Description

Method for carrying out remote actions in an electronic communication device of a vehicle, and associated communication device
Technical Field
The invention relates to the implementation of remote actions in a vehicle, optionally of the mobile type, by means of a requested sequence.
Background
Some vehicles include an electronic communication device (e.g., a computer) coupled to a communication module by wireless waves, typically via a monitoring device (sometimes referred to as a "smart servo box" (BSI)). The communication module serves as a communication interface between a remote tool coupled to a communication network and electronic communication devices of the vehicle to enable actions to be remotely performed in at least one of these electronic communication devices by a technician controlling the tool.
Typically, the action is a remote diagnosis for remotely determining the source of a fault or obstacle in the vehicle at the request of the driver and then providing an opinion when the only driver is available for intervention, or when a review or maintenance operation of the vehicle (optionally accompanied by an intervention date) needs to be advised to the driver.
For example, global remote diagnostics is used to carry out, for each computer family of a vehicle, the identification of the vehicle's computer and of the respective software, the reading of error codes contained in each of the computers, and the reading of the associated background (i.e. the environment recorded when an error exists).
The invention relates to all actions that can be triggered remotely, in particular remote maintenance procedures, reinitiations of learning, recovery of task configuration parameters recorded in the computer with the performed trip, recovery of information relating to diagnostic efficiency ratios, and software downloads (for example for performing updates or correcting anomalies).
When a (remote) tool desires to perform remote diagnostics in a vehicle, the remote tool transmits a requested sequence to the communication module of the vehicle via wireless waves. The received requests are then sent by the communication module to the electronic communication device concerned to cause said electronic communication device to carry out the required diagnostic operations, and the responses to these requests (including the results of these operations) are then transmitted by the communication module in the form of messages to the remote diagnostic tool.
It is noted that the requests in the sequence can be transmitted by the remote diagnostic tool, either sequentially, in which case the communication module transmits said requests to the concerned electronic communication module in turn as well, or globally, in which case the communication module transmits said requests to the concerned electronic communication module in turn by following the sequence defined by the script or sequence OTX known by the communication module.
The sequence OTX ("Open Test sequence eXchange") is a sequence written into the information language in a standardized process and can describe a remote diagnostic sequence eXchange program. The script is a remote diagnostic manipulation list written into an information language (e.g., XML) and used to be compiled to perform a task.
Currently, when a communication module transmits a request to an electronic communication device, the communication module triggers a delay (or "timeout") to wait for a response before the delay expires. Also, when an electronic communication device receives a remote diagnostic request, the electronic communication device processes the remote diagnostic request and transmits a response to the remote diagnostic request to the communication module, while triggering a delay. In the case of the communication protocol KWP2000(ISO14230) or UDS (ISO14229), the duration of the delay is equal to 5 seconds. If the communication module does not receive a response at the end of the delay or the electronic communication device does not receive other remote diagnostic requests, the remote diagnostic session is closed and therefore a new session needs to be opened if the electronic communication device is the receiving device for other requests in the same sequence.
It is understood that in order for the sequence of requests to be fully implementable, all computers of the vehicle need to be brought into an information retrieval time constraint. However, when delays are frequently not followed, this causes a sequence of process errors that typically at least partially prevent the implementation of remote diagnostics. As the transmission time of the request and the transmission time of the generated response increase significantly, the process errors are more frequent when the vehicle comprises a plurality of gateways serving as interfaces between two of the loaded communication networks.
Disclosure of Invention
The invention aims in particular to improve the situation.
The invention provides, in particular, for this purpose, a method for enabling a remote action to be carried out in a vehicle by means of a requested sequence, the vehicle comprising a communication device which can communicate with a remote vehicle and which is coupled to a loaded electronic communication device.
The method is characterized in that the method comprises:
-a first step in which the tool transmits to the communication means a sequence of requests, each comprising at least one device identification code representative of one of the electronic communication devices and at least one definition of an operation to be carried out by said one of the electronic communication devices,
-a second step in which the communication device opens an action session for each device identification code contained in the sequence and transmits the request in sequence(s) to the electronic communication device represented by the device identification code associated with the opened action session, with a delay being triggered, and
-a third step in which the communication means store a response to the request, taking into account the moment of response with respect to the associated delay, and then transmit to the tool a message containing the response, the response being stored in correspondence with the associated device identification code according to the order defined by the sequence.
