Description

Method for updating an anti-theft alarm management application, associated device and vehicle.

The invention relates to applications for managing an anti-theft alarm for motor vehicles.

There is a need to make the use of these applications and vehicles more reliable during (or following) the updating of these applications.

• Réception d’une notification de mise à jour de l’application,
• Sur (autrement dit : suite à la) réception de la notification de mise à jour, lecture d’une donnée initiale d’alarme dans une première mémoire dans laquelle est mémorisée l’application de gestion de l’alarme, puis
• Sauvegarde (autrement fit : Ecriture) de la donnée initiale d’alarme dans une deuxième mémoire, extérieure à (autrement dit : distincte de) la première mémoire, puis
• Mise à jour de l’application dans la première mémoire (c’est-à-dire remplacement, au moins en partie, d’une ancienne version de l’application dans la première mémoire par une nouvelle version de l’application. Par exemple la mise à jour écrase (autrement dit : efface) la donnée initiale dans la première mémoire), puis
• Récupération (autrement dit : lecture) de la donnée initiale dans la deuxième mémoire, puis
• Restauration (autrement dit : Ecriture) de la donnée initiale dans la première mémoire.

For this purpose, the invention relates to a method for updating an anti-theft alarm management application, implemented in a motor vehicle, characterized in that it comprises the following steps:

• Receiving an app update notification,
• Upon (in other words: following) receipt of the update notification, reading of an initial alarm data in a first memory in which the alarm management application is stored, then
• Saving (otherwise known as: Writing) the initial alarm data in a second memory, external to (otherwise known as: distinct from) the first memory, then
• Updating the application in the first memory (i.e. replacing, at least in part, an old version of the application in the first memory with a new version of the application. For example, the update overwrites (in other words: erases) the initial data in the first memory), then
• Retrieval (in other words: reading) of the initial data in the second memory, then
• Restoration (in other words: Writing) of the initial data in the first memory.

This way, the application does not lose the initial data after its update, which allows you to find the alarm status before the application update, after the application update.

For example, the updating step comprises a step of receiving a new version of the application or a part of the application (stored in the first memory) from a mobile telephone receiver of the vehicle. For example, the new version is received, by the receiver, from a server, via a mobile telephone network. The new version of the application may also be received from another electronic entity of the vehicle.

The recovery and/or restoration step can be implemented by the application itself or another module.

For example, the step of receiving the update notification comprises a step of receiving the notification (stored in the first memory) from a mobile telephone receiver of the vehicle. For example, the notification is received, by the receiver, from a server (not shown), for example via a mobile telephone network. The new version of the application can also be received from another electronic entity of the vehicle.

The update step may include writing new alarm data, in the first memory, replaced by the initial data during the restore step. However, new alarm data is not necessarily necessary.

For example, the update step may overwrite (that is, erase or modify) the initial data in the first memory.

According to one embodiment, the initial alarm data indicates whether the alarm is activated or not (in other words: monitored or not).

Alternatively, the initial alarm data indicates whether volumetric detection (i.e. which detects a presence in the vehicle) is enabled or disabled (i.e. whether monitoring for a presence in the vehicle is enabled or disabled). More generally, the initial alarm data may indicate a configuration of the alarm.

• Une ouverture d’une porte ou d’un coffre à bagage du véhicule (détection périmétrique), et/ou
• Une présence dans le véhicule (détection volumétrique), et/ou
• Un soulèvement du véhicule (détection d’d’inclinaison).

The anti-theft alarm can be designed to detect a theft or attempted theft. For example, the alarm can detect, using sensors (in the vehicle), an event such as:

• An opening of a door or a luggage compartment of the vehicle (perimeter detection), and/or
• A presence in the vehicle (volumetric detection), and/or
• A vehicle lift (tilt detection).

Upon detection of the event, an alarm signal (for example: a sound) may be output by the alarm, if the alarm is activated (and this step may be part of the method according to the invention). No alarm signal is activated if the alarm is deactivated (and this step may be part of the method according to the invention).

