In a device for controlling elements of a machine, comprising two control members of the joy stick type from one or other of which said elements may be controlled, these members being intended to be actuated by separate operators and each being mounted for tilting about at least one axis and connected to at least one sensor delivering an electric signal representative of the amplitude of tilt of the associated joy stick about said axis on each side of a neutral position, a signal processing system is provided receiving the signals from two sensors and delivering a single control reference addressed to said controlled elements of the machine.

A device for controlling elements of a machine which is capable of control by two pilots, comprising: two control members of the joy stick type, from one or other of which said elements can be controlled, these members being intended to be actuated by separate pilots, and each being mounted for tilting about at least one axis; sensors connected to said control members and each delivering an electric signal representative of the amplitude of tilt of the associated joy stick about said axis on each side of a neutral position; a signal processing system receiving these signals from said sensors and delivering a single control reference to said controlled elements of the machine; said signal processing system including comparator means for comparing said signals from the sensors with reference signals, in such a way that said single control reference is: zero when the two joy sticks are in the neutral position; equal to the signal corresponding to a joy stick moved away from its neutral position when the other joy stick is in the neutral position; equal to the sum of the signals of the two sensors when the tilting of the two joy sticks is in the same direction, this sum being limited to the maximum signal able to be emitted by each separate joy stick; equal when, with a first pilot having tilted his joy stick in one direction, the second pilot tilts his joy stick in the oposite direction but short of a travel threshold, to the difference between the signal emitted by the sensor associated with the first pilot and that emitted by the sensor associated with the second pilot; and equal to the difference between the signal emitted by the sensor associated with the second pilot and a fraction of that emitted by the sensor associated with the first pilot when, with a first pilot having tilted his joy stick in one direction, the second pilot tilts his joy stick in the opposite direction beyond said travel threshold.
