    EU launches e35m driver assist programmeThe european Unions Ar-temis joint technology initia-tive has launched a three-year project to design and develop a tool platform for embedded ad-vanced driver assistance (adas) systems. Started in September, the Deserve project has the backing of car makers Daimler and Volvo.

    There are a total of 26 com-panies across nine countries involved in the project, includ-ing Bosch. Continental, DSpace, Infineon and NXP. Total invest-ment in the project is expected to be around e35m.

    The project aims to exploit the benefits of cross-domain soft-ware reuse, standard interfaces and easy and safe integration of heterogeneous modules to cope with the expected increase in function complexity. A modular system is also better placed for keeping costs down.

    Partners in the project will be looking to develop reference de-signs and architectures to create tools that can be engineered with little effort. The design methods and tools will support the intro-duction of disruptive hardware and software to allow trade-offs

    between properties such as cost and robustness.

    Cost is important because one of the goals of Deserve is to make adas affordable in the low-end car market.

    The sharing of software and hardware resources will enable higher levels of complexity to be taken into consideration without a proportional increase in the price of the modules and the vehicle, said a statement from Deserve. Fast and signifi-cant market penetration will be promoted through relevant cost reductions and Europes posi-

    Car thieves caught by mesh networkSince iTS launch in March, Trackers mesh network has led to the recovery of more than 4m of stolen vehicles. The net-work uses vehicles fitted with SVR units to identify stolen ve-hicles also fitted with Tracker.

    This brings drivers together to create a nationwide network of listening vehicles.

    Our latest figures show the success of the Tracker mesh net-work, with well over 4m of sto-len vehicles recovered using this

    new vehicle crime detection sys-tem, said Stephen Doran, man-aging director of Tracker. Cru-cially, the Tracker mesh network empowers drivers by allowing their cars to be used as detec-tion devices to help police and Tracker combat vehicle crime.

    When a vehicle fitted with Tracker Locate or Plant passes any Tracker SVR equipped vehi-cle that has been reported stolen, it automatically sends a signal with the location of the stolen

    tion as a key player in the adas market will be strengthened.

    Deserve aims to create a Eu-ropean standard including me-ta-models, methods and tools for safety-critical hard real-time adas development. It should pro-vide an environment for design, development, pre-validation and even pre-certification of software and hardware for adas applications.

    The project acknowledges that multi-core architectures will have to play a key role to reach the necessary levels of perform-ance and safety.

    When two is better than oneThis underground car park has provided a good example of how well Aptinas image coproc-essors work in automotive camera applications. The image on the right shows the building as captured using the firms AP0100AT image coprocessor and AR0132AT megapixel HDR (high dynamic range) sensor. The sensor performance is improved because the heat is lower when using a separate coprocessor chip. Our automotive OEMs need to deliver multiple camera products quickly and efficiently, said David Zimpfer, vice president and general manager for Aptinas automotive business. Meeting this challenge, Aptina created an advanced, flexible two-chip solution that combines megapixel resolution sensor support, superior image quality including HDR, and optimal heat dissipation.

    The AP0100AT and AP0101AT co-processors provide colour processing, auto-function support, noise reduction and adaptive local tone mapping to enhance HDR images. The AP0101AT is for digital surround view systems and the AP0100AT supports 185 fisheye lens distortion correc-tion, perspective correction and multiple view options such as split side view and triptych.

    car even if it is hidden in a ga-rage, container or underground car park. Both drivers are totally unaware that the stolen vehicle has been identified.

    Ninety per cent of stolen cars fitted with Tracker are returned to their owners and 80% of these are recovered within 24 hours, said Doran. But with the mesh networks ever-expanding web, designed to catch car criminals, we hope to recover more vehi-cles faster than ever.

    Cantata 6.2 shines at AAEQa SySTemS chose the Ad-vanced Automotive Electronics (AAE) conference and exhibition (see page 12) for its first show-ing of version 6.2 of its Cantata unit and integration testing tool for C/C++ embedded systems.

    Including more than 30 sepa-rate enhancements and over 40 fixes, Cantata 6.2 has been spe-cifically developed to simplify, further automate and speed up the software testing procedure. Cantata 6.2 is now also available as a complete built-on Eclipse development environment or as a set of Eclipse-ready plug-ins supporting the most recent four Eclipse releases.

    Since our acquisition of the Cantata++ product line from IPL in March 2012 and our subse-quent rebranding to Cantata, we have been working hard at developing the product to suit the immediate business needs of software developers, said Andreas Sczepansky, CEO at QA Systems. Specific industry sec-tors such as aerospace or trans-port have very precise standards that absolutely must be met for business critical and safety criti-cal systems, making testing a fundamental activity within any software development.
