Abstract

A drop-off assist device includes: a processor configured to determine that there is a possibility that a target approaching object passes by a door of a host vehicle when a second object is not present between the target approaching object and the host vehicle, correct the predicted movement path based on a position of an edge of the second object when the second object is present between the target approaching object and the host vehicle at a timing of setting the target approaching object, determine that there is the possibility that the target approaching object passes by the door of the host vehicle when the corrected predicted movement path is the path that passes by the door of the host vehicle, and issue an alarm when determining that there is the possibility that the target approaching object passes by the door of the host vehicle.

First claim

What is claimed is:

1. A drop-off assist device comprising:
a radio wave sensor configured to detect an object; and
a processor configured to
detect an object that is approaching a host vehicle based on results of detection by the radio wave sensor,
acquire a predicted movement path of the object based on the results of the detection by the radio wave sensor when the object is detected,
set the object as a target approaching object when the predicted movement path acquired by the processor is a path that passes by a door of the host vehicle,
determine that there is a possibility that the target approaching object passes by the door of the host vehicle when a second object that is different from the target approaching object is not present between the target approaching object and the host vehicle,
correct the predicted movement path based on a position of an edge of the second object when the second object is present between the target approaching object and the host vehicle at a timing of setting the target approaching object,
determine that there is the possibility that the target approaching object passes by the door of the host vehicle when the predicted movement path corrected by the processor is the path that passes by the door of the host vehicle, and
issue an alarm when determining that there is the possibility that the target approaching object passes by the door of the host vehicle.

2. The drop-off assist device according to claim 1 , wherein the processor is configured to:
determine that the predicted movement path acquired by the processor is the path that passes by the door of the host vehicle when the predicted movement path acquired by the processor is a path that passes through an area within a predetermined distance in a vehicle transverse direction from the host vehicle; and
determine that the predicted movement path corrected by the processor is the path that passes by the door of the host vehicle when the predicted movement path corrected by the processor is the path that passes through the area within the predetermined distance in the vehicle transverse direction.

3. The drop-off assist device according to claim 1 , wherein the processor is configured to set the object as the target approaching object when the predicted movement path acquired by the processor is the path that passes by the door of the host vehicle at a time when a time predicted to be taken before the object reaches a location by the door of the host vehicle becomes equal to or less than a predetermined time.
