APPLICATION Owing to their high accuracy and availability, these systems are used all over the world for emission certification and vehicle development all over the world. This family of products can also be used in the fields of: • Exhaust gas emission and endurance tests • Use in SHEDs for the testing of vehicle emissions • Climatic and height 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 allows for real and dynamic vehicle design and chassis modeling • Comprehensive vehicle testbed designs meet all customer requirements for axle load, performance, mass simulation quality, ease of use and extensibility • High levels of torsional rigidity in combination with the AVL Controller allow for torque vectoring tests of state-of-the-art powertrain systems (significantly better than 0.02 km/h in synchronous operation) The increasing complexity of powertrain management systems and the close interaction of engine and transmission control units (ECU and TCU), in combination with emission regulations, often requires 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 400 mm wide roller via a connectible roller up to a 1 800 mm wide roller. The products for passenger vehicles, light commercial vehicles and heavy-duty freight vehicles are based on the mid-engine principle. These are also cradle-mounted asynchronous engines 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 axle widths (2 300 mm and 2 744 mm) and two performance classes (150 kW and 220 kW) for front-wheel, rear-wheel, and all-wheel drive passenger vehicles and light commercial vehicles. AVL ROADSIM 72’’MIM is designed for the testing of state-of-the-art freight vehicles up to a 20 t axle load. It is equipped with an axle width of 3 000 mm as well as a robust 450 kW asynchronous mid-engine for each axle. This compact design combines the robust and highly Planning, consultation, and implementation of system solutions for vehicle testbeds
