SELF POSITION ESTIMATION METHOD AND SELF POSITION ESTIMATION DEVICE

A self position estimation method is provided which is capable of accurately estimating, when executing automatic parking to a parking target position using a stored surrounding situation, a position of a host vehicle or a target in the surrounding situation stored in a storage device (2). The method includes a step (S24) that presents the stored surrounding situation, a step (S25) that receives an operation of set ting a positional relationship between the stored surrounding situation, and at least one of the host vehicle and the targets existing around the host vehicle, and a step (S26) that sets a position of at least one of the host vehicle and the target in the stored surrounding situation based on the operation.
