Abstract

A monitoring method is implemented in a land vehicle, on the one hand, comprising a charging connector coupled to a rechargeable battery coupled to a GMP having first and second states in which it is respectively inactive and active, and to which a coupling connector is capable of being connected, and, on the other hand, having a procedure prohibiting its movement in the event of detection of a coupling connector connected to the charging connector.

Description

Title of the invention: MONITORING OF THE CHARGING CONNECTOR OF A LAND VEHICLE TO DETECT AN ABNORMAL CONNECTION Technical field of the invention

[0001] The invention relates to land vehicles comprising a charging connector coupled to a rechargeable battery, and more specifically to the monitoring within such vehicles of the charging connector. State of the art

[0002] Certain land vehicles, possibly of the automobile type, comprise a rechargeable battery coupled to a charging connector allowing it to be recharged when a coupling connector, coupled to an external power source (such as for example a charging station), is temporarily connected to it.

[0003] Generally, this rechargeable battery is in particular responsible for powering an electric motor of the powertrain (or GMP) of the (land) vehicle, and therefore constitutes a main (or "traction" or "power" battery). It will be noted that the invention relates to both all-electric GMP vehicles and hybrid (thermal and electric) GMP vehicles, provided that they include a battery rechargeable by an external power source.

[0004] For safety reasons, the vehicles presented above have an immobilization procedure which is capable of prohibiting their movement in the event of detection of a coupling connector connected to the charging connector. It will be understood that a vehicle, whose charging connector is temporarily coupled to an external power source via a charging cable, must not be able to move, because this could cause potentially dangerous and / or penalizing damage when it prevents the next recharges of the rechargeable battery.

[0005] Some malicious people who are aware of this immobilization procedure equip themselves with a coupling connector (generally separate from its charging cable), and open the hatch giving access to the charging connector of a vehicle stopped with its driver at the wheel (for example at a traffic light or a stop sign) in order to connect their coupling connector to this charging connector to immobilize the vehicle. The objective is to make the driver leave the passenger compartment so that he can go and check what is happening at the charging connector, then take possession of the vehicle without breaking in and / or attack the driver, possibly to steal it. This is therefore a new form of road piracy (or "car-jacking") made possible by the vehicle immobilization procedure, which is also very useful.

[0006] The invention therefore aims in particular to improve the situation by detecting an abnormal connection of a coupling connector to the charging connector of a vehicle. Presentation of the invention

[0007] It proposes in particular for this purpose a monitoring method intended to be implemented in a land vehicle, on the one hand, comprising a charging connector coupled to a rechargeable battery coupled to a powertrain having first and second states in which it is respectively inactive and active, and to which a coupling connector is capable of being connected, and, on the other hand, having a procedure capable of prohibiting its movement in the event of detection of a coupling connector connected to the charging connector.

[0008] This monitoring method is characterized by the fact that it comprises a step in which, in the presence of this detection, it is determined whether at least one condition of use or current location of the vehicle is satisfied, and, if so and if the powertrain is in its second state, a driver of the vehicle is asked if he wishes the latter to move, and, if so, the procedure is deactivated.

[0009] Thanks to the invention, in the presence of an abnormal connection, the driver can continue or begin his journey without needing to get out of his vehicle to remove the DC coupling connector, which greatly reduces the probability of carjacking.

[0010] The monitoring method according to the invention may include other characteristics which may be taken separately or in combination, and in particular:

[0011] - in its step, each condition of use or location in progress of the vehicle can be chosen from a movement of a distance greater than a first threshold since the powertrain is in its second state, a central locking of the vehicle doors activated for at least a first predefined duration, at least one seat belt locked for at least a second predefined duration, and a distance separating the vehicle from an electric charging station greater than a second threshold;

[0012] - in its step, when the driver wants the vehicle to move and a worm central locking of vehicle doors is deactivated, central locking of doors can be activated;

[0013] - in its step, when the driver wants the vehicle to move, one can also trigger operation of at least one audible alert device or vehicle light;

[0014] - in the presence of the last option, in its step, each sound alert device or luminous may be chosen from a luminous danger warning device, an audible alarm device against theft and / or intrusion, and an audible warning device;

[0015] - also in the presence of the last option, in its step, one can trigger a stopping the operation of each audible or visual alert device put into operation after disconnection of the coupling connector from the charging connector;

[0016] - in its stage, in case of refusal of the driver to move the vehicle, one can provide the driver with an audible message and / or a text message intended to draw his attention to the ongoing connection of the coupling connector to the charging connector, and the procedure can be kept active as long as the coupling connector has not been disconnected from the charging connector.

