Abstract
Official abstract text for this publication.
In controlling a work vehicle including a boom supported by a vehicle body and configured to turn, and a bucket supported by a side, away from the vehicle body, of the boom and configured to turn according to an operation of an actuator, an operation amount for raising the boom or a rising speed of the boom, and an operable amount that the actuator is able to operate before the bucket reaches a stop position on the dump side based on the posture of the boom and the posture of the bucket, are obtained, and an operation amount of the actuator for causing the bucket to tilt is changed based on the operation amount for raising the boom or the rising speed of the boom to thereby cause the bucket to tilt according to the operable amount.
First claim
Opening claim text (preview).
1 . A work vehicle control method comprising, in controlling a work vehicle including a boom supported by a vehicle body and configured to turn; and a bucket supported by a side, away from the vehicle body, of the boom and configured to turn according to an operation of an actuator: obtaining an operation amount for raising the boom or a rising speed of the boom and an operable amount that the actuator is able to operate before the bucket reaches a stop position on a dump side, the operable amount being obtained based on a posture of the boom and a posture of the bucket; and causing the bucket to perform tilting by operating the actuator from a position where the operable amount is large such that the operable amount becomes larger as the operation amount for raising the boom is larger or the rising speed of the boom is higher. 2 . The work vehicle control method according to claim 1 , further comprising in a case where the boom is raised and a device for operating the bucket is in a neutral state, causing the bucket to perform tilting according to the operable amount. 3 . A work vehicle control device which controls a work vehicle including a boom supported by a vehicle body and configured to turn; and a bucket supported by a side, away from the vehicle body, of the boom, and configured to turn according to an operation of an actuator, wherein the work vehicle control device obtains an operation amount for raising the boom or a rising speed of the boom, and an operable amount that the actuator is able to operate before the bucket reaches a stop position on a dump side, the operable amount being obtained based on a posture of the boom and a posture of the bucket, and the work vehicle control device causes the bucket to perform tilting by operating the actuator from a position where the operable amount is large such that the operable amount becomes larger as the operation amount for raising the boom is larger or the rising speed of the boom is higher. 4 . The work vehicle control device according to claim 3 , wherein in a case where the boom is raised and a device for operating the bucket is in a neutral state, the work vehicle control device causes the bucket to perform tilting according to the operable amount. 5 . A work vehicle comprising: a boom supported by a vehicle body and configured to turn; a bucket supported by a side, away from the vehicle body, of the boom, and configured to turn according to an operation of an actuator; and the work vehicle control device according to claim 3 .
