Description

Title of the invention: motor vehicle comprising a removable partition dividing the passenger compartment in two

[0001] The technical context of the present invention is that of passenger comfort in a motor vehicle, and in particular their thermal comfort. More specifically, the invention relates to a motor vehicle and a method for thermal pre-conditioning a motor vehicle passenger compartment. The present invention has a particularly advantageous, though not limiting, application in the field of electrified motor vehicles of the electric or hybrid type, whose propulsion is provided by an electric motor.

[0002] As is known, motor vehicles include heating and ventilation systems that ensure the thermal comfort of their occupants. Such heating and ventilation systems implement air circulation within the passenger compartment, the temperature of which is controlled upstream of the passenger compartment. Such heating and ventilation systems include, in particular:

[0003] - an air intake flap located at the front of the motor vehicle and allowing to bring outside air into the passenger compartment of the motor vehicle;

[0004] - a heating and air conditioning unit for setting and controlling a temperature of the air blown into the passenger compartment. The heating and air conditioning unit thus allows the air entering through the air intake flap to be cooled or heated before it is propelled into the passenger compartment;

[0005] - air extractors housed in the passenger compartment and allowing the stale air to be evacuated.

[0006] As is known, occupants of motor vehicles use such ventilation systems to be able to control thermal comfort in the passenger compartment, when they are present in the passenger compartment.

[0007] However, when starting a motor vehicle, thermal comfort is not always optimal, depending on the outside temperature, and it is necessary to wait several minutes before the passenger compartment heats up and the desired thermal comfort is achieved. Obviously, this uncomfortable situation is undesirable.

[0008] In order to enjoy optimal thermal comfort from the moment of entering the vehicle, thermal preconditioning is known, which allows the ventilation system to be remotely controlled to heat or cool the passenger compartment before entry. Thus, while the vehicle is still stationary and unoccupied, the ventilation system is activated to blow air into the passenger compartment at the desired temperature.

[0009] A known drawback of this remote thermal preconditioning is the high power consumption of the controlled ventilation system. As a result, such prolonged use significantly reduces the electrical energy stored in the vehicle's battery. In the case of a conventional internal combustion engine vehicle, prolonged use will be limited by the battery's capacity to supply such electrical energy, but it will still be possible to restart the vehicle. However, in the case of an electric or hybrid vehicle, prolonged use of thermal preconditioning reduces the vehicle's range.

[0010] Furthermore, known heating and ventilation systems lead to heating the entire passenger compartment, even when the vehicle is not occupied. Thus, in all cases, there is a need to reduce the energy impact of thermal preconditioning.

[0011] The present invention aims to provide a new motor vehicle in order to address at least largely the previous problems and to lead to other advantages.

[0012] Another objective of the invention is to limit the energy impact of thermal preconditioning.

[0013] Another objective of the invention is to optimize the thermal pre-conditioning of the passenger compartment of the motor vehicle.

[0014] According to a first aspect of the invention, at least one of the aforementioned objectives is achieved with a motor vehicle comprising:

[0015] - a passenger compartment comprising a first row of front seats and a second rear row of seats located behind the first row, relative to a longitudinal axis of the motor vehicle;

[0016] - a removable partition configured to be able to extend between the first row and the second row;

[0017] - a control device for the removable wall allowing the configuration of said wall removable partition between a first configuration, called deployed configuration, in which the removable partition extends between the first row and the second row so as to prevent air circulation between said first row and said second row, and a second configuration, called folded configuration, in which the removable partition is folded so as to allow air circulation between the first row and the second row.

[0018] In the context of the present invention, the transverse axis is understood as a direction taken between one lateral side of the motor vehicle and an opposite lateral side of said motor vehicle. In other words, the transverse axis is understood as a direction extending from a passenger side of the motor vehicle to a side driver of said motor vehicle, or vice versa. The adjectives lateral, inside, and outside refer to such a transverse axis. Furthermore, the longitudinal axis extends along a direction running from the front to the back or from the back to the front of the motor vehicle. The longitudinal axis is perpendicular to the transverse axis. The adjectives front, front, and rear refer to this longitudinal axis. Finally, the vertical axis is understood to be along an axis extending from the wheels of the motor vehicle to the roof of said motor vehicle, or vice versa, the vertical axis being simultaneously perpendicular to the transverse axis and the longitudinal axis. The adjectives above and below, or lower and upper, refer to this vertical axis.

