Введение (постановка задачи и актуальность). В дополнение к испытаниям на динамометрическом стенде, начиная с уровня Евро-6d, испытания автомобиля в реальных дорожных условиях (RDE) являются обязательными. В качестве критериев при валидации испытания используются динамические параметры движения автомобиля, такие как относительное позитивное ускорение (υ ∙ аpos) [95], а также удельные выбросы СО2 при помощи метода «скользящего окна усреднения».

Цель работы – сравнение динамики движения автомобиля по двум дорожным маршрутам и оценка пригодности маршрутов для испытания автомобиля по Правилам ООН № 168 на основе анализа динамических параметров движения.

Методология работы

Методология работы. Обзор параметров движения автомобиля. Испытания автомобиля, разработанного во ФГУП «НАМИ», в реальных дорожных условиях по двум маршрутам, расположенным в разных регионах. Обработка и анализ результатов.

Результаты и научная новизна. Представлен обзор развития испытательных ездовых циклов и научного подхода для их оценки при помощи динамических параметров движения. На основе анализа динамических параметров показаны особенности движения автомобиля по двум маршрутам. Выявлено кратное отличие значений динамических параметров друг от друга при движении по разным маршрутам из-за разных дорожных условий на них. Показано, что движение автомобиля по RDE-маршрутам по сравнению с движением в ездовых циклах NEDC, WLTC характеризуется значительно более высокими ускорениями и динамическими параметрами движения.

Практическая значимость

Практическая значимость. Продемонстрирована пригодность RDE-маршрутов для проведения испытаний по Правилам ООН № 168. Результаты представляют практический интерес для испытательных лабораторий, для производителей автомобилей, систем очистки отработавших газов, а также могут быть использованы при определении государственной политики в области снижения выбросов загрязняющих веществ автомобильным транспортом.

Introduction (problem statement and relevance). In addition to testing on a chassis dynamometer, starting from the Euro-6d level, vehicle testing under real road conditions (RDE) is mandatory. Vehicle driving dynamic parameters such as relative positive acceleration (υ∙ аpos) [95], as well as specific CO2 emissions are used as criteria in the test validation using the moving averaging window method.

The purpose of the study is to compare vehicle driving dynamics on two road routes and assess the suitability of the routes for vehicle testing according to UN Regulation No. 168 based on analysis of dynamic driving parameters.

Methodology and research methods. Review of vehicle driving parameters. Testing of the vehicle developed in FSUE “NAMI” under real road conditions on two routes located in different regions. Processing and analysis of results.

Scientific novelty and results. An overview of development of test driving cycles and scientific approach for evaluating them using dynamic driving parameters is presented. Based on the analysis of dynamic parameters, specific features of vehicle driving on two routes are shown. A multiple difference in the values of dynamic parameters is revealed when driving on different routes due to different road conditions on these routes. It is shown that vehicle driving on RDE routes is characterized by significantly higher accelerations and dynamic driving parameters compared to driving in the NEDC and WLTC driving cycles.

Practical significance. Suitability of RDE routes for testing according to UN Regulation No. 168 is demonstrated. The results are of practical interest to testing laboratories, manufacturers of vehicles, exhaust gas aftertreatment systems, and can also be used in determining government policy in the field of reducing emissions of pollutants by road transport.
