The need for highly accurate real-time simulation models is increasing with the “road to rig” approach. The major challenge in today’s vehicle development is focused on rapidly shortening vehicle development cycles. Vehicle simulation which is more than just vehicle inertia simulation enables significant progress in vehicle optimization and calibration, e.g. driveability as well as real world emission and fuel consumption optimization. AVL introduced a virtual vehicle model for engine testbeds which enables the simulation of real-world shaft oscillation phenomena (e.g. jerk). The counterpart for powertrain testbeds is a patented solution for the vehicle dynamics with wheel slip simulation. These requirements led to the creation of a modular and scalable controller with integrated simulation platform that ideally covers all requirements from individual testbeds up to applications in large-scale test facilities. BENEFITS AT A GLANCE • Reproducible and accurate results due to approved and optimized control algorithms • High level of user-friendliness in the manual operation • Approved safety concept for unmanned operation, 24/7 • Central administration of the parameterization in test facilities • Fast road to rig due to highly accurate real-time simulation • Open simulation platform for the integration of customer models TASK Parameterizing engines and their variants for different vehicles and countries constitutes the highest expenditure of time in the development cycle today. In order to accomplish this on testbeds in an automated manner, it is essential to have precise control over test subjects and the load facility. In order to increase efficiency, it is necessary for control parameters to be managed centrally in the test facilities, and it must be possible to unambiguously associate these parameters with the test results. During the operation of the testbed control system, the operator requires only minimal expert knowledge. Uniform, graphically supported, online-compatible parameterization that is also continuous across different testbed types reduces the expenditures for training measures as well as sources of errors. The option of adding functionality when specifically required allows for targeted investments. Here, the modular structure of the control system offers ideal adaptability to the current requirements with regard to measurement value collection, control functions and real-time platform. / 204