Thus, the number and complexity of actions that may be performed remotely in a vehicle may be increased while significantly reducing the time to exchange requests between the vehicle and the vehicle.
The method according to the invention may comprise other features that may be adopted individually or in combination, in particular:
-in said first step, each request may further comprise a request identity, and in said second step, said communication device may check whether each request represented by a received request identity associated with a received device identity is allowed to be transmitted to the electronic communication device represented by said received device identity, and may then transmit in sequence said request allowed to be transmitted;
Figure BDA0001429484960000031
in the second step, when the request represented by the received request identification code associated with the received device identification code is not allowed to be transmitted to the electronic communication device represented by the received device identification code, the communication means may store a response indicating that the electronic communication device is not likely to respond to the request;
in said third step, when a response to a request transmitted by an electronic communication device does not arrive at the end of the associated delay, said communication means may transmit a message to the electronic communication device for determining whether the electronic communication device is present at least once and may maintain the associated action session open, and then when a response to each transmitted message is not present, said communication means may store a response representing the absence of a response to the request for the electronic communication device concerned;
in a variant, in said third step, when a response to a request transmitted by the electronic communication device does not arrive at the end of the associated delay, said communication means may increment a counter by one unit and, when the incremented value of the counter is less than a threshold, said communication means may retransmit the request to the electronic communication device and trigger again the associated delay, whereas, when the incremented value of the counter is equal to said threshold, said communication means may store a response indicating the absence of a response to the request of the electronic communication device;
-in said third step, when a response to a request transmitted by the electronic communication device arrives before the end of the associated delay, said communication means can determine whether the response contains at least one code representative of the delay requirement, in the affirmative case said communication means can determine whether the number of consecutive responses containing such a code and having been received from the electronic communication device is less than a predetermined threshold, in the affirmative case said communication means can trigger the associated delay again, and in the negative case said communication means can store a response representative of the absence of a response to the request of the electronic communication device;
the method can be used to remotely implement actions selected among remote diagnostics, remote maintenance procedures and software downloads.
The invention also provides a communication device for mounting on a vehicle comprising an electronic communication device carried thereon, the communication device comprising a communication module capable of communicating with a remote tool and coupled to the electronic communication device.
The device is characterized in that it further comprises processing means, in the case of reception of a sequence of requests from the tool, said requests being capable of carrying out remote actions and each comprising at least one device identification code representative of one of said electronic communication devices and at least one definition of an operation to be carried out by said one of said electronic communication devices, said processing means being configured for:
-opening an action session for each device identity contained in the sequence and transmitting the request in sequence to the electronic communication device represented by the device identity associated with the opened action session, while triggering a delay, and
-storing a response to said request, taking into account the moment of response with respect to said associated delay, and then commanding said communication module to transmit to said tool a message containing said response, said response being stored in correspondence with the associated device identification code according to the order defined by said sequence.
The invention also relates to a vehicle, optionally of the motorized type, comprising a loaded electronic communication device and a communication device of the above-mentioned type.

Detailed Description
The object of the present invention is, inter alia, to provide a method of performing remote actions and an associated communication device DC for enabling remote actions in a vehicle V comprising an electronic communication device EEj.
In the following, as a non-limiting example, the vehicle V in which the remote action can be implemented is considered to be of the motorized type. The vehicle is, for example, a car. The invention is not limited to this type of vehicle. The invention relates to virtually any type of transport means on land, on sea (or on a river), or in the air, provided that it comprises an electronic communication device coupled to a communication means that can communicate with a communication network by means of wireless waves, and in which remote action operations can be implemented.
Furthermore, in the following, the action is considered, as a non-limiting example, a remote diagnosis. The invention is not limited to this type of action. The invention relates to virtually all actions that can be triggered remotely, in particular remote maintenance procedures, reinitiations of learning, recovery of task configuration parameters recorded in the computer as the vehicle is driven, recovery of information relating to the diagnostic efficiency ratio, and software downloads (for example for performing updates or correcting anomalies).
