Троллейбус – вид городского общественного электрического транспорта, который рассматривается как перспективный инструмент для повышения эффективности общественного транспорта и достижения целей устойчивого развития и качества жизни в городе. Управление в троллейбусе работой тормозной системы – рабочей и вспомогательной (тормозным моментом тягового электродвигателя) – осуществляется с помощью одной педали. Таким образом, имеются режимы совместной работы этих систем в процессе торможения. Основное внимание автор сосредоточил на разработке алгоритма для совместного управления тяговым электродвигателем и антиблокировочной тормозной системой для повышения общей эффективности торможения транспортного средства. С этой целью разработана математическая модель динамики торможения троллейбуса. Для определения параметров эффективности торможения автомобиля и проверки математической модели проведены стендовые и дорожные испытания на различных дорожных покрытиях. Соответствующие экспериментальные данные использовались для анализа эффективности предложенной стратегии совмещения управления тяговым электродвигателем и антиблокировочной тормозной системой троллейбуса. В результате подтверждена дееспособность предложенного алгоритма управления, обеспечивающего требуемую эффективность торможения и высокую тормозную устойчивость автомобиля.</p></abstract><trans-abstract xml:lang="en"><p>The widespread use of green public transport is a priority strategy to reduce a congestion and pollution from road traffic in many cities. The trolleybus is a type of urban public electric transport, which is considered as a promising tool for  increasing the efficiency of public transport and achieving the goals of sustainable development and quality of life in the city. The operation control of service brake system and secondary brake system (braking torque of traction electric motor) is realized with the help of one pedal in the trolleybus. Thus, there are modes of joint operation for these systems during the braking process. The author has focused his main attention on the development of an algorithm for blending control of the traction electric motor and the anti-lock braking system to enhance the overall braking efficiency of a vehicle. For this purpose, a mathematical model of the trolleybus braking dynamics has been developed. Bench and road tests have been carried out on various road surfaces to determine parameters of vehicle braking efficiency and to validate the developed mathematical model. The corresponding experimental data were used to analyse the efficiency of the proposed strategy for combining the blending control of traction electric motor and anti-lock braking system of the trolleybus. As a result, the efficiency of the proposed control algorithm has been confirmed, which provides the required braking efficiency and high braking stability of the vehicle. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>троллейбус</kwd><kwd>антиблокировочная тормозная система</kwd><kwd>противобуксовочная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>trolleybus</kwd><kwd>anti-lock braking system</kwd><kwd>traction control system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Environmental Protection UK.
