Parking assistance method, parking assistance apparatus, and non-transitory computer readable recording medium

An apparatus for assisting parking of a vehicle in a parking lot, the apparatus configured to execute:

• generating node information from a start position to an end position of a leaving operation of the vehicle when a leaving of the vehicle is started;
• calculating a reference distance which is a distance between a start node being a node corresponding to the start position and a reference node being a node located in front of the vehicle among nodes located on a drive aisle of the parking lot;
• calculating, for respective target nodes, an aisle distance which is a distance from the reference node, the target nodes being nodes from the reference node to an end node being a node corresponding to the end position;
• identifying a specific node which is a node whose the aisle distance is most approximate to the reference distance among the target nodes;
• and
• transmitting, to the vehicle, the node information regarding the start node and regarding the target nodes from the specific node to the end node.

A non-transitory computer readable recording medium on which a computer program for assisting parking of a vehicle in a parking lot is recorded,

• the computer program, when executed by a computer, causing the computer to execute:
• generating node information from a start position to an end position of a leaving operation of the vehicle when a leaving of the vehicle is started;
• calculating a reference distance which is a distance between a start node being a node corresponding to the start position and a reference node being a node located in front of the vehicle among nodes located on a drive aisle of the parking lot;
• calculating, for respective target nodes, an aisle distance which is a distance from the reference node, the target nodes being nodes from the reference node to an end node being a node corresponding to the end position;
• identifying a specific node which is a node whose the aisle distance is most approximate to the reference distance among the target nodes;
• and
• transmitting, to the vehicle, the node information regarding the start node and regarding the target nodes from the specific node to the end node.
