Research on Multi-objective Secondary Maintenance Mileage of Hybrid Electric City Bus Drive System
ZHU Jinting,LITao,LU Anzhuan
Abstract: Through the statistics and analysis on the fault data of hybrid electric city buses, the authors establish the secondary maintenance mileage models of vehicle reliability, safety and economy objectives meeting the Weibull distribution. They weight the maintenance mileages under different targets by weight to comprehensively determine the secondary maintenance mileage, which provides a reference for the maintenance of the hybrid city bus drive system.
Key words: hybrid electric city bus; drive system; multi-objective; secondary maintenance
