Outboard motor control device, outboard motor control method, and program

An outboard motor control method of controlling a plurality of outboard motors disposed on a rear portion of a hull of a boat,

• wherein each of the plurality of outboard motors comprises a propulsion unit configured to generate a propulsion force and a steering actuator,
• wherein the boat comprises an operation unit configured to operate the steering actuator and the propulsion unit and an outboard motor control device configured to control the plurality of outboard motors,
• wherein the operation unit is able to be positioned at least at a first position that is a position where the plurality of outboard motors do not generate a propulsion force of the boat and a second position that is a position where the plurality of outboard motors generate a propulsion force for moving the boat in a left-right direction, and
• wherein the outboard motor control method comprises:
• a first step in which the outboard motor control device causes the plurality of outboard motors to generate a first propulsion force during a first period from a first timing when the operation unit is moved to the second position to a second timing when the operation unit is moved from the first position to the second position and maintained at the second position;
• and
• a second step in which the outboard motor control device causes the plurality of outboard motors to generate a second propulsion force greater than the first propulsion force during a second period after the second timing when the operation unit is moved from the first position to the second position and maintained at the second position.

A program for controlling a plurality of outboard motors disposed on a rear portion of a hull of a boat,

• wherein each of the plurality of outboard motors comprises a propulsion unit configured to generate a propulsion force and a steering actuator,
• wherein the boat comprises an operation unit configured to operate the steering actuator and the propulsion unit,
• wherein the operation unit is able to be positioned at least at a first position that is a position where the plurality of outboard motors do not generate a propulsion force of the boat and a second position that is a position where the plurality of outboard motors generate a propulsion force for moving the boat in a left-right direction, and
• wherein the program causes a computer mounted in the boat to execute:
• a first step in which the plurality of outboard motors generate a first propulsion force during a first period from a first timing when the operation unit is moved to the second position to a second timing when the operation unit is moved from the first position to the second position and maintained at the second position;
• and
• a second step in which the plurality of outboard motors generate a second propulsion force greater than the first propulsion force during a second period after the second timing when the operation unit is moved from the first position to the second position and maintained at the second position.
