基于车联网数据的混合动力汽车动力传动系统试验方法研究

Study on Test Method of Hybrid Vehicle Driveline Based on Vehicle Networking Data

为解决混合动力汽车动力传动系统耐久试验无法全面覆盖用户使用场景的问题,设计了一种基于车联网数据的用户关联正向开发方法。从用户实际典型使用工况出发,结合传动系统疲劳损伤进行规范组合开发,基于用户实际使用习惯和试验场试验载荷谱,针对将用户使用习惯转化为满足使用寿命要求的整车耐久试验规范开展了研究,确定了车辆试验场耐久试验规范的建立流程,制定了合理有效的混合动力汽车动力传动系统试验规范。

To address the issue that hybrid vehicle driveline durability test cannot cover the customers’usage scenario,a customer-relevant,forward-development method based on vehicle networking data has been designed.This paper started with typical usage conditions,combining it with analysis of driveline fatigue damage,to develop and standardize combinations.Based on the user’s driving habits and proving ground load spectrum,this study explored how to translate these users’driving habits into whole-vehicle durability test specifications that meet service life requirements.Finally,the process for establishing vehicle durability test specifications within a proving ground was determined,and a rational and effective test specifications for hybrid vehicle driveline was established.
