Latest Patents
Tatumi's latest patents include innovative designs for a constant speed holding apparatus. The first patent describes a system that maintains a vehicle's cruise at a constant speed through both variable speed control and throttle control. This apparatus detects the difference between the set speed and actual speed during vehicle cruise. If the difference is smaller than a predetermined value, the system maintains the variable speed ratio to prevent speed vibrations caused by interference between the two control methods.
The second patent also pertains to a constant speed holding apparatus. It aims to maintain a constant vehicle speed by utilizing both variable speed control and throttle control. Upon detecting a specific point in time when the set vehicle speed is stored, the system makes corrections to ensure that the variable speed ratio prior to detection is used as the target. This innovation effectively prevents overshoot and undershoot issues, allowing for stable vehicle cruising at a constant speed.
