration of the catalyst. By adjusting the control constant of the air-fuel ratio, the apparatus ensures that the second exhaust sensor operates according to the catalyst's condition.

Another noteworthy invention is the "Method of suppressing gear-shifting shock in an automatic transmission." This method aims to minimize gear-shifting shock in vehicles equipped with automatic transmissions by adjusting engine output power during gear-shifting. The adjustment of engine power is strategically timed to coincide with the completion of the gear shift, based on the relationship between engine speed and a defined characteristic curve. The method employs learning algorithms to set the completion decision rotational speed for each gear-shifting instance by monitoring the preceding engine speed.
