Ship collision accident negligence ratio calculation device

摘要

To provide a collision avoidance behavior and a weather condition on the basis of a basic score determined for each collision situation, and to calculate a score by adding / subtracting scores on the basis of a basic score determined for each collision situation Then, calculate. However, with simple addition / subtraction, the reversal phenomenon occurred in which the fault rate of B became large despite A as a main cause of negligence.SOLUTION: From the past accident case or the like, the maximum value Hmax of the scores of A to be permitted, or the minimum value Hmin of the score of B which is permitted is obtained within a range where reversal does not occur. Then, in order to avoid exceeding these values, the maximum error rate variation range H, which is the maximum fluctuation width that is permitted, is obtained by an actual collision accident. Further, what percentage of this H is applied to an actual collision accident depends on the ratio of the actual score to the maximum value that the score of the collision avoidance action can take, and the maximum It depends on the ratio of the actual score to the value.(FIG.
