Patent ID: 8452468

Claim:
A steering system for a vessel in which at least one outboard engine is installed, said steering system comprising: a steering wheel configured to receive an instruction of a steering direction; a steering wheel sensor configured to detect an operation angle of the steering wheel; an actuator configured to turn the outboard engine; a plurality of turn angle sensors including a first turn angle sensor configured to detect a turn angle of the outboard engine turned by the actuator; and a control unit configured to calculate a controlling turn angle for driving the actuator to turn the outboard engine based on the operation angle, and to drive the actuator to turn the outboard engine in accordance with a difference between the controlling turn angle and the turn angle, wherein if an anomaly of the first turn angle sensor is detected, the control unit continues to drive the actuator to turn the outboard engine based on information from a second turn angle sensor of the plurality of turn angle sensors which is in a normal state, and drives the actuator so as to limit the turn angle of the outboard engine as compared with a case in which the first turn angle sensor is in a normal state.
