The study of the maneuver of a braked vehicle in analyzing the bypassing of a stationary obstacle

Abstract

This article discusses the maneuvering of a braked vehicle equipped with an Anti-lock Braking System (ABS) in analyzing the bypass of a stationary obstacle, as a study of the technical aspect of the mechanism of traffic accidents. Using the developed mathematical model, criteria for safe bypassing of obstacles were established, taking into account the dimensions of the vehicle, its speed at the start of the maneuver, the condition of the road surface, as well as the parameters of the obstacle (width and distance to it). An important part of the study is considering the reduction of the car's speed due to braking, which significantly affects the dynamics of the maneuver.

The article provides a detailed description of the algorithms for analyzing the mechanism of traffic accidents, depending on the tasks set before the expert. Based on the obtained data, conditions for the safe bypass of obstacles for different types of maneuvers: "entering a turn," "entry-exit," and "lane change" are formulated. Algorithms for solving typical tasks that may arise during the conduct of forensic automotive technical expertise are also proposed, with particular attention paid to establishing the driver's technical ability to avoid collision with a stationary obstacle, as well as checking the technical capacity of the participants' statements in such type of traffic accidents.

In the concluding part of the article, prospects for further research are discussed, including the need for experimental testing to establish empirical dependencies used in the developed mathematical model. The advisability of expanding the subject of expert research on the obstacle bypass maneuver is also expressed.

This work is significant for improving the methodologies of forensic automotive technical expertise and developing effective algorithms for analyzing the mechanism of road traffic accidents related to collisions with stationary obstacles, which also contributes to the development of measures to prevent accidents on roads, ensuring greater road safety.
