Steering method and steering system for boat
First Claim
1. A method for steering a boat with a marine propulsion unit at the stern, in which a reaction torque is applied to a steering wheel in response to external force to the boat, the method comprising:
- detecting a steering angle and the behavior of the boat;
determining whether or not the turning of the steering wheel is in an initial phase based on the detected steering angle and the behavior of the boat; and
applying the reaction torque to the steering wheel in response to the determination.

Abstract
A steering method for a boat with a marine propulsion unit at the stern is provided in which a reaction torque is applied to a steering wheel in response to external force to the boat. The steering method includes: detecting a steering angle and the behavior of the boat; determining whether or not the turning of the steering wheel is in an initial phase based on the detected steering angle and the behavior of the boat; and applying the reaction torque to the steering wheel in response to the determination.

4. A steering system for a boat, comprising:
-
a marine propulsion unit mounted to the stern through a steering device;
a reaction motor configured to apply a reaction torque to a steering wheel of the boat in response to external force to the boat;
a steering angle sensor;
a boat behavior detection device; and
a controller configured to determine the reaction torque, the controller also being configured to determine whether or not the turning of the steering wheel is in an initial phase based on a steering angle and the behavior of the boat, and to determine the reaction torque based on the whether or not the steering wheel is in an initial phase.
