Title:
自車位置算出システム
Document Type and Number:
Japanese Patent JP7101579
Kind Code:
B2
Abstract:
To provide a vehicle self-position calculation system with which disturbance in a traveling trajectory during autonomous cruising is suppressed as much as possible, even when satellite signals from one or more satellites become unreceivable.SOLUTION: The vehicle self-position calculation system comprises: a satellite state determination unit 72 for determining, from the receive state of satellite signals in a satellite signal receive unit 71 that receives satellite signals from a plurality of satellites, normally receivable satellites with which the satellite signals are receivable normally, and creating normally receivable satellite information relating to normally receivable satellites that includes the number of normally receivable satellites; a receive position computation unit 73 for computing a receive position from the satellite signals using a computation formula selected on the basis of the normally receivable satellite information; a positioning data output unit 75 for outputting positioning data; and a vehicle self-position calculation unit 50 for calculating the vehicle self-position of a work vehicle on the basis of the positioning data.SELECTED DRAWING: Figure 4
