Abstract: A seat load detection method includes a process in which a control unit records a transition of a load detection signal and a transition of a seat load, a process in which the control unit specifies a timing when a load sensor detects a collision of a vehicle based on a transition record of the load detection signal, and a process in which the control unit calculates a correction value of the seat load based on a difference value between a stable seat load provided after the control unit detects the collision of the vehicle and a stable seat load provided before the load sensor detects the collision of the vehicle.
