Radarvorrichtung eines Kraftfahrzeugs zum Erzeugen eines genauen Strahlachsenkorrekturwertes

摘要

A radar apparatus of an automotive vehicle includes a radar unit which outputs signals at intervals of a predetermined time, each signal indicating data of a position of a target at an output time. A position detecting unit detects data of the position of the target from the signals output by the radar unit when the vehicle operates in a straight line path. A correction value determining unit generates a set of errors of a beam emission axis to the straight line path with respect to a horizontal direction so that an average of the errors with respect to each of the signals is determined from the data detected by the position detecting unit. The correction value determining unit determines a correction value by taking an average of the averages of the errors with respect to all the signals.
