Steering control device for a work vehicle

A steering control device for a work vehicle, comprising:

• a traveling body capable of traveling with a steered wheel,
• a work equipment provided on the traveling body,
• a steering operation tool, which is biased to be located at a neutral position in a non-operation status, for making a steering operation by being displaced from the neutral position,
• a steering angle detector for detecting a steering angle of the steered wheel,
• a steering actuator for changing the steering angle of the steered wheel, and
• a steering control unit for controlling an operation of the steering actuator so that a steering angle of the steered wheel detected by the steering angle detector becomes a target steering angle corresponding to a steering position of the steering operation tool, wherein
• when the steering operation tool has been displaced from the neutral position to a steering operation range and then has been moved back to the neutral position,
• if a maximum steered angle of the steered wheel detected by the steering angle detector is within a predetermined steering angle range, the steering control unit controls the steering actuator to stop actuation of the steering actuator to maintain the steering angle of the steered wheel at a present steering angle existing when the steering operation tool has been moved back to the neutral position, and
• if a maximum steered angle of the steered wheel detected by the steering angle detector exceeds the predetermined steering angle range, the steering control unit controls the steering actuator to control the steering angle of the steered wheel to move back to a neutral steering angle in correspondence with moving the steering operation tool back to the neutral position.
