The invention provides a slip detection method and device and a vehicle, and the method comprises the steps: obtaining a first sound signal between a wheel of the vehicle and a wheel track when the vehicle runs on the wheel track; acquiring an acoustic characteristic value of the first sound signal; and under the condition of determining that the acoustic characteristic value of the first sound signal is within the reference range, determining that the vehicle slips. Whether the vehicle slips or not is judged based on the acoustic characteristic value of the sound signal generated by the slipping howling, the slipping phenomenon of the vehicle in the rail transit can be effectively recognized, anti-slipping treatment can be carried out in time, and the key point of research of technicians in the field is achieved.
本申请提供一种打滑检测方法、装置及车辆,所述方法包括:当车辆在轮轨上运行时,获取车辆的车轮与轮轨之间的第一声音信号;获取该第一声音信号的声学特征值;在确定该第一声音信号的声学特征值在参考范围内的情况下,确定车辆发生打滑现象。基于打滑啸叫产生的声音信号的声学特征值判断车辆是否打滑,可以有效识别轨道交通中车辆的打滑现象,以便及时作出防滑处理,成为了本领域技术人员研究的重点。
