He has made significant contributions to the field of automotive technology, particularly in active steering systems and hitch articulation mechanisms. With a total of 2 patents, Hall's work reflects a commitment to enhancing vehicle performance and safety.
Latest Patents
Hall's latest patents include innovative technologies that address critical aspects of vehicle operation. One of his patents is for "Methods and apparatus for an active front steering actuator." This invention features a motor controller that computes a position error from a commanded position value and an actual position value. The system operates in two modes: a commutation enable mode and a commutation freeze mode, depending on the position error. The commutation freeze mode ensures a constant motor hold torque when the position error is minimal, while the commutation enable mode corresponds to normal operation when the error exceeds a predetermined threshold.
Another significant patent is the "Sensing mechanism for hitch articulation angle." This invention provides a sensor mechanism for accurately measuring the hitch articulation angle. The design minimizes the impact of unwanted trailer motions, such as roll and pitch, while effectively registering trailer yaw motion. The use of a freely rotating ball and shaft allows for precise angle measurement through various sensors, including optical encoders and potentiometers.
