| 中文摘要: |
| 某混动汽车在D挡怠速充电工况下，主观驾评存在严重的轰鸣，采集数据并进行滤波分析，发现37 Hz峰值是导致车内轰鸣的主要原因，并超过车内的怠速目标。在详细了解该车型传动系结构的基础上，通过分析整车传递路径，找到了半轴-转向节这条路径为主要传递路径。D挡怠速充电工况下驱动电机施加扭矩，传动系间隙消除且预紧，发动机激励通过半轴传递到转向节，激励起轮胎悬挂系统35 Hz的扭转模态，引起车内怠速轰鸣。将驱动电机扭矩从2 Nm调整到1.4 Nm后，车内轰鸣主观感觉基本可接受，客观目标也基本达成。 |
| 英文摘要: |
| A hybrid car has serious subjective booming in the D-gear idle charging condition. According to the target, and noise filtering and replaying, it is determined that the peak of 37 Hz is the main cause of booming. On the basis of a detailed understanding of the driveline structure, and based on the analysis of transfer path, the main path was found to be from the half axle to the steering knuckle. Under the D-gear idle charging condition, when the driving motor applies torque, the clearance between the driveline system is eliminated and tightened, and the engine excitation is transmitted to the steering knuckle through the half shaft, activating the 35 Hz torsional mode of the tire suspension system and causing idle booming inside the car. After adjusting the torque of the drive motor from 2 Nm to 1.4 Nm, the subjective feeling of the car's booming is basically acceptable, and the objective goal is also basically achieved. |