[0017] The invention also provides a computer program product comprising a set of instructions which, when executed by processing means, is capable of implementing a monitoring method of the type presented above, in a land vehicle, on the one hand, comprising a charging connector coupled to a rechargeable battery coupled to a powertrain having first and second states in which it is respectively inactive and active, and to which a coupling connector is capable of being connected, and, on the other hand, having a procedure capable of prohibiting its movement in the event of detection of a coupling connector connected to the charging connector, to detect an abnormal connection of a coupling connector to the charging connector.

[0018] The invention also proposes a monitoring device intended to equip a land vehicle, on the one hand, comprising a charging connector coupled to a rechargeable battery coupled to a powertrain having first and second states in which it is respectively inactive and active, and to which a coupling connector is capable of being connected, and, on the other hand, having a procedure capable of prohibiting its movement in the event of detection of a coupling connector connected to the charging connector.

[0019] This monitoring device is characterized by the fact that it comprises at least one processor and at least one memory arranged to carry out the operations consisting, in the presence of this detection, in determining whether at least one condition of use or current location of the vehicle is satisfied, and, if so and if the powertrain is in its second state, in triggering a request intended to determine whether a driver of the vehicle wishes to move the latter, and, if so, in triggering a deactivation of the procedure.

[0020] The invention also proposes a land vehicle, possibly of the automobile type, and, on the one hand, comprising a monitoring device of the type of that presented above and a charging connector coupled to a rechargeable battery coupled to a powertrain having first and second states in which it is respectively inactive and active, and to which a coupling connector is capable of being connected, and, on the other hand, having a procedure capable of prohibiting its movement in the event of detection of a coupling connector connected to the charging connector. Brief description of the figures

[0021] Other characteristics and advantages of the invention will appear on examining the detailed description below, and the appended drawings, in which:

[0022] [Fig. 1] schematically and functionally illustrates an exemplary embodiment of a land vehicle comprising a GMP transmission chain with an electric motor associated with a rechargeable main battery and associated with a supervision computer, and a monitoring device according to the invention,

[0023] [Fig.2] schematically and functionally illustrates an exemplary embodiment of a supervision computer comprising an exemplary embodiment of a monitoring device according to the invention, and

[0024] [Fig.3] schematically illustrates an example of an algorithm implementing a monitoring method according to the invention. Detailed description of the invention

[0025] The invention aims in particular to propose a monitoring method, and an associated monitoring device DS, intended to enable monitoring of a charging connector CN coupled to a rechargeable battery BP coupled to a powertrain (or GMP) of a land vehicle V, to detect an abnormal connection of a coupling connector CC to this charging connector CN.

[0026] In the following, it is considered, by way of non-limiting example, that the land vehicle V is of the automobile type. It is for example a car, as illustrated in [Fig.l]. But the invention is not limited to this type of land vehicle. It relates in fact to any type of land vehicle comprising a GMP transmission chain with an electric prime mover coupled to a battery which is rechargeable by an external power source via a charging connector CR. Thus, it relates to utility vehicles, camper vans, minibuses, coaches, trucks, road machinery, construction machinery, agricultural machinery, and tracked machinery, for example.

[0027] Furthermore, it is considered in the following, by way of non-limiting example, that the (land) vehicle V comprises a transmission chain with a powertrain (or GMP) of the all-electric type (and therefore whose drive is provided exclusively by at least one electric motor MME). But the GMP could be hybrid type (thermal and electric), since it includes a battery rechargeable by an external power source.

[0028] [Fig.l] schematically shows a (land) vehicle V comprising a transmission chain with electric GMP (and therefore with electric motor MME), a supervision computer CS, an on-board network RB, a service battery BS, a rechargeable battery BP, a main electrical circuit CEP connected to a charging connector CN, a charger CH, a converter CV, and a monitoring device DS according to the invention.

