1. A method to control a work vehicle, having a boom supported by a vehicle body and configured to turn; and a bucket supported by a side of the boom and configured to turn according to an operation of an actuator, the method comprising:
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.
