초록 ▼

A vehicle guidance system for assisting a driving lane change includes an object detection unit for detecting objects in a laterally adjacent rearward side space area of the vehicle. An analysis unit receives signals from the object detection unit and determines whether an object is situated in a dead angle section (blind spot) of the monitored rearward side space, or whether any such object in a section of the monitored rearward side space which is rearward beyond a dead angle section is moving forward at a higher speed than the system vehicle. If so, and if, in addition, it detects at the same time a lane change request pertaining to the corresponding side area, it activates a warning indicating unit for emitting a warning signal. According to the invention, a position detection device is provided which determines path data of the obstacle vehicle and the road geometry data, as well as the position of the system vehicle on the road. When the object detection unit detects an obstacle vehicle which is following in the rearward side space, corresponding to the covered distance recorded by the position detection device and the road geometry, a position assignment of the vehicle which is following is determined relative to the road.

1. A guidance system for assisting a driving lane change of a vehicle, comprising:an object detection unit for detecting objects in a monitored area which is rearward and laterally adjacent of the vehicle; a warning indicating unit; an analysis unit which determines by means of signals supplied to it by the object detection unit whether an object is situated in a dead angle section of the monitored rearward area, and whether an object in a section of the monitored rearward side space which is rearwardly beyond the dead angle section is moving forward at a higher speed than the vehicle, and activates the warning indicating unit for emitting a warning signal if, in addition, it detects a lane change request pertaining to the corresponding side area; wherein a position detection device determines path data for the vehicle and road geometry data for a road on which the vehicle travels, as well as a position of the vehicle on the road; an analysis unit stores said path data, road geometry, and position of the vehicle; and when the object detection unit detects an object which is following in the rearward side space, corresponding to a road distance traveled by the vehicle, for which the position detection device has determined path data and road geometry that are stored by said analysis unit, a position assignment of the object relative to the road is determined by the analysis unit relative to the road, based on the stored path data and road geometry.
