Real-time control of a test bench simulation reproducing powertrain loads

In the testing of powertrain components during transient processes, a test bench capable of generating time-varying motion resistance for the powertrain can be utilized. With appropriate control and characteristics of the resistance generation system, it is possible to reproduce on the test bench the dynamic processes recorded during road tests of a vehicle equipped with a powertrain identical to the one being tested on the bench. In the article, the authors discuss the general concept of test bench control for the purpose of implementing a reproduction simulation and present the results of such a simulation using the presented concept implemented in a controller prototype programmed in the Matlab/Simulink system and deployed on a dSpace hardware platform.
CONTROL OF A REAL TIME TEST BED SIMULATION REPRODUCING LOADS FOR DRIVETRIAN WITH AUTOMATIC TRANSMISION
For testing drive train systems in transient processes test bed allowing to produce time varying motion resistance for drive train system can be used. Proper control and characteristics of resistance load generation system components gives the possibility to reproduce dynamic processes recorded during road test of car equipped with identical drive train system. In the paper authors describe overall concept of test bed control for the requirements of simulation reproducing dynamic processes of drive train and presents results of such a simulation performed with use of presented control concept. This concept was implemented using Matlab/Simulink software in controller prototype on dSpace platform. (…)
