Abstract

An interface system between a user and a display device in the cockpit of an aircraft, related aircraft and method are provided. The system includes a rotary controller configured to control a target on the display device; a target manager, controlled by the rotary controller for moving the target on the display device during the rotation of the rotary controller and/or for interacting with a field targeted by the target during the rotation of the rotary controller; a haptic feedback generator on the rotary controller during its rotation. The haptic feedback generator is configured to generate at least two distinct haptic profiles on the rotary controller depending on distinct system states and/or distinct man-machine interface states of the aircraft.

First claim

What is claimed is:

1. An interface system between a user and a display of an aircraft, comprising:
a rotary controller configured to control a target on the display;
a target manager, controlled by the rotary controller for moving the target on the display during the rotation of the rotary controller and/or for interacting with a field targeted by the target during the rotation of the rotary controller;
a haptic feedback generator on the rotary controller during its rotation, the haptic feedback generator being configured to generate at least two distinct haptic profiles on the rotary controller depending on distinct system states and/or distinct man-machine interface states of the aircraft,
wherein the haptic feedback generator is configured to generate the at least two distinct haptic profiles on the rotary controller during the interaction with a same field targeted by the target, depending on the system states and/or man-machine interface states of the aircraft.

2. The system according to claim 1 , wherein the haptic feedback generator is a torque generator, configured to apply on the rotary controller a torque according to the haptic profile generated during the rotation of the rotary controller by the user.

3. The system according to claim 1 , wherein the haptic feedback generator is configured to generate distinct haptic profiles on the rotary controller during the control of two distinct targeted fields, depending on the system states and/or man-machine interface states of the aircraft.

4. The system according to claim 1 , wherein the distinct man-machine interface states include distinct input interface states which comprise distinct speeds of rotation of the rotary controller, the haptic feedback generator being configured to generate a first haptic profile at a first speed of rotation of the rotary controller and a second haptic profile distinct from the first haptic profile at a second speed of rotation of the rotary controller.

5. The system according to claim 1 , wherein the distinct man-machine interface states include distinct graphic interface states which comprise positions of the target on successive lists of fields on the display screen, the haptic feedback generator being configured to generate a first haptic profile when the target targets a first list of fields and a second haptic profile distinct from the first haptic profile when the target targets a second list of fields.

6. The system according to claim 1 , wherein the distinct system states comprise distinct flight phases of the aircraft, the haptic feedback generator being configured to generate a first haptic profile during a first flight phase of the aircraft, and to generate a second haptic profile during a second flight phase of the aircraft.

7. The system according to claim 6 , wherein the first flight phase is a low altitude transition, the second flight phase being a cruising of the aircraft.

8. The system according to claim 7 , wherein the low altitude transition is an ascent or an approach of the aircraft.

9. The system according to claim 1 , wherein the distinct system states comprise a normal operating state of an airplane system and/or of the aircraft and a degraded operating state of an airplane system and/or of the aircraft, the haptic feedback generator being configured to generate a first haptic profile in the normal operating state and being configured to generate a second haptic profile in the degraded operating state.

10. The system according to claim 1 , wherein the haptic profile comprises at least one wall defining a limit of a preferred domain of use of the rotary controller.

11. The system according to claim 1 , wherein each haptic profile comprises at least one notch, a first haptic profile comprising at least one first notch distinct from at least one second notch of a second haptic profile.

12. The system according to claim 11 , wherein the first haptic profile comprises a first series of successive notches, the second haptic profile comprising a second series of successive notches of profiles and/or intensity distinct from the notches of the first series.

13. A control set of an aircraft, including:
a display, positioned in the cockpit of the aircraft;
the interface system according to claim 1 ;
an avionics unit configured to interact with airplane systems, the interface system being configured to communicate with said avionic unit for determining the current system and/or man-machine interface states of the aircraft.

14. An interaction method between a user and a display of an aircraft, comprising the following steps:
providing the interface system according to claim 1 ;
in a first system and/or man-machine interface state of the aircraft, driving into rotation of the rotary controller by a user, the haptic feedback generator generating a first haptic profile on the rotary controller; and
in a second system and/or man-machine interface state of the aircraft, driving into rotation of the rotary controller by a user, the haptic feedback generator generating a second haptic profile on the rotary controller.

15. The method according to claim 14 , wherein the steps of driving into rotation of the rotary controller by a user in the first system and/or man-machine interface state of the aircraft and in the second system and/or man-machine interface state of the aircraft cause interaction of the target with the same field on the display.

16. The system according to claim 1 , wherein the field is an input field of a set value of a flight parameter, a value of the set value being modified by rotating the rotary member;
the distinct man-machine interface states including distinct input interface states which comprise distinct speeds of rotation of the rotary controller, the distinct speeds of rotation being at least comprised in a first range of speeds of rotation greater than a predetermined speed of rotation, or in a second range of speeds of rotation less than a predetermined speed of rotation;
the set value being modified with a first increment when the speed of rotation of the rotary controller is comprised in the first range, or with a second increment when the speed of rotation of the rotary controller is comprised in the second range;
the haptic feedback generator being configured to generate a first haptic profile at a speed of rotation of the rotary controller comprised in the first range, and a second haptic profile distinct from the first haptic profile at a speed of rotation of the rotary controller comprised in the second range.

17. The system according to claim 1 , wherein the field is an input field of a set value of a flight parameter, a value of the set value being modified by rotating the rotary member;
the distinct man-machine interface states of the aircraft comprising an indication of the type of input mode and/or of scale selected into which the set value has to be inputted;
the haptic feedback generator being configured to generate a first haptic profile when the indication corresponds to a first type of input mode and/or of scale, and a second haptic profile distinct from the first haptic profile when the indication corresponds to a second type of input mode and/or of scale.

18. The system according to claim 17 , wherein the first and second input modes and/or scales are distinct units of the flight parameter.

19. An interface system between a user and a display of an aircraft, comprising:
a rotary controller configured to control a target on the display;
a target manager, controlled by the rotary controll