A communication network RC is schematically shown in fig. 1, which is coupled to a tool OD, a server SC and a communication device DC according to the invention loaded in a vehicle V further comprising an electronic communication device EEj.
For example, as shown in non-limiting illustration, the electronic communication device EEj is connected to at least one loaded communication network RCE, optionally multiplexed.
An "electronic communication device" is understood here to be a device which is able to receive and process digital data frames communicated in a bus of a loaded communication network RCE connected thereto and to provide data frames for at least one other electronic communication device to the communication network RCE. The electronic communication device may be, for example, a computer, a sensor, or an actuator.
Note that in the example shown in non-limiting manner on fig. 1, the vehicle V comprises four electronic communication devices EEj (j ═ 1 to 4). The number of electronic communication devices EEj may take any value greater than or equal to one.
It is further noted that in the example shown in non-limiting manner in fig. 1, the vehicle V also comprises a monitoring device ES connected to the communication network RCE and to the communication means DC on board. The monitoring device ES is an electronic communication device which is in particular responsible for ensuring an interface between the communication device DC and the further electronic communication device EEj and for controlling the diagnostic functionality. Such as those sometimes referred to as "smart servo boxes" (or BSIs) by those skilled in the art.
Further, each vehicle V is associated with a vehicle identification code. The Vehicle Identification Number may be referred to, for example, in english as the "Vehicle Identification Number" (or VIN).
The communication network RC includes, for example: on the one hand, a wireless communication infrastructure DC-connectable with a communication device disposed in the vehicle V; and, on the other hand, a wired communication infrastructure connectable to wired communication devices, such as the server DC and the tool OD. It is noted that the communication device DC and the wired communication apparatuses SC and OD may be connected with different communication networks which are preferably interconnected with each other via the internet.
The tool OD is configured to implement remote actions in the vehicle V (and more specifically in at least some of the electronic communication devices EEj), optionally under the requirements of the communication device DC or under the requirements of wireless communication devices used by passengers of the vehicle. Each action performed in a vehicle V varies with the vehicle identification code of that vehicle V.
It is contemplated that the tool OD is here a remote diagnostic tool since the action is here considered remote diagnostic.
The tool OD is for example a stationary or portable computer connected to the communication network RC and used by a remote manipulator or by a repairman who is able to remotely control the implementation of an action (here remote diagnosis) and for example provide recommendations when the action is implemented. Furthermore, the tool OD may be, for example, attributed to an after-market service of a vehicle manufacturer (here a motor vehicle manufacturer).
The tool OD comprises, in particular, a software module (or "software") integrally constituting a program similar to that provided in a diagnostic tool used by technicians working on the vehicle (or on the rental grounds), for example, the so-called "software" program
Figure BDA0001429484960000071
And for diagnosing and repairing problems in a typical snowflake brand vehicle (by downloading, coding, pairing/learning replacement parts).
The tool OD may comprise a memory component MS in which definitions of all actions (here diagnostics) that can be performed remotely for at least some of the vehicle models of at least one brand are stored, said some of the vehicle models being identified by a vehicle identification code. These memory means MS may have any form known to the person skilled in the art, in particular in the form of a memory, or in the form of a database.
The communication device DC according to the invention comprises a communication module MC and a processing means MT. It is noted that the communication device DC is a fixed electronic device, or an electronic device added and removable, such as a peripheral interface device (or "dongle") connectable to a diagnostic socket associated with a monitoring device of the vehicle.
The communication module MC can in particular talk to the tool OD in order to request an action to be carried out in the vehicle V (here remote diagnosis) and to transmit the vehicle identification code of the vehicle V to the tool. The communication module includes a circuit (or "hardware") and a software module (or "software"). The communication module also serves as a communication gateway ("gateway") between the tool OD and the electronic communication device EEj of the vehicle V via the monitoring device ES for transmitting the sequence of requests and response messages in response to these requests.
