The Clemson Vehicular Electronics Laboratory (CVEL) conducts targeted research related to automotive and aerospace vehicle electronics including electronic components, circuits, sensors, communications, power distribution and mechatronics with an emphasis on systems integration, electromagnetic compatibility and modeling. The lab is located in the Carroll A. Campbell Jr. Graduate Engineering Center on the campus of the Clemson University International Center for Automotive Research (CU-ICAR). It is equipped to make a wide range of electromagnetic emission and susceptibility measurements. It is also equipped to do real-time RF data collection and processing, as well as diagnostic testing and analysis. CVEL researchers specialize in the electromagnetic modeling and measurement of highly complex electronic components and systems.
This site has four main sections. The automotive electronics section includes tutorials and information relevant to electronic systems in cars, trucks, tanks, submarines, ships and various other land and water vehicles powered by gasoline, fuel cells, batteries or hybrid systems. The aerospace electronics section is devoted to electronics in air and space vehicles. Electromagnetic compatibility (EMC) plays an extremely important role is the development and maintenance of the electronic systems in all vehicular designs and therefore an entire section of the web site is devoted to EMC and the control of conducted and radiated electromagnetic interference (EMI), including intentional electromagnetic interference (IEMI). This section includes several tutorials and a collection of "EMC Design Guidelines". Finally there is a section devoted to electromagnetic modeling. Computational electromagnetic modeling tools are becoming an increasingly important part of the automotive and aerospace electronics design process. This section describes the tools that are available and provides tutorial information for people who are just getting started in EM modeling.
Information on our laboratory can be accessed using the links in the sidebar on the left. These links include descriptions of some of our current projects as well as an overview of our staff, facilities and services.

What's New at CVEL
The Automotive Electronic Systems pages have been significantly updated for 2013.
A new calculator for plotting the step response of an RLC circuit has been added to the EMC page.
EMC Tutorials that were formerly found on the main EMC page have been updated and are now maintained on the LearnEMC website.
Prof. Hubing authored a chapter in the book, Automotive Informatics and Communicative Systems. The book can be found on Amazon.com or individual chapters can be obtained from IGI Global.
