摘要： A vessel steering system is provided with a control unit that calculates a control pivoting angle for pivoting the propulsion means based on a steering angle. Based on actual-state recognition of at least one of the type of the vessel, the type of the propulsion means, an actual pivoting angle of a neighboring propulsion means that is close to the propulsion means when a plurality of propulsion means is provided, the distance between the swivel shaft of a reference propulsion means and the swivel shaft of a neighboring propulsion means thereof at a time when a plurality of propulsion means is provided, and the mounting position of the propulsion means on the vessel, the control unit sets a pivoting limit angle for limiting the pivoting of the propulsion means, and controls the pivoting apparatus in such a way that the propulsion means does not pivot by more than the set pivoting limit angle.

摘要： A communication unit receives from a BCM output data which is data to I/O devices from the BCM. A shared memory stores the output data received by the communication unit. An anomaly detection communication processing unit and the communication unit generate a communication frame for anomaly detection to request sending the output data held in the BCM. The communication unit sends the communication frame for the anomaly detection to the BCM, and receives the output data held in the BCM from the BCM as a response to the communication frame for the anomaly detection. The anomaly detection checking unit compares the output data received from the BCM with the output data stored in the shared memory.

摘要： A control device controls the operating state of each of a plurality of propulsion machines arranged in parallel in a marine vessel. Control devices are connected to each other by a communication line through which operating information of the propulsion machine is mutually transmitted and received. The control device includes a unit which determines the installation position of a corresponding propulsion machine, a unit which determines the connection state of another propulsion machine connected to the communication line, and a unit which determines a propulsion machine as a control reference from among a plurality of control devices. The propulsion machine as a control reference is switched to a propulsion machine which is arbitrarily designated by an operator or a propulsion machine which has the highest priority as a control reference.

摘要： A control apparatus controls multiple outboard motors transmitting and receiving operation information mutually via a communication line and is configured to give a thrust difference between the outboard motors in the event of a fault of an electric rudder tilter used to turn a ship by turning a rudder by controlling thrusts of the outboard motors according to a detection value of a steering angle sensor detecting a steering angle. When a ship sailing direction is controlled by the thrust difference, the control apparatus controls the outboard motors by using a steering angle threshold up to which the thrust difference is not given between the outboard motors in a region where a steering angle is small, and in a case where the steering angle exceeds the steering angle threshold, by using a predetermined value of the thrust difference with which the thrust difference is given between the outboard motors.
