/ 111 Vehicle Testbeds 4x4 for Advanced Applications in R&D The development of new drive concepts and powertrain functionalities entails new requirements for test systems. For this, AVL offers high-end solutions fulfilling these challenges. CHARACTERISTICS All four highly dynamic load units of the vehicle testbed can be controlled separately or synchronously. This is possible for generic analyses and also forms the basis for real-life testing in connection with AVL InMotion™ powered by CarMaker. Previously recorded 3D road profiles including curves can be modeled. Along with the conventional method (by means of coast-down coefficients), the road simulation is implemented in an advanced way on the basis of a physical multi-body simulation model linked to an environment, real road and driver model. This allows for highly varied parameters like air resistance, vehicle weight, trailer and driving style. Additionally, a comprehensive residual bus simulation can be implemented on the basis of the simulation model (e.g. simulation of acceleration or traffic for ACC systems). APPLICATION The range of applications for 4x4 vehicle testbeds for advanced applications is broad: • Real consumption and emission analyses based on customer-specific roads (e.g. Auto Motor and Sport track) • Development of advanced driver assistance systems using free maneuver, road, and traffic definitions • Analysis of different (virtual and reproducible) driver types linked to vehicle operating strategies BENEFITS AT A GLANCE • Highly dynamic four-motor vehicle testbed for modeling different pulling forces and speeds on all four wheels • Future-proof development platform for intelligent drive concepts such as electric drives as well as complex powertrain functionalities (e.g. torque vectoring) • Maneuver-based real-life testing on the vehicle testbed • Parameterizable simulation models for driver, road and topology, environment and residual vehicle Real-life testing on the vehicle testbed
