PARKING SUPPORT DEVICE AND PARKING SUPPORT METHOD

A parking support device includes: an acquisition circuit configured to acquire first detection points related to obstacles around a vehicle before setting a parking direction, and acquire second detection points related to the obstacles after setting the parking direction; an analysis circuit configured to calculate first approximate straight lines and first variations for first detection point groups related to the first detection points, and calculate second approximate straight lines and second variations for second detection point groups related to the second detection points; a setting circuit configured to set a parking point based on the first detection points, and set the parking direction based on the first approximate straight lines and the first variations; and a correction circuit configured to correct the parking direction using a correction amount calculated using the second approximate straight lines weighted based on the second variations after setting the parking direction.
