Device for combining force among control units, control unit and aircraft
First Claim
1. An effort couple device comprising:
- a first input connected to a first effort feedback piloting member (20);
a second input connected to a second effort feedback piloting member (30),each piloting member having i) at least one effort sensor (24, 34) adapted to supply a value of an effort, called piloting effort (Fp, Fcp), exerted by a pilot, and ii) an operating handle (21,31) movable with respect to a frame (40) and with respect to the at least one effort sensor (24, 34) so that the at least one effort sensor (24, 34) supplies a signal representing the value of effort exerted by the pilot on the operating handle to a respective one of the first and second inputs;
means adapted to form an effort feedback value (Fcor_p) from a sum of the values of the piloting efforts of each piloting member; and
a correcting device adapted to limit said effort feedback value (Fcor_p) as a function of at least one parameter taken from among the value of the piloting effort (Fcp) of said second piloting member and the difference between the piloting effort values of each piloting member.

Abstract
A device for combining force between two control units includes force feedback, each control unit including a control stick (21, 31) and at least one force sensor (24, 34) suitable for providing a value of the control force (Fp, Fcp) exerted by a pilot, the device being suitable for forming a force feedback value from the sum of the values of the control forces of each control unit. A correction device limits the force feedback value (Fcor_p) according to at least one parameter taken from the absolute value of the control force (Fcp) of the second control unit and the difference between the control force values of each control unit. A control unit including such a device for combining forces, and an aircraft provided with such control units are also described.
