The invention provides a wheel rotation detection device, a vehicle and a wheel rotation detection method. The wheel rotation detection device comprises a first unipolar Hall sensor used for sensing a magnetic field of a first polarity, a second unipolar Hall sensor used for sensing a magnetic field of a second polarity, a first magnet used for generating the first magnetic field of the first polarity, a second magnet used for generating the second magnetic field of the second polarity, a processor and a brake disc rotating along with the wheels, wherein the magnets are fixed on the brake disc; due to the arrangement positions of the first unipolar Hall sensor and the second unipolar Hall sensor, in the process that the brake disc drives the first magnet and the second magnet to rotate, a state of the first unipolar Hall sensor relative to a first magnetic field is changed, and a state of the second unipolar Hall sensor relative to a second magnetic field is changed; the processor is set to determine whether the wheels rotate or not according to the first induction signals and the second induction signals outputted by the two unipolar Hall sensors.
本公开提供了车轮转动检测装置、车辆及车轮转动检测方法,车轮转动检测装置包括用于感应第一极性的磁场的第一个单极性霍尔传感器、用于感应第二极性的磁场的第二个单极性霍尔传感器、用于产生第一极性的第一磁场的第一磁铁、用于产生第二极性的第二磁场的第二磁铁、处理器和随着车轮转动的闸盘,磁铁均固定在闸盘上;第一个单极性霍尔传感器和第二个单极性霍尔传感器的设置位置,使得闸盘带动第一磁铁和第二磁铁转动的过程中,第一个单极性霍尔传感器相对于第一磁场的状态发生改变,第二个单极性霍尔传感器相对于第二磁场的状态发生改变;处理器被设置为根据两个单极性霍尔传感器输出的第一感应信号和第二感应信号,确定车轮是否发生转动。
