Thus the learning device of a driving assistance function of a vehicle according to the invention comprises receiving from a location system, the current localized position of the vehicle. The device also receives, via the man-machine interface, the first command triggered by the user. In addition, the device activates or disables a driving assistance if the first command has already been triggered during a given number of vehicle trips each time in an environment or perimeter set around the current localized location. Advantageously, this device can learn and simplify the use of the vehicle by automating repetitive routine functions, depending on the location. This simplifies the driving of the vehicle and increases its comfort. According to one feature of the device, the assistance is to realize the device to automatically trigger the first command during the next path or to allow the user to trigger the first command by the man-machine interface as soon as the vehicle enters the the perimeter set around the location position. Advantageously, it is possible to automate for the future operations or manipulations that the user has repeated during previous trips in a given perimeter. Advantageously, the use will be made automatically in the future or will be offered to the user. According to another development, the first command initiated by the user cancels a second command automatically triggered by the vehicle, the assistance consisting in making the device to not automatically trigger the second command on the next trip if the vehicle is at the same time. inside the perimeter set around the localized position. In this case, the driving assistance realizes the device so that it does not automatically trigger the second command during the next journey when the vehicle enters the perimeter

3 fixed around the localized position. Advantageously, the device can then unlearn or neutralize automatic functions of the vehicle. This can also increase the comfort of use of the vehicle.

According to a development, the device is characterized in that it is designed to propose to the user, during the following path, the triggering of the second command via the man-machine interface as soon as the vehicle enters the the perimeter set around the localized position. Advantageously, the user will then be able to execute the command which will no longer be triggered automatically. According to another development, the invention relates to a device characterized in that it is realized to recognize the first command only if it has already been triggered for a fixed number of vehicle trips, - if a destination used in previous cases by the vehicle navigation system is consistent with the destination currently used by the navigation system, - and / or a distance determined in previous cases with respect to the destination of the vehicle differs from the actual distance to the destination, only from a first fixed distance, - and / or the direction of movement of the vehicle in previous cases corresponds to the current direction of movement of the vehicle, - and / or the location of the vehicle in previous cases corresponds to the location for the current journey, - and / or the time in earlier cases differs from the current time only by a fixed duration, - and / or the time In the earlier cases, the outside temperature differs from the current outside temperature only by a fixed temperature difference. Thus, advantageously, the learning function of the device can recognize and take into account not only the localized position of the vehicle but also the destination, the distance to the destination, the direction of travel.

4 placement, location, time and / or outside temperature. This allows for more complex patterns and correlations between external circumstances and user-initiated control indications, to recognize and account for them, thereby increasing the user comfort of the vehicle. The invention also relates to a method of learning a function of a driving assistance in a motor vehicle, comprising the following steps: - reception of the location position of a vehicle location system, - reception of a control by a man-machine interface of the vehicle, and - activation or deactivation of a driving assistance if the control indication has been received previously in a fixed number of cases within a perimeter fixed around the position of the vehicle.

Advantageously, the user of the vehicle is thus discharged from routine functions, tedious. According to an alternative embodiment, the con-duite assistance for the user is proposed by the man-machine interface to trigger the first command as soon as the vehicle enters the perimeter fixed around the localized position. According to another characteristic of the method, the first command neutralizes a second command triggered automatically previously by the vehicle, the driving assistance does not automatically trigger the second command during the next course if the vehicle is in the perimeter set around. the localized position. This advantageously allows to cut the automatic functions of the vehicle if they oppose the wish of the driver. Drawings The present invention will be described in more detail below with the aid of exemplary embodiments shown in the accompanying drawings in which the same references will be used to designate the same elements or the elements of the same function. Thus: - Figure 1 is a schematic view of different components of a motor vehicle, - Figure 2 is a schematic view of a vehicle in a traffic situation. DESCRIPTION OF EMBODIMENTS OF THE INVENTION FIG. 1 shows various components of a motor vehicle 200 according to a simplified representation in the form of a block diagram. The motor vehicle 200 comprises a device 100. This device 100 is connected to a location system 110, to a man-machine interface 120, to a data memory 130 and to a control device 140. The location system 110 determines the position of the vehicle 200. The locating system 110 may include for this purpose for example a GPS receiver for satellite assisted locating of the vehicle 200. The rental system 110 may be part of a navigation system integrated in the vehicle 200. The man-machine interface 120 enables the user of the vehicle 200 to cooperate with different components of the vehicle 200. The man-machine interface 120 may comprise control elements such as keys, switches, grout strips. - health. The human-machine interface 120 may also include a voice recognition system or gesture recognition. In addition, the man-machine interface 120 may comprise optical display devices such as image screens, control lamps and arrows as well as acoustic emission devices such as

6 speakers. The human-machine interface 120 may be integrated in the vehicle dashboard 200. The data memory 130 is preferably a nonvolatile data memory. The data memory 130 can receive at the factory data such as, for example, digital road maps. The data memory 130 can also be used to record and read back data produced during the operation of the vehicle 200. The data memory 130 is for example embodied in the form of a flash memory.

