Future Testing of Active Safety Systems

Abstract

Active safety systems are increasingly becoming available in trucks and passenger vehicles. Developments in the field of active safety are shifting from increasing driver comfort towards increasing occupant safety. Furthermore, this shift is seen within active safety systems: safety functions are added to existing comfort systems, rather than adding new safety systems to the vehicle. Comfort systems such as cruise control are extended via ACC to pre-crash braking systems. Testing of active safety systems must follow these developments. Whereas standardized test programs are available for passive safety systems, such test programs are hardly available yet for active safety systems. Furthermore, test programs for passive safety systems consist of only a handful of scenarios. Test programs for active safety systems, however, should consist of much more scenarios, as those systems should function well in many different situations. It is not feasible to assess the intelligent vehicle safety (IVS) system's performance in all these scenarios by means of testtrack testing. To speed up the introduction of active safety systems, there is a need for an efficient standardized test program, including alternatives to test track testing. This paper describes the vision of TNO Automotive on the developments that are expected in the field of development and evaluation of active safety systems and it explains the need for an efficient and complete test program for IVS systems, consisting of simulations, hardware-in-the-loop simulations and test track testing.

Calibrating trust through knowledge: Introducing the concept of informed safety for automation in vehicles

“…As discussed in section 1.1.2, the identification of failures helps classify them as "good failures" as it provides a level of predictability about them and thus do not have a detrimental effect of trust (Lee and See, 2004). However, knowledge creation about the capabilities and limitations of ADAS and AD systems faces reliability challenges (Khastgir, Birrell, Dhadyalla, Sivencrona, et al, 2017) and validation challenges which include challenges in test methods and test setup (Hendriks, Pelders and Tideman, 2010;Khastgir et al, 2015;Yu, Lin and Kim, 2016). While the authors consider knowledge creation as an important part of the process of development of trust, it remains out of scope of this paper and will be discussed in future publications.…”
