Abstract
PURPOSE:To enable the issuance of an alarm even when an obstacle comes into a dead angle of the range of detection, by adding a dead-angle detection circuit and an alarm circuit to an obstacle detection device. CONSTITUTION:When an obstacle approaches an automobile and comes into the dead angle of the range of detection, the output of a distance discrimination circuit 5 is discontinued, and a distance discrimination circuit 8 also delivers no output at this time. Therefore, a dead-angle detection circuit 30 delivers an output to make an alarm circuit 31 deliver a special alarm continuously for a prescribed time. This constitution makes it possible to inform a driver that the obstacle comes very near to the automobile and to call his attention thereto.
