Steering control system for boat
First Claim
1. A steering control system for a boat provided externally of its hull with a steering device rotatable by an electric actuator to change a navigation direction, comprising:
- a steering system electrically connected to the steering device via the electric actuator to operate the steering device;
external force detection means for detecting external force applied to the steering device;
a reaction torque motor for applying torque to the steering system; and
control means which monitors a detection state of the external force detection means, and causes the reaction torque motor to apply pulsed torque when the external force detection means detects that an amount of variation in the external force is a predetermined value or larger.

Abstract
A load variation amount can be derived from an output of a load sensor for detecting an external force acting on a watercraft. A computation can be performed whether or not the load variation amount is larger than a reference value calculated based on the load sensor output, a running state, and a navigation velocity. The width and the magnitude of a pulse are determined based on the load sensor output, the running state, and the navigation velocity, and the pulse is applied to a steering as reaction torque.
