Abstract

Abstract This invention relates to a method of controlling an unmanned vehicle (22). When the destination for the vehicle (22) is nominated a control section (10) determines all nodal points (N) to be traversed in reaching the nominated destination and, in addition, establishes, in consecutive sequence, the travel commands for defining the travel direction and speed at each of the nodes (N) to transmit to a travel section (6) controlling the motion of the vehicle (22). The travel section (6) determines the operating pattern and speed pattern appropriate to its own travel function on the basis of the travel commands supplied from the control section (10) so that, in the vehicle (22) travelling on the path and at the speed corresponding to these operating and speed patterns, the control section (10), after having supplied the travel command N referring to the node (N) to be traversed next, will continue to supply to the travel section all further preestablished travel commands N + 1, N + 2, etc. relating to all subsequent nodes (N) to be traversed thereafter. The travel section (6) refers to the travel commands N + 1, N + 2, etc. to correct, in accordance with its own travel functions, the speed pattern determined on the basis of the Nth travel command.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 198 words
A method for controlling an unmanned vehicle (22) having a travel section (6) and a control section (10) which determines the most suitable path traversing a number of nodes (N) to a nominated destination, generates the commands for determining the direction and speed of the vehicle (22) with respect to each consecutive node (N), and conveys these commands to the travel section (6), CHARACTERISED IN THAT the travel section (6) can on the basis of the commands provided by the control section (10) select the rotation and speed patterns of the vehicle (22) and the control section (10) provides in addition to the travel commands relating to the Nth node (N) to be next traversed by the vehicle (22), the commands relating to the N+1th, N+2th, etc nodes (N) to be traversed thereafter by the vehicle (22) and supplies these commands to the travel section (6) whereupon the travel section (6) corrects the speed pattern determined on the basis of the travel command relating to the Nth node (N) by referring to the travel commands relating to the N+1th, N+2th, etc. nodes (N) given by the control section (10) in accordance with the vehicle's (22) own travel functions.
Claim 2
Independent Claim 198 words
A method for controlling an unmanned vehicle (22) having a travel section (6) and a control section (10) which determines the most suitable path traversing a number of nodes (N) to a nominated destination, generates the commands for determining the direction and speed of the vehicle (22) with respect to each consecutive node (N), and conveys these commands to the travel section (6), CHARACTERISED IN THAT the travel section (6) can on the basis of the commands provided by the control section (10) select the rotation and speed patterns of the vehicle (22) and the control section (10) provides in addition to the travel commands relating to the Nth node (N) to be next traversed by the vehicle (22), the commands relating to the N+1th, N+2th, etc nodes (N) to be traversed thereafter by the vehicle (22) and supplies these commands to the travel section (6) whereupon the travel section (6) corrects the speed pattern determined on the basis of the travel command relating to the Nth node (N) by referring to the travel commands relating to the N+1th, N+2th, etc. nodes (N) given by the control section (10) in accordance with the vehicle's (22) own travel functions.
Claim 3
Dependent Claim 18 words
A method according to claim 1 wherein the travel section (6) is equipped with a traverse motion capability.
Claim 4
Dependent Claim 20 words
A method according to claim 1 or 2 wherein the travel section (6) is equipped with an oblique motion capability.
