Experimental Testing of Vehicles

 Average 0 out of 5

A course for community college students and automotive test technicians in the area of vehicle experimental testing. It can be included in an automotive engineering curriculum.

Description:
Students will do practical laboratory-based studies on various sensors and data acquisition systems (DAQ), setting up test procedures, wiring up sensors for measurements, conducting experiments, recording experimental data, and analyzing test results. Gaining experience on estimating experimental vehicle characteristics and writing a test report is an important part of the course.

An experimental project based on the testing of a virtual hybrid-electric vehicle with the use of an actual DAQ is included in the course. The lab work and the course project are supplemented by lectures. National Instruments LabVIEW and myRIO, MATLAB/Simulink are in use for laboratory work and course project. The course is designed to meet over a period of 15 weeks, 2 meetings per week, and 1h 30min per meeting.
