Definitions
- Communication system configured to communicate with the vehicles of a set of vehicles
- the invention relates to the field of applications on board motor vehicles. It relates more particularly to a device and a method for managing such applications.
- the number of applications on board motor vehicles is constantly increasing, whether they are applications intended to manage and/or control the operation of the vehicle, such as, for example, applications for launching the on-board computer or communication with remote servers, whether these are applications intended to manage the active safety of the vehicle such as, for example, braking control applications, whether these are applications guidance, for example satellite guidance, or whether these are applications relating to the comfort of the occupants of the vehicle, such as, for example, applications allowing personalization of the driver's environment by adjustment and/or seat heating.
- applications intended to manage and/or control the operation of the vehicle such as, for example, applications for launching the on-board computer or communication with remote servers, whether these are applications intended to manage the active safety of the vehicle such as, for example, braking control applications, whether these are applications guidance, for example satellite guidance, or whether these are applications relating to the comfort of the occupants of the vehicle, such as, for example, applications allowing personalization of the driver's environment by adjustment and/or seat heating.
- the technical problem to which the present invention proposes to provide a solution is that of the management of such malfunctions.
- a communication system configured to communicate with the vehicles of a set of motor vehicles, characterized in that it comprises:
- an identification and classification unit among the information transmitted by a plurality of vehicles of the set of vehicles, of signatures representing Sentiments of malfunctions of on-board applications on vehicles,
- - a unit configured to compare, for one of the applications for which at least one signature has been identified and classified, a parameter of appearance of signatures representative of malfunctions of this application with a first predetermined threshold, and/or to compare a parameter of stability of this application with a second predetermined threshold,
- a communication device configured to transmit to at least one vehicle of the set of vehicles an order to deactivate an application according to the result of the comparison(s) made by the unit.
- the vehicles of the set of vehicles can be identical to each other or different from each other.
- the communication system according to the invention is not physically placed on any of the vehicles of the set of vehicles, but that it is located at a distance from the latter, with which it is configured to communicate.
- on-board application designates here an application intended to operate on all the vehicles of the set of vehicles, whether these are identical to each other or not, as soon as these vehicles are running, whether they are moving or not.
- on-board applications may include applications relating to vehicle safety such as, for example, trajectory management applications or braking management applications, applications relating to the ability of the vehicle to communicate remotely, for example with the communication system according to the invention, or applications intended to improve the comfort of the occupants of the vehicle such as heating or air conditioning management applications, geolocation and/or guidance applications . It is thus possible to define different types of applications according to the type of purpose of these.
- the transmission of information between the vehicles and the communication system is carried out via the Internet or via a communication protocol specific to the vehicle, for example via a cellular network.
- each malfunction of an application generates the creation of specific information, representative of the malfunction that has occurred, intended for the recording and storage unit of the system according to the invention.
- the specific information also referred to as a signature in the following, takes the form of at least one line of source code and it comprises, on the one hand, data relating to the identification of the application having presented a malfunction and, on the other hand, data relating to the nature of the malfunction that occurred.
- the data relating to the nature of the malfunction can be, for example, start-up information impossible, execution error information, communication error information for one or more data, etc.
- the specific information, or signature may contain geolocation data, to facilitate the analysis of the malfunction, if necessary.
- the identification and classification unit which recovers all of the information stored by the recording and storage unit, is configured to read the lines of code for each of the information sent to it and it is configured to detect a specific form of a line of code, for example by the presence of a specific marking at the beginning or at the end of the line without this being limiting of the invention, and to classify it as signatures representative of a specific malfunction for a given application.
- the invention therefore proposes to identify and classify the signatures of the malfunctions of the on-board applications on all the vehicles of the previously defined set of vehicles. According to various examples, these signatures can be classified by application, by type of application (applications relating to vehicle safety, applications relating to occupant comfort, etc.), or by nature of malfunction.
- the appearance parameter is representative of a number of occurrences of the previously defined signatures.
- a threshold value here a first threshold, makes it possible to trigger preventive actions on the fleet of vehicles associated with this communication system as soon as the appearance parameter has a particular value with respect to an alert threshold.
