Abstract

A work vehicle includes a hydraulic actuator, a control valve, a pressure sensing unit, a force imparting component, and a controller. The hydraulic actuator varies a steering angle. The control valve controls flow of fluid supplied to the hydraulic actuator. The operation member is configured to be operated by an operator and to control the control valve when varying the steering angle. The pressure sensing unit senses a pressure produced by the hydraulic actuator. The force imparting component imparts an assisting force or a counterforce to operation of the operation member. The controller controls the force imparting component so as to generate resistance to operation of the operation member based on a pressure value sensed by the pressure sensing unit.
