摘　　要：研究了换档质量对车辆各部分性能的影响,给出了相应的评价指标。基于支持向量机的理论和技术,构建了换档质量评价系统。同时结合试验对装载自动机械式变速器的车辆进行分析,提出了新的、更加完整的换档质量评价概念,从而扩宽了传统换档质量评价的研究范围。试验分析表明,所建立的换档评价系统与传统评价方法相比,能够更加全面地表征换档质量对车辆性能的影响。Effect of shift quality on performances of vehicle components was studied and the corresponding evaluation indexes were provided. Based on the theory and technique of the support vector machines （SVMs）, an assessment system was built. A new and complete concept of shift quality was developed based on the gear shift test of a car equipped with an automated manual transmission （AMT）. The test results show that in comparison with the traditional assessment system, the proposed vehicle gear shift quality assessment system can more completely characterize the effect of the gear shift quality on vehicle performance.