It is understood that these transmissions of the requested sequence and response messages serve to enable the tool OD, which temporarily communicates with the vehicle V via the communication module of the communication device DC, to carry out a remote action (here a diagnosis) and then optionally to transmit the action result to the vehicle V.
Each request in the sequence includes at least one device identification code representing one of the electronic communication devices EEj and at least one definition of an operation to be performed by the one of the electronic communication devices EEj. Note that each definition of an operation may optionally be an operation identification code. Preferably, each request also includes a request identification code, the benefits of which will be understood below.
It is noted that in order to make requests transmittable in the at least one communications network RCE of the vehicle V loaded, the requests need to be in the form of frames conforming to the communications Protocol used in the bus of the at least one communications network, for example the CAN Protocol, and in order to make these frames (CAN) reachable at the monitoring device ES location via the network IP, these frames need to be further encapsulated in TCP/IP ("Transmission Control Protocol/Internet Protocol"). Preferably, the communication module MC is responsible for generating all the encapsulation aspects. In this case, the communication module MC is responsible for decapsulating the frames encapsulated per TCP/IP to reclaim a unique frame CAN in order to transmit them to the receiving device. Likewise, the communication module MC is responsible for encapsulating the frame CAN comprising the response message per TCP/IP so that said frame is transmitted to the tool OD.
The communication module MC may be of the 3G or 4G type, for example, so as to be reachable directly by its IP address (private and supplied by the operator by contract, or public and temporarily sent by the operator to an address that is in the range of the communication session and is considered private only during the duration of the communication session).
When the vehicle V optionally applies for remote diagnosis at the request of the driver, the communication means DC of the vehicle initiate a (optionally voice) data communication with the vehicle OD, optionally via the communication server SC. Optional voice (or telephone) communication is used to enable a remote manipulator or repairman using the tool OD to speak over the telephone with the passengers of the vehicle V. Data (or "data") communications are established, for example, in the form of IP ("Internet Protocol"). The communication device DC can be directly connected via the internet with an optional communication server SC, since the communication device knows the IP address of the communication device.
It is noted that the optional communication server SC may be attributed to an after-market service of a vehicle manufacturer, here a motor vehicle manufacturer. The communication server may also be part of a system that also includes the tool OD.
As described above, the present invention provides a method of performing remote actions for performing remote actions in a vehicle V. The method can be carried out by means of the communication device DC and at least one tool OD. This method comprises three steps.
The first step of the method according to the invention is initiated when an action has to be carried out in the vehicle V, either at the request of the driver of the vehicle V, or at the request of the passenger carrying the vehicle V, or at the initiative of the person controlling the vehicle OD.
In this first step, the tool OD generates or carries a requested sequence, which is then transmitted to the communication module MC of the communication device DC of the vehicle V concerned. The sequence of requests includes requests that each include at least one device identification code representing one of the electronic communication devices EEj of the vehicle V and at least one definition of an operation to be performed by the one of the electronic communication devices EEj.
The transfer takes place via an optional communication server SC and a communication network RC.
In a second step of the method according to the invention, the communication device DC opens an action session (for example a remote diagnosis session) for each device identification code contained in the received sequence. And the communication device transmits the requests in the sequence (according to the order defined by the sequence) to the electronic communication device EEj represented by the device identification code associated with the just-opened action session (e.g., remote diagnostic session) in the sequence, while triggering a delay (or "time out").
The duration of the delay depends on the communication protocol used between the communication module MC and the electronic communication device EEj. For example, when the communication protocol is KWP2000(ISO14230) or UDS (ISO14229), the duration of the delay may be equal to 5 seconds.
It is noted that the processing means MT of the communication device DC control the opening of the action session for each equipment identity and command the communication module MC to transmit the request in a sequence. This transmission takes place via the optional monitoring device ES and the loaded communication network RCE.
It is also noted that in order to make the implementation of the action safer, as described above, in a first step the tool OD may add a request identification code to each request in the sequence. In this case, in a second step, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) checks whether each request represented by the received request identification code associated with the received device identification code is allowed to be transferred to the electronic communication device EEj represented by said received device identification code. The communication means DC (and more precisely the communication module MC of said communication means) then transmit (according to the order of said processing means MT) in sequence the request to allow the transmission to the electronic communication device EEj concerned.
