Currently working as a Controls Engineer at Hyundai Mobis for the development of indirect Tire Pressure Monitoring System (iTPMS) and anti-lock braking system (ABS). Tasks are ranging from development of the control logic to vehicle debugging and testing.
indirect Tire Pressure Monitoring System (iTPMS): - development and debugging of the TPMS logic (circumferential and frequency detection logics, vehicle mass estimation,...) - tuning of the TPMS parameters (development of a measurements evaluation tool in MATLAB to extract the tuning parameters) - vehicle debugging and vehicle tests (high and low mu) to ensure the robustness and performance of the TPMS logic/parameters - analysis and resolution of TPMS-related issues in customer projects - project management (contracting and coordination of the outsourcing companies, project costs evaluation, coordination with the clients...) Anti-Blocking System (ABS): - development and debugging of the ABS logic - analysis and resolution of ABS-related issues in customer projects
Entwicklung Fahrwerk/Fahrdynamik/Reifen Thema: Untersuchung des Einflusses der Reifeneigenschaften auf das ABS-Regelverhalten: - Bestimmung von mu-Schlupfkurven mit dem Pacejka-Modell und seinen Koeffizienten für ABS-Bremsmessungen, die mit Testfahrzeugen durchgeführt wurden. - Untersuchung des Einflusses der Pacejka-Koeffizienten auf den Bremsweg mithilfe eines statistischen Versuchsplans. Erstellung eines Vorhersagemodells für den Bremsweg in Abhängigkeit von den Pacejka-Koeffizienten (und damit der mu-Schlupfkurve). - Validierung des Modells anhand von ABS-Bremssimulationen. - Untersuchung des Einflusses von Reifengrip-Variationen auf den Bremsweg bei simulierten ABS-Bremsungen. Chassis development/Vehicle dynamics/Tires: Investigation of the influence of tire properties on ABS control behaviour: - Determination of mu-Slip curves with the Pacejka model and its coefficients for ABS braking measurements carried out with test vehicles. - Study of the influence of Pacejka's coefficients on braking distance using a Design of Experiment (DoE) model. Establishment of a predictive model of braking distance as a function of Pacejka coefficients (and therefore of the mu-Slip curves). - Validation of the model using ABS braking simulations. - Study of the influence of variations in tire grip on braking distance during simulated ABS braking.
Entwicklung Fahrwerk/Fahrdynamik/Reifen: - (Mit)entwicklung einer Datenbank für das logistische Management von Reifen. - Entwicklung von MATLAB-Skripten zur Erleichterung der Analyse von objektiven Reifenmessungen, die mit Fahrzeugen durchgeführt sind. Chassis development/Vehicle dynamics/Tires: - (Co-)development of a database for the logistical management of tires. - Development of MATLAB scripts to facilitate the analysis of objective tire measurements performed on vehicles.
