Latest Patents

Katou's latest patents focus on methods and apparatuses for automatic transmission cruise control. The first patent addresses the prevention of hunting between a selected gear ratio, such as overdrive, and the next lower one when a vehicle ascends a slope under cruise control. This innovation involves an automatic speed control device (ASCD) that issues control signals to the transmission control circuit, allowing for an upshift to the predetermined gear ratio while inhibiting downshifting during operation. When the vehicle speed falls below a predetermined target value, the ASCD signals the transmission to downshift, ensuring optimal performance. The second patent similarly limits the throttle valve opening to prevent unnecessary downshifting, thereby enhancing the vehicle's ability to maintain speed on inclines.
