ABSTRACT:
A dozing system for use in a bulldozer, having the capability of estimating a loading ratio (the ratio of soil loaded on the blade to the loading capacity of the blade) with high accuracy so that a mode shift from digging to carrying can be stably performed. Data pieces each representing the digging distance of the bulldozer and the associated loading ratio are obtained from n previous dozing operations and stored. The average of the stored data pieces obtained from n operations is calculated and according to the average, data representative of a digging distance and its associated loading ratio obtained from the present dozing operation is compensated.
