Method and device for outputting a collision warning signal to the surroundings of a medium gauge tram

摘要

The invention relates to a method and a device for outputting a collision warning signal to the surroundings of a central track tram (1) for collision avoidance with regard to a traffic lane (2) of the tram (1) probably crossing left-turning motor vehicle (4), wherein for collision avoidance between tram (1 ) and motor vehicle (4) the following steps are carried out: Determination of a probable left turn intention (A) of a tram (1) on a right parallel lane (5) preceding motor vehicle (4) by a motor vehicle (4) detecting the frontal sensor system Tram (1), and if a left turn intention of the motor vehicle (4) is present, - Making a prognosis (B) about a future risk of collision between tram (1) and motor vehicle (4) taking into account the vehicle spacing and the driving speeds, and if a collision danger likely is, - A Output of a primarily to the preceding motor vehicle (4) directed preventive collision warning signal (C) by the tram (1).
