Title: Innovations of Chao Sen Hsu in Electronic Throttle Control
Introduction
Chao Sen Hsu is a notable inventor based in Pittsburgh, PA (US). He has made significant contributions to the field of electronic throttle control, holding 2 patents that showcase his innovative approach to improving vehicle performance and safety.
Latest Patents
Hsu's latest patents include an "Input smoothing method and apparatus for an electronic throttle control." This invention provides a method and apparatus for smoothing a throttle plate position command before it is utilized by a closed-loop throttle control unit. The method involves sequentially indexing through a lookup table that stores a series of values of a smoothing function at routine time intervals. The difference between the current throttle plate command and the received throttle plate command is multiplied by the value of the smoothing function indexed from the lookup table. The product is then added to a reference throttle plate position command, generating a series of smoothed throttle plate position commands that enhance the operation of the throttle control unit.
Another significant patent is the "Method and system for absolute zero throttle plate position error." This invention addresses the initial and ongoing calibration of the absolute zero throttle plate reference position used in electronic throttle control systems. The method compensates for shifts in the absolute zero throttle plate reference position due to aging, wear, and thermal expansion or contraction. It monitors the torque output from a position controller when the throttle is commanded to be at the zero position, correcting the absolute zero position information until the torque required to maintain this position is within a specified window.
