AVL is the world's largest independent company for the development, simulation and testing of powertrain systems.
AVL Powertrain Engineering is an expert partner to the global automotive and mobility industry for the development of innovative powertrain systems. From diesel engines to electric drives, from alternative fuels to control software, from transmissions to batteries, we have been working in partnership with companies all over the world for more than 60 years. Unique synergies with AVL Instrumentation and Test Systems and AVL Advanced Simulation Technologies enable the development of highly creative, mature and application-specific solutions to enable our customers to meet their future market challenges.
Powerful multi-dimensional simulation platforms developed on the basis of AVL's engineering knowledge guide you to practical, application oriented solutions.
Controls are a key characteristic to differentiate the behavior of the powertrain in regards to vehicle performance, emissions, robustness of diagnostic and brand style (Brand DNA). AVL can deliver independent and modular powertrain software control solutions from prototype through to production to meet individual customer demands.
To handle the increasing complexity in combustion engine development and avoid costly recalls, OEMs need advanced tools and smart testing methods that consider the manufacturing and assembling process. At AVL, we have the skills, experience and know-how to meet these challenges head on. Our deep understanding of the test mechanism and our leading system experience is second to none. AVL’s test systems and cutting-edge solutions for all sectors, such as light-duty, mid-duty and heavy-duty engines complete the portfolio. Our end-of-line solutions feature container systems that can be easily integrated into any existing production environment. At AVL, we take pride in being a reliable partner that delivers testing technologies for production, that combine a high degree of flexibility with precision and quality at the highest level. Examples for supported standard solutions include: End-of-Line Loaded Hot Test Systems Quality Audit (QA) / Conformity of Production (COP) Systems Qualified Hot Test Systems End-of-Line Engine Cold Test In-Process Verification Test System (IPV) AVL Guarantees Turnkey systems that suit each application and customer requirement Huge experience thanks to numerous turnkey projects globally Consistency between AVL test systems with our Integrated and Open Development Platform. High-precision measurements with reproducible results
The development of modern vehicles with extremely complex powertrain concepts puts high requirements on new development and validation methods with the associated tools. In order to save costs and reduce development times, road tests are increasingly being transferred to vehicle testbeds and replaced by simulation. Transferability and a balance between the individual test environments (off-line simulation, hardware-in-the-loop, component testbed, vehicle testbed, road, etc.) must be guaranteed.
Motorcycles and all kinds of power products as well as recreational products used on water, air and solid ground demanding best suitable technology and perfect quality but still at highly attractive cost.
GNSS signals (for example GPS signals) are of major importance for positioning and tracking, orientation and safety-related information, such as congestion, in road traffic. A collaboration between AVL and Rohde & Schwarz, two of the world’s leading providers of measuring and automotive testing systems, now permits the reproduction of realistic GNSS reception conditions for testbed vehicle testing. As a result, users can reliably test all aspects of GNSS-based vehicle positioning – a core functionality of autonomous vehicles.
AVL DRIVINGCUBE™ enables the reproducible testing of driver assistance systems and driving features for self-driving vehicles using a real vehicle within a virtual environment in a variety of different traffic situations. For that purpose, test drives are performed with a real, ready-to-drive vehicle on a chassis dynamometer or powertrain testbed. With the help of realistic virtual driving scenarios it is possible to test peripheral sensors, control systems and actuators inside the vehicle in a fully reproducible and reliable manner. Automated vehicle functions are thus sufficiently validated during development and even before testing on the proving ground.
The range of environment simulations carried out with AVL DRIVINGCUBE™ can now be extended to include GNSS signals, bringing simulation closer to reality than ever before. The vehicle’s GNSS receiver (e.g. GPS) is stimulated realistically using GNSS signals generated on the testbed. This way, technical engineers can identify exactly how sensors, automated driving features and other actuators respond inside the vehicle. The now possible GNSS-based vehicle positioning feature is a core functionality of automated driving, and the approach ensures that it is reliably tested.
For generating GNSS signals, Rohde & Schwarz GNSS stimulators are used (R&S®SMBV100B or R&S®SMW200A), which allow the generation of signals for all of the available satellite navigation systems (GPS, Glonass, Galileo, BeiDou, QZSS, SBAS) across all frequency bandwidths (L1, L2, L5). This also makes them suitable for testing multi-frequency receivers, which are playing an increasingly important role in automated driving.
Solution with added value
“In Rohde & Schwarz, we now have a strong and reliable partner for GNSS stimulation. By generating consistent GNSS signals in connection with environment simulation, AVL DRIVINGCUBE™ now provides a test system that allows users to validate GNSS-based driver assistance systems and autonomous driving features,” explains Dr.-Ing. Tobias Düser, Head of Advanced Solution Lab at AVL Deutschland GmbH. Christoph Pointner, Head of Signal Generators at Rohde & Schwarz, adds: “We are very pleased to bring our expertise in the field of signal generation to this collaboration with AVL and contribute to such an important innovation and trendsetting solution for testing automatized driving features.”
The additional GNSS stimulation makes testbed testing not only more realistic, it is above all a further step in moving testing from the road to the rig. This leads to a much sharper reduction of test drives than was the case previously and major savings in the kilometers driven.
A flexible system easily integrated
Rohde & Schwarz GNSS stimulators form a flexible, modular system that can be adapted to your requirements and is easily integrated in the AVL DRIVINGCUBE™ environment. The stimulator is controlled automatically from the simulation platform. GNSS extensions for AVL DRIVINGCUBE™ are available with immediate effect.
