Introduction
Harald Stehle is a notable inventor based in Tettnang, Germany, who has contributed significantly to the field of gearbox technology. With a total of four patents to his name, Stehle is making waves in the automotive industry, particularly through his intricate designs for transmission control systems.
Latest Patents
Among his latest innovations is a patent for a Transmission Control System. This gearbox incorporates an input shaft alongside first and second proportionally controllable shift elements (A to F). The unique aspect of this design is its ability to control the engagement and disengagement of gear ratios within the gearbox through an open-loop system. The methodology involves determining a specified differential speed profile, which represents the difference between the rotational speed of the input shaft and the synchronous speed of the gear ratio to be engaged. Additionally, it evaluates the torque demand from a connected drive source or formulates a control profile for engaging one of the shift elements based on the speed profile.
Another significant patent relates to a method for the open-loop control of a gearbox featuring the same proportionally controllable shift elements. This procedure includes the disengagement of the first shift element according to a first control profile and the engagement of the second shift element according to a second control profile. Notably, the first control profile takes into account a variable portion influenced by the temperature within the gearbox.
