Abstract
A method and a device for coupling piloting members (20, 50), wherein saturation values (SCpsat−, SCpsat+, SCcopsat−, SCcopsat+) of at least one force saturator (28, 58) are adapted such that a force-feedback is exerted for each of these saturation values at a force-feedback value, taken at the force application centre of the manoeuvring handle (21, 51), of between 4 daN and 40 daN, with the result that a function of disconnecting is at least in part performed by the at least one force saturator.
Claims16
A method for coupling piloting members, the method comprising:—a servo device delivering a respective control signal to each piloting member,
- wherein each piloting member comprises i) a manoeuvring handle which is movable in relation to an underframe and has a force application center, and ii) at least one force actuator which is suitable for exerting a force, named a force-feedback, on the manoeuvring handle of the piloting member, and
- wherein the servo device delivers the respective control signal to each force actuator of each piloting member,
- each force actuator exerting the force-feedback on each manoeuvring handle at a force-feedback value determined by the respective control signal supplied to each force actuator of the piloting member, at a value (SCp, SCcop) of the respective control signal that is determined by the servo device to ensure a coupling link between the piloting members,
- at least one saturator of the servo device, named at least one force saturator, limiting the value (SCp, SCcop) of each respective control signal so that the value (SCp, SCcop) of each respective control signal remains within a range of values [SCpsat−, SCpsat+], [SCcopsat−, SCcopsat+] delimited by a lower saturation value (SCpsat−, SCcopsat−) and an upper saturation value (SCpsat+, SCcopsat+),
- when disconnection conditions are met, performing a function of disconnecting the piloting members,
- wherein the lower and upper saturation values provide that the force-feedback is exerted at a force-feedback value, taken at the force application center of the manoeuvring handle, of between 4 daN and 40 daN, with the result that the function of disconnecting is determined exclusively by the at least one force saturator limiting the value (SCp, SCcop) of the respective control signals so that the value (SCp, SCcop) of each respective control signal remains within the range of values [SCpsat−, SCpsat+], [SCcopsat−, SCcopsat+] delimited by the lower and upper saturation values (SCpsat−, SCcopsat−;
- SCpsat+, SCcopsat+).

A device for coupling between piloting members, comprising:
- a servo device connected to the piloting members, each piloting member comprising:
- a manoeuvring handle which is movable in relation to an underframe and has a force application center,—at least one force actuator which is suitable for exerting a force, named a force-feedback, on the manoeuvring handle of the piloting member,
- wherein the servo device delivers a respective control signal to each force actuator of each piloting member,
- the force-feedback being exerted on each manoeuvring handle at a force-feedback value determined by the control signal supplied to each force actuator of the piloting member, at a value (SCp, SCcop) of the respective control signal that is determined by the servo device to ensure a coupling link between the piloting members,
- at least one saturator, named the force saturator, that limits the value (SCp, SCcop) of the respective control signal of each piloting member such that the value (SCp, SCcop) of each respective control signal remains within a range of values [SCpsat−, SCpsat+], [SCcopsat−, SCcopsat+] delimited by a lower saturation value (SCpsat−, SCcopsat−) and an upper saturation value (SCpsat+, SCcopsat+),