The control apparatus 140 serves to control various components of the vehicle 200. The control apparatus 140 may be the engine management apparatus for controlling the internal combustion engine of the vehicle. The control apparatus 140 may also control other components of the vehicle such as for example an air conditioning system, a generator or a leisure equipment. The control device 140 may for example be in the form of a microcontroller or a microcomputer. There may be more than one controller 140 each connected to the device 100. The device 100 may also be implemented as a microcontroller or microcomputer. The device 100 can be integrated in the positioning system 110, in a navigation system or in the control apparatus 140. The device 100 is connected to other components of the vehicle 200 not shown in FIG. 1. For example, the device 100 is connected to sensors which determine the speed of the vehicle, the direction of movement, the clock time and the outside temperature. The man-machine interface 120 allows the user of the vehicle 200 to trigger control indications to adjust to different components of the motor vehicle 200. For example, the user of the vehicle 200 can switch over the man-machine interface 120 to switch off the lighting of the vehicle 200 or connect it. The user of the vehicle 200 can also connect or cut the air conditioning system of the vehicle 200 via the man-machine interface 120 or else change the set temperature of the vehicle 200.

7 the air conditioning system or operate the air conditioning system in air circulation mode. The control of the vehicle 200 may, however, appear to be complicated and uncomfortable for the user of the vehicle 200 if the user must regularly ask for repeated changes in the setting of the vehicle 200. For example, it may seem tedious for the user of the vehicle 200 of modify the air circulation mode of the air conditioning system whenever the vehicle 200 arrives in a parking lot and it must activate the installation manually. If necessary, it may happen that because of this, the driver of the vehicle 200 rarely or never uses certain functions of the vehicle 200. To relieve the user of the obligation to repeat too frequently certain order indications which are repeated, the vehicle 200 has automatic control aids. Such control or assistance aids are intended to automatically detect the probability of certain requests from the user and to automatically ensure these commands without the intervention of the user of the vehicle 200. For example the vehicle 200 comprises a sensor 20 ambient light that detects twilight or entering a tunnel or garage and automatically turns on the vehicle lighting. The disadvantage of this predefined assistance fixed by the manufacturer lies in its lack of flexibility. Many routine functions, tedious to the user, depend on the individual use of the vehicle 200 by a particular user and can not be provided at the factory. Under the same conditions, automatic assistance provided at the factory may be contrary to the individual wish of the user of the vehicle 200 and may complicate the use of the vehicle. In addition, it is possible for the user of the vehicle 200 to wish to react differently to comparable situations, depending on the location of the vehicle 200. For example, the user of the vehicle entering a garage he do not know, may wish to automatically connect the vehicle lighting while at the entrance to the garage of the home, he may consider this operation as unnecessary. That is why it is desirable to equip the vehicle 200 with a

8 assistance with learning adapting to the individual requirements of the user. In addition, the assistance must take into account the possible dependence of the locality for the wishes of the user. The device 100 is designed to execute a method of learning such a helper function. With the help of Figure 2, will be described below two embodiments of the method of learning a function of assistance. Figure 2 shows a schematic view of the vehicle 200 in a traffic situation. The user of the vehicle 200 arrives with his vehicle 200 in a public garage 210. To avoid breathing exhaust fumes harmful to his health, the user triggers at the instant shown, an indication of command transmitted by the human-machine interface 120 for switching the air conditioning system of the vehicle 200 on the internal air circulation mode. The device 100 determines with the aid of the location system 110 that the vehicle 200 is in the first location position 220. Using the data sets stored in the data memory 130, the device 100 further recognizes that the user of the vehicle has already initiated the same command previously, already in a second place 221, in a third place 222 and in a fourth place 223. The second place 221, the third place 222 and the fourth place 223 are located in a perimeter set 240 around the first current position 220 of the vehicle 200. The user of the vehicle 200 has thus triggered for the fourth time the switching command of the air conditioning system to switch to circulation mode inside. the fixed perimeter 240 around the first location position 220. The fixed perimeter 240 may have for example a radius of 100 meters. But he may also consider a larger or smaller radius. The size of the perimeter 240 may also be measured according to the speed of the vehicle 200. For example, if the environment 240 has a diameter that the vehicle travels in 10 seconds at its current speed. In the example presented above, the device 100 unlocks the reaction described below as soon as the same command has been triggered four times within the fixed perimeter 240. But it is

