摘要：
A method and system of deriving a travel distance of an object which travels, comprising the steps of:
measuring a forward travel velocity of the object under forward travel;
discriminating whether or not the measured forward travel velocity is greater than a preset specified velocity;
detecting a level of a backward travel signal indicative of a state of the object under backward travel, when the measured forward travel velocity is greater than the specified velocity; and
calculating the travel distance of the object independently of the travel distance of the object in a case that a level of the backward travel signal differs from the detected level.
