Title: Innovations by Lothar Witte in Vehicle Performance Simulation
Introduction
Lothar Witte, a prominent inventor based in Vaihingen, Germany, has made significant strides in the field of vehicle performance simulation. With three patents to his name, he has focused on methods that enhance the understanding and testing of vehicle dynamics.
Latest Patents
Lothar Witte’s latest patents reflect his expertise in automotive technology. One notable patent is a method for simulating the performance of a vehicle on a road surface. This innovative method involves using torque-controlled electric load machines mounted on the powertrain's shafts and a computer that incorporates both a vehicle model and a tire model to simulate slip-dependent friction. This technique measures the angular wheel speed on at least one shaft and determines the tire's force transmitted to the roadway based on vehicle velocity and tire normal force.
Another significant patent developed by Witte is an arrangement for controlling the power transmission to both axles of a vehicle. This arrangement utilizes a friction element to limit rotational speed compensation based on the longitudinal speed difference between the vehicle's axles. It employs driving-speed-dependent tolerance bands to adjust the limiting process to optimize vehicle handling, potentially incorporating devices for tread radius adaptation and cornering correction.
