为了避免车辆传动系中齿隙引起的不必要的振动和噪音，对齿隙大小的准确和最新估计是至关重要的。在这项工作中，我们开发了一种实用的基于卡尔曼滤波的汽车传动系间隙大小估计器。开发的估计器不需要任何额外的传感器，并使用车辆CAN总线上的可用速度测量。我们使用实验收集的车辆测试数据验证了这个间隙大小估计器，并观察到估计的间隙大小在实际传动系间隙大小的98%以内。最后，利用一个仿真模型，分析了该估计器对执行机构扭矩轨迹变化的鲁棒性，并观察到对间隙大小估计的准确率超过99%。
To avoid undesirable vibration and noise caused by backlash in a vehicle driveline, it is essential that an accurate and up-to-date estimate of the backlash size be available. In this work, we develop a practical Kalman filter-based backlash size estimator for automotive drivelines. The developed estimator does not require any additional sensors, and uses available speed measurements from the vehicle CAN bus. We validate this backlash size estimator using experimentally collected vehicle test data, and observe that the backlash size estimates are within 98% of the actual driveline's backlash size. Finally, using a simulation model, we analyze the robustness of the estimator to variations in the trajectories of the actuator torque, and observe an accuracy of more than 99% in the backlash size estimate.
