First Claim
Patent Images
1. A steering system for a boat, comprising:
- operation angle detection means for detecting an operation angle of a handle;
control means for receiving a detection signal from the operation angle detection means; and
electric drive means for receiving a control signal from the control means to drive a steering member to a predetermined rotation angle corresponding to the operation angle,wherein the control means receives a signal from a boat speed detection means for detecting a boat speed to control an upper limit of the rotation angle to be smaller when the boat speed is higher than a predetermined value than when not.

Abstract
A rudder control device for a boat can include a handle position sensor for detecting an operation angle of a handle. An engine control unit can be provided for receiving a detection signal from the handle position sensor. A motor can be provided for receiving a control signal from the engine control unit to drive a steering member to a predetermined rotation angle corresponding to the operation angle. The engine control unit can receive a signal from a speed sensor for detecting a boat speed to control an upper limit of the rotation angle to be smaller when the boat speed is higher than a predetermined value than when not.

2. A steering system for a boat, comprising:
-
operation angle detecton means for detecting an operation angle of a handle; control means for receiving a detection signal from the operation angle detection means; and drive means for receiving a control signal from the control means to drive a steering member to a predetermined rotation angle corresponding to the operation angle, wherein the control means receives a signal from a boat speed detection means for detecting a boat speed to control a change rate of the rotation angle to the operation angle to be smaller when the boat speed is higher than a predetermined value than when not.

- 3. A steering system for a boat comprising a steering command sensor configured to detect steering commands from an operator of the boat and to output a steering command signal, a control device configured to receive the steering command signal from the steering command sensor and to output a control signal, an electric drive device configured to receive the control signal from the control device to drive a steering member to a predetermined rotation angle corresponding to the steering command, a boat speed detection device configured to detect a speed of the boat, and a steering member configured to control a direction of travel of the boat, wherein the control device is configured to allow the steering member to be moved through its full range of movement when the boat speed is below a first predetermined angle, and to limit the proportion of movement of the steering member to a magnitude of the steering command signal when the boat speed is higher than a first predetermined value.
