Open House 2017: a Program Full of Variety
An exciting keynote will be followed by three sessions on innovations of the CarMaker product family that will be released in version 6.0 for our three areas of application Driver Assistance, Powertrain and Vehicle Dynamics. We want to show you how we constantly improve virtual test driving.
As every year, we will also honor outstanding student projects that focus on pioneering topics in simulation. In the meantime, there will be plenty of space to exchange ideas with other experts from your field since Open House has established itself as the meeting point for the virtual test driving industry.
Growing demands on systems, increasing test requirements, one solution: virtual test driving
Vehicle systems are becoming more complex and networked due to trends in vehicle development such as autonomous driving. Therefore, they can no longer be seen in isolation but need to be considered in the context of the whole vehicle. Only then can the perfect adjustment of the interaction of systems be ensured. The demands on the development process are thus growing and the calibration and validation of vehicle systems are becoming ever more complex. We are aware that the complementary use of virtual test driving in addition to real test driving saves time and expenditures in the development process and leads to a shorter time-to-market. We enable high-fidelity virtual tests of your systems under test in the context of the whole vehicle and in realistic traffic situations, allowing you to adopt the automotive systems engineering approach. Here, it is not only essential for the behavior of the virtual vehicle to correspond exactly to that of the real vehicle. The test drive also needs to be as realistic as possible.
This requires a high-fidelity representation of the vehicle’s environment which allows for scenario-based testing. If virtual test driving and real test driving are based on the same rules and can be easily transferred to one another, only then can development profit from an actual facilitation and efficiency enhancement.
Especially the development of advanced driver assistance systems relies on a realistic and reproducible representation of the vehicle’s environment. There are diverse approaches with different levels of detail for the generation of these often highly complex scenarios. The keynote speech at our Open House will provide an insight into these approaches. For efficient scenario generation, we have developed an innovative tool: the Scenario Editor of the CarMaker product family. Complex traffic situations can thus be created precisely without further expenditures for the generation of test scenarios that are both generic as well as realistic.
The Scenario Editor comprises a multitude of functions for quick scenario generation. The easy definition of road networks and the comfortable configuration of scenarios with static and dynamic objects stand out in particular. Changes to the scenario are supported by graphics and therefore comprehensible and easy to implement. In addition to the generic generation of scenarios, the import from map data (ADAS RP) or from other formats (OpenDRIVE) is possible. Data from road measurements can also be used. The Scenario Editor allows for the simple adaptation and further processing of these data.
At our Open House, use the opportunity to get to know the Scenario Editor of the CarMaker product family, which will help you generate your scenarios even more flexibly and efficiently in the future.

Driver Assistance Session: Why a Perfect Sensor Alone Does Not Make a Perfect System
Optimal testing of your driving functions with our sensor models
We are always in close contact with our clients so we know what drives them. It is our goal to keep advancing the development of sensor models in order to test sensor functions and algorithms as profoundly as possible. This also requires an environment that is as realistic as possible: the representation of the weather, the reproduction of diverse traffic objects such as parked bicycles or dumpsters that obstruct the view, or simply the time of day. We are aware of the variety of scenarios and the relevant factors. The multitude of options entails diverse challenges that we meet with a wide range of sensor models.
Virtual test driving enables you to conduct tests on various levels with appropriate sensor models:
- Ideal: Test whether your assistance function works correctly. With idealized information, common sources of errors can be precluded in an idealized environment.
- Hi-Fi: Use the sensors of this class to advance your function development. Specific technological restrictions of the sensor model enable you to test concrete applications for your function.
- RSI (Raw Signal Interface): Implement your own detection algorithms with this model. Profit from highly detailed sensor information in the development and testing of the components and signals.
Whether you wish to test an emergency brake assistant, lane keeping assistant or adaptive cruise control, on the freeway, country roads or in the city – test even complex scenarios with ease thanks to innovative sensors, detailed environment modeling and a newly developed traffic model. Is the development of automated driving functions at the top of your road map? Or would you just like to get an insight into the latest developments in the field of sensors or other methods and technologies? When it comes to driver assistance and automated driving, Open House 2017 is the place to be!
Powertrain Session: Why Real-World Driving Simulation Facilitates the Development of New Propulsion Systems
How to take real-world driving into the office and onto the test bench
New propulsion systems for vehicles need to be clean, efficient and powerful in order to meet the demands of clients and legislatures across the globe. Here, the vehicle’s behavior in specific test cycles is no longer the only focus. The issue of real-world vehicle operation is also increasingly moving into the center of attention. Our clients tell us about the difficulty of addressing this matter if the start of on-road testing is tied to the first available vehicle prototype.
In the session on powertrain at our Open House, we will demonstrate how new propulsion systems can be developed and optimized flexibly and reproducibly under real-world driving conditions by means of real-world driving simulation with virtual prototypes in the simulation on the computer and on test benches. There will be a special emphasis on the following topics:
- Real driving emissions, real-world consumption and performance: Learn about the latest features that help you transfer real routes and driving scenarios to the virtual world and get the virtual driver and vehicle up to speed for real-world driving simulation.
- Real-world driving simulation on the test bench: We present the important aspects of the technical implementation and show you how you can take all real driving resistances automatically to the test bench as well.
- Electrification: We demonstrate how partly or fully electrified vehicle concepts can be examined and evaluated in virtual test driving.
- Thermal management and cooling system development: Discover how to validate the system selection and dimensioning in real-world driving scenarios by means of model integration.
Whether you are looking for new ideas and approaches to efficiency enhancement in the development and testing of propulsion systems or just interested in gaining an overview of the latest features of our simulation solutions in the powertrain field at Open House, you won’t be disappointed! Purely electric, hybrid or conventional: Virtual test driving and the consistent use of real-world driving simulation are changing the development of propulsion systems – don’t miss out!
Vehicle Dynamics Session: Why Vehicle Dynamics Is of Central Importance for New Concepts of Mobility
How to meet the continuously growing demands for safety and comfort
For many years, engineers in the field of vehicle dynamics have been using CarMaker in their development processes to make vehicles safe and comfortable. Our software has enabled them to maintain consistent development cycles while the complexity of chassis control systems is rapidly increasingly. Until now, the primary focus has been on the gain in safety ensured through systems that electronically assist the driver.
Even though, today, autonomous driving is advanced with great effort and electric propulsion concepts are developed, vehicle dynamics continues to be the core of these technologies. For instance, if an emergency brake assist system including a collision avoidance function intervenes, it is extremely important for the dynamic behavior of the vehicle to be assessed correctly.
The driving force, however, is the vision of autonomous driving: What new challenges are developers of vehicle dynamics systems going to face if the electronic system assumes full control over the vehicle? How important is the fun of driving if all occupants become passengers and nobody fulfills the role of active driver? What are the necessary compromises in chassis tuning of vehicles that are no longer personal property but can be rented on demand by diverse groups of customers?
In the session on vehicle dynamics, new features of the upcoming release 6.0 will be presented and light will be shed on the increasing importance of vehicle dynamics simulation for the vehicle of the future.
The following will be discussed:
- Vehicle dynamics development processes using virtual prototypes
- Novel architectures of the electronic system and their influence on chassis electronics
- Resulting impacts on the simulation (MIL, SIL)
- New HIL architectures
- Innovative driving simulators for vehicle dynamics development
We are looking forward to showing you new test systems and methods, presenting the various areas of application of virtual test driving and demonstrating product innovations live. Let us start on the journey to autonomous driving with a dynamic session!
