Low Cost, Educational Internal Combustion Engine Electronic Control Unit Hardware-in-the-Loop Test Systems
Different hardware platforms and their associated real time operating systems that can be used in an educational laboratory for illustrating engine electronic control unit hardware in the loop testing are presented and compared in this paper. A Matlab graphical user interface prepared for generating synthetic crank and camshaft angular position sensor signals to be fed to the engine electronic control unit during hardware-in-the-loop testing is introduced. This graphical user interface is used to generate faulty sensor signals to check the response of the engine electronic control unit during hardware-in-the-loop simulation. Examples of faulty signals that can be generated with the graphical user interface are illustrated.
