The invention discloses a wheel speed estimation method and device and a vehicle. The method comprises the following steps: firstly, acquiring a wheel speed square wave signal, then recording the timelabel of the last rising edge and/or falling edge within the ith preset interval time, then recording the number of detected rising edges and/or falling edges within the jth preset interval time, andmarking the time label on the rising edges and/or falling edges, calculating a first estimation period within the j-th preset interval time according to the time labels of the two times and the number of the rising edges and/or the falling edges, and calculating the wheel speed within the j-th preset interval time according to the first estimation period, where i and j are both positive integers,i

    本发明公开了一种轮速估算方法、装置和车辆。其中,该方法包括,首先获取轮速方波信号,接着记录在第i预设间隔时间内的最后一个上升沿和/或下降沿的时间标签,接着在第j预设间隔时间内,记录检测到上升沿和/或下降沿的个数,并为其打上时间标签,根据前述两次的时间标签以及上升沿和/或下降沿的个数计算在j预设间隔时间内的第一估算周期,根据第一估算周期计算所述第j预设间隔时间内的轮速,其中,i,j均为正整数;i
