Electric Motor HIL-Simulation for automotive application: solutions, limitations, requirements

Contributor

Salah AKSAS

 

Objective

This lecture presents the differents kinds of real-time simulation technologies and example for automotive applications.

 

Outline

An increasing number of electric motors is used for automotive applications for energy saving due to power on demand, improved packaging of components (e. g. electric power steering), better availability (e. g. in HEV), Easier and less maintenance.
Why E-Drive HIL (Hardware-in-the-Loop) simulation? Because:
- Function tests in early development stages
- Tests under any desired conditions are possible
- Tests in the laboratory reduce time and cost
- Tests in failure and other dangerous situations are no-risk
- Reproducible and automated tests also reduce time and costs
Three kinds of HIL simulation can be defined: signal level, power level and mechanical level. Interest of each HIL simulation will be presented.
A short overview of the simulation hardware will also be given.