This check is carried out by the processing means MT on a memory means which stores the request identification code in correspondence with the device identification code. These memory means may be arranged in the communication device DC (and optionally in the processing means MT of said communication device). But this is not essential. In fact, the storage means may deviate, for example, into the monitoring device ES or into the communication server SC, for example. In this case (complete deviation), the storage means needs to store the request identification code in correspondence with the device identification code and the vehicle identification code. Furthermore, these memory means may have any form known to the person skilled in the art, in particular in the form of a memory, optionally of the software type, or in the form of a database.
Preferably, in the second step, when the request represented by the received request identification code associated with the received device identification code is not allowed to be transmitted to the electronic communication device EEj represented by the received device identification code, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) stores a response indicating that it is not possible for the electronic communication device EEj concerned to respond to the request. For example, the response includes an expression of the type "condition not satisfied", or a dedicated identification code. The response is stored in correspondence with the request identification code concerned. Furthermore, this response is then transmitted through the communication module MC together with other responses to other requests, as will be described below.
In case said option exists, the processing means MT organizes an action session with the electronic communication device EEj only if the request is allowed to be transmitted via the communication module MC to the electronic communication device EEj.
Upon receiving the request, the electronic communication device EEj attempts to perform each operation defined by the request (e.g., by an operation identification code). The electronic communication device EEj then transmits a response to the request to the communication module MC via the optionally loaded communication network RCE and the monitoring device ES when it is able to do so.
In a third step of the method according to the invention, the communication device DC (and more precisely the processing means MT of said communication device) stores a response to said request, taking into account the response instant with respect to said associated delay. The communication means DC (and more precisely the communication module MC of said communication means) then transmit a message to the tool OD containing responses stored in correspondence with the associated device identification codes according to the order defined by the sequence previously received.
In fact, the order of the responses in the response message is the same as the order that the corresponding requests in the script (or equivalent portion) of the sequence have.
If at the end of the delay the communication module MC does not receive a response or the electronic communication device EEj does not receive other remote diagnostic requests, the remote diagnostic session is closed and therefore a new session needs to be opened if the electronic communication device EEj is the receiving device for the same sequence of other requests.
It is noted that in the third step, if a response to the request transmitted by the electronic communication device EEj does not arrive at the end of the initial associated delay, the communication means DC may transmit a message for determining whether the electronic communication device is present to the electronic communication device EEj, for example at least once, and maintain the associated action session open. This message may for example be of the type known to the person skilled in the art as a message called "testpresent" because it is used in the communication protocol KWP2000 or UDS to maintain the session active when no other requests are received by the same electronic communication device EEj that has received the previous request.
The number of messages that can be transmitted in turn to the electronic communication device EEj for determining presence is configurable (at least equal to one). Further, these messages for determining presence may be transmitted periodically according to a period of time strictly less than the delay duration.
Then, when a response to each message for determining presence transmitted to the electronic communication device EEj does not exist, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) stores a response representing the absence of a response to this request of the involved electronic communication device EEj. For example, the response includes an expression of the type "response does not exist" or "condition is not satisfied", or a dedicated identification code. The response is stored in correspondence with the request identification code concerned. Furthermore, this response is then transmitted through the communication module MC together with other responses to other requests.
In an implementation variant, in a third step, the communication device DC (and more precisely the processing means MT of said communication device) may, for example, cause the current value n of the counter to be reached if the response to the request transmitted by the electronic communication device EEj does not arrive at the end of the initial associated delayerIncrement by one unit. Then, if the incremented (new) value n of the countererBelow the threshold s2, the communication device DC (and more precisely the communication module MC of said communication device) retransmits the request to the electronic communication apparatus EEj and again triggers the associated delay. The processing means MT orders each retransmission of said request and each retriggering an associated delay.
