Latest Patents

One of his latest patents is a control apparatus for automatic transmission. This invention involves a control apparatus for an automatic transmission with multiple speeds, utilizing four sets and speed selecting mechanisms. The design assumes seven speeds among eight, labeled A to H, based on gear ratios. The first set includes A, which has the largest gear ratio, and C, which is the next but one. The second set includes at least H, which has the smallest gear ratio. The third set consists of B and D, while the fourth set includes two of E, F, and G. The system employs pressure regulators to selectively supply hydraulic pressure to the mechanisms corresponding to these sets.

Another significant patent is a control system for automatic vehicle transmissions. This system is designed to control an automatic transmission by determining the initial value of the desired pressure for a hydraulic clutch. This is particularly useful during power-on downshifting, as it effectively reduces shift shock experienced by the vehicle occupant, regardless of changes in throttle opening. The system also aims to minimize the volume of mapped data.
