Driver assistance and safety systems are important growth components for car makers today and into the future. Forward-looking trends such as Green Driving (energy efficient), Safe Driving and Autonomous Driving necessitate the need for intelligent vehicles. The demand for cars that watch, communicate, think, respond to driver’s needs and their surrounding elements are increasing. EB (Elektrobit) provides driver assistance software solutions, ranging from out of the box products for development, validation and measurement to engineering services for integration and maintenance of modules and components.

EB Assist ADTF (Automotive data and time-triggered framework)
A tool for the development of driver assistance functions in the car. It’s system provides open interfaces such as CAN. With the platform independent software development kit (SDK) driver assistance functions can be implemented. Additionally, the framework protects the user’s intellectual property by providing the option to exchange software components in binary form. Also it is able to capture and synchronize data from multiple, different sensor sources and provides components for data recording and interpretation of CAN, LIN, Most, Flexray and Ethernet bus systems. Besides data recording, the framework offers tools for real-time data playback, data handling, processing and visualization in the lab as well as in the test car. To support data exchange with proprietary tools, a streaming library is available. The product is suitable for application fields such as adaptive cruise control, driver drowsiness detection, lane departure warning, adaptive light control, traffic sign recognition, blind spot detection or night vision.

Driver assistance systems and the tests required to develop and validate them are becoming more and more complex in today’s connected world. As a result, an ever-increasing number of test drives are needed. EB has developed a technology to help car makers test complex driver assistance systems. The company's EB Assist Car Data Recorder is a measurement tool that allows product development engineers to record and visualize data during test drives using a tablet computer without complicated cable installations, monitors or keyboards. Easy-to-read graphics and tablet displays help engineers focus on test-drive essentials, minimizing evaluation and data-acquisition errors and increasing overall test efficiency.

"The market for driver assistance systems is growing rapidly," says Martin Schleicher, Vice President of Strategy of EB's Automotive Business Segment. "Driver assistance systems and the tests required to develop them are becoming more and more complex in today's connected world. As a result, an ever-increasing number of tests and product-development test drives are needed. Today's market is urgently in need of intuitive, flexible and cost-effective road-test solutions such as EB Assist Car Data Recorder."

The tablet’s "plug & play" functionality and its wireless connection reduce driver distraction and the amount of time required for mounting and dismounting laptops and displays. Test-drive scenarios can be changed during testing and engineers are able to move more freely in and around the car.

"Development work on EB's Car Data Recorder began more than one year ago in cooperation with a number of leading car makers and automotive suppliers", Schleicher noted.

The EB Assist CDR is based on EB's platform for developing and testing advanced driver assistance systems – the EB Assist ADTF But it is designed to be used at the desktop. EB Assist CDR transfers and extends the functionality of the EB Assist ADTF. The EB Assist CDR allows data exchanges between ADTF-based test cars and development systems and also offers a variety of out-of-the-box tools and components, including support for various vehicle busses such as CAN, Flexray and Ethernet, as well as to other hardware devices. According to the company the recorder provides instant feedback.

"The requirements for testing are growing continuously and there is an increasing demand for standardized, more user-friendly test and measurement equipment applications", says Dr. Matthias Gebhard, Head of Metrology for Driver Assistance and Optical Metrology Systems at Porsche AG. "We have had an opportunity to have a first glance at EB's Car Data Recorder. It is a clever product that offers exactly the features our test engineers have been asking for."

Jürgen Ludwig, Driver Assistance Business Development at EB notes that "besides its cost-effectiveness, reliability and scalability, based on standardized platforms and systems like ADTF and iOS, the EB Assist CDR also provides unrivalled usability. The user interface offers a wide range of highly customizable visualization options for a clear and intuitive illustration of highly complex features. The EB Assist Car Data Recorder can be used for test scenario from highly specialized developer applications to live test-result presentations for senior management." Ludwig predicts.
