Title: Working machine controller for hydraulic shovel
Inventor: HIGUCHI FUMIKAZU
IPC: E02F9/24
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To smoothly and automatically enable a working machine to avoid a danger by setting larger the distance between the boundary face of an automatic avoidance zone set ahead of a cab and the cab as it is far from a zone which the working machine reaches after transfer and making the working machine transfer alone the boundary face of the automatic avoidance zone when it has reached the zone. SOLUTION: When a working machine 14 has reached an automatic avoidance zone K set ahead of a cab, it is forced to transfer along the boundary face N of the automatic avoidance zone K. The distance from the boundary face N of the automatic avoidance zone to the cab 11 is set larger as it is far from a zone which the working machine 14 reaches after transfer. That is, the forward distance L1 of the forward left side of the cab 11 far from the safe zone which the machine reaches after avoidance is set larger than the distance S1 of the forward right side of the cab 11. In this way, as the working machine 14 is located in a position where a time is required to reach the area, since it starts an offset transfer from a position separated from the cab 14 as shown in the arrow mark A, the movement becomes smooth and the automatic avoidance time can be reduced.
