Abstract
A vehicle surroundings monitoring device in which reflection by a mirror is reduced to ensure the desired performance of distance measurement even in a short-distance range. The monitoring device for monitoring surroundings around a vehicle has a transmitting antenna provided in a door mirror assembly of the vehicle to radiate transmitted waves through a mirror surface of the door mirror, and a receiving antenna provided in the door mirror assembly to receive, through the door mirror surface, reflected waves from an object existing near the vehicle. In the this monitoring device, electric wave transmission surfaces are formed as portions of the door mirror surface corresponding to openings surfaces for the transmitting and receiving antennas to limit reflection by the door mirror surface and to enable transmission of electric waves through the door mirror surface. The electric wave transmission surfaces are formed by partially removing a reflective film formed on the mirror surface, by partially cutting off the mirror surface, or by forming metal slits in portions of the door mirror surface or through the entire door mirror surface.