If, instead, the counter is incremented by a (new) value nerEqual to the threshold s2, the communication device DC (and more precisely the processing means MT of said communication device) stores a message indicating this request for the electronic communication equipment EEj concernedThe response is not found. For example, the response includes an expression of the type "response does not exist" or "condition is not satisfied", or a dedicated identification code. The response is stored in correspondence with the request identification code concerned. Furthermore, this response is then transmitted through the communication module MC together with other responses to other requests.
It is noted that in the third step, if a response to the request transmitted by the electronic communication device EEj arrives before the end of the associated delay, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) may determine whether the response contains at least one code representing the latency requirement. For example, each code may be of the NRC ("Negative response code") 0x78 or NRC 0x21 type. These types of codes are known to those skilled in the art because they are used by the electronic communication device EEj for requiring a delay extension when the required operations are performed for a long time.
If the response does contain at least one code of the above-mentioned type, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) can determine the number n of consecutive responses that contain such a code and that have been received from the electronic communication device EEjcaIs less than the predetermined threshold s 1. In the affirmative case the communication device DC (and more precisely the processing means MT of said communication device) again triggers the associated delay and then waits for the full response of said electronic communication device EEj. In the negative case, the communication apparatus DC (and more precisely the processing means MT of said communication apparatus) stores a response indicating the absence of a response to this request by the electronic communication device EEj concerned. For example, the response includes an expression of the type "response does not exist" or "condition is not satisfied", or a dedicated identification code. The response is stored in correspondence with the request identification code concerned. Furthermore, this response is then transmitted through the communication module MC together with other responses to other requests.
Fig. 2 schematically shows a first example of an algorithm which implements a first exemplary embodiment of the method according to the invention.
In substep 10, the diagnostic tool OD transmits the requested sequence to the communication module MC of the communication device DC of the selected vehicle V.
The first step of this first example of the method according to the invention corresponds to this sub-step 10.
In substep 20, the communication device DC of the selected vehicle V receives the transmitted sequence.
Then, in sub-step 30, the communication means DC check whether each request is allowed to be transmitted to the electronic communication device EEj concerned. In other words, the communication apparatus checks whether the execution condition of each request is satisfied. If this is not the case for a request associated with the electronic communication device EEj, the communication means DC will perform a sub-step 80 in which the communication means stores a response indicating that it is not possible for the electronic communication device EEj to respond to the request.
Conversely, if the request is allowed to be transmitted to the electronic communication device EEj, the communication means DC will perform sub-step 40 in which the communication means opens an action session for the associated device identity in the received sequence and transmits the first request in the sequence to the electronic communication device EEj represented by the device identity associated with the just opened action session, while triggering a delay.
The second step of this first example of the method according to the invention corresponds to sub-steps 20 to 40.
Then, in sub-step 50, the communication device DC checks whether the communication device receives a response from the electronic communication apparatus EEj at the end of the delay associated with the request transmitted to the electronic communication apparatus EEj.
In the negative case, the communication means DC performs a sub-step 60 in which it transmits at least once to the electronic communication device EEj a message for determining whether the electronic communication device is present, and maintains the associated action session open before returning to perform sub-step 50.
In the affirmative case (and therefore in the case where the communication means receives a response from the electronic communication device EEj), the communication means DC performs a substep 70 in which the communication means checks whether the response contains at least one code indicating a delay requirement.
If the response does not contain such a code, this means that the electronic communication device EEj has transmitted a complete response to the request, and therefore the communication means DC will perform the substep 80 for storing the response.
If, on the contrary, the response does contain at least one code of the above-mentioned type, the communication means DC performs a sub-step 90 in which the communication means determine the number n of consecutive responses that contain such a code and that have been received from the electronic communication device EEjcaIs less than the predetermined threshold s 1.
In the negative case, the communication means DC will perform a sub-step 80 for storing a response indicating that no response to the request of the electronic communication device EEj concerned is present.
In the affirmative, the communication means DC performs a sub-step 100, in which 100 it retriggers the delay associated with the request transmitted to the electronic communication device EEj in question, and then returns to performing the sub-step 50.
When the communication device DC has stored a response to the request, it returns to execute a new sub-step 40 for the next request in the sequence.
