The invention provides a road adhesion coefficient calculation method, device and system, and the method comprises the steps: carrying out the conversion processing of a vehicle body driving signal collected in advance, and obtaining the initial vehicle data of a target vehicle; determining a slip angle, a vertical force and a lateral force of a target tire of the target vehicle according to the initial vehicle data; and inputting the vertical force, the lateral force and the slip angle into a preset time delay neural network model, and outputting a road adhesion coefficient. Only the existing sensor on the vehicle needs to be utilized in the data acquisition process, so that the data acquisition cost is reduced; the road adhesion coefficient is calculated and predicted through the offline trained time delay neural network model, and the calculation and prediction efficiency and accuracy are improved.

    本发明提供了一种路面附着系数的计算方法、装置和系统,该方法包括:对预先采集的车身行驶信号进行转换处理,得到目标车辆的初始车辆数据;根据初始车辆数据,确定目标车辆的目标轮胎的侧偏角、垂向力和侧向力;将垂向力、侧向力和侧偏角输入至预设的时延神经网络模型中,输出路面附着系数。本发明的数据采集过程只需利用车辆上现有的传感器,降低了数据采集的成本;通过离线训练的时延神经网络模型对路面附着系数进行计算与预测,提高了计算、预测的效率和准确率。
