Propulsion unit control system

摘要

A propulsion unit control system is provided for a boat having plural propulsion units provided side by side and electrically connected in association with two adjacent operation levers. The control system synchronizes engine speeds of the respective propulsion units with each other in light of inputs to the two operation levers. The control system computes a deviation between the averaged engine speed of a reference propulsion unit and the averaged engine speed of a propulsion unit to be synchronized, and corrects a throttle opening of the propulsion unit to be synchronized based on the computed deviation in order to synchronize the engine speeds of the respective propulsion units with each other.

1. A propulsion unit control system for a boat including a plurality of propulsion units arranged side-by-side and electrically connected to two adjacent operation levers arranged to be controlled by an operator to operate shift actuators and/or throttle actuators of the plurality of propulsion units, the control system comprising:
an engine speed detecting device arranged to detect an engine speed of a reference propulsion unit and an engine speed of a propulsion unit to be synchronized; an averaging processing device configured to average the engine speed of the reference propulsion unit and the engine speed of the propulsion unit to be synchronized; and a control device configured to control the engine speed of the propulsion unit to be synchronized to synchronize the engine speed of the propulsion unit to be synchronized with the engine speed of the reference propulsion unit; wherein the control device is further configured to compute a deviation between the averaged engine speed of the reference propulsion unit and the averaged engine speed of the propulsion unit to be synchronized, and to correct a throttle opening of the propulsion unit to be synchronized based on the computed deviation in order to control and synchronize the engine speeds of the reference propulsion unit and the propulsion unit to be synchronized with each other.
