The invention provides a tire longitudinal speed estimation method, device, system and equipment. The method comprises the following steps: determining key feature points of a strain response signal in a grounding print area according to tread strain information; inputting the key feature points into a preset tire longitudinal speed prediction model to obtain a first tire longitudinal speed; determining the longitudinal slip rate of the tire according to the tread strain information and a preset slip rate prediction model; calculating a second tire longitudinal speed of the tire according to the longitudinal slip rate; and carrying out weighted fusion on the first tire longitudinal speed and the second tire longitudinal speed to obtain the tire longitudinal speed. According to the method, the first tire longitudinal speed is obtained directly through the key feature points of the strain response signals in the grounding print area; indirectly calculating a second tire longitudinal speed of the tire through the longitudinal slip rate of the tire; and finally, carrying out weighted fusion on the first tire longitudinal speed and the second tire longitudinal speed so as to accurately estimate the tire longitudinal speed through two different modes.

    本申请提出了一种轮胎纵向速度估计方法、装置、系统及设备,该方法根据胎面应变信息确定接地印迹区域内应变响应信号的关键特征点;将关键特征点输入至预设轮胎纵向速度预测模型,得到第一轮胎纵向速度;根据胎面应变信息以及预设滑移率预测模型确定轮胎的纵向滑移率;根据纵向滑移率计算轮胎的第二轮胎纵向速度;将第一轮胎纵向速度与第二轮胎纵向速度进行加权融合得到轮胎纵向速度。本申请直接通过接地印迹区域内应变响应信号的关键特征点得到第一轮胎纵向速度;间接通过轮胎的纵向滑移率计算轮胎的第二轮胎纵向速度;最后将第一轮胎纵向速度与第二轮胎纵向速度加权融合,从而通过两种不同的方式对轮胎纵向速度进行准确估计。
