Accelerated Time-to-Market for Powertrain Development and Fast System Verification incl. OTA-Updates

A key role at AVL for development, integration, calibration/applications & verification of the whole vehicle respectively the main systems (powertrain & energy storage systems), plays the highly flexible powertrain and vehicle in the loop (PaViL) test system. Besides the strong trend to virtual testing, there are still lots of development & testing tasks which require the actual HW system. The parallel use of virtual methods on SiL & HiL in combination with PaViL can increase the total development efficiency significantly. The paper describes a specific example, how to use this kind of special powertrain test sys-tem by multidiscipline development teams (i.e. energy consumption, efficiency, emission, feature testing incl. functional safety, diagnoses), with the same ONE UUT (unit under test) to perform the different development steps in an optimized & efficient way. The joined planning of test sequences and a high degree of automatization of performing tests & data processing allows the usage of the UUT & of the test environment almost 24/7. This reduces the need for prototype vehicles and on top of it, the whole development time is minimized to support short “time to market”.
