At another of the Valeo Technical Evenings, we wtalked about testing of the autonomous systems. Whether it means public transportation or passenger cars, it is necessary to prepare them for the future and, when the time comes, only reliable transport solutions will be put into operation. The first speaker was Jan Zahradník and he talked about autonomous and highly automated cars that represent a big part of the next automotive revolution. In order to secure their safety and the effectiveness of their functionalities, these cars go through a very thorough validation regime. The regime involves collecting big amounts of data on the roads and test tracks, processing the data and extracting system performance KPIs, all the way up to system homologation and certification for certain levels of automation. In addition, virtual validation is becoming instrumental in order to train the algos and cover corner cases that cannot be safely achieved by real world testing. The combination of virtual/real world validation can cover a full range of system functionality and safety requirements including FuSa and SOTIF. The robustness of the tool chain and model correlation with real world data is key for guaranteeing the performance and reliability of the system. Defining, selecting and processing the right data becomes a big challenge with the increasing complexity of the systems and the tighter regulatory requirements. The topic of the day was narrowed down to "How to Define A Validation Methodology and Tool Chain for Level 3 and Beyond Systems" The foundations of the System Validation Platform at Valeo were: Automation, Standardization, Virtual Validation, Big Data Management, Tool Chain Validation and Advanced System Validation. Next guest was Michal Pochmon, technical director and head of implementation at Škoda Digital, who talked about the future of trams and their autonomy. He started with the recapitulation of the actual state of anticollision system in Skoda Group. We deeply analyzed the vision for the future development of the autonomous trams. The anticollision system for trams is one of the leading funcionality that is fundamental in the time of increasing density of the traffic in the bigger cities. We talked about phases and ways of testing. We did not miss the simulator and future validation possibilities. Our meet up was concluded by Tomáš Svoboda from CTU. He addressed the problem of weakly supervised learning. Complete data annotation needed for machine learning algorithms, think about labeling each pixel in images; cannot keep pace with the testing and validation demands. Instead of complete data annotation, one could leverage some external weakly related source. This talk focused on exploiting recorded vehicle trajectories. He showed how to incorporate kinematic constraints to supervise a learnable terrain predictor. In the second part, he discussed with us the ideas for incorporating a dynamic model.

PCBs became the central topic of the Valeo Technical Evening. This abbreviation, which means Printed Circuit Boards, is inextricably linked with every electronic device. Firstly, together with Miroslav Purnoch, hardware engineer from Valeo Prague R&D center, we went through the nooks and crannies of each circuit or resistor, its meaning and resulting functionality in driver assistance systems. We had a look at the steps of the development process and the tools used to design, simulate and test prototypes of printed circuit boards. What are the specifics of high frequency PCB materials for automotive radar sensors? We answered this and more on our last meetup. Later, Jiří Zvolánek presented you some of the advanced PCB technologies such as HDI microvia technology, 3D flex-rigid technology and PCBs with embedded components, on which Würth Elektronik GmbH & Co. KG works. Finally, we listened to a short introductive presentation of Valeo's PCB expert, Paul-Henry Morel, who shared a broader view of mass circuit board production. We discussed in more detail the challenges and possible future development of this discipline in the field of automotive. Jan Kostecky , the Process Engineers' Team leader, together with his colleagues gave us a 10 minutes inside look into the planned production of PCB at Valeo Rakovník Site.

How to detect the dirty sensors on a car? Algorithms for blockage detection - automotive radar and camera Has it already happened that your car showed a message like “Adaptive cruise control is switched off, radar is blocked”? Have you already thought about how important is having clear sensors that care about adaptive cruise control, lane departure warning or other smart functions in your car? And how important is it for the future autonomous cars that will not need the driver behind the steering wheel? Valeo’s department of Radars finished the development of a new algorithm that recognizes any sign of blockage of the sensor. Naiallen Carvalho, one of the developers of the algorithm, explained how it works, how a signal from the sensor looks when blocked and how to perceive if the sensor is still able to detect the objects. Valeo department of Artificial Intelligence concentrates on the dirt or water blocking cameras for a long time. David Hurych talked about how to identify the water drops on a camera lens and how the developers continue to enhance the system.

The first speaker was Martin Štěpánek, System Test engineer at Valeo. He led you into the labyrinth of cables in a car revealing their initial point and target. You got broader insight into the terms such as gateway or bus in automotive. He discussed with you how much data it is being transmitted and what kind of information they actually contain. There was also a part dedicated to the security that persuades you how you and your car are secured. The second speaker was prof. Zdeněk Hanzálek. In his talk, we concentrated on two time-triggered protocols: (1) a static segment of FlexRay (2) Qbv extension of IEEE Time-Sensitive Networking. Time-triggered systems follow the schedules obtained during the design time and satisfy timing requirements by construction. We showed several interesting problems, and we saw how algorithms found these schedules.