Finally, when the communication means DC have stored all the responses to all the requests in the sequence, they perform a sub-step 110, in which 110 they transmit a message to the tool OD containing the responses, which are stored in correspondence with the associated device identification codes according to the order defined by the sequence.
The third step of this first example of the method according to the invention corresponds to sub-steps 50 to 110.
Fig. 3 schematically shows a second example of an algorithm, which implements a second exemplary embodiment of the method according to the invention.
In sub-step 10', the diagnostic tool OD transmits the requested sequence to the communication module MC of the communication device DC of the selected vehicle V.
The first step of this second example of the method according to the invention corresponds to this sub-step 10'.
In sub-step 20', the communication device DC of the selected vehicle V receives the transmitted sequence.
Then, in sub-step 30', the communication means DC check whether each request is allowed to be transmitted to the electronic communication device EEj concerned. In other words, the communication apparatus checks whether the execution condition of each request is satisfied. If this is not the case for a request associated with the electronic communication device EEj, the communication means DC will perform a sub-step 100 ', in which 100' the communication means store a response indicating that it is not possible for the electronic communication device EEj to respond to the request.
Conversely, if the request is allowed to be transmitted to the electronic communication device EEj, the communication means DC will perform sub-step 40 ', in which 40' the communication means open an action session for the associated device identity in the received sequence and transmit the first request in the sequence to the electronic communication device EEj represented by the device identity associated with the just opened action session, while triggering a delay.
The second step of this second example of the method according to the invention corresponds to sub-steps 20 'to 40'.
Then, in sub-step 50', the communication device DC checks whether it receives a response from the electronic communication apparatus EEj at the end of the delay associated with the request transmitted to the electronic communication apparatus EEj.
In the negative case, the communication means DC perform a sub-step 60 ', in which 60' they cause the current value n of the countererIncrement by one unit (i.e. n)er＝ner+1)。
Then, the communication means DC performs a sub-step 70 ', in which 70' the communication means check whether the incremented (new) value of said counter is smaller than a predetermined threshold s 2.
If the incremented (new) value of said counter is equal to the threshold value s2, the communication device DC will perform a sub-step 100' for storing a response indicating that no response exists for the current request processed by the electronic communication apparatus EEj concerned.
Conversely, if the incremented (new) value of the counter is less than the threshold value s2, the communication device DC performs a sub-step 80 ', in which 80 ' the communication device retriggers the delay associated with the request transmitted to the considered electronic communication device EEj, before retransmitting the considered request in sub-step 50 '.
If the result of sub-step 50 ' is positive (and therefore if the communication means DC receives a response from the electronic communication device EEj in the associated delay), the communication means DC performs sub-step 90 ', in which sub-step 90 ' the communication means checks whether the response contains at least one code indicating a delay requirement.
If the response does not contain such a code, this means that the electronic communication device EEj has transmitted a complete response to the request, and therefore the communication means DC will perform substep 100' for storing the response.
If, on the contrary, the response does contain at least one code of the above-mentioned type, the communication means DC perform a sub-step 110 ', in which 110' the communication means determine the number n of consecutive responses that contain such a code and that have been received from the electronic communication device EEjcaIs less than the predetermined threshold s 1.
In the negative case, the communication means DC will perform a sub-step 100' for storing a response indicating that no response to the request of the electronic communication device EEj concerned is present.
In the affirmative, the communication means DC performs a sub-step 120 ', in which 120 ' they re-trigger the delay associated with the request transmitted to the electronic communication device EEj in question, and then returns to performing the sub-step 50 '.
When the communication device DC has stored a response to the request, it returns to perform a new sub-step 40' for the next request in the sequence.
Finally, when the communication device DC has stored all the responses to all the requests in the sequence, it performs a sub-step 130', in which it transmits to the tool OD a message containing the responses stored in correspondence with the associated device identification codes according to the order defined by the sequence.
The third step of this second example of the method according to the invention corresponds to sub-steps 50 'to 130'.
The present invention provides a number of advantages, including:
the number and complexity of actions that can be performed remotely in the vehicle can be increased,
-the time to exchange requests between the vehicle and the transport is reduced considerably,
increased efficiency of road assistance and immediate troubleshooting in some cases,
