    专利说明:

    [0001] The invention relates to a human-machine interface for a motor vehicle for controlling the taking into account of at least one function of a motor vehicle.
    [0002] More and more functions capable of controlling equipment placed in the passenger compartment of motor vehicles can be controlled by non-contact commands, for example by detecting a particular gesture made by the driver or a passenger. However, it is difficult for the user wishing to activate a function by a contactless control to know if this function has been correctly taken into account by the detection system. There are visual feedback systems of the order taking, for example by means of the display of an indication of the order taking. However, this type of return of order takes the user generally to leave the road of the eyes to see if his order has been taken into account. This can be particularly dangerous especially if the user is the driver of the vehicle. There are also auditory feedback systems of the order taking, for example by means of the emission of a particular sound to confirm the taking into account of the command. This type of return allows the user to remain focused on the road, however, depending on the sound environment in the vehicle, these types of feedback may be insufficient. Thus, there is a need to provide an assembly for controlling the taking into account of at least one function of a motor vehicle in a reliable and safe manner. For this purpose, according to a first aspect, the subject of the invention is a man-machine interface for a motor vehicle comprising: a control device comprising at least one sensor configured to detect a contactless command from a user, and a haptic feedback device for controlling the taking into account of said command, remarkable in that - the haptic feedback device cooperates with a device of the passenger compartment of the motor vehicle, said equipment being distinct from the control device, - said equipment is intended to come into contact with a part of the body of the user in order to perceive the haptic feedback signal.
    [0003] Thanks to the invention, the user can reliably and safely obtain a return on the consideration of its control of a function in the passenger compartment of the motor vehicle. Indeed, the control signal perceptible by the body of said user allows the latter to perceive the signal and whatever the sound environment and without having to look away from the road.
    [0004] The human-machine interface according to the invention may also comprise one or more of the following characteristics, considered individually or in any technically possible combination: the return device comprises a vibrating device configured to communicate one or more vibrations to the equipment associated with the return device, the intensity of the vibrations being sufficient to be felt by said part of the body of the user; and / or the sensor comprises an infrared system and / or a capacitive system and / or a camera; and / or the control device is able to cancel or trigger a controlled function by transmitting an activation signal; and / or the human-machine interface is configured so that the time separating the activation of the control device and the transmission of the return signal by the return device is less than or equal to 100 ms, in particular less than or equal to 90ms; and / or the man-machine interface further comprises a programming device configured for the user to program the intensity and the duration of the return signal emitted by the return device and the duration separating the command and the transmission. return signal by the return device; and / or - the return device is associated with a hand rest of the motor vehicle; and or. - The return device is associated with the steering wheel of the motor vehicle; and / or - the return device is associated with the driver's seat of the motor vehicle; and / or - the return device is associated with the armrest of the motor vehicle. Another object of the invention consists in a method for manufacturing a man-machine interface for controlling the taking into account of the control by a user of at least one function of a motor vehicle, said method comprising steps for provide a control device for said at least one function and provide a return device capable of sending a perceptible feedback signal by a part of the user's body, associating the return device with a device of the cabin of the motor vehicle so that the return signal is noticeable by the body part of the user through said equipment of the passenger compartment. The invention also relates to a method for controlling the taking into account of the control by a user of at least one function of a motor vehicle, in which an assembly as described above is implemented, in particular in one any combination.
