<P>PROBLEM TO BE SOLVED: To provide a control apparatus of multiple ship propellers capable of turning a ship only by operation of a steering wheel, without making a pilot perform complicated operation of an accelerator lever, even if a rudder cannot be moved, when an electric steering device causes failure, when the multiple ship propellers are provided. <P>SOLUTION: This control device includes a communication line 8 for mutually transmitting and receiving operation information on respective outboard motors 5a and 5b, and imparts a thrust difference by controlling thrust of the respective outboard motors 5a and 5b in response to a detecting value of a steering angle sensor 3 for detecting a steering angle when the electric steering devices 7a and 7b for steering a hull cause failure. When controlling the traveling direction of the hull by the thrust difference, the traveling direction is controlled by a steering angle threshold value of not imparting the thrust difference in a small area of the steering angle, and is controlled by a thrust difference predetermined value of imparting the thrust difference when exceeding the steering angle threshold value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