[0019] In the context of the present invention, the motor vehicle may be of any type. In particular, the motor vehicle may be of the internal combustion type, that is, one in which a drivetrain is set in motion by an internal combustion engine coupled in rotation to said drivetrain. Alternatively, the motor vehicle may be of the electrified type. In the context of the invention, the electrified motor vehicle is of the type of an electric or hybrid motor vehicle. Generally, the drivetrain of such an electrified motor vehicle is set in rotation by an electric machine, electrically powered by an electric traction battery, in order to generate a motor torque used to set the motor vehicle in motion.In addition or alternatively, the electric machine is configured to recover mechanical energy from the traction chain and convert it into electrical energy, thereby producing a braking torque on said traction chain and allowing the electric traction battery to be recharged.

[0020] In the context of the present invention, the passenger compartment of the motor vehicle is a space within which a driver of the motor vehicle and, optionally, one or more occupants can be seated. The passenger compartment is delimited at the front by a windshield, at the rear by a trunk, and laterally by two opposing side walls.

[0021] In the context of the present invention, the first row of seats is the so-called row 1. This is the row of seats located directly behind the windshield, steering wheel, and dashboard of the motor vehicle. The first row of seats may include a driver's seat and a passenger seat, separate from the driver's seat, or a bench seat extending between the two opposite side walls.

[0022] In the context of the present invention, the second row of seats is the so-called row 2 of seats. It is the row of seats located behind the row of seats in row 1. The second row of seats may comprise several independent seats or a bench seat which extends between the two opposite side walls.

[0023] In the context of the present invention, the removable partition is a retractable partition which, when in its deployed configuration, extends between the first row and the second row, so as to partition the passenger compartment into two spaces independent of each other: a first space located between the windshield and the removable partition, thus encompassing the first row, and a second space located between the removable partition and a rear window of the passenger compartment, thus encompassing the second row.

[0024] In the context of the present invention, the control device takes the form of a hinge mechanism for the removable partition, allowing it to be configured in any position between the deployed and folded configurations. In the deployed configuration, the removable partition extends between the first and second rows, thus creating two independent spaces. In this configuration, it is easier to heat the portion of the passenger compartment located at the level of the first row, since the volume to be heated is smaller than if the removable partition were folded.

[0025] Thus, the motor vehicle conforming to the first aspect of the invention makes it possible to limit the energy impact of the thermal pre-conditioning of the passenger compartment.

[0026] The motor vehicle conforming to the first aspect of the invention advantageously comprises at least one of the improvements below, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0027] - the control device is motorized: it includes at least one actuator allowing the removable partition to be configured in any position between folded and deployed. This advantageous configuration allows for automatic control of the position and / or deployment of the removable partition. To this end, the motor vehicle advantageously includes a control unit configured to operate the actuator. The control unit is configured to be remotely controlled, thus making it possible to remotely control the deployment or folding of the removable partition without necessarily being present inside the motor vehicle;

[0028] - the removable partition extends inside the passenger compartment between two side walls opposite said passenger compartment. In other words, the removable partition extends from one lateral edge of the passenger compartment to the other, in order to close off a space located between the windshield of the motor vehicle and the removable partition, which includes the first row of seats. This advantageous configuration makes it possible to create a smaller volume that a heating and ventilation system of the motor vehicle will heat more quickly and while consuming less electrical energy to do so;

[0029] - the passenger compartment includes means for guiding the removable wall, the means for the guides being attached to at least one side wall of the passenger compartment. By way of non-limiting example, the guide means take the form of a guide rail forming a groove into which the removable partition is engaged at one of its lateral ends. This advantageous configuration also makes it possible to stiffen the removable partition between the two side walls of the passenger compartment;

[0030] - according to a first embodiment, the control device is integral of a roof pavilion of the passenger compartment. In this first variant of the embodiment, when the removable partition is deployed, it descends from the control device, relative to the vertical axis, towards a floor of the passenger compartment;

[0031] - according to a second embodiment, the control device is integral of a passenger compartment floor. In this second embodiment, when the removable partition is deployed, it rises from the control device, relative to the vertical axis, towards a passenger compartment roof panel;

