About the PhD thesis project :
In recent years, EMBs have drawn significant attention from both research communities and automotive brake suppliers alike, as they are deemed to be a promising replacement for hydraulic brakes in the automotive industry. However, the different nature of the actuator dynamics renders traditional ABS regulation logics unsuitable for future braking systems. The main goal of this thesis is to address the adaptation of ABS algorithms to EMB actuators, considering both disc and drum brakes. The approach proposed in this thesis is based on the regulation of the angular acceleration of the wheels. It also aims at considering the specificities of certain sensors and actuators, which induce additional constraints in the design of the braking system.
Key responsibilities and activities :
Over a 36-month period you will conduct the following research activities:
•Review the state of the art on ABS control algorithms for electromechanical brakes
•Study the stability of drum brakes from a perspective of control theory
•Study the braking distribution and its link with the lateral stability of a vehicle
•Development of simulation models of electromechanical braking systems
•Optimization of control algorithms for the regulation of wheel angular acceleration
•Design of ABS control algorithms adapted to electromechanical brake actuators
•Design of observers (Kalman filter) based on incremental encoder timestamping
•Coordination of testing activities (validation of the algorithms designed during the thesis on a test bench and a prototype vehicle)
•Synthesis and publication of the research results in various forms, including peer-reviewed journals and conferences and patent applications
•Writing of a PhD dissertation and oral defense of the thesis (Université Paris-Saclay)
•Compliance with the graduate school requirements for the obtention of the doctoral degree (ED STIC)
Key Professional Competencies :
•Solid background in automatic control
•Basic understanding of physics, electronics and mechatronics
•High proficiency in Matlab/Simulink or similar programming software
•Advanced English level (C1 or higher)
•Intermediate French level (B1 or higher)
Key Personal Competencies :
