Latest Patents

One of Okumura's latest patents is an "Apparatus for controlling automatic transmission during downhill running." This innovative shift control apparatus regulates the speed ratio of an automatic transmission in a motor vehicle while it is running downhill. It does this by comparing the actual acceleration value of the vehicle with a reference acceleration value. The apparatus includes a device that determines the reduction of the actual output of the engine relative to the desired output, based on the accelerator pedal's operating amount. Additionally, it features a device that reduces the reference acceleration value by a compensating amount that decreases as the vehicle's running speed increases.

Another significant patent is the "Apparatus for diagnosing automatic transmission based on engine speed." This diagnosing apparatus is designed for vehicle automatic transmission systems, which include frictional coupling devices and solenoid-operated valves. It detects the engine speed and determines a reference range within which the engine speed is expected to fall when the transmission is in a selected position. The apparatus also assesses whether a predetermined running condition of the vehicle is met and identifies any defects in the automatic transmission system based on the detected engine speed.
