Energy Consumption Evaluation Method for Heavy-Duty Trucks on Actual Roads Based on Driving Characteristic Interval Division
摘要
Abstract
During the actual road driving test process,strictly controlling the driving state of heavy-duty trucks can be challenging,which makes it difficult to directly evaluate the energy consumption levels from the test results.Therefore,this paper proposes an energy consumption evaluation method based on the division of driving characteristic intervals.Firstly,by analyzing the distribution characteristics of test points in the China Heavy-duty Commercial Vehicle Test Cycle for Truck(CHTC-HT),a division scheme for the number and boundaries of speed and acceleration intervals for heavy duty trucks is proposed.Then,considering the impact of road slope,the actual road test data is filtered and used to calculate the average fuel consumption across different driving characteristic intervals.Finally,based on the cumulative driving mileage within each interval of the CHTC-HT,the energy consumption evaluation results are obtained.The validation is conducted using three chassis dynamometer drum tests and two actual road driving tests.The results show that the proposed method improves the reproducibility of actual road energy consumption evaluation results for heavy-duty trucks.关键词
