Alighting support device
An alighting support device performs warning to notify a vehicle occupant of presence of a moving body having a possibility to come into contact with a right door or a left door of the vehicle. The alighting support device performs the warning when a warning condition is satisfied. When the right door or the left door is opened or is about to be opened while the moving body is moving in a right warning area set on the right side of the vehicle or a left warning area set on the left side of the vehicle, the alighting support device determines that the warning condition is satisfied. When the moving body enters the right warning area or the left warning area with the right door or the left door being open to a predetermined degree or more, the alighting support device determines that the warning condition is not satisfied.
