Latest Patents

Hughes' latest patents include a "Torque managed traction control for the drive wheels of an automotive" and "Air fuel ratio control using time-averaged error signal." The first patent focuses on an electronic driveline controller and traction control method for engine-driven vehicles. This invention controls the tractive effort of the driving wheels to prevent excess slip relative to the road surface. It achieves traction control through total powertrain torque management, where the torque delivered to the driving wheels is adjusted based on sensed operating variables. The second patent addresses the control of the air-fuel ratio in internal combustion engines. It utilizes feedback from an exhaust gas oxygen sensor, sampling the sensor output periodically. The control method employs time-based averaging of the oxygen sensor signal to generate an error signal, which reflects the difference between the actual and desired air-fuel ratio.