    [0005] More particularly, the invention also relates to a method for confirming the taking into account of the control by a user of at least one function of a motor vehicle, said method comprising at least one sending step, via a return device associated with a cabin equipment, a return signal perceptible by a part of the user's body following the user's command of said function by means of a control device , said part of the body of the user being in contact with said equipment of the passenger compartment. The invention will be better understood on reading the following description given by way of nonlimiting example of implementation thereof, and on examining the appended drawings in which: FIG. 1 illustrates an interface human-machine according to a first embodiment of the invention, wherein the return device is associated with the steering wheel of a motor vehicle; - Figure 2 illustrates a human-machine interface according to a second embodiment of the invention, wherein the return device is associated with the armrest of a motor vehicle. FIG. 3 illustrates a human-machine interface according to a third embodiment of the invention, in which the return device is associated with a pommel of a motor vehicle. - Figure 4 illustrates a human-machine interface according to a fourth embodiment of the invention, wherein the return device is associated with the driver's seat of a motor vehicle. Referring to FIG. 1, the man-machine interface according to the invention makes it possible to take into account commands from at least one function of a motor vehicle such as a car. The human-machine interface comprises a control device 1 and a return device 2. In particular, the control device is configured to transmit an activation signal so as to trigger or cancel said function. The controller 1 is of the type generally implemented in motor vehicles. In some cases, the control device 1 is adapted for non-contact control. Thus, it may include a sensor 12 capable of detecting and recognizing the user's gestures. For example, this type of sensor may comprise an infrared and / or capacitive sensor, and / or a camera or any other sensor of this type known to those skilled in the art. The control device 1 is configured to control at least one function of a motor vehicle. The functions that can be implemented in the context of the invention include functions relating to the car radio and / or the navigation system and / or the heating and / or air conditioning and / or seat configuration and / or the cockpit 20 and / or the door and / or the window and / or the on-board computer. As illustrated in FIG. 1, the control device 1 may comprise a display device 11 such as a screen serving as an interface and allowing the user to view the commands and their taking into account by the human interface. -machine according to the invention. The display device 11 enables the user to visualize the effectiveness of said function of the motor vehicle, preferably outside the driving periods. Indeed, during driving periods, it is preferable to use a non-visual feedback signal confirming the consideration of the command. In particular, a signal by a contact link with the user is preferred, for example, when the sound environment does not lend itself to an auditory feedback signal. In addition, in the case of a contactless control such as gesture sensors, a vibratory feedback via a control device such as a joystick is not operative given the absence of contact. Thus, the inventors have found that a return via a cabin equipment is of interest for safety. The return device 2 of the man-machine interface according to the invention is configured to send the user a return signal perceptible by the latter, in particular in the form of a vibratory signal, via a device 3 of the cockpit. The equipment 3 of the passenger compartment is preferably an element of the passenger compartment which is frequently in contact with a part of the body of the user. This equipment transmits a feedback signal to the user via this contact. Of course, an equipment is chosen according to its ability to significantly transmit said return signal. In particular, a transmission by rigid equipment such as the steering wheel easily to transmit a vibrating feedback signal. Alternatively, less rigidity can be compensated for by greater vibration intensity. In the embodiment of Figure 1, the equipment 3 of the cabin is a steering wheel. The return device 2 is for example connected directly to the equipment 3 of the passenger compartment so as to transmit the noticeable feedback signal. According to a preferred variant, the return device 2 comprises a vibrating device capable of communicating vibrations to at least one equipment of the passenger compartment. Alternatively, it is possible to provide an intermediate means receiving a signal from the return device and able to transmit a confirmation signal to the equipment 3 of the cabin which in response will generate the return signal. The return device 2 is a module comprising electronic components able to receive and process information from the control device 1. Advantageously, the choice of the steering wheel as equipment 3 transmitting the return signal, allows the transmission of information to the user through his second hand 5, placed on it. In practice, the perception by the hands is significantly sensitive compared to the rest of the body of the user. In addition, the hand is generally not covered with clothing in a driving situation. Finally, the steering wheel is the element of the cabin most often in contact with the hands of the driver. In practice, the signal will be perceived by the user when its intensity is greater than a predetermined threshold. This predetermined threshold of intensity is a function, inter alia, of the equipment used to transmit the vibrations and of the part of the body of the user in contact with the latter. Advantageously, the return device 2 comprises a vibrating device 21 configured to communicate one or more vibrations to the equipment of the passenger compartment. One can provide a vibrating device 21 integrated into a mechanical system integral with the steering wheel. For example, this vibrating device 21 can be integrated with a power steering system or other force feedback systems. Alternatively, the vibrating device 21 can also be integrated in the steering wheel. According to another possibility, the vibrating device 21 is integrated with a steering wheel control system incorporating a haptic feedback device. In the latter case, it is preferable to implement a more powerful signal to improve the transmission of the center to the periphery of the steering wheel. Alternatively one can also provide the use of an already existing vibrating device. For example, a power steering system, a force feedback system or a haptic steering wheel control system.
