Abstract
Official abstract text for this publication.
In a ship steering system for an out-drive device including: an out-drive device; a hydraulic actuator configured to turn the out-drive device; a hydraulic controller configured to control the hydraulic actuator; a ship steering device configured to instruct a traveling direction to the hydraulic controller; and an emergency ship steering device capable of at least instructing the out-drive device to turn, the emergency ship steering device is capable of controlling the hydraulic actuator without involving the hydraulic controller.
First claim
Opening claim text (preview).
The invention claimed is: 1. A ship steering system for an out-drive device comprising: an out-drive device; a hydraulic actuator configured to turn the out-drive device; a hydraulic controller configured to control the hydraulic actuator; a ship steering device configured to instruct a traveling direction to the hydraulic controller; and an emergency ship steering device capable of at least instructing the out-drive device to turn by controlling the hydraulic actuator without involving the hydraulic controller; and, an electromagnetic hydraulic control valve configured to change a flowing direction of hydraulic oil to the hydraulic actuator; wherein the emergency ship steering device is configured to control the hydraulic actuator by operating the electromagnetic hydraulic control valve. 2. The ship steering system for an out-drive device according to claim 1 further comprising a connection terminal configured to detachably connect between wiring of the emergency ship steering device and wiring of the electromagnetic hydraulic control valve, wherein the connection terminal enables the emergency ship steering device to be detachable from the electromagnetic hydraulic control valve. 3. The ship steering system for an out-drive device according to claim 1 further comprising a connection terminal configured to detachably connect between wiring of the hydraulic controller and wiring of the electromagnetic hydraulic control valve, wherein the emergency ship steering device becomes available when the wiring of the emergency ship steering device is connected to the wiring of the electromagnetic hydraulic control valve through the connection terminal. 4. The ship steering system for an out-drive device according to claim 1 further comprising a main controller configured to be capable of recognizing failure of the hydraulic controller, wherein the emergency ship steering device becomes available when the main controller recognizes the failure of the hydraulic controller. 5. The ship steering system for an out-drive device according to claim 2 further comprising a main controller configured to be capable of recognizing failure of the hydraulic controller, wherein the emergency ship steering device becomes available when the main controller recognizes the failure of the hydraulic controller.
