What are Advanced Driver Assistance Systems?
Driver assistance systems (acronym: ADAS) are electronic compenents in vehicles. They do the following:
Assist the driver
Improve convenience and economy
A crucial factor for success is full detection of the car's surroundings with all relevant objects. This includes reliably predicting how a traffic scenario will develop. Different sensors acquire the vehicle's surroundings, and the sensor data is then analyzed and merged in the ECUs.
Challenges in the development of ADAS
Large quantities of data from different sensors such as radar, lidar, ultrasonic, laser and video-based systems must be visualized and validated. Fundamental tasks in ADAS development are:
Developing multisensor applications
Sensor data fusion
Design of probabilistic algorithms
Integrating image processing
Automated evaluation of large quantities of data
Quick access to internal ECU data
Integrating ECUs into a network

Data from a wide range of sensors must be recorded and transmitted synchronously. By means of the sensor data fusion, one obtains a complete picture of the vehicle environment.
Data Recording for ADAS Development
The automotive industry is working extremely hard on technologies for autonomous driving. To replace human perception of the environment, the use of driver assistance systems with high-resolution radar and video sensors is essential. Massive quantities of data that need to both be transported via the communication networks as well as processed in real-time are thereby generated. This creates challenges in an unprecedented dimension on recorder solutions as well. When selecting a suitable system, a number of important aspects must therefore be taken into account.
By using recorder solutions with consistently scalable architecture, developers of driver assistance systems obtain very flexible systems that can be expanded to a nearly unlimited extent. The data rates of 500 to 700 MByte/s required in current autonomous driving projects for the storing of radar, video and ECU data can still be managed at the present time with just a single PC. As requirements increase, investment security is ensured by the VX1000 hardware – which can be used for both ECUs as well as for raw sensor data – and by the scalability of the complete solution.
The complex hardware and software environment for autonomous driving raises the question of how release processes for this systems can be designed.
Combining Forces for ADAS Testing – Skillful Use of the Toolbox
When heading at full speed into the new ADAS world, it is better if there is no risk to any of the parties involved. How do we handle the current IT paradigm change in a way that makes the testing of all the functions truly reliable? Do we need more complex or completely different tools? Or would the skillful use of existing tools be a suitable approach?

Virtual Model-In-The-Loop Test for the Development of Driver Assistance Systems
Due to the ever-increasing complexity of driver assistance functions, combined with the integration and fusion of different sensors, it is necessary to evaluate the performance of those systems as early as possible in the development cycle. Ideally, this is done automatically and already during the modeling phase. If vehicle dynamics influences the detection performance of the sensor system, or limiting cases need to be taken into account, the test system also needs to be able to test the Device Under Test (DUT) in a closed-loop. Having appropriate, application-specific metrics – especially for the validation of data fusion – is another requirement. The case study shows a solution based on tools from TASS, BASELABS and Vector.
The Challenge: Evaluating data fusion and driving functions early in the development cycle
The Solution: Automated testing of the models of algorithms and functions in virtual environments
