The invention relates to the technical field of tires, in particular to an indirect tire pressure monitoring method and device, a vehicle and a storage medium, and the method comprises the following steps: obtaining training data carrying a normal tire pressure label and an underpressure label; performing signal processing on a wheel speed signal in the training data to obtain a processed wheel speed signal, and performing detrending processing on the processed wheel speed signal to obtain a wheel speed microscopic signal; and extracting wheel speed microscopic vibration characteristics in the wheel speed microscopic signal, training a pre-constructed neural network by using the wheel speed microscopic vibration characteristics, obtaining a tire pressure probability identification model after training is finished, and identifying the pressure state of each tire in the vehicle by using the tire pressure probability identification model. Therefore, the problems that in the prior art, a tire rigid ring model needs to be constructed manually, the generalization ability for uncalibrated tires does not exist, and the cost input is high are solved.
本申请涉及轮胎技术领域,特别涉及一种间接式轮胎压力监测方法、装置、车辆及存储介质,其中,方法包括:获取携带有正常胎压标签和欠压标签的训练数据;对训练数据中的轮速信号进行信号处理,得到处理后的轮速信号,对处理后的轮速信号进行去趋势化处理得到轮速微观信号;提取轮速微观信号中的轮速微观振动特征,利用轮速微观振动特征训练预先构建的神经网络,在训练结束后得到轮胎气压概率辨识模型,利用轮胎气压概率辨识模型识别车辆中每个轮胎的压力状态。由此,解决了相关技术中需要人为构建轮胎刚性环模型,不具备针对未标定过轮胎的泛化能力,成本投入高等问题。