    [0006] According to one embodiment, the man-machine interface according to the invention is configured so that the time separating activation of the control device and transmission of the return signal by the return device is less than or equal to 100. ms, more particularly less than or equal to 90 ms. Advantageously, a delay less than or equal to 100 ms between the activation and the emission of the return signal enables the user to clearly identify the return as corresponding to the activation of the command. It is also possible to provide the possibility of configuring the intensity and / or the duration of the return signal and / or the time between the command and the transmission of the return signal. An interface of a known type can be implemented for this purpose. These aspects make it possible to configure the human-machine interface according to the invention according to the preferences of a given user. Similarly, it can also be provided that the duration of the vibrations can be configured by the user. In use, when the user actuates the control device 1 by means of his first hand 4. The control device identifies (a) the gestures of the user and transmits (b) a confirmation signal to the return device 2. Then, the return device 2 transmits (c) a vibration signal to a device 3 of the passenger compartment, here a steering wheel. Thus, the equipment 3 of the passenger vibrates (d) perceptibly by a portion of the body of the user, through said equipment, here the steering wheel in contact with the second hand 5 of the user. Thus, in general, the method according to a variant of the invention comprises implementing the steps (a) to (d) described above.
    [0007] The control device 1 cooperates with the return device 2, in particular by means of a signal transmission from the control device 1 to the return device 2, so as to communicate the confirmations of the taking into account of the commands. This cooperation is shown schematically by the reference arrow (b) in the figures. Referring to FIG. 2, the man-machine interface according to a second embodiment is similar to that described above with equipment 3 transmitting a noticeable feedback signal, which is an armrest, for example a central armrest. The physical connection between the user's body and the armrest may be the elbow or forearm. An armrest, as equipment 3 of the passenger compartment, is comfortable, and the position of the natural user, the elbow and / or the forearm being at rest on the armrest. In addition, the choice of an armrest as equipment 3 makes it possible to make the human-machine interface according to the invention usable by a passenger. In addition, the armrest has a rigidity allowing for the transmission of a vibrating feedback signal. In use, the user controls a function, for example by a gesture of the hand 4 via an interface of a display device 11 such as a remote screen, a multifunctional tablet or joystick combined with a control means. particularly by gestures. The changes of function or validations are confirmed to the driver by a perceptible signal, preferably vibratory. This signal can be programmable or unique transmitted via the elbow and / or the forearm of the user.
    [0008] Of course, this embodiment is not limited to the central armrest. For example, it can be implemented on the left side, in particular for door or air conditioning control commands. Referring to Figure 3, the human-machine interface according to a third embodiment is similar to that described above with a device 3 of the cabin 30 transmitting a noticeable feedback signal, which is a knob. This set can be implemented in the same way as a set according to the second variant with the only difference that it is a knob as equipment 3 of the cabin. This variant is also comfortable, it being understood that the entire arm is generally at rest when the first hand of the user is on the pommel. A hand rest (or "pommel") is a rigid part of the cabin where you put the wrist to have a fulcrum to control a touchpad or a joystick. Such a hand rest is usually located at the center console located between the two front seats of the vehicle. Referring to Figure 4, the human-machine interface according to a fourth embodiment is similar to those described above with a cockpit equipment 3 transmitting a noticeable feedback signal, which is a seat. A seat, has the advantage of being in constant contact with the body of the user that it is driver or passenger. In addition, this embodiment does not require a particular position of either hand of the user. Taking into account the flexibility of the seat, the intensity of the vibrations must be significantly important to be perceived by the user. In this embodiment, a vibrating device 21 or an actuator may be integrated into the seat, for example an actuator similar to those used in over-line warning systems on the road. The return device 2 may be associated with the driver's seat and / or the seat of a passenger. Thus, a passenger making orders can also be informed by the return device. The actuators can be provided in the seat and / or in the backrest. Actuators may also be provided in the headrest. The file has the advantage of a contact usually more frequent with the user compared to the headrest. The same is true of the seat in relation to the file. Of course, the invention is not limited to the described embodiments and extends to other variants within the scope of the claims. Herewith the word "comprising" does not exclude other elements, and the indefinite article "a" or "an" does not exclude a plurality. The mere fact that the various features are cited together in different dependent claims does not indicate that the combination of these features can not be advantageously used. Any reference sign in the claims should not be interpreted as limiting the scope of the invention.
