AEL2501 Modern Automotive Systems Common for: AEL, AE and APD courses Module Leader: Prof.Ashok Meti 1
Module Aims and Summary The aim of this module is to prepare the students to critically evaluate the challenges and identify the role of electronics and software systems in a modern automobile. Students are taught basic automotive systems, underlying principles of construction and working, limitations of the conventional systems, the needs for electronic controls to improve the performance, safety and meet regulatory requirements. Also, they are motivated tdt to explore potential til new functions and applications by studying the physical systems, interacting with experts and users. 2
Intended Module Learning Outcomes After undergoing this module students will be able to: Describe the features and functioning of electronic systems in a modern automobile Identify the case for use of modern electronics technology to improve the performance, safety, comfort and related issues Explore addition of new features in the existing electronic automotive subsystems for enhanced functionality 3
