Marine vessel propulsion system and marine vessel including the same
First Claim
1. A marine vessel propulsion system comprising:
- a plurality of propulsion devices arranged to be mounted on a hull so as to enable a steering angle to change;
a plurality of operation levers arranged to be operated by a marine vessel maneuvering operator to control the plurality of propulsion devices to have respective shift states selected from among a forward drive state, a neutral state, and a reverse drive state;
a plurality of lever position sensors provided to correspond to the plurality of respective operation levers and arranged to detect positions of the plurality of operation levers;
a storage unit arranged to store therein behavior patterns of the hull preset to correspond to positional relationships between the plurality of operation levers; and
a control unit programmed to select among the behavior patterns based on detection results from the plurality of lever position sensors, and to control the steering angles and shift states of the plurality of respective propulsion devices to correspond to the selected behavior pattern.

Abstract
A marine vessel propulsion system includes first and second propulsion devices, a first operation lever arranged to be operated by a marine vessel maneuvering operator to control the first propulsion device, a second operation lever arranged to be operated by the marine vessel maneuvering operator to control the second propulsion device, a first lever position sensor arranged to detect a position of the first operation lever, a second lever position sensor arranged to detect a position of the second operation lever, and a control unit. The control unit is programmed to set a target pivoting speed according to the positions of the first and second operation levers relative to each other and set a target travel speed according to amounts of displacement of the first and second operation levers with respect to neutral positions.
