   <abstract xml:lang="ru">
    <p>В статье представлена усовершенствованная аналитическая модель для расчета пороговой скорости наступления полного аквапланирования одиночного колеса легкового автомобиля. Отличительной чертой подхода выступает последовательное уточнение геометрических параметров водяного клина (угла атаки и площади смоченной поверхности) и детализированное описание гидравлического сопротивления дренажных канавок протектора с применением непрерывной формулы Черчилля для коэффициента трения, справедливой во всем спектре чисел Рейнольдса — от ламинарного до развитого турбулентного течения, включая переходную область. Такой прием избавляет от необходимости априорного выбора расчетного режима и обеспечивает гладкую функциональную связь критической скорости с исходными параметрами. Потери на входе в канавку рассчитываются по классической гидравлической схеме — через скоростной напор в узком сечении, а движущий перепад давления принимается равным полному динамическому напору набегающего потока. На базе предложенной модели разработано алгоритмическое обеспечение для проактивного управления движением беспилотных автотранспортных средств в составе интеллектуальных транспортных систем. Определены состав и назначение бортовых сенсорных подсистем, необходимых для получения исходных данных в реальном масштабе времени. Приведен числовой пример, демонстрирующий сходимость итерационной процедуры, и выполнено сопоставление с известными инженерными методиками.</p>

    <p>this article presents an improved analytical model for calculating the threshold speed for the onset of full hydroplaning of a single wheel on a passenger car. A distinctive feature of this approach is the consistent refinement of the geometric parameters of the water wedge (angle of attack and wetted surface area) and a detailed description of the hydraulic resistance of the tread grooves using the continuous Churchill formula for the friction coefficient, which is valid across the entire spectrum of Reynolds numbers — from laminar to fully developed turbulent flow, including the transition region. This approach eliminates the need for an a priori selection of the design mode and ensures a smooth functional relationship between the critical speed and the initial parameters. Losses at the groove entrance are calculated using a classical hydraulic model — using the dynamic pressure in a narrow cross-section, and the driving pressure difference is assumed to be equal to the full dynamic pressure of the oncoming flow. Based on the proposed  model, algorithmic support has been developed for proactively controlling the movement of unmanned vehicles as part of intelligent transport systems. The composition and purpose of the onboard sensor subsystems required to obtain initial data in real time are determined. A numerical example demonstrating the convergence of the iterative procedure is presented, and a comparison with known engineering methods is made.</p>
