Device for detecting a danger of collision between two objects, in particular vehicles, in motion relative to each other

摘要

A transmitter on each object transmits an optical beam in the infrared or visible range, in all directions. A receiver is arranged on each object, comprising at least two planar receivers for each quadrant of the coordinate system of the object, the receivers being at an angle to each other. A controller activates the receiver at intervals. A signal processor calculates the distance of the objects and the position angle of the objects and generates a collision signal if the position angle is constant and the spacing of the objects is decreasing.
