Pre-Crash Performance of Collision Mitigation and Avoidance Systems: Results from the Assess Project

Abstract

Integrated vehicle safety systems that combine elements from primary and secondary safety have a high potential to improve vehicle safety, due to their ability to influence crash conditions and/or to adapt to these crash conditions. So far no standard evaluation procedures have been developed and implemented. The main goal of the ASSESS project is to develop harmonized and standardized assessment procedures for related collision mitigation and avoidance systems. Procedures are developed for:• Driver behavior evaluation • Pre-crash system performance evaluation • Crash performance evaluation • Socio-economic assessment This paper presents the activities related to the "Pre-Crash evaluation". The objective is to provide a tool box for the specific evaluation of the pre-crash performance of collision mitigation and avoidance systems and their contribution to the overall system performance.

Towards an Ontology for Scenario Definition for the Assessment of Automated Vehicles: An Object-Oriented Framework

“…• scenarios provide the basis and justification for the tests used for the scenario-based assessment [4], [6], [12]- [15],…”

“…• it helps to arrive at an unambiguous description of scenarios that is crucial for providing standardized, repeatable, and reproducible tests [12],…”

“…The notion of scenario is frequently used in the context of automated driving (Pütz et al, 2017;Gietelink et al, 2006;Hulshof et al, 2013;Ebner et al, 2011;Ploeg et al, 2018;Zofka et al, 2015;Xiong and Olstam, 2015;Shao et al, 2019), despite the fact that an explicit definition is often not provided. However, as mentioned by various authors (Stellet et al, 2015;Helmer et al, 2017;Alvarez et al, 2017;Zofka et al, 2015;Aparicio et al, 2013;Pütz et al, 2017;Geyer et al, 2014;Ulbrich et al, 2015), using a scenario in the context of the development or assessment of AVs requires a clear definition of a scenario. To this end, some definitions of a scenario in the context of (automated) driving have been proposed in literature (Geyer et al, 2014;Ulbrich et al, 2015;Elrofai et al, 2016).…”

Validation and Optimization of Suspension Design for Testing Platform Vehicle

“…e testing target vehicle, named ASSESSOR, that was developed by companies such as Daimler and Bosch has good collision tolerance and can withstand 200 impacts at a speed of 50 km/h, but it can only be used for static test and cannot meet the requirements of the testing scenario [8]. In view of this, IDIADA's testing target vehicle [9] has been subject to corresponding improvements. e testing target vehicle is suspended on the boom fixed on the tractor, so it has dynamic performance and has the advantages of speed accuracy and easy control of the lateral offset.…”
