LABCAR HiL Systems − Proven in the Development of Hybrid Propulsion Systems
The LABCAR HiL system from ETAS is deployed worldwide for applications such as function, diagnostic, and acceptance testing. It is also proving its capabilities in nu­mer­ous development projects of hybrid and fuel-cell propulsion systems. In that con­text, LABCAR excels especially because of its modular hardware architecture and its ability to concurrently calculate model segments on different processor cores of the multi-core simulation computer. The result is a clear advantage in time savings when simulating many similar battery cells, or when testing the control functions of an inver­ter/electric motor. In the latter case, a clock cycle must be processed about 10 times faster than with an internal combustion engine.
As regards the generation of electrical power − up to 150 kW for the purpose of test­ing electrical machines and inverter hardware − ETAS cooperates with third-party sup­pliers, such as Scienlab or Silver Atena. This enables ETAS to offer a package solution for hybrid HiL systems. The Electric Vehicle and Hybrid Technology Business Unit at Robert Bosch GmbH has introduced LABCAR HiL testing systems that reliably meet all of the demands made on a hybrid testing system. The new HiL system at Robert Bosch GmbH provides an impressive demonstration of the versatility of LABCAR, and of the specific efficiency of the Scienlab emulators. As an added benefit, the system is easily and economically adaptable to future requirements.
With regard to models, too, LABCAR is open to being extended through the addition of third-party products. The PC-based architecture of the RTPC supports all major model­ing tools, such as TESIS DYNAware, GT-Power, or CarSim.
Thanks to its open system architecture and its ability to effect model partitioning and the subsequent, concurrent high-speed calculation of the resulting segments, LABCAR is ideally suited for use with new propulsion concepts. As a tangible benefit, ETAS supplies its comprehensive automotive expertise, which is also available for customer-specific solutions.