[0029] The on-board network RB is an electrical power supply network to which electrical (or electronic) equipment (or components) that consume electrical energy are coupled.

[0030] The service battery BS is responsible for supplying electrical energy to the on-board network RB, in addition to that supplied by the CV converter powered by the rechargeable battery BP via the main electrical circuit CEP, and sometimes instead of this CV converter. For example, this service battery BS can be arranged in the form of a very low voltage type battery (typically 12 V, 24 V or 48 V). It is rechargeable at least by the CV converter. It is considered in the following, by way of non-limiting example, that the service battery BS is of the 12 V Lithium-ion type.

[0031] The main electrical circuit (or "high voltage") CEP is connected, on the one hand, to the rechargeable battery BP via an interface device not shown, and, on the other hand, to electronic equipment, such as for example the converter CV and the electric motor MME. It also allows the rechargeable battery BP to be recharged by an external power source and temporarily coupled to the charging connector CR of the vehicle V via a charging cable with a coupling connector. This main electrical circuit CEP therefore comprises at least one power supply circuit PI ensuring the coupling between the rechargeable battery BP and at least the electric motor MME and converter CV, and a charging circuit P2 connected to the charging connector CR and allowing the rechargeable battery BP to be recharged via an external power source and temporarily coupled to the charging connector CR via a charging cable with a coupling connector.

[0032] In the example illustrated non-limitingly in [Fig.l] the recharging circuit P2 allows the rechargeable battery BP to be recharged not only in direct current (for example mode 4), but also in alternating current (for example mode 2 or 3), under the control of the charger computer (equipping the charger CH) and the battery computer CB (associated with the rechargeable battery BP). But in alternative embodiments not illustrated, the recharging circuit P2 could only allow recharging in direct current or only recharging in alternating current.

[0033] The transmission chain has a GMP which is, here, purely electric and therefore which comprises, in particular, an electric motor MME, a motor shaft, and a transmission shaft. Here, the term "electric motor" means an electric machine arranged so as to provide torque to move the vehicle V when it is supplied with electrical energy, as well as possibly to recover torque in the transmission chain.

[0034] The operation of the transmission chain (and therefore of the GMP) is supervised by a CS supervision computer.

[0035] The electric motor MME (here an electric motor) is here coupled to the rechargeable battery BP via the power supply circuit PI of the main electrical circuit CEP, in order to be supplied with electrical energy, as well as possibly to supply this rechargeable battery BP with electrical energy, for example during a regenerative braking phase.

[0036] Furthermore, this electric motor MME is coupled to the motor shaft, to provide it with torque by rotational drive. This motor shaft is here coupled to a reducer RD which is also coupled to the transmission shaft, itself coupled to a first train T1 (here of wheels), preferably via a differential DF.

[0037] This first train T1 is here located in the front part PVV of the vehicle V. But in a variant this first train T1 could be the one which is here referenced T2 and which is located in the rear part PRV of the vehicle V.

[0038] It will be noted that the GMP has a first state in which it is inactive (i.e. with its electric motor MME stopped) and a second state in which it is active (i.e. with its electric motor MME in operation). The state in which the GMP is placed is known at each instant by a machine computer CM which controls the electric motor MME under the supervision of the supervision computer CS. This state is transmitted by the machine computer CM to the supervision computer CS.

[0039] The CV converter is also responsible, here, during the driving phases of the vehicle V for converting part of the electric current stored in the rechargeable battery BP to supply the on-board network RB and the service battery BS with converted electric current (to recharge it).

[0040] It will be noted, as illustrated non-limitingly in [Fig.l], that the CV converter can be part of the CH charger responsible, at least, for controlling the recharges of the rechargeable battery BP.

[0041] The rechargeable battery BP here powers the electric motor MME, it constitutes a main battery (or “traction” or even “power”). It can, for example, comprise electrical energy storage cells, possibly electrochemical (for example of the lithium-ion (or Li-ion) or Ni-Mh type or Ni-Cd). Also for example, the BP rechargeable battery can be of low voltage type (typically 450 V for illustration). But it could be of medium voltage or high voltage type.

