How to simultaneously achieve low emissions and high efficiency in a hybrid powertrain
conference paper
In order to investigate the possibilities of hybrid driveline architecture and to provide a platform for further technical developments, TNO has designed and prototyped a test platform for a series hybrid powertrain, including a compact, highly advanced generator set. This powertrain is subjected to extensive hardware-in-the-loop testing. Beginning with an ambituous program of demands for a complete powertrain (fuel consumption, emissions and packaging) and using a sophisticated in-house developed simulation tool, a system was developed. System control is performed via a modular achitecture based on TNO's Modular Automotive Control System (MACS) with PPC555 CPU as central controller of the hierachial control network based on CAN with hybrid, generator set and BMS interfacing branch controllers. Internally developed control logarithms for these controllers were designed and optimised via simulation and rapid prototyped directly into the MACS via Matlab. During various phases of the project, the system is assembled, extensively tested and further developed as part of a simulated complete driveline using hardware-in-the-loop techniques with virtual electric drive and road load.
