Title:
AUTONOMOUS DRIVING DEVICE FOR WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/097499
Kind Code:
A1
Abstract:
This autonomous driving device includes: a position estimation unit that has an interaction model and calculates actual position data corresponding to inputted force data as estimated position data; a force computation unit that has a force computation model, computes force data corresponding to an inputted deviation, and inputs the force data to the position estimation unit; a database that stores a base parameter, which is a parameter calculated in the past; and a parameter-setting unit that calculates an objective parameter corresponding to the norm y(t) of the actual position and the norm u(t) of the force on the basis of the base parameter, and sets the objective parameter as parameters of the interaction model and the force computation model.