[0042] Furthermore, the rechargeable battery BP is (here) associated with a battery case BB which notably comprises an interface device (not shown), voltage / current measuring means (not shown), and the battery calculator CB. For example, the rechargeable battery BP and the battery case BB may be part of a battery assembly (or “pack”).

[0043] It will also be noted that the vehicle V has an immobilization procedure which is capable of prohibiting its movement in the event of detection of a coupling connector CC connected to the charging connector CN. For example, the detection of the connection of a coupling connector CC to the charging connector CN can be done at the level of a resistance measured on a line called “proximity pilot” (or PP) forming part of the charging connector CN. For example, it is the supervision computer CS which can be responsible for implementing the immobilization procedure, because it is it which decides whether or not to operate the GMP.

[0044] As illustrated non-limitingly in [Fig.l], the charging connector CN may be part of a connection box BC fixed to the body of the vehicle V and accessible by a user via a rotatable access hatch TA. It will be understood that once the access hatch TA is open, it is possible to connect a coupling connector CC to the charging connector CN.

[0045] It will also be noted that in the example illustrated non-limitingly in [Fig.l] the vehicle V also comprises a distribution box BD to which the service battery BS, the converter CV and the on-board network RB are coupled. This distribution box BD is responsible for distributing in the on-board network RB the electrical energy stored in the service battery BS or produced by the converter CV, for the supply of the electrical components (or equipment) coupled to the on-board network RB according to power supply requests received (in particular from the supervision computer CS of the GMP).

[0046] As mentioned above, the invention notably proposes a monitoring method intended to enable monitoring of the CN charging connector, in order to detect an abnormal connection of a DC coupling connector to this CN charging connector.

[0047] This (monitoring) method can be implemented at least partially by the monitoring device DS (illustrated at least partially in Figures 1 and 2) which comprises for this purpose at least one processor PR1, for example a digital signal processor (or DSP ("Digital Signal Processor")), and at least one memory MD. This monitoring device DS can therefore be implemented in the form of a combination of circuits or electrical or electronic components (or "hardware") and software modules (or "software"). For example, this could be a microcontroller.

[0048] The memory MD is RAM in order to store instructions for the implementation by the processor PR1 of at least part of the monitoring method. The processor PR1 may comprise integrated (or printed) circuits, or several integrated (or printed) circuits connected by wired or wireless connections. An integrated (or printed) circuit is understood to mean any type of device capable of carrying out at least one electrical or electronic operation.

[0049] In the example illustrated non-limitingly in Figures 1 and 2, the monitoring device DS is part of the supervision computer CS. But this is not obligatory. Indeed, the monitoring device DS could comprise its own dedicated computer, which is then coupled to the supervision computer CS, or could be part of another on-board computer, such as for example the charger computer.

[0050] As illustrated non-limitingly in [Fig. 3], the (monitoring) method, according to the invention, comprises a step 10-50 which is implemented each time the vehicle V is woken up and it has been detected that a coupling connector CC was connected to the charging connector CN.

[0051] Step 10-50 of the method comprises a sub-step 10 in which, in the presence of the aforementioned detection, it is determined (for example the monitoring device DS) whether at least one condition of current use or location of the vehicle V is satisfied.

[0052] If at least one condition of use or current location of the vehicle V is not satisfied (and therefore in the negative) and / or if the GMP is in its first state (inactive), it is (for example the monitoring device DS) considered that the CC-CN connection is normal. Consequently, sub-step 10 is returned to be performed in order to check again each condition of use or current location and the state of the GMP.

[0053] On the other hand, if at least one (each) condition of use or current location of the vehicle V is satisfied (and therefore in the affirmative), and if in addition the GMP is in its second state (active), the driver of the vehicle V is asked, in a sub-step 20 of step 10-50, if he wishes the vehicle V to be able to move. For example, the monitoring device DS can trigger a request intended to determine if the driver wishes to move the vehicle V.

[0054] It will be understood that in this situation the connection of the DC coupling connector to the CN charging connector is abnormal, because it should not be present. Therefore, it is almost certain that a malicious person has opened the TA access hatch and connected his DC coupling connector to the CN charging connector. CN recharge, as illustrated in [Fig.l], with the aim of causing the immobilization of the vehicle V by its immobilization procedure. The probability of an attempted carjacking is therefore very high.

