This family of products can also be used in the field of: • Exhaust gas emission and endurance tests • SHEDs for the testing of vehicles fuel perspirations • Climatic and altitude chambers BENEFITS AT A GLANCE • Robust design combined with reproducible and absolute measuring and control accuracy for the use in laboratories and in most different climate zones • Highly precise control around zero km/h for realistic and dynamic vehicle designs • Comprehensive vehicle testbeds meet all customer requirements for axle load, performance, mass simulation quality, ease of use and extendability • High levels of torsional rigidity in combination with the AVL controller VECON allow for torque vectoring tests of state-of-the-art powertrain systems The increasing complexity of the powertrain management systems and the close interaction of engine and transmission control unit, in combination with emission regulations often require a common R&D test. CHARACTERISTICS AVL ROADSIM 25“INLINE, used for testing light vehicles from mopeds up to light, four-wheeled vehicles, is based on an inline solution. There are three different product configurations: from a 400mm wide roller via a connectible roller up to a 1,800mm wide roller. The products for passenger vehicles, light commercial vehicles and heavy-duty freight vehicles are based on the motor-in-the-middle principle. These use also cradle-mounted asynchronous motors which are arranged between the rollers. Along with a reduction in required space, the advantage of this design is the low power dissipation and high torsional rigidity. AVL ROADSIM 48’’MIM is available in two roller widths (distance between outer roller edges 2,300mm and 2,744mm) and two performance classes (150kW and 220kW) for front-wheel, rear-wheel and all-wheel drive passenger and light commercial vehicles. AVL ROADSIM 72’’MIM is designed for the testing of stateof the-art freight vehicles up to 20 tonne axle load. It is equipped with a distance between outer roller edges of 3,000mm as well as a robust 450kW asynchronous motor-in-the-middle design for each axle. This compact design combines robust with highly precise testing of high-torque freight vehicles. Planning, consultation, and implementation of system solutions for vehicle testbeds
