Abstract
A control unit in a work vehicle executes an automatic downshift for shifting a speed range of a transmission to the speed range at a lower speed than a current speed range. The control unit determines the execution of the automatic downshift on the basis of automatic downshift conditions. The automatic downshift conditions include whether the operating amount of the accelerator operating member is equal to or greater than a predetermined accelerator threshold, whether the vehicle speed is less than a predetermined speed threshold, and whether the acceleration is equal to or less than a predetermined acceleration threshold.
