摘要： PROBLEM TO BE SOLVED: To provide a steering device for a marine vessel capable of eliminating the deviation of phase between two operation means of a steering angle and a turning angle and smoothly performing switching between those operation means, and a marine vessel provided with the device. SOLUTION: The marine vessel 1 includes: a steering wheel 5a; a controller 6; a turning mechanism 4; and an outboard motor 3. The steering angle θ of the steering wheel 5a is detected by a steering angle sensor 5b. The turning angle δ of the turning mechanism 4 is detected by a turning angle sensor 30. The controller 6 executes turning control for controlling the turning mechanism 4 according to the steering angle θ. At activation, the controller 6 determines whether or not the phase of the steering angle θ and the turning angle δ is deviated. When the phase is deviated, the controller 6 delays the starting of the turning control until the deviation of the phase is eliminated by the operation of the steering wheel 5a. A delay of the turning control is informed to an operator by the flashing of the drive of an indicator 7. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an outboard motor control system capable of preventing, a rudder angle difference from being increased in a vessel equipped with a plurality of outboard motors with independently settable rudder angles.SOLUTION: An outboard motor control system includes: a plurality of outboard motors 3a, 3b; a target rudder angle setting unit; a plurality of actuators; an actual rudder angle detection unit; and a control unit. The plurality of outboard motors are attached to the stern of a vessel. The outboard motors can be independently steered. The target rudder angle setting unit sets a target rudder angle of each outboard motor. The plurality of actuators actuate steering operations of the outboard motors, respectively, so that the rudder angle of each outboard motor becomes a target rudder angle. The actual rudder angle detection unit detects the actual rudder angle of each outboard motor. When the rudder angle difference (difference between the actual rudder angles of the adjacently arranged outboard motors) is larger than or equal to a prescribed value, the control unit controls the steering operations of the outboard motors so as to avoid the rudder angle difference from being increased.

摘要： PROBLEM TO BE SOLVED: To enhance turning performance in a marine vessel provided with a plurality of outboard motors at a stern.
SOLUTION: A port outboard motor 3L and a starboard outboard motor 3R are mounted to the stern of the marine vessel. The port outboard motor 3L is turned by a port turning mechanism including a port turning motor 24L. The starboard outboard motor 3R is turned by a starboard turning mechanism including a starboard turning motor 24R. A controller 6 controls the turning motors 24L, 24R according to a steering angle of a steering wheel 5a. Functions of the controller 6 include functions as an individual turning angle setting unit 31 and an individual turning control unit 32. The function of the individual turning angle setting unit 31 individually sets a target turning angle of the outboard motors 3L, 3R so as to be a large turning angle as it advances to the outboard motor in a downstream side in a turning direction. The function of the individual turning control unit 32 controls the turning angle of the outboard motors 3L, 3R according to the individually set target turning angle.

SOLUTION: The marine vessel propulsion device (outboard motor 1) is provided with an forward-reverse switching mechanism unit 4 for switching between a transmitting state for transmitting the driving force of an engine 2 to a propeller 3 and a cut-off state for cutting off the driving force of the engine from the propeller 3; and an ECU 5 for electrically controlling a shift drive motor 4c of the forward-reverse switching mechanism unit 4. When a remote control lever 103 is operated from a first shift position to a second shift position, the ECU 5 starts engine speed decreasing control for temporarily decreasing the rotation speed of the engine 2. The ECU 5 controls a shift drive motor 4c of the forward-reverse switching mechanism unit 4 so as to start switching from the transmitting state to the cut-off state after a predetermined delay time is passed after starting the engine speed decreasing control.
