And S4, determining the offset amount and the offset direction of the power door moving end 10 according to the offset amount and the offset direction of the magnetic field detection points 60. If the magnetic field detection point 60 generating the induction signal is deviated to the left, it means that the moving end 10 of the electric door is deviated to the right; if the magnetic field detecting point 60 generating the induction signal is shifted to the right, it means that the power door moving end 10 is shifted to the left.

Alternatively, after determining the offset and the offset direction of the power door moving end 10, the power door moving end 10 adjusts the heading according to the offset and the offset direction, so that the power door moving end 10 is adjusted to the correct heading.
In this embodiment, not only the current position of the power door moving end 10 can be determined by the number of the magnetic field detecting points 60, but also the offset amount and the offset direction of the power door moving end 10 can be determined,
