To accomplish this on testbeds in an automated manner, it is essential to have precise control over test subjects and the load facility. Increased efficiency 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. Operational simplicity 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 training costs as well as errors. Consistent usability 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. APPROACH Decades of experience in the field of testbed control as well as detailed knowledge of the development processes of our customers have significantly influenced the development of AVL testbed controllers. The need for precise real-time simulation models is increasing with the “road to rig” approach. The major challenge in today’s vehicle development is to rapidly shorten vehicle development / 224 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 provides a stable and robust 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 environment which ideally covers all requirements from individual testbeds up to applications in large-scale test facilities. BENEFITS AT A GLANCE • Approved safety concept for unmanned operation, 24/7 • Central administration of parameterization in test facilities • Fast road to rig due to highly accurate real-time simulation • Open simulation environment for the modular integration of customer real-time models • Central administration and distribution of real-time applications in a test field
