The invention discloses a road surface type identification method and device, a storage medium and a vehicle. The method comprises the steps that the suspension vertical displacement of the vehicle and the sprung vertical acceleration of the vehicle are obtained; judging whether the vehicle runs on a bumpy road surface or not according to the suspension vertical displacement of the vehicle and the sprung vertical acceleration of the vehicle; when the vehicle runs on a bumpy road surface, preset vehicle motion parameters related to vehicle bumpy information are obtained; the preset vehicle motion parameters serve as input quantities and are sent to a preset model used for calculating the jolting type; and obtaining a bumping type prediction result output by the preset model. By adopting the scheme provided by the invention, whether the vehicle runs on the bumpy road surface or not is comprehensively judged through the suspension vertical displacement of the vehicle and the sprung vertical acceleration of the vehicle, the interference of conditions such as rapid acceleration and rapid deceleration on the road surface type identification process is eliminated, the probability of wrong identification of the road surface type is reduced, and the identification accuracy is improved. And the accuracy of road surface recognition is improved.
本申请公开了一种路面类型识别方法、装置、存储介质及车辆,所述方法包括:获取车辆的悬架垂向位移和车辆的簧下垂向加速度;根据车辆的悬架垂向位移和车辆的簧下垂向加速度判断所述车辆是否行驶于颠簸路面;当所述车辆行驶于颠簸路面时,获取与车辆颠簸信息相关的预设车辆运动参数;将预设车辆运动参数作为输入量发送给用于计算颠簸类型的预设模型;获取预设模型输出的颠簸类型的预测结果。采用本申请所提供的方案,通过车辆的悬架垂向位移和车辆的簧下垂向加速度二者综合判断车辆是否行驶于颠簸路面,排除了急加速和急减速等情况对于路面类型识别过程中的干扰,降低了路面类型误识别的概率,提升了路面识别的准确性。
