Title:
PATH GENERATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/105400
Kind Code:
A1
Abstract:
A path generation unit (35) is capable of generating an autonomous travel path whereupon autonomous travel is carried out by a travel body (automobile unit). An acquisition unit (57) acquires a retained quantity of fuel which the travel body retains. An assessment unit (58) assesses whether it is possible to complete the autonomous travel in the autonomous travel path by the retained quantity of fuel. A resupply position setting unit (56) sets a fuel resupply position (resupply position) of the fuel. The path generation unit (35) is capable of generating a fuel resupply path from a fuel resupply commencement position upon the autonomous travel path to the fuel resupply position if it is assessed by the assessment unit (58) that it is not possible to complete the autonomous travel. On the basis of the retained quantity of fuel, the path generation unit (35) sets the fuel resupply commencement position such that it will be possible to complete the autonomous travel to the fuel resupply commencement position and the autonomous travel in a fuel resupply path from the fuel resupply commencement position to the fuel resupply position.
