Abstract
Introduction (statement of the problem and relevance). The available methods for testing automatic emergency braking systems (AEBS) do not take into account the specific features of Russian operating conditions (lighting, weather conditions, real traffic accidents statistics (RTAS), etc.). Therefore, reasonable adaptation and correction of such methods is of necessity.The purpose of the study was to develop and test an AEBS effective methodology to prevent a collision with a pedestrian.Methodology and research methods. The methods of statistical research data and mathematical analysis of road accidents have been applied. Based on the traffic accidents pedestrian collision statistics in 2020, the most common scenarios and pedestrian collision causes in the Russian Federation were determined. Considering these data different types of automatic emergency braking systems (AEBS) tests including the function of preventing collision with pedestrians were proposed. AEBS tests were planned to be carried out in daylight and at night without artificial lighting.Scientific novelty and results. The scientific novelty of the research is an AEBS system effectiveness assessment when working on “adult pedestrian”. The criterion for evaluating AEBS effectiveness was the maximum speed at which it was possible to prevent a collision with a pedestrian. The final assessment of the action effectiveness was determined when the weighting factor of each type of test was taken into account. The weight coefficients were substantiated by real accident statistics. The results of AEBS testing efficiency for a Toyota RAV4 car, performed according to the developed methodology, have been presented. A parametric record of the field test characterizing the features of the Toyota RAV4 AEBS functioning has been presented as well.Practical significance. The developed methodology can be taken as the basis for the formation of the Russian national safety rating for new vehicles RuNCAP.
