Abstract
A steering system for a vessel includes an electric actuator that generates power to rotate a steering wheel, a transmitting mechanism that transmits a rotation of the electric actuator to the steering wheel, and a power supply controller that supplies electric power to the electric actuator according to an input signal that is not based on a rotation of the steering wheel.
Claims19
A steering system for a vessel, the steering system comprising:
- an electric actuator that generates power to rotate a steering wheel;
- a transmitting mechanism including a driving member that rotates together with an output portion of the electric actuator and a driven member that rotates together with the steering wheel, the transmitting mechanism transmits a rotation of the output portion of the electric actuator to the steering wheel;
- and
- a power supply controller that supplies electric power to the electric actuator according to an input signal that is not based on a rotation of the steering wheel;
- wherein
- a maximum torque that is transmitted from the electric actuator to the steering wheel is about 8 Nm or less.