• Redémarrage de l’application de gestion de l’alarme après l’étape de restauration.

According to one embodiment, the method according to the invention comprises the following step:

• Restarting the alarm management application after the restore step.

The restart step may be implemented by restarting the electronic device, a processor of the electronic device, or a processor of the motor vehicle on which the application is executed.

• Blocage (autrement dit : figeage ou fixage) de la donnée initiale d’alarme (dans la première mémoire) (et/ou éventuellement de la nouvelle donnée d’alarme) avant l’étape de sauvegarde jusqu’à (au moins) l’étape de restauration comprise (autrement dit : jusqu’après la fin de l’étape de restauration),
• Déblocage (autrement dit : libération) de la donnée initiale d’alarme (dans la première mémoire) (et/ou éventuellement la nouvelle donnée d’alarme) après l’étape de restauration (comprise) (autrement dit : jusqu’après la fin de l’étape de restauration).

According to one embodiment, the method according to the invention comprises the following steps:

• Blocking (i.e. freezing or fixing) the initial alarm data (in the first memory) (and/or possibly the new alarm data) before the backup step up to (at least) the restoration step (i.e. until after the end of the restoration step),
• Unlocking (i.e.: releasing) the initial alarm data (in the first memory) (and/or possibly the new alarm data) after the restoration step (including) (i.e.: until after the end of the restoration step).

For example, during the blocking step, a first flag is stored in the memory of the vehicle or device. The first flag indicates the impossibility (in other words: prohibits, inhibits or makes impossible) of a modification of the initial data, for example (entry by a driver of the vehicle) from a human-machine interface of the vehicle, for example from a touch screen, or a remote control, or a mobile phone.

For example, during the initial data unlocking step, the first flag is modified or deleted in the vehicle or device memory, or a new first flag is stored in the vehicle or device memory, which indicates the possibility (in other words: authorizes, disinhibits or makes possible) a modification of the initial data, for example (entry by a driver of the vehicle) from a human-machine interface of the vehicle, for example a touch screen, or a remote control, or a mobile phone.

• D’une part, une donnée initiale qui serait modifiée, par un action d’un utilisateur légitime ou non du véhicule, par l’intermédiaire d’une interface homme-machine entre l’étape de sauvegarde et l’étape de restauration, et
• D’autre part, la donnée initiale sauvegardée.

This prevents a risk of inconsistency between;

• On the one hand, initial data which would be modified, by an action of a legitimate or illegitimate user of the vehicle, via a human-machine interface between the backup step and the restoration step, and
• On the other hand, the initial data saved.

For example, during the steps of the method according to the invention, the alarm can detect a break-in and emit an alert signal (and these steps can be part of the method according to the invention), if the alarm is activated. The alarm management application can only manage the control of the configuration and/or the activation of the alarm which can therefore operate during the implementation of the method.

• Blocage (autrement dit : Figeage ou fixage) des ouvrants entre (avant) l’étape de sauvegarde jusqu’à (au moins) l’étape de restauration comprise (autrement dit : jusqu’après l’étape de restauration).
• Déblocage (autrement dit ; libération) des ouvrants (et/ou éventuellement la nouvelle donnée d’alarme) après l’étape de déblocage de la donnée initiale (comprise) (autrement dit : jusqu’après l’étape de déblocage de la donnée initiale).

According to one embodiment, the motor vehicle comprises openings (for example: side doors and/or a luggage compartment hatch), and the updating method comprises the following steps:

• Blocking (in other words: Freezing or fixing) of the openings between (before) the backup step up to (at least) the restoration step (in other words: up to after the restoration step).
• Unlocking (in other words; releasing) the openings (and/or possibly the new alarm data) after the unlocking step of the initial data (included) (in other words: until after the unlocking step of the initial data).

