Electromechanical control system, particularly for marine applications
First Claim
1. An electromechanical control system for watercrafts, motorboats, ships or the like, having at least:
- a control station, an engine, an electromechanical actuator associated to said engine, a signal transmission device for transmitting a control signal generated by the control station to an electronic control and monitoring unit as a function of the control signal and transmitted to said electromechanical actuator for actuating the signal, and further having a signal transmission device for transmitting an actuating signal, generated by the electronic control and monitoring unit as a function of the control signal and transmitted to said electromechanical actuator for actuating the control, wherein said electronic control and monitoring unit establishes a unique correspondence between the control signal and the actuating signal by using a table of correspondence between discretized values of control signals and actuating signals and/or by determining the actuating signal value from the control signal by means of a mathematical function.

16. A method for controlling the throttle opening in a marine engine, wherein it includes the steps of:
-
setting an angular position (BETA) of a control lever;
using the value of said angular position (BETA) ad the argument of a mathematical function ALFA=f(BETA);
carrying out the mathematical computation to determine the result ALFA displacing a lever which actuates the fuel-air mixture flow control means and/or displacing a device for metering or controlling said flow and/or opening the throttle to an extent corresponding to an angular displacement equal to the result (ALFA) as determined by the mathematical function ALFA=f(BETA).

17. A method for controlling the throttle opening in a marine engine, wherein it includes the steps of:
-
setting an angular position (BETA) of a control lever;
comparing the value of said angular position (BETA) with a table of correspondence between the angular position (BETA) of the control lever and the angular position (ALFA) of a lever for actuating the fuel-air mixture flow control means and/or a device for metering or controlling said flow and/or a throttle. determining the value of the angular position (ALFA) of a lever for actuating the fuel-air mixture flow control means and/or a device for metering or controlling said flow and/or a throttle, which corresponds to the value of the angular position (BETA) of the control lever in the table of correspondence;
displacing a lever which actuates the fuel-air mixture flow control means and/or displacing a device for metering or controlling said flow and/or opening the throttle in the angular position (ALFA) as an extent corresponding to an angular displacement equal to the result (ALFA) as determined by the mathematical function ALFA=f (BETA).
