Seat limit position calibration method based on current integration window

The invention discloses a seat limit position calibration method based on a current integration window. The method comprises the following steps that: a motor drives a seat to move forwards along a guide rail at a fixed speed V; a motor bus current value is monitored through a bus current sensor of the motor; whether the seat reaches a forward limit position on the guide rail or not is judged through a motor bus current value integration window mode, and the forward limit position is recorded when the seat reaches the forward limit position; after the seat reaches the forward limit position, the motor drives the seat to be started backwards, and when the seat reaches a set speed, the seat is switched to the fixed speed V to control the seat to move backwards; and when the seat moves backwards at the fixed speed V, whether the seat reaches the backward limit position or not is judged in a motor bus current value integration window mode, and the backward limit position is recorded when the seat reaches the back
