Abstract

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.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and more specifically, the present invention relates to a wheel rotation detection device, a vehicle, and a wheel rotation detection method for a vehicle. Background technique [0002] At present, travel through shared vehicles has become an emerging travel mode in cities, which can effectively solve the travel needs of urban people and is green and environmentally friendly. In order to regulate the user's parking, usually a parking area is set in the map to guide the user to park the used vehicle in the parking area. [0003] During the use of the shared vehicle, the user can send a lock instruction to the shared vehicle through the mobile terminal of the shared vehicle. When the shared vehicle receives the lock command, it executes the lock action. [0004] If the shared vehicle performs the locking action in a non-stationary state, it may cause harm to the personal safety of users ...
