Prof. Dr.-Ing. Carsten Markgraf, Parameter Optimization by doing Automated Tests with Formula Student Electric (FSE) Racing Cars , 27th August 2015.

 

Abstract:

For FSE events students build an electric, single seat formula race car with which they can compete against teams from all over the world. The competition is not won solely by the team with the fastest car, but rather by the team with the best overall package of construction, performance, and financial and sales planning.

The team from the University of Applied Sciences Augsburg (Starkstrom e.V.) has recently built their fourth racing car. In order to optimize the high level functions (e.g. Torque Vectoring, Traction Control, Recuperation,…) and the suspension system parameters, one of their cars was equipped with an autonomous system to perform automated, reproducible vehicle tests on the test track independent of the driver.

The acquisition of the vehicle position is done by Kalman Filter based sensor fusion of measured DGPS- and inertial sensor data. A closed loop controller determines the reference steering angle dependant on the position- and orientation error of the vehicle. An electric power steering is finally used to control the steering angle and to keep the car on the desired track.

Autonomous tests have been performed up to lateral accelerations of more than 10m/s². At the dynamic limits of the vehicle a significant reduction of understeering behaviour was achieved using the torque vectoring function.

Biography:

Prof. Dr.-Ing. Carsten Markgraf he received his Electrical and Electronic Engineering Degree from the University of Hanover in 2002 on the research topic “Autonomous Driving with Magnetic Nails” which was done in co-operation with Volkswagen AG. Afterwards he worked at ThyssenKrupp Automotive in Munich (Germany) and Eschen (Liechtenstein) in the area of “Active Suspension Control” and “Electric Power Steering (EPS)” and was finally responsible for the development and industrialization of the Electric, Electronic and Software for the EPS in the BMW X3, 3-series and 1-series cars which went into mass production in 2010. Since then he is Professor at the University of Applied Sciences in Augsburg and working in the areas of “Automatic Control” and “Electromobility” while being faculty advisor of the local Formula Student Electric team.