[0032] - the control device comprises an axis of rotation around which the wall The removable panel is rolled up when configured in its folded position. Alternatively, the control device is configured to be able to fold the removable panel like an accordion;

[0033] - the actuator of the control device includes a motor configured to drive rotating the axis of rotation in order to unfold or fold the removable wall. In this embodiment, one end of the removable wall is fixed to the axis of rotation so that the rotation of the axis of rotation by the motor leads to a winding or unwinding of the removable wall;

[0034] - according to a first embodiment, the motor vehicle comprises a source of infrared, microwave, or ultraviolet radiation, the radiation source being configured to generate radiation towards the removable partition in order to heat it. This advantageous configuration makes it possible to heat the removable partition, thus facilitating the heating of the part of the passenger compartment located between the windshield and said removable partition;

[0035] - alternatively or complementaryly, according to a second embodiment, The axis of rotation includes a heating element configured to generate heat that is transferred to the removable wall. Advantageously, when the vehicle is electrified, the heating element is thermally coupled to the vehicle's traction battery. This configuration is particularly interesting and advantageous because it allows the heat produced by charging the traction battery to be used to transfer it to the removable wall, which, when deployed, actively contributes to heating the part of the passenger compartment containing the first row of seats.

[0036] - for this purpose, advantageously, the heating element is thermally coupled to the electric traction battery via a heat pipe, one end of which is thermally coupled to the electric traction battery and the other end of which is thermally coupled to the heating element. In this case, the heating element is advantageously the axis of rotation itself;

[0037] - advantageously, in the second embodiment, the device of The control unit includes an insulating housing that accommodates the removable panel when it is in its folded configuration. This advantageous configuration facilitates heating the removable panel within its insulating housing, the insulating housing then forming a thermal enclosure;

[0038] - the removable wall comprises a refractory material, such as for example a ceramic. This advantageous configuration allows for the temporary storage of thermal energy in the removable wall, preferably when said removable wall is in its folded configuration. In particular, and particularly advantageously, the heating of the removable wall is optimal when it is folded around the axis of rotation of the control device, the axis of rotation being the heating element;

[0039] - the removable wall comprises a reflective material, such as for example a metal. This advantageous configuration improves heating in the area of ​​the passenger compartment insulated by the removable partition, and directs an airflow propelled by the heating and ventilation system at dashboard level to bounce off the removable partition. Consequently, the heat carried by the airflow is not transferred, or is transferred to a lesser extent, to the removable partition;

[0040] - the refractory material is located on the side of the second row of seats, and the reflective material is located on the side of the first row of seats, when the removable partition is configured in its deployed configuration;

[0041] - when the removable partition is configured in its deployed configuration, then It forms an airtight partition that is 80% airtight between the first and second rows of seats. In other words, when the removable partition is fully deployed between the first and second rows, from the roof to the passenger compartment floor, it forms an 80% airtight partition between the first-row and second-row sections of the passenger compartment. In this configuration, at most 20% of the airflow from the dashboard heating and ventilation system passes through the removable partition on the second-row side.

[0042] - the motor vehicle includes at least one air extractor located between the The first row of seats and the removable partition. This advantageous configuration allows stale air to be evacuated from the part of the passenger compartment located at the level of the first row of seats, when the removable partition is configured in its deployed configuration;

[0043] - at least one air extractor is located near the roof lining of the passenger compartment. Generally speaking, at least one extractor is located high up, at the level of an upper part of the passenger compartment;

[0044] - at least one air extractor is configured in an open configuration allowing air to be extracted from the passenger compartment to the outside of the motor vehicle when the removable partition is configured in its deployed configuration.

[0045] According to a second aspect of the invention, a method for thermal preconditioning of a motor vehicle passenger compartment is proposed, conforming to the first aspect of the invention or to any one of its improvements, the thermal preconditioning method comprising the following steps:

[0046] - a heating step of the removable wall;

[0047] - a step of deploying the removable wall;

[0048] - a step of activating heating and ventilation of the passenger compartment at the level from the first row of seats.

[0049] The thermal preconditioning process according to the second aspect of the invention is preferably implemented when the motor vehicle has not yet started, that is to say when the engine - thermal or electric - is not yet rotating.

[0050] The heating step of the removable wall is preferably carried out when the removable wall is configured in its folded position. Conversely, when the removable wall is configured in its deployed position, the heating step preferably ends. Optionally, the heating step continues during the deployment step and / or when the removable wall is deployed.

