基于某柴电商用车的电控离合器的接合过程分析研究

Analyze and Study on the Engaging Process of Automatic Clutch based on A Diesel-Electric Hybrid Commercial Vehicle

通过分析某柴电并联混合动力轻型商用车动力系统结构以及其电控离合器的接合动力学模型,从平地起步工况和大坡度起步工况两种情况对该车电控离合器的接合过程进行了研究。在分析了控制策略的基础上,利用dSPACE/MicroAutobox将其控制模型生成快速控制原型并进行了试验。试验结果表明,所设计的控制策略既能保证正常运行工况下混合动力模式动态切换的实现,也能满足大坡度起步工况下的特殊工作要求,实现了设计目标。

By analyzing the structure of a diesel - electric hybrid commercial vehicle and the dynamic model of the automatic clutch, the engaging process of automatic clutch is studied from the vehicle normal start and big initial slope start. Based on analyzing the control strategy, the test is carried out with dSPACE rapid control prototype tool. The results show that the control strategy of automatic clutch can not only guarantee the rapid state- switching, but also meet the special requirements of big initial slope start.
