METHOD TO SELECT ACTUATORS IN SHIP COLLISION AVOIDANCE SYSTEM Russian patent published in 2010 - IPC B63H25/04 G05D1/00 

FIELD: marine transport.

SUBSTANCE: collision avoidance system selects actuate by using radar, propeller screw rpm controller, steering gear, satellite navigation system receiver, steering gear adder, logics unit and predictor. Predictor input receives signals of current latitude, longitude, heading angle and speed sent from satellite navigation system receiver and two signals from computer, i.e. ship speed correction value and preset heading angle correction value, to compute ship cruising time. Estimated ship cruising time signals are fed from predictor output into logics unit to select either propeller screw rpm controller to correct ship speed, or steering gear adder to correct preset heading angle.

EFFECT: optimum collision avoidance conditions.
