摘要:
In an apparatus for controlling an outboard motor (10) having an internal combustion engine (30) to power a propeller (60), and a torque converter (44) interposed between the engine and a drive shaft (42) and equipped with a lockup clutch (44d), it is configured to have a throttle opening detector (80, 94, S12) that detects throttle opening TH of a throttle valve (38) of the engine, a throttle opening change amount calculator (94, S14) that calculates a change amount DTH of the calculated throttle opening, and a clutch ON unit (94, S20 to S28) that makes the lockup clutch ON when the calculated change amount is equal to or greater than a predetermined value DTHref, and keeps the lockup clutch ON during a predetermined time period (tm). With this, it becomes possible to improve acceleration performance immediately after the engine speed is accelerated.

In an apparatus for controlling operation of an outboard motor (10) mounted on a boat (12) and having a torque converter (44) equipped with a lockup clutch (44d), it is configured to regulate a trim angle relative to the boat by trim-up operation and trim-down operation; calculate a speed ratio e of the torque converter based on an input rotation speed and output rotation speed of the torque converter (S10, S10a, S120, S122, S420, S422); and control operation of the trim angle regulator based on the calculated speed ratio. With this, it becomes possible to mitigate a deceleration feel to be generated after the acceleration is completed, and easily sets a trim angle of after the trim-up operation to an optimal value.

In an apparatus for controlling operation of an outboard motor having an internal combustion engine, transmission and trim angle regulation mechanism, it is configured to change a gear position to the first speed when the gear position is in the second speed and a throttle opening change amount is at or above a predetermined value (S10, S120, S126, S420, S426), start trim-up operation when the engine speed is at or above a first predetermined speed after the gear position is changed to the first speed (S10, S 12, S130, S200, S204, S208, S24, S430, S904, S906, S910), change the gear position from the first speed to the second speed when the engine speed is at or above a second predetermined speed after the trim-up operation is started (S10, S116, S134, S416, S434), and stop the trim-up operation after the gear position is changed to the second speed (S10, S12, S140, S200, S202, S24, S908, S914). It can mitigate a deceleration feel generated when the gear position is changed upon the completion of the acceleration and prevent the pitching occurrence.
