<p>Master Thesis Project at </p><p>ÅF, Automotive Project Center Title: Advanced control of future electric propulsion systems that meet the dynamic requirements of small passenger vehicles</p><p>Background Electric propulsion systems have advantages over conventional ones regarding high power density, short response time and better controllability. However, for future vehicles, equipped with more sophisticated safety functions, the requirements for controllability will be even higher. Also new driving cycles used for energy consumption, correlating better with normal driving, will put higher demands on drivetrain control.</p><p>Objective The task is to study potential measures to improve controllability of electric drivetrains, in the view of ongoing development trends. </p><p>Methods Through literature studies and interviews with subject matter experts, determine status and trends in e-motor technology, transmissions and power electronics. Analyse strengths and weaknesses regarding controllability of current and future systems. Develop principles, methods and solutions to improve the control accuracy, response time, predictability and reliability. Identify electrical as well as mechanical measures. Finally, demonstrate the findings theoretically with vehicles performing active safety manoeuvres. Driving scenarios of interest are quick acceleration (to prevent rear end collision), braking on low/split- and crash avoidance manoeuvres using lateral displacement.</p><p>Deliverables A report including: a) technical trends in electric propulsion technology b) principles for improving controllability, i.e. response time, precision and predictability c) demonstration of a typical drivetrain with/without improvements</p><p>Contact Gunnar Olsson, [email protected], +46 705 185 794 Stefan Karlström, [email protected], +46 723 767 523</p><p>Please submit your application at: www.afconsult.com/jobb</p><p>Master Programs: Automotive Engineering, Applied Mechanics, Electric Engineering Product Development, Production Engineering</p><p>ÅF is an engineering and consulting company creating progress for our clients since 1895.