- the appearance parameter is a value representative of a number of occurrences of all the signatures representative of a malfunction of the same application.
- the appearance parameter is a value representative of a number of occurrences of a defined signature; in other words, this appearance parameter is representative of a number of occurrences of a specific malfunction of a given application.
- the appearance parameter is calculated by multiplying the number of occurrences of a signature defined by the number of vehicles concerned by the appearance of this signature, or else by multiplying the number of occurrences of the set signatures representative of a malfunction of the same application by the number of vehicles concerned by the appearance of these signatures.
- the first threshold has an identical value for all the signatures of all the applications.
- the first threshold has a value defined for each signature of each application, the value of the first threshold being able to vary from one signature to another, in particular according to the degree of criticality of the corresponding application.
- the first threshold has a value defined for each type of application, that is to say that a first threshold can have an equal value for all the signatures of the malfunctions of all the applications of a first type given, and that another first threshold, distinct, can have a distinct value and which applies to all the signatures of an application of another type of application.
- the stability parameter is representative of a duration between two successive occurrences of a signature as previously defined.
- a threshold value here a second threshold
- the second threshold has an identical value for all the signatures of all the applications
- the second threshold has a value defined for each signature of each application, the value of the second threshold being able to vary from one signature to another, in particular according to the degree of criticality of the corresponding application,
- the second threshold has a value defined specifically for each type of application, that is to say that a second threshold can have a value which applies to all the signatures of the malfunctions of all the applications of a given first type, and that another second threshold can present a distinct value and which applies to all the signatures of an application of another type of application.
- Deactivation here is to be understood as a temporary blocking of the operation of an application. According to the invention, such deactivation is performed when the vehicle is started, before the application starts.
- the invention provides that such deactivation can in particular be carried out for at least one vehicle of the set of vehicles, and in a particular case, for all the vehicles of the set of vehicles, that the application concerned presented or not one or more malfunctions.
- the invention provides that the deactivation order is transmitted to all the vehicles of the set of vehicles, including those on which the application has not presented any malfunction.
- such deactivation is temporary, until the resolution of the malfunction(s) having led to the deactivation of the application in question. According to various examples, this resolution can occur spontaneously during a subsequent start-up of the vehicle or by the transmission to the vehicles, by the communication system according to the invention, of an update of the application concerned.
- the invention therefore makes it possible to selectively deactivate, and before they start, on all the vehicles of the set of vehicles, applications which have previously had too many malfunctions or which have presented one or more malfunctions considered too close together.
- the invention allows preventive deactivation of applications which present, with regard to their prior operation and prior malfunctions, a risk of malfunction deemed too great.
- This makes it possible, on the one hand, to avoid the occurrence of more extensive malfunctions due to a form of cascading effect, and, on the other hand, to avoid any degradation of the image of the vehicle and its operation with regard to the user who could be discouraged by repetitive malfunctions and turn to a vehicle from another manufacturer.
- this makes it possible to reduce the energy consumption of the vehicle due to the mobilization of the electronic systems by excessive or too frequent repetition of the aforementioned malfunctions.
- the deactivation of an application on the vehicles of the set of vehicles is effective when the appearance parameter has a value greater than the corresponding first threshold value and/or when the stability parameter has a value lower than the corresponding second threshold value.
- the deactivation of an application may be effective when these two conditions are met, namely excessive occurrence of the malfunction which suggests that this malfunction may spread to the entire fleet of vehicles, and excessive occurrence a malfunction which suggests that the on-board computer of the vehicle concerned tries to restart the faulty application too often, which may penalize the operation of other non-faulty applications.
- the deactivation of an application via a deactivation order transmitted by the communication device, may be, whether systematically or solely depending on the level of criticality of the application in question, subject to or conditional on confirmation of the user of the vehicle on which the application must be deactivated.
- the identification and classification unit is configured to attribute to each application on board the vehicles of the set of vehicles a label representative of a criticality of the application considered.
- the communication system comprises a comparison unit which is configured to compare the signature appearance parameter to the first threshold and/or the stability parameter to the second threshold only for applications to which a certain type of label representative of a criticality of the application considered is assigned.
- calculation unit the configuration unit and the comparison unit are the same electronic entity which is configured to perform each of these functions.