[0055] The request intended for the driver may be a text message displayed on at least one screen EA of the vehicle V (for example on the dashboard or a central instrument panel) or on the screen of a smartphone of the driver and / or an audio message broadcast by at least one loudspeaker of the vehicle V or of this smartphone. Similarly, the driver may provide his response by pressing a dedicated area of ​​the display screen EA (if it is digital) and / or vocally (if the vehicle V includes a microphone coupled to a voice synthesis device).

[0056] If the connection of the coupling connector CC to the charging connector CN is abnormal (and therefore in the affirmative), step 10-50 of the method also comprises a sub-step 30 in which the immobilization procedure is deactivated (for example the monitoring device DS triggers the deactivation of) in order to allow the movements of the vehicle V although a coupling connector CC is connected to its charging connector CN.

[0057] Thus, if the driver wishes, he can continue or begin his journey without having to get out of his vehicle V to remove the DC coupling connector, which could prove dangerous for him as well as for his vehicle V. This results in a very significant reduction in the probability of carjacking.

[0058] For example, and as illustrated non-limitingly in [Fig. 3], step 10-50 may comprise a sub-step 50 in which, in the event of the driver refusing to move the vehicle V, it is possible to provide (for example the monitoring device DS may trigger the provision of) the driver with an audible message and / or a text message intended to draw his attention to the current connection of a coupling connector CC to the charging connector CN. In addition, in this sub-step 50 it is possible to keep active (for example the monitoring device DS may trigger the maintenance in the active state of) the procedure as long as the coupling connector CC has not been disconnected from the charging connector CN.

[0059] Thus, if the driver wishes, he can remain on site with his vehicle V immobilized by the immobilization procedure, with full knowledge of the facts (thanks to each message provided). He can in particular decide to get out of his vehicle V to disconnect the DC coupling connector, or else stay in the passenger compartment of the vehicle V and, for example, call an emergency service (such as the police) by telephone.

[0060] The text message may be displayed on at least one screen EA of the vehicle V (for example on the dashboard or the central instrument panel) or on the screen of the driver's smartphone. The audio message may be broadcast by at least one loudspeaker speaker of the vehicle V or this smartphone.

[0061] Also for example, in sub-step 10 of step 10-50 each condition of use or current location of the vehicle V can be chosen from:

[0062] - cl: a displacement of a distance greater than a first threshold if since the GMP is in its second (active) state,

[0063] - c2: a central locking of the doors of the vehicle V activated for at least one first predefined duration dl,

[0064] - c3: at least one seat belt locked for at least one second predefined duration d2, and

[0065] - c4: a distance separating the vehicle V from an electric charging station su higher than a second threshold s2.

[0066] Condition cl is a condition of use intended to determine whether the vehicle V is currently making a journey by considering the distance traveled since the activation of its GMP. It will be understood that if the vehicle V has traveled a certain distance, it is because its journey has started and therefore there is no reason for a coupling connector CC to be connected to the charging connector CN. For example, the first threshold si can be between 50 meters and 150 meters. As an illustrative example, the first threshold si can be equal to 100 meters. But other values ​​of the first threshold si can be used.

[0067] Condition c2 is a usage condition intended to determine whether the vehicle V is currently making a journey by considering the time elapsed since the central locking of the doors was activated. It will be understood that if the doors have been locked for a certain time, it is because the journey of the vehicle V began substantially since this time and therefore there is no reason for a coupling connector CC to be connected to the charging connector CN. For example, the first duration d1 may be between 40 seconds and 80 seconds. As an illustrative example, the first duration d1 may be equal to 60 seconds. But other values ​​of the first duration d1 may be used.

[0068] Condition c3 is a condition of use intended to determine whether the vehicle V is currently traveling by considering the time elapsed since at least one seat belt (and in particular that of the driver) was locked. It will be understood that if the seat belts have been locked for a certain time, it is because the journey of the vehicle V began substantially since this time and therefore there is no reason for a coupling connector CC to be connected to the charging connector CN. For example, the second time d2 may be between 40 seconds and 80 seconds. As an illustrative example, the second time d2 may be equal to 60 seconds. But other values ​​of the second time d2 may be used.