This prevents, for example, the openings from being unlocked while the alarm is activated, which would then trigger the alarm following the restoration step.

For example, during the opening blocking step, a second flag is stored in the vehicle or device memory. The second flag indicates the impossibility (in other words: prohibits, inhibits or makes impossible) of unlocking or locking the openings, for example from a remote control or a mobile phone.

For example, during the step of unlocking the openings, the second flag is modified or deleted in the memory of the vehicle or the device, or a new second flag is stored in the memory of the vehicle or the device, which indicates the possibility (in other words: authorizes, disinhibits or makes possible) of locking or unlocking the openings, for example (controlled) from a remote control or a mobile phone.

The restart step can take place before (or after) the step of unlocking the openings and/or the step of unlocking the initial alarm data.

• Sur réception de la notification de mise à jour de l’application, sauvegarde de l’application dans une troisième mémoire extérieure à la première mémoire et à la deuxième mémoire (autrement dit : disjointe de la première mémoire et de la deuxième mémoire).

According to one embodiment, the method according to the invention comprises the following step:

• Upon receipt of the application update notification, saving the application in a third memory external to the first memory and the second memory (in other words: separate from the first memory and the second memory).

This backup can be used to restore the application, from the second memory to the first memory, in case the update fails.

Following the step of restoring or unlocking the initial alarm data, or following the restart step, the application is executed by a processor of the electronic device. During this execution, the application reads the initial data in the first memory.

The update step may be preceded by a step of sending a notification following the backup step and/or the step of blocking the initial data and/or the openings. This notification indicates to the electronic entity that sends the new version of the application (to a server via the mobile telephone network, or to an electronic entity of the vehicle) that the vehicle is ready for the update.

The first memory and/or the second memory and/or the third memory is for example a non-volatile memory of the electronic device.

Preferably, the blocking of the openings takes place before the blocking of the initial data and/or the unblocking of the openings takes place after the unblocking of the initial data.

Preferably, the blocking of the openings takes place before the reading of the initial data in the first memory and/or the unblocking of the openings takes place after restoration of the initial data.

The first memory and/or the second memory and/or the third memory is preferably a memory of the motor vehicle and/or the electronic device.

The invention also relates to a computer program comprising instructions, executable by a microprocessor or a microcontroller or a computer, for implementing the steps of the method according to the invention, when it is executed by the microprocessor or the microcontroller or the computer.

The steps of the method can be implemented by an electronic device. The invention therefore also relates to an electronic device configured to implement the steps of the method according to the invention, and a vehicle comprising the device.

The characteristics and advantages of the electronic device, the motor vehicle, or the computer program are identical to those of the method, which is why they are not repeated here.

It is understood that the electronic device, motor vehicle, or other element is “configured to” (or “capable of”) performing or implementing a step or operation, by the fact that the element includes means for (in other words “is shaped to” or “is adapted to”) performing the step or operation. These are preferably electronic means, for example a computer program, data in memory, specialized electronic circuits, wired or wireless connections, or a microprocessor of a microcontroller.

When a step or operation is performed (i.e. implemented) by such an element, this generally implies that the element includes means for (i.e. “is shaped to” or “is adapted to” or “is configured to”) performing the step or operation. Examples include electronic means, such as a computer program, data in memory, specialized electronic circuits, wired or wireless connections, a microprocessor or a microcontroller.

Other features and advantages of the present invention will become more clearly apparent upon reading the detailed description which follows, comprising embodiments of the invention given as non-limiting examples and illustrated by the appended drawings, in which.

Detailed description of an exemplary embodiment of the invention.

With reference to figures 1 to 3, in step S00, the electronic device 110 of the vehicle 100 stores in its memory 116 the management application of the anti-theft alarm 160 of the vehicle 100.

In step S10, the device 110 receives, from a mobile telephone receiver 150 of the vehicle 100, an application update notification.

