Collision preventing device for vehicle

#1. Field of the Invention

#The present invention relates to a collision preventing device for a vehicle, and, more particularly, to means for warning a driver by exerted force.

#2. Description of the Related Art

#FIG. 1 is a diagram showing a first example of obstacle detection ranges and the locations of obstacle detecting sensors of a vehicle collision preventing device of the present invention;

#FIG. 2 is a diagram showing a second example of obstacle detection ranges and the locations of obstacle detecting sensors of the vehicle collision preventing device of the present invention;

#FIG. 3 is a diagram showing a third example of an obstacle detection range and the location of an obstacle detecting sensor of the vehicle collision preventing device of the present invention;

#A description of locations of obstacle detecting sensors of a vehicle collision preventing device of the present invention and ranges of detection of an obstacle by the obstacle detecting sensors are given with reference to FIGS. 1 and 2. The location of an obstacle detecting sensor of the vehicle collision preventing device of the present invention and a range of detection of the obstacle by the obstacle detecting sensor is given with reference to FIG. 3. In these figures, reference numeral 1 denotes a vehicle body, reference numeral or numerals 2 denote obstacle detecting sensors, reference numeral or numerals 3 denote obstacle detection ranges of the obstacle detecting sensors 2, reference numerals 4 denote side mirrors, and reference character A denotes an obstacle.

#FIG. 1 illustrates an example in which a total of four obstacle detecting sensors 2 is disposed at the right front corner, the left front corner, the right rear corner, and the left rear corner of the vehicle body 1, respectively. As is clear from FIG. 1, in this example, since the obstacle detecting sensors 2 can monitor substantially the whole area surrounding the vehicle body 1, the obstacle A can be detected in any area surrounding the vehicle body 1. Therefore, a collision preventing device which is optimally effective in preventing collision can be constructed.

#FIG. 2 illustrates an example in which a total of only two obstacle detecting sensors 2 is disposed at the right front corner and the left front corner of the vehicle body 1. As is clear from FIG. 2, in the example, although the obstacle detection ranges 3 of the obstacle detecting sensors 2 are limited to areas surrounding the right front corner and the left front corner, since fewer obstacle detecting sensors 2 are used, it is possible to provide a lower-cost collision preventing device.
