Title: Innovations by Daniel N Wehrwein
Introduction
Daniel N Wehrwein is an accomplished inventor based in Holly, MI (US). He has made significant contributions to the field of powertrain technology, holding 2 patents that showcase his innovative approach to vehicle systems.
Latest Patents
One of Wehrwein's latest patents is titled "Transmission clutch control using lumped inertia modeling." This invention involves a vehicle powertrain that includes an engine, transmission, torque converter assembly, and a controller. The controller utilizes recorded lumped inertia models of the powertrain to execute a clutch-to-clutch shift, effectively reducing powertrain dynamics to two or three degrees of freedom. The method estimates clutch torques using these models, which include primary inertia blocks that describe engine inertia and the inertia of a torque converter pump. The controller derives a required output torque value as a closed-loop target value, ensuring efficient powertrain operation.
Another notable patent is "System and method for reducing powertrain disturbances based on system energy." This control system features an energy determination module and a speed control module. The energy determination module assesses the rotational energy input to the powertrain during a negative lash event. The speed control module selectively limits the increase in the engine's rotational speed based on the determined rotational energy, enhancing the overall stability and performance of the powertrain.
