Abstract
A control apparatus for an outboard motor (4, 5) mounted on a hull (2), comprises a control unit (30, 40) that controls an attitude of the outboard motor (4, 5) with respect to the hull (2), and a detection unit (47, 49) that detects a counter electromotive force generated by an attitude change of the outboard motor (4, 5) due to an external force applied on the outboard motor (4, 5). The control unit (30, 40) determines that an object has collided with the outboard motor (4, 5) when the counter electromotive force that exceeds a predetermined threshold is detected.

A control apparatus for an outboard motor (4, 5) mounted on a hull (2), comprising:
- a control unit (30, 40) that controls an attitude of the outboard motor (4, 5) with respect to the hull (2);
- an actuator (26, 27) that is controlled by the control unit (30, 40), and
- a detection unit (47, 49) that detects a counter electromotive force generated when the actuator (26, 27) is forcibly operated due to the outboard motor (4, 5) being subjected to an external force,
- wherein the control unit (30, 40) determines that an object has collided with the outboard motor (4, 5) when a change in current value or voltage value with respect to a driving power for the actuator (26, 27) caused by the counter electromotive force exceeds a predetermined threshold.
A method of controlling an outboard motor (4, 5) mounted on a hull (2), comprising:
- controlling an actuator (26, 27) and an attitude of the outboard motor (4, 5) with respect to the hull (2);
- and
- detecting a counter electromotive force generated when the actuator (26, 27) is forcibly operated due to the outboard motor (4, 5) being subjected to an external force,
- wherein the controlling determines that an object has collided with the outboard motor (4, 5) when a change in current value or voltage value with respect to a driving power for the actuator (26, 27) caused by the counter electromotive force exceeds a predetermined threshold.
