摘要:
A vehicle door control apparatus is provided with an authentication unit, a detection unit and a control unit. The authentication unit authenticates an ID information outputted from a mobile device carried by a user. The detection unit detects an object around a door. The control unit performs an opening operation of the door at least when both a first condition and a second condition are satisfied. In the first condition, the authentication unit authenticates the ID information. In the second condition, the detection unit detects that the object is separated from a predetermined determination area after the object is continuously located in the determination area over a predetermined time.
