Title: Innovations of David H Vu
Introduction
David H Vu is a notable inventor based in East Lansing, MI (US). He has made significant contributions to the field of automotive technology, holding a total of six patents. His work primarily focuses on improving vehicle transmission systems, which are crucial for enhancing performance and efficiency.
Latest Patents
Among his latest patents is a method and apparatus to control a continuously variable transmission (CVT). This innovation describes a powertrain system that includes an internal combustion engine rotatably coupled to a CVT. The method for controlling the CVT involves determining minimum and maximum input speeds based on accelerator pedal position, while also monitoring vehicle speed and CVT input speed. A target CVT input acceleration rate is established based on vehicle speed, leading to a desired speed ratio that is responsive to this acceleration rate. The CVT is then controlled according to the desired speed ratio.
Another significant patent is the transmission system with clutch bite point learning logic. This method involves learning the bite point of a position-controlled clutch in a vehicle. It includes commanding the engagement of a clutch fork via a controller when the transmission is in park and the engine is idling. The method also controls the apply position of the clutch, calculates its torque capacity, and measures the apply position through a position sensor. The recorded apply position becomes the clutch bite point when the calculated torque capacity matches a calibrated value, allowing for improved transmission control.