- the values associated with the first threshold and/or with the second threshold are functions of the label representing a criticality of the application considered.
- the subject of the invention is a communication method between a communication system as just described and the vehicles of a set of motor vehicles, characterized in that it comprises :
- the step of analyzing the signatures representative of malfunctions, or signatures as previously defined includes an operation of classifying this information, for example by type of malfunction and/or by application.
- the step of analyzing the signatures representative of malfunctions includes an operation for counting the number of occurrences of the signatures.
- the counting operation is performed for each signature received by the communication system, that is to say for each type of malfunction of each application.
- the counting operation is performed for all the signatures associated with each application, that is to say for all the malfunctions of a given application, without distinction of the type of malfunction that has occurred. This counting operation allows in particular the calculation of an appearance parameter.
- the step of analyzing the signatures representative of malfunctions comprises an operation of measuring a duration between two successive occurrences of the aforementioned signatures, as well as an operation of calculating an average of these durations, for the calculation of a stability parameter.
- the duration measured is the duration between two successive occurrences of the same signature, that is to say between two successive appearances of a specific malfunction of a given application.
- the duration measured represents the time interval separating two successive occurrences of the same malfunction of a given application.
- the duration measured is the time interval separating two successive occurrences of malfunctions of a given application, the two successive malfunctions between which this duration is measured possibly being different.
- the duration measured is the time interval separating the occurrence of two identical or different signatures of the same application.
- the invention provides that an average of the durations measured is calculated during the step of analyzing the si- gnatures representative of malfunctions and that this average of measured durations makes it possible to obtain a stability parameter.
- the counting and the duration measurement as mentioned above can be carried out daily, or they can be carried out between the moment when the vehicle starts and the moment when it is stopped, whatever the number of these operations. during the day.
- the method according to the invention comprises a step of assigning, to each application on board the vehicles of the set of motor vehicles, a criticality label as previously defined.
- the invention provides that the step of analyzing the signatures representative of malfunctions of one or more applications on board the vehicles and/or the step of deactivating an application is conditioned by the criticality label assigned to this application.
- the invention provides that only applications assigned the "non-critical" label as defined above can be deactivated.
- the analysis step comprises a calculation of an appearance parameter of the signatures representative of malfunctions of an application and a comparison of this appearance parameter with a value of a first threshold.
- the appearance parameter can be defined as the product of the number of occurrences counted during the analysis step previously described by the number of vehicles on which these malfunctions occurred.
- the appearance parameter can be defined by the product of the number of occurrences of a given signature and the number of vehicles having presented the malfunction resulting in this signature.
- the appearance parameter can be defined as the product of the number of occurrences of malfunctions of the same application and the number of vehicles on which this application presented a malfunction, whatever it is .
- the appearance parameter is compared to a value of a first threshold.
- the value of the first threshold depends in particular on the type of calculation performed to define the appearance parameter.
- the first threshold can be arbitrarily set at a value of a few hundreds, when the appearance parameter is defined by the number of occurrences of a given signature, and it can arbitrarily be set at a value of a few thousand, when the appearance parameter is defined by the product of the number of occurrences of a given signature and the number of vehicles having presented the malfunction resulting in this signature.
- the first threshold can be fixed at a first value of the order of a thousand, whereas, for a signature corresponding to a malfunction major, imperatively requiring an immediate restart of the application, the first threshold can be set at a second value lower than the first value mentioned above and by only a few hundred.
- the analysis step comprises a calculation of a stability parameter of an application and a comparison of this stability parameter with a value of a second threshold.
- the stability parameter is therefore established on the basis of the durations measured during the analysis step described above and on the basis of the averages calculated during this analysis step.
- the stability parameter is defined on the basis of an average time interval separating two successive occurrences of the same signature, that is to say separating the occurrence of two successive occurrences of the same malfunction for an application given.
- the second threshold can be arbitrarily set at a duration of between a few tens of seconds and a few minutes: for example, the second threshold can be arbitrarily set at a duration of the order of minute.
