<p>PURPOSE:To recognize a reflector set where a road is curved distinctively from a stopping vehicle and to hold outputting of an alarm when an interrupting vehicle runs faster than one's own vehicle. CONSTITUTION:The distances to obstacles at the center, left and right in front of a vehicle are measured by distance sensors 11-13, and the vehicle speed is measured by a vehicle speed sensor 17. The characteristic amount of the distance data and speed data (average difference, minimum difference, minimum value, inverted number of code etc.), is operated in an operating part 20. A fuzzy inference is carried out when the obtained characteristic amount is input to a fuzzy inference part 21, thereby detecting the necessity of an alarm.</p> |
