Claims

[Scope of utility model registration request]

The ship's S/D conversion device digitally converts the steering angle detected by the rudder angle indicator and the course obtained from the gyro compass, and the difference between the planned course input from the planned course input device and the actual course. The steering angle frequency and planned course deviation angle frequency detection device detects the deflection angle and steering angle of the vehicle, a display device, an arithmetic circuit, a warning device, and an automatic steering device. In addition, the maximum or minimum value of the deflection angle is sequentially obtained, and based on this data, the steering angle adjustment coefficient and the guessing rudder adjustment coefficient for optimal automatic steering are determined by an arithmetic circuit. Set rudder adjustment automatically,
An automatic steering system for a ship, characterized in that when the deviation angle of the ship reaches a certain value, an alarm device automatically issues a warning to an operator.
