摘　　要：为了研究制动拖滞力矩对燃油经济性的影响,利用制动系统的密闭性,采取抽真空并保压的方法 ,消除部分卡钳拖滞力矩,并进行整车滑行阻力试验、整车台架制动拖滞力矩分解试验以及等速油耗试验三方面验证。通过本次研究与论证分析,最终得到卡钳拖滞力矩在整车燃油经济性的影响程度。In order to study the influence of Braking Torque on fuel economy, the method of vacuum extraction and pressure preservation is adopted to eliminate part of the braking torque of calipers by using the tightness of braking system, the results are verified by the taxi resistance test, the braking torque decomposition test and the constant speed fuel consumption test. Through this research and demonstration analysis, the contribution of caliper drag torque to the vehicle’s fuel economy is finally obtained.

关 键 词：制动拖滞力矩 滑行阻力 拖滞力矩分解 燃油经济性
