文摘

The article is devoted to investigation of some operational factors affecting the response time of a brake system and substantiation of the need for their consideration in reconstructing and investigating traffic accidents. The aim of this article is to publish proposals for improving the traffic accidents (TA) assessment methodology by considering extra operational factors that increase the braking time and the length of stopping distance of a vehicle fitted with a hydraulic brake drive. Experiments have proved that there is regularity in influence of the braking fluid boiling temperature on the total braking system response time. A coefficient has been calculated and substantiated that takes into account this influence on designed braking time values and vehicle stopping distance.
