HIL can be described as hav ing the physical part of a system (for
8、in sta nee, part of a vehicle as a simulation while the electronic control unit (ECU is represented by either a product ion ECU or a prototype ECU. This will make it possible to test the ECU before putting it into a vehicle, this to eliminate bugs in the ECU in early stages of the developme nt.The A
9、MESim RT product makes the process of creat ing a real-time simulatio n model simpler and faster. It must be no ted that the AMESim model mea nt for real-time ofte n n eeds to be reduced. There are a nu mber of tools in AMESim for assisti ng in this task, the most importa nt ones are:? Eige n value

There is a strict relati on ship betwee n the eige n values in a model and the time step it can be simulated with. For details about eigen-value a

Since AMESim RT is an exte nsion of the AMESim/Simuli nk in terface it is useful if reader is familiar also with t

We recomme nd that the user at least goes through some of tutorial examples for the realtime en vir onment concern ed. Both AMESim and the real-time software are complex software that requires that a
