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. The value of pre-crash sensing systems that employ remote exterior sensors (in combination with on-board sensors) to detect dangerous situations and activate primary and secondary safety devices was clearly shown in projects like TRACE, APROSYS, eIMPACT and SAFETY TECHNOPRO. Joint R&D efforts (e.g. PReVENT, CHAMELEON, SAVE-U) have resulted in Pre-Crash Safety systems that are already on the market or close to market introduction.
In previous and current projects, the development of test and evaluation procedures was considered to be merely a secondary objective. So far, no procedures have been developed and implemented. Moreover, all the research into test procedures was based on research systems and not on commercially available systems.
Because of the above, a project specifically devoted to the development of assessment procedures is required to enable widespread introduction of integrated vehicle safety systems such as pre-crash sensing systems into the vehicle fleet. The main goal of the ASSESS project [1] is to develop harmonized and standardized assessment procedures and related tools for commercially available pre-crash sensing systems. Procedures will be developed for:
This paper will present the activities related to the “driver behavior evaluation”. The objective is to provide a tool box for the specific evaluation of behavioral aspects of pre-crash systems and the contribution of the overall system performance.
The paper will include the complete test design: test scenarios, measurements, key performance indicators (objective/subjective data) and questionnaires. In addition, needs of behavioral aspects for “system performance evaluation” in test tracks will be discussed (e.g. driver reaction times).
The following aspects will be investigated and taken as a first approach towards assessment criteria:
In order to carry out the experimental studies in driving simulators (6D moving based) and tests tracks with real vehicles and subjects, a common and harmonized test design, including the complete story book, will be presented. Possibilities and limitations of the methods will be also discussed.
This paper summarizes the results corresponding to the stability assistance domain of the European project ASSESS (Assessment of Integrated Vehicle Safety Systems for improved vehicle safety, FP7 – SST 2nd call, grant agreement no. 233942)
