Electric type steering device for outboard motors
First Claim
1. An electric type steering device for a plurality outboard motors, comprising:
- a steering wheel;
a connecting member for connecting outboard motors together so that the steering movements of a plurality of outboard motors are linked together;
a plurality of electric steering motors configured to steer the plurality of outboard motors;
a target steering angle setting device configured to obtaining a target steering angle according to a steering displacement of the steering wheel and an actual steering unit angle detecting device configured to detecting an actual steering unit angle of each of the outboard motors;
a correcting device configure to obtain a difference between actual steering unit angles of at least two of the plurality of outboard motors, to correct a target steering angle of each outboard motor according to this difference, and to obtain a target steering angle of each outboard motor; and
a motor controlling device configured to control the electric steering motor so that the target steering angle of each of the outboard motors agrees with the actual steering unit angle.

Abstract
A steering device can include a steering wheel, connecting members for connecting outboard motors together, and a plurality of steering motors for steering a plurality of outboard motors. A target steering angle setting device can be configured to obtain a steering angle according to a steering displacement of the steering wheel, and steering unit angle sensor can be configured to detect actual steering unit angles of the respective outboard motors. A correcting device can be configured to obtain the difference between actual steering unit angles of the outboard motors, to correct the target steering angles so that the difference becomes, and to obtain a target steering angle of each of the outboard motors. Motor controlling device can be configured to control the steering motors so that a target steering angle agrees with the actual steering unit angle for each of the outboard motors.
