Abstract: In a system for controlling outboard motors each mounted on a boat and each having an internal combustion engine and a shift mechanism, an actuator driving at least one of the shift mechanism and a throttle valve of the engine, and a controller controlling operation of the actuator, comprising: a navigation unit having a steering wheel installed to be freely operable by an operator and a steering angle detector producing an output indicative of a steering angle of the steering wheel, wherein the outboard motors are immovably fastened to the boat, such that each of the controllers controls the operation of the actuator cooperatively based on the output of the steering angle detector, to regulate traveling direction of the boat. With this, it becomes possible to control a traveling direction of the boat based on a steering command issued by the operator, while achieving a compact outboard motor.

Abstract: In a system for controlling outboard motors each mounted on a boat and each having an engine, a steering mechanism, a shift mechanism, an actuator driving at least one of the steering mechanism, the shift mechanism and a throttle valve of the engine, and a controller controlling operation of the actuator, comprising: a steering wheel operable by an operator; a shift/throttle lever operable by the operator; and a manipulated variable detector producing an output indicative of manipulated variable of at least one of the steering wheel and the shift/throttle lever; the manipulated variable detector being separately connected to each of the controllers in the outboard motors through an electric signal line to send the output to the controllers. With this, it becomes possible to control the operation of the actuators in the outboard motors separately for the individual outboard motors with simple structure without identifying the respective outboard motors.

Abstract: In an apparatus for controlling a small boat having a hull and two outboard motors mounted on a stern of the hull and an actuator adapted to open/close a throttle valve of each engine of the motors for regulating speed of the engine, acceleration acting on the boat in a direction of gravity axis when the boat ascends or descends the ocean wave and angular acceleration about the gravity is detected and a correction amount of the engine speed is calculated based on the detected acceleration so as to change behavior of the boat, thereby mitigating a burden on the operator and improving stability of the boat.

Abstract: In an outboard motor conversion unit, it is configured to have a boat-side conversion unit that detects displacement generated at a movable member due to manual manipulation of a mechanical operation mechanism and converts the detected displacement into an electric signal, actuators connected to a steering mechanism, a shift mechanism and a throttle valve of an internal combustion engine of the outboard motor, and an actuator controller that controls operation of the actuators based on the converted electric signal. With this, the outboard motor installed at a boat with the mechanical operation mechanism can be easily converted to an electronically-operated outboard motor without newly installing a remote control unit or the like.

Abstract: In an outboard motor control system, an electronic control unit executes ordinary navigation in which the operation of at least one among a steering motor, throttle motor and shift motor is controlled in accordance with an operator command inputted from the steering wheel or shift/throttle lever (steering command, shift position change command or engine speed regulation command of the outboard motor) and executes autopilot navigation in which the boat is automatically navigated by controlling the operation of the individual electric motors based on boat position information inputted from a GPS plotter and the desired position of the boat. This simplifies the configuration for conducting both manual navigation and automatic navigation and avoids making the system larger or more complicated to install, while including boat speed regulation and stopping capability among the autopilot features.
