Abstract:
A method of sensing wheel rotation can include: sensing magnetic force information in an environment of a wheel by a magnetometer to obtain measured magnetic force information; generating relative magnetic force information by performing mathematical operation processing in accordance with the measured magnetic force information, where the relative magnetic force information does not change with geomagnetic field and does change with a rotation angle of a wheel; and obtaining angle information related to the rotation angle of the wheel in accordance with the relative magnetic force information.