- different values can be assigned to the second threshold depending on the application considered, or depending on the type of signatures associated with the same application, depending, for example, on the types of malfunctions associated with these signatures. For example, for a signature of a minor malfunction, not requiring an immediate restart of the application, the second threshold can be set at a few minutes, while, for a signature of a major malfunction, imperatively requiring an immediate restart of the application, the second threshold can be set at only a few tens of seconds.
- the step of deactivating an application is carried out when the parameter for the appearance of malfunctions of an application is greater than the first threshold and/or when the an application's stability parameter is below the second threshold.
- the number of occurrences of different signatures, established during the step of analyzing the signatures representative of malfunctions is compared to the first threshold previously defined.
- the average duration between two successive occurrences of these signatures, established during the step of analyzing the signatures representative of malfunctions is compared with the second threshold previously defined, and the invention provides that an application is deactivated as soon as the first threshold and/or the second threshold is crossed.
- the identification and classification step is carried out prior to the allocation of a criticality label to the applications on board the vehicles.
- all the signatures of all the malfunctions of all the applications, considered as critical or not are identified and classified by the communication system according to the invention, and are analyzed by the latter.
- the criticality label is then assigned to the applications and taken into account for the possible deactivation of the applications assigned the “non-critical” label as previously mentioned. This makes it possible to have a complete and exhaustive database of malfunction signatures, in order, for example, to optimize the operation of all the applications, considered as critical or not, with a view to improving them.
- the identification and classification step is carried out after the assignment of a criticality label to the applications on board the vehicles.
- a criticality label is identified, classified and analyzed by the communication system according to the invention, with a view to possible deactivation of the corresponding "non-critical” applications. .
- the deactivation step is carried out selectively on vehicles present in a geographical area for which the appearance parameter and/or the stability parameter are higher than one of the thresholds .
- the deactivation of an application is then linked to the geolocation of signatures, so that we deactivate the applications of vehicles circulating in a geographical area for which a rate higher than the threshold has been identified. corresponding, and if necessary higher than the corresponding rate for other geographical areas.

- the final step of the method according to the invention is a step of deactivation 18, that is to say a step of transmission, by the communication system 100 as previously described and illustrated by [FIG. l], of a selective order of preventive deactivation of the applications 20i, ..., 20k identified during the aforementioned sorting step 17.
- this deactivation order is sent by the communication system to all the vehicles 2 of the set of vehicles 200, whether or not the applications 20i, ..., 20k have presented one or more malfunctions on these vehicles, and it is effective from the start of the vehicles 2 following receipt of the deactivation order.
- the preventive deactivation of the applications 20i, ..., 20k is a temporary deactivation, until the malfunctions identified are resolved, for example by transmission, by the communication system 100, to the set of vehicles 2 of the set of vehicles 200, of an update of the applications 20i, ..., 20k considered.
- FIG.4 schematically illustrates a second example of the progress of the communication method according to the invention.
- step 16 of assigning a criticality label 40a, 40b to all of the applications 20a, ..., 20n embarked on the vehicles 2 of the set of vehicles 200, is carried out prior to the step of identification and classification 12 previously described.
- the identification and classification step 12 and the parameter calculation step 13 which follows are, according to this example, carried out only on the signatures 30j, ..., 30r corresponding to applications 20j , ..., 20r assigned the "non-critical" label 40b as previously defined, or, in other words, that the sorting step 17 is here substantially confused with the step 16 of assigning the criticality label 40a, 40b, in order to carry out a preliminary sorting of the signatures examined during the analysis step 12.
- the deactivation step 18 that is to say the step of transmitting a preventive deactivation order for the aforementioned applications 20i, ..., 20k, is carried out in the same way as according to example previously described and illustrated by [Fig.3].
- the invention therefore makes it possible, by simple means, on the one hand, to identify, among all the applications on board a plurality of vehicles, the applications which present a number of malfunctions or a frequency of repetitions of these malfunctions deemed too high and, on the other hand, to selectively and preventively deactivate such applications.
- the invention cannot however be limited to the means and configurations described and illustrated, and it also applies to all equivalent means or configurations and to any combination of such means.
- the number and the nature of the thresholds 51, 52 can vary and different thresholds can be defined for different groups of applications and/or different groups of types of malfunctions.
