Abstract

A parking assist system includes an electronic control unit. The electronic control unit is configured to detect an obstacle, detect a boundary of a parking space, determine a target position to which a vehicle moves, and, when the vehicle is allowed to be located in a third area in which a first area and a second area overlap with each other, be allowed to determine the target position in the third area. The first area is an area across a limit line from the obstacle. The limit line is set substantially along an outer periphery of the obstacle at a position spaced a predetermined distance from the obstacle outward of the obstacle. The second area is an area out of the boundary.

Claims

1. A parking assist system comprising:

an electronic control unit configured to

detect an obstacle,

detect a boundary of a parking space,

determine a target position to which a vehicle moves, and

when the vehicle is allowed to be located in a third area in which a first area and a second area overlap with each other, be allowed to determine the target position in the third area, the first area being an area across a limit line from the obstacle, the limit line being set substantially along an outer periphery of the obstacle at a position spaced a predetermined distance from the obstacle outward of the obstacle, the second area being an area out of the boundary.

2. The parking assist system according to claim 1, wherein

the electronic control unit is configured to set an orientation of the vehicle at the target position on a basis of the boundary.

3. The parking assist system according to claim 1, wherein

the electronic control unit is configured to be able to update the target position on a basis of at least one of the detected obstacle or the detected boundary in a middle of movement of the vehicle to the target position.

4. The parking assist system according to claim 2, wherein

the electronic control unit is configured to be able to update the target position on a basis of at least one of the detected obstacle or the detected boundary in a middle of movement of the vehicle to the target position.
