Automatic drive control system for a bulldozer
First Claim
1. An automatic drive control system for a bulldozer which is capable of automatically driving a bulldozer such that the bulldozer moves back and forth predetermined times between a digging start position and a digging end position, the automatic drive control system comprising:
- (a) digging start detecting means for detecting that the bulldozer is in the digging start position;
(b) digging end detecting means for detecting that the bulldozer is in the digging end position;
(c) driving direction detecting means for detecting the momentarily varying driving direction of the bulldozer; and
(d) drive controlling means for shifting a transmission into a forward gear when the digging start detecting means detects that the bulldozer is presently in the digging start position;
shifting the transmission into a reverse gear when the digging end detecting means detects that the bulldozer is presently in the digging end position; and
controlling the bulldozer such that the driving direction detected by the driving direction detecting means is made coincident with a target driving direction when the bulldozer is moving from the digging start position towards the digging end position.

Abstract
An automatic drive control system for a bulldozer comprising a digging start detector for detecting that the bulldozer is in a digging start position, a digging end detector for detecting that the bulldozer is in a digging end position, a driving direction detector for detecting the momentarily varying driving direction of the bulldozer, and a drive controller for shifting a transmission into a forward gear when the digging start detector detects that the bulldozer is presently in the digging start position; shifting the transmission into a reverse gear when the digging end detector detects that the bulldozer is presently in the digging end position; and controlling the bulldozer such that the driving direction detected by the driving direction detector is made coincident with a target driving direction when the bulldozer is moving from the digging start position towards the digging end position.
