Abstract:
A dozing system for use in a bulldozer, the system comprising:(a) cutting edge position detecting means for detecting the position of the cutting edge of a blade in relation to the ground;(b) target cutting edge position setting means for setting a target position of the cutting edge of the blade in relation to the ground;(c) load condition detecting means for determining whether the load exerted on the blade is in a stable state;(d) target cutting edge position correcting means for correcting the target cutting edge position set by the target cutting edge position setting means to the actual position of the cutting edge at that time, if the load condition detecting means determines that the load exerted on the blade is in a stable state when dozing operation is performed in an automatic digging mode; and(e) blade controlling means for controlling the blade to be lifted or lowered such that the position of the cutting edge of the blade detected by the cutting edge position detecting means is made coincident with the target cutting edge position corrected by the target cutting edge position correcting means.
