Project adtyre: towards dynamic tyre inflation control

Abstract

The paper presents the results of the research project ADTYRE that is concentrated on the development of dynamic tyre pressure control systems (TPCS) with the aim to reduce rolling resistance and to improve driving safety. The project is coordinated by the Ilmenau University of Technology (Germany) in cooperation with Gumpert Sportwagenmanufaktur GmbH (Germany), senTec Elektronik GmbH (Germany), Vilnius Gediminas Technical University (Lithuania), and Szent István University (Hungary). The paper covers the following content: (1) State-of-the-art of tyre pressure monitoring and control systems; (2) Simulation study to estimate the potential of high-dynamic tyre pressure adaptation to the actual driving situation and operational state of the tyres; (3) TPCS design procedure using complex simulation tool (AMESim, IPG CarMaker); (4) Design of a data acquisition system with high sampling rate to monitor the tyre pressure and temperature; (5) Functional validation of the TPCS approach with experiments on the test rig and real car. Results of the laboratory and vehicle testing point out that the developed dynamic tyre pressure control system has an evident potential in increasing the vehicle safety and performance.