The notification is for example sent by a server (not shown), for example via a mobile telephone network 200. Alternatively, the notification can be sent by an electronic entity of the vehicle 100.

In step S20, upon receipt of the application update notification, the device 110 saves the application in a memory 114 of the electronic device 110. This backup can be restored in the event of failure of the update.

up to date.

In step S30, the device 110 stores a flag 119 which indicates the impossibility of unlocking or locking the openings of the vehicle 100, in particular the side door 170, for example from a remote control, or a mobile telephone.

In step S40, the device 100 stores a flag 118 which indicates the impossibility (in other words: prohibits, inhibits or makes impossible) of modifying the initial data, for example from a touch screen of the vehicle, or a remote control, or a mobile telephone.

Flags 118 and 119 may also be stored outside the electronic device 110.

In step S50, still following receipt of the update notification, the device 110 reads an initial alarm data in the memory 116 of the device 110.

For example, the initial alarm data indicates whether alarm 160 is activated or not (in other words: monitored or not).

• Une ouverture d’une porte latérale 170 ou d’un coffre à bagage du véhicule 100 (détection périmétrique), et/ou
• Une présence dans le véhicule 100 (détection volumétrique), et/ou
• Un soulèvement du véhicule 100 (détection d’d’inclinaison).

The anti-theft alarm 160 is configured to detect a theft or attempted theft in the vehicle 100. The alarm 160 can for example detect, using sensors (in the vehicle), an event such as:

• An opening of a side door 170 or a luggage compartment of the vehicle 100 (perimeter detection), and/or
• A presence in the vehicle 100 (volumetric detection), and/or
• A vehicle lift 100 (tilt detection).

Upon detection of the event, an alarm signal (e.g. a sound) can be played back by alarm 160, if the alarm is enabled. No alarm signal is activated if alarm 160 is disabled.

In step S60, the device 110 writes the initial alarm data into a memory 115 of the device 110.

At step S70, the device 110 sends a notification indicating to the server (or to the entity which sends the new version of the application which may be inside the vehicle) that the vehicle 100 or the device 110 is ready for the update.

In step S80, the device 110 receives a new version of the application or of a part of the application (stored in the memory 116) from a mobile telephone receiver 150 of the vehicle 100. This new version can be received from a server (not shown), for example via a mobile telephone network 200. The new version of the application can also be received from another electronic entity of the vehicle 100.

In step S90, the device 110 updates the application in the memory 116. In other words, it replaces, at least in part, an old version of the application in the first memory 116 with the new version of the application. During this step, the initial data in the memory 116 is overwritten by the new version of the application.

Steps S80 and S90 may be carried out in parallel, for example by executing the boot program 117.

In step S100, the application is restarted. This restart can be carried out by restarting all or part (for example by restarting the processor 111) of the electronic device 110.

In step S110, the electronic device 110 retrieves (i.e.: reads) the initial data in the memory 115.

In step S120, the electronic device restores (i.e.: writes) the initial data in the memory 116.

In step S130, the application is restarted so as to correctly take into account the initial data. This restart can be carried out by restarting all or part (for example by restarting the processor 111) of the electronic device.

In step S140, the flag 118 is deleted from memory, by the device 110, which indicates the possibility of a modification of the initial data, for example entered by a driver of the vehicle from a touch screen of the vehicle, or a remote control, or a mobile telephone.

In step S150, the flag 119 is deleted from memory by the electronic device 110, which indicates the possibility of locking or unlocking the openings of the vehicle, in particular the side door 170 of the vehicle 110, for example controlled from a remote control or a mobile telephone.

In step S160, the application is executed by the processor 111. During this execution, the application reads the initial data in the first memory 116.

Memories 114, 115, 116 are for example volatile memories.

The invention can be implemented, more precisely, by the processor 111 of the device 110, and the instructions of the boot program 117.

The electronic device may comprise several modules, for example an opening control module capable of locking and unlocking the openings. For example, the flag 119 may be stored in the opening control module.
