Abstract
A safe remote-control door opening-and-closing device for an automotive vehicle by which the door can not be opened or the door now being opened is closed, even if the driver operates the door open switch, in the case where there exists an obstruction within a predetermined warning region near the vehicle door or around the vehicle. The safe remote-control door device according to the present invention comprises an obstruction sensor for detecting the presence of an obstruction, if any, and a switching unit for disconnecting the door open switch from the door driving device or for connecting the door open switch to the reverse revolution terminal of the driving device in order to close the door now being opened, in addition to a conventional remote-control door opening-and-closing device.
