Work vehicle and control method for work vehicle

A method for controlling a work vehicle that includes:

• an engine;
• a hydraulic actuator configured to change a steering angle of the work vehicle in response to a fluid supplied to the hydraulic actuator;
• a hydraulic pump configured to supply the fluid to the hydraulic actuator;
• an operating member configured to be operated by an operator of the work vehicle to change the steering angle;
• a control valve configured to control a flow of the fluid supplied from the hydraulic pump to the hydraulic actuator, based on an amount the operating member is operated;
• an angular velocity corresponding value sensing unit comprising a tachometer and a first sensor, the tachometer being configured to detect a rotational speed of the engine and the first sensor being configured to detect a first value related to a discharge flow rate of the hydraulic pump;
• a controller arranged to receive a signal indicating the rotational speed of the engine from the tachometer and a signal indicating the first value from the first sensor;
• and
• a notification component configured to perform a notification to notify the operator regarding the first value,
• the method comprising utilizing the controller to:
• acquire the rotational speed of the engine and the first value;
• determine whether the first value has reached a threshold value set based on a relationship indicating the discharge flow rate of the hydraulic pump with respect to the rotational speed of the engine;
• and
• cause the notification component to notify the operator that the first value has reached the threshold value when it is determined that the first value has reached the threshold value.
