Latest Patents.

Jung’s listed patents focus on measuring a rail vehicle’s journey-related parameters and determining energy consumption during a test drive.

“Method and Device for Measuring a Parameter Relevant to the Journey of a Rail Vehicle” describes a control-loop method for determining a measurement value. The method ascertains torque acting on a vehicle-side rotational component and uses that value, together with the frictional engagement torque between the component and the rail, to calculate rotational acceleration and an expected rotational speed. A control device compares the estimated speed with the actual speed and produces an output used to recalculate the frictional engagement torque. The controller output, the recalculated torque value, or both can serve as the measurement value for storage or output.

“Method and System for Determining the Energy Consumption of a Rail Vehicle” sets out a method for measuring energy use during a test drive. It uses a locomotive system with a test locomotive component and a brake locomotive component, along with a test route and basic information about the train composition, load, route profile, and timetable. Driving and braking data are derived from the basic information and sent to the control system. During the test drive, the test locomotive component follows the driving data while the brake locomotive component applies braking according to the braking data, allowing the test component’s energy consumption to be measured. The patent also describes a system for carrying out the method.
