We at Veoneer not only intend to encourage It is a challenging remit, yet a necessity, for at least two reasons: only to learn from this new conversation but help lead its realization. First, as MIT’s Advanced Vehicle Technology Research shows, consumers lack the core mental other vehicles, the A collaborative model of designers and a myriad of conditional operating conditions don’t offer the support needed infrastructure and safety learning for successful technology adoption.

Usability of safety PART II: technology will be as important as its Scalable availability Safety Second, in order to build up and then apply the amount of information needed for realizing this new vision for safety, sensor data from all vehicles need to be leveraged, and the resulting data merged with other sources of information on the localized context. This will be accomplished by securely feeding relevant data to the cloud, where risks can be understood and profiled. Such risks can be related Applying safety capabilities It starts with a to driver behavior, like understanding individuals’ tolerances for car-following and, thereupon, will be as important as modular system determining based on vehicle dynamics the opti- innovating new ones architecture mum timing for driver warning (or not).

The aviation industry learned over 30 years ago that a philosophy of ’replacing’ the disposal, they can operator has fundamental flaws. Aviation work on automation not only focuses on leveraging human expect to encounter performance and approaches to minimize errors. It also emphasizes the need to keep operator skills more situations when they must consider, up-to-date, partly by education, partly by making sure pilots are still able to fly manually, and partly through strategically developed human centered automation. or have embraced and We think it’s no different for automotive techno- logies.

These questions become tangibly real for drivers of cars equipped with advanced systems. Millions of drivers over the next 10 years will not only have to ask what their vehicle is able to handle, but be prepared and comfortable answering them with literal life-or-death certainty. We at Veoneer see not just the opportunity but the necessity of helping them. Democratizing safety technology so that it benefits the greatest number of people as soon as possible is a new way of looking at our journey to full automotive autonomy. We believe that such a development can be enabled by a scalable safety approach that puts each new safety innovation wherever it can work effectively. In pursuing this vision, we will build a context of trust on our journey to 2030 and beyond. 14
