Title: Innovations by Lars Bråthe in Torque Measurement Technology

Introduction

Lars Bråthe is a notable inventor based in Gothenburg, Sweden. He has made significant contributions to the field of torque measurement technology, holding a total of 4 patents. His work primarily focuses on enhancing vehicle transmission systems, particularly in relation to clutch assemblies.

Latest Patents

One of Lars Bråthe's latest patents is a torque measuring system and a method thereof. This innovative system is designed for vehicle transmissions and includes a clutch assembly with a two-part, rotatable torque transmitting member. The two parts of the member can move angularly relative to one another against the compression of at least one damper spring pack. An actuator with a non-rotatable cylinder controls the clutch, while a device for radiating and receiving wave energy is arranged to irradiate the damper spring pack. This setup allows for the reception of a reflected modulation signal that is proportional to the current resonance frequency of the damper spring pack. The modulation signal is then converted to a torque value by a signal processing device, which corresponds to the actual torque over the clutch.

Another significant patent by Bråthe is a torque calibration method. This method verifies engine torque estimation by estimating the engine torque based on the amount of fuel injected into the engine. It involves estimating a first vehicle weight value based on the vehicle's acceleration and the estimated engine torque. Additionally, it estimates an auxiliary brake torque using an auxiliary brake table and compares two vehicle weight values to detect any deviations in the actual engine torque value from the original.
