Abstract

A control system to control an operation of a power transmission of a work vehicle includes a storage to store data indicating a relationship between a ratio between a rotational speed of a predetermined component on a power transmission path to transmit the rotation of the planetary transmission to wheels and a rotational speed of the internal combustion engine, and switching points at which the transmission gear of the planetary transmission is switched, and a controller to control the hydraulic clutch mechanism to perform switching of the transmission gear. Where the transmission gear is switched when the ratio changes to reach a first value corresponding to a first switching point or after the ratio reaches the first value, the controller controls the hydraulic clutch mechanism so as to start hydraulic fluid charging to perform switching of the transmission gear before the ratio reaches the first value.
