摘要：

车辆安装双质量飞轮(DMF)可改善正常行驶过程中舒适性，但会加剧汽车在熄火过程中传动系统的振动响应。针对该问题，以某型汽车为对象，基于安装双质量飞轮后汽车传动系统的特性，提出了相应的减振控制算法并进行了试验验证。通过不同试验方案及试验结果对比，提出了在汽车熄火时刻，通过ECU控制逻辑关闭进气节流(TVA)阀和废气再循环(EGR)阀，并适当延迟断油时刻的控制算法。该算法使传动系统穿越共振转速区的时间缩短了50%，大幅改善了汽车传动系统的熄火振动。

Abstract:

Vehicle with Dual Mass Flywheel (DMF) reduces the vibration during normal driving conditions at the cost of aggravating the vibration response during the flameout condition. This paper proposes a vibration reduction strategy based on the resonance speed range when the transmission has installed the DMF. This result is concluded by the experiments of a specific type of vehicle. The results of different test schemes indicate that the vehicle in the flameout condition by ECU closes inlet throttling valve (TVA) and exhaust gas recirculation (EGR) valve, and that the control algorithm of cut-off time delay fault oil moment is appropriate. The algorithm saves half of the time of the driveline system through the resonance speed range, thus significantly improving the transmission systems vibration level during the flameout condition.
