The force imparting component is configured to impart an assist force or a counterforce to operation of the joystick lever by the operator. The speed sensor is configured to sense speed of the work vehicle. The controller is configured to control the force imparting component so as to impart the assist force or the counterforce according to the speed sensed by the speed sensor.