[0069] Condition c4 is a location condition intended to determine whether the vehicle V is making a journey by considering the distance separating it from the nearest charging station having a known geographical position in a database. It will be understood that if the vehicle V is far from a charging station, there is no reason for a coupling connector CC to be connected to the charging connector CN. For example, the second threshold s2 may be between 50 meters and 150 meters. As an illustrative example, the second threshold s2 may be equal to 100 meters. But other values ​​of the second threshold s2 may be used.

[0070] Preferably, the four conditions cl to c4 are used. But this is not obligatory. Indeed, it is possible to use only one of the four conditions cl to c4, or at least two of these four conditions cl to c4. Furthermore, the list of conditions of use or current location of the vehicle V given above is not exhaustive.

[0071] Of course, the supervision computer CS or the monitoring device DS has access to all the information relating to each condition of use or location used in order to be able to determine whether the latter is satisfied.

[0072] Also for example, in sub-step 20 of step 10-50, when the driver wants the vehicle V to move and the central locking of the doors of the vehicle V is deactivated, it is also possible to activate the (for example the monitoring device DS can also trigger the activation of the) central locking of the doors. This option is intended to reinforce the safety of the vehicle V and its passengers, in particular when the vehicle V does not have an automated procedure for activating the central locking of its doors after the elapse of a predefined duration following the placement of the GMP in its second state (activated) or after the vehicle V has traveled a predefined distance.

[0073] Also for example, in sub-step 30 of step 10-50, when the driver wants the vehicle V to move, it is also possible (for example the monitoring device DS can also) to trigger the operation of at least one sound or light alert device of the vehicle V. This option is also intended to reinforce the safety of the vehicle V and its passengers, because it makes it possible to alert the people located in the environment of the vehicle V.

[0074] Also for example, in sub-step 30 of step 10-50, each sound or light warning device can be chosen from a light danger warning device (or "warning"), a sound alarm device (or system) against theft and / or intrusion, and a sound horn (or "horn").

[0075] Preferably, at least two sound or light alert devices are used, and even more preferably at least one sound alert device and at least one light warning device, because this offers complementarity, especially when the light intensity level is very low (or even zero). But this is not mandatory. In fact, only one sound or light warning device can be used. Furthermore, the list of sound or light warning devices given above is not exhaustive.

[0076] Also for example, and as illustrated non-limitingly in [Fig. 3], step 10-50 can also comprise a sub-step 40 in which it is possible (for example the monitoring device DS can) to trigger the stopping of the operation of each audible or luminous alert device put into operation after the disconnection of the coupling connector CC from the charging connector CN. It will be understood in fact that if this disconnection is effective, there is, a priori, no longer any risk of car-jacking, and therefore there is no longer any reason to alert the people located in the environment of the vehicle V.

[0077] It will also be noted, as illustrated non-limitingly in [Fig. 2], that the supervision computer CS (or the computer of the monitoring device DS) may also comprise a mass memory MM1, in particular for storing the current state of the GMP and the connection state of the charging connector CN, as well as any intermediate data involved in all its calculations and processing operations. Furthermore, this supervision computer CS (or the computer of the monitoring device DS) may also comprise an input interface IE for receiving at least the current state of the GMP, the connection state of the charging connector CN, the information relating to each condition of use or location used and the response of the driver, for use in calculations or processing operations, possibly after having formatted and / or demodulated and / or amplified them, in a manner known per se, by means of a digital signal processor PR2.In addition, this supervision calculator CS (or the calculator of the monitoring device DS) can also comprise an output interface IS, in particular to deliver a message asking the driver if he wishes to move the vehicle V (or a message triggering such a request), a message (or order) to deactivate (or reactivate) the immobilization procedure (or a message triggering such deactivation or reactivation), a message (or order) to trigger the central locking of the doors, or a message (or order) to trigger (or stop) the operation of an audible or luminous warning device.

[0078] It will also be noted that the invention also proposes a computer program product (or computer program) comprising a set of instructions which, when executed by processing means of the electronic circuit (or hardware) type, such as for example the processor PR1, is capable of implementing the monitoring method described above to detect in the land vehicle V a abnormal connection of a coupling connector to its CN charging connector.
