The invention discloses a tire slippage determination method and device and a nonvolatile storage medium. The method comprises the steps that contact parameters corresponding to each node in a plurality of nodes in a three-dimensional model are obtained, the three-dimensional model comprises a tire and a rim in a vehicle, the nodes are contact points in a contact area of the tire and the rim, and the contact parameters at least comprise contact pressure, contact area and radial coordinates; determining friction torque between the tire and the rim according to the contact parameters; determining a driving torque transmitted to the tires by an engine of the vehicle; and comparing the friction torque with the driving torque, and determining whether slippage occurs between the tire and the rim or not according to a comparison result. According to the method and the device, the technical problems of relatively low efficiency and relatively high cost of determining the friction torque between the tire and the rim due to the fact that the friction torque between the tire and the rim cannot be determined in a modeling manner in related technologies are solved.
本申请公开了一种轮胎滑移的确定方法及装置、非易失性存储介质。其中,该方法包括:获取三维模型中多个节点中的每个节点对应的接触参数,其中,三维模型中包括:车辆中的轮胎和轮辋,节点为轮胎与轮辋的接触区域中的接触点,接触参数至少包括:接触压力、接触面积以及径向坐标;根据接触参数,确定轮胎与轮辋之间的摩擦力矩;确定车辆的发动机传递到轮胎上的驱动力矩;将摩擦力矩与驱动力矩进行比较,并根据比较结果,确定轮胎与轮辋之间是否发生滑移。本申请解决了由于相关技术无法通过建模方式确定轮胎与轮辋之间的摩擦力矩,造成的确定轮胎与轮辋之间的摩擦力矩的效率较低且成本较高的技术问题。
