摘要
针对目前旅游出行,新能源客车存在动力性能不足及续航里程焦虑问题,本文基于某城市客车匹配出一款增程式客车。根据目标任务需求、工作场景、整车驱动结构布置和行驶动力性能等,对客车增程器系统、驱动电机及动力电池进行参数匹配计算。利用AVL-CRUISE软件搭建整车模型、设置仿真任务并验证了匹配的合理性,结果表明:在中国普通客车行驶工况(CHTC-C)下车辆运动跟随情况良好、客车最高车速达到99 km/h、0~50 km/h加速时间为17.99 s较指标要求提升21.78%、最大爬坡度20.8%、续航里程为692 km相比指标要求提高了38.4%,各方面均达到指标要求。
In view of the current tourism travel, new energy buses have insufficient power performance and cruising range anxiety, and this paper matches a range extension bus based on a city bus. According to the target task requirements, working scenarios, vehicle drive structure layout and driving pow-er performance, the parameters of the bus range extender system, drive motor and power battery are matched and calculated. The AVL-CRUISE software was used to build the vehicle model, set the simulation task and verify the rationality of the matching, and the results showed that the vehicle motion following was good under the Chinese ordinary bus driving condition (CHTC-C), the maxi-mum speed of the bus reached 99 km/h, and the acceleration time of 0~50 km/h was 17.99 s, which was 21.78% higher than the index requirements, the maximum climbing degree was 20.8%, and the cruising range was 692 km, which was 38.4% higher than the index requirements. All as-pects meet the target requirements.