It is also possible to carry out the expected reaction, consecutive, from before or only after the increased number of repetitions of the identical command indication. According to preferential developments, the dis-positive 100 makes it possible to take into account the period within which the command has repeated the fixed number of times. The device 100 may take into account if the command indication has not been triggered during intermediate courses within the envelope perimeter 240. After recognition by the device that the user of the vehicle 200 wished to trigger the indication control device for switching the air conditioning system, regularly at the first position 220, the device 100 records a corresponding information in the data memory 130. When the user of the vehicle 200 orders the next time the direction of the public parking 210 and approaches the fixed perimeter 240 around the first position 220, then the device 100 can automatically trigger the command to switch the air conditioning system to the internal circulation mode. The device 100 has thus learned the desired behavior of the user of the vehicle 200 and facilitated the use of the vehicle 200 for the user. Alternatively, the device 100, at the next entry of the vehicle 200 in the public parking 210, can trigger the control indication to switch the air conditioning system, not automatically to the user of the vehicle 200 by the human-machine interface 120 to propose to him to trigger the indication of command with however its confirmation. At this moment, it is sufficient for the user of the vehicle 200 to actuate a control element to confirm the command indication. This on the one hand facilitates the use for the driver of the vehicle 200 and on the other hand it has control of the control indications that have been triggered. But it is also possible to perform the learning operation of the device 100 in two steps, namely in a first learning step, it develops a control indication recognized as being repeated regularly for the user by the human-machine interface 120 to be operated. If the user of the vehicle 200 has actuated the proposed trigger of the command indication, a fixed number of times, there is a second learning step of the device 100 which makes

10 that the command indication will be triggered in the future, automatically, without the intervention of the user. In the example described, the device 100 considers that the switching command of the air-conditioning system has been repeated repeatedly if it has been triggered several times within the fixed perimeter 240 around the first localized position 220 According to a development, the device 100 can take into account other parameters in its evaluation. For example, the device 100 can compare the current overshoot direction 230 of the vehicle 200 with directions of movement of the vehicle 200 in earlier cases for which control has been initiated. Alternatively, the device 100 may take into account a predicted destination transmitted by the navigation system for the vehicle 200, the distance from the intended destination of the vehicle 200, a starting position for the present path of the vehicle 200, the time and the outside temperature. Orders will only be considered multiple times if one or more of these parameters existed during each triggering of the order within fixed limits and had the same value.

According to a second embodiment of the invention, the device 100 cuts the automatic assistance if it opposes the wish of the driver. For example, the vehicle 200 is constructed so that at the entrance to the public garage 210, it detects a reduced ambient brightness and automatically connects the lighting of the vehicle 200.

But it is possible that the user of the vehicle 200 considers the connection of the lighting as unnecessary because the journey to go in the public parking 210 is very short and the lighting in the parking lot 210 is sufficient or that the user is familiar with the journey in the parking 210. In this case, it is possible for the user of the vehicle 200 to react to the automatic connection of the vehicle lighting by a command to immediately cut the vehicle lighting. But these operations reduce the life of the lighting means of the vehicle. If the device 100 records that the user of the vehicle 200 has triggered a fixed number of times (for example four times), the

11 control of cut-off of the vehicle lighting in the perimeter set 240 around the first current localized position 220 of the vehicle 200, and that each control of the lighting of the vehicle lighting was followed by the automatic connection of the lighting , this means that the device 200 is made to neutralize the automatic connection of the vehicle lighting in a fixed area 240 around the localized position 220, in the future. When the user of the vehicle 200 arrives the next time in the public garage 210, the lighting of his vehicle 200 will not be connected automatically. Alternatively, the connection of the vehicle illumination may be offered to the user by the man-machine interface 120 to be confirmed. This makes the use of the vehicle 200 more comfortable. In addition, the lighting of the vehicle 200 is saved by avoiding an unnecessary start / stop. The invention can also be transposed to other commands that the user of the vehicle 200 triggers to control various equipment of the vehicle 200.20 NOMENCLATURE
