Abstract
A lost article prevention device includes a sensor, a communication device, and a controller. The sensor is configured to detect a state inside a vehicle cabin. The communication device is configured to receive alighting point information being information of an alighting point of a passenger. The controller is configured to determine whether or not a vehicle has arrived at the alighting point on a basis of the alighting point information, and determine whether or not a lost article of the passenger is present in the vehicle cabin on a basis of a detection result of the sensor. The controller releases a closed state of a door when the vehicle is determined to have arrived at the alighting point and the lost article is determined not to be present, and maintains the closed state of the door when the vehicle is determined to have arrived at the alighting point and the lost article is determined to be present.
