How you'll learn
100 % online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetable: students progress at their own pace within the intake period, making it possible to combine with work.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is MATLAB/Simulink, CarSim, MSC Adams Car, MoTeC i2 Pro, Python (pandas), in free, academic or evaluation versions. Tests are studied using real procedures for acceleration and braking tests in sand, comparison of tyre pressures on dunes, and acquisition of wheelspin and speed data. Assessment is continuous per module plus the final integrating project.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
Explain the phenomena of sinkage, resistance and traction in loose sand.
Build a longitudinal vehicle model on deformable terrain.
Adjust tyre pressures to maximise flotation.
Select gear ratios and engine speed for dune driving.
Apply safe driving techniques on ascents, descents and crests.