[0051] In the context of the present invention, the heating step may be of the type of a heat generation step at or near the removable wall; or the heating step may be of the type of a heat transfer step of heat produced elsewhere on the motor vehicle, for example at the electric traction battery during its charging, and conveyed to and at the removable wall so that said heat is transferred to said removable wall.

[0052] The thermal preconditioning process according to the second aspect of the invention advantageously comprises at least one of the following improvements, the technical characteristics forming these improvements being able to be taken alone or in combination:

[0053] - the thermal preconditioning process includes an opening step at least one air extractor located between the first row of seats and the removable partition. The opening step is a continuation of the deployment and / or The step of activating the heating and ventilation in the passenger compartment of the motor vehicle. More generally, the opening step is carried out when the removable partition is configured in its deployed configuration. Conversely, when the removable partition is configured in its folded configuration, then the preconditioning process includes a closing step of at least one air extractor;

[0054] - the thermal preconditioning process includes a recharging step of a electric traction battery, the heating stage comprising a thermal coupling stage of the removable wall with the electric traction battery;

[0055] - Alternatively or in addition, the heating step includes a step of piloting a heating element, the heating element being of the type of a heating resistance thermally coupled with the axis of rotation of the control device of the removable wall, or the heating element being of the type of an ultraviolet, microwave or infrared radiation source configured to emit such radiation in the direction of the removable wall.

[0056] Various embodiments of the invention are provided, incorporating, according to all their possible combinations, the different optional features set out here.

[0057] Other features and advantages of the invention will become apparent from the following description on the one hand, and from several illustrative and non-limiting examples of embodiments given with reference to the accompanying schematic drawings on the other hand, in which:

[0061] [Fig.4] illustrates a synoptic view of the preconditioning process of a passenger compartment of the motor vehicle according to the first aspect of the invention.

[0062] Of course, the features, variants, and different embodiments of the invention can be combined in various ways, provided they are not incompatible or mutually exclusive. In particular, variants of the invention may be conceived comprising only a selection of features, described hereafter in isolation from the other described features, if this selection of features is sufficient to to confer a technical advantage or to differentiate the invention from the prior art.

[0063] In particular, all the variants and all the embodiments described are combinable with each other if nothing prevents this combination from a technical point of view.

[0064] In the figures, the elements common to several figures retain the same reference.

[0065] In the context of the present invention, the transverse axis Y is understood as a direction between one lateral side of the motor vehicle 1 and an opposite lateral side of said motor vehicle 1. In other words, the transverse axis Y is understood to be a direction extending from a passenger side of the motor vehicle 1 to a driver's side of said motor vehicle 1, or vice versa. The adjectives lateral, inside, and outside refer to such a transverse axis Y.

[0066] Furthermore, the longitudinal axis X extends as if taken along a direction extending from front to rear or rear to front of the motor vehicle 1. The longitudinal axis X is perpendicular to the transverse axis Y. The adjectives front, front and rear refer to this longitudinal axis X.

[0067] Finally, the vertical axis Z is understood as being taken along an axis which extends from the wheels of the motor vehicle 1 and towards the roof of said motor vehicle 1, or vice versa, the vertical axis Z being simultaneously perpendicular to the transverse axis Y and to the longitudinal axis X. The adjectives above and below, or lower and upper, refer to this vertical axis Z.

[0068] With reference to FIGURES 1 to 4, the invention addresses a motor vehicle 1 comprising:

[0069] - a passenger compartment 14 comprising a first row 141 of front seats and a second row 142 of rear seats located behind the first row 141, relative to a longitudinal axis X of the motor vehicle 1;

[0070] - a removable partition 19 configured to be able to extend between the first row 141 and the second row 142;

[0071] - a control device 18 for the removable wall 19 allowing the configuration of said removable partition 19 between a first configuration, called deployed configuration, in which the removable partition 19 extends between the first row 141 and the second row 142 so as to prevent air circulation between said first row 141 and said second row 142, and a second configuration, called folded configuration, in which the removable partition 19 is folded so as to allow air circulation between the first row 141 and the second row 142.

[0072] FIGURES 1 and 2 illustrate the removable wall 19 in a deployed configuration while [Fig.3] illustrates the removable wall 19 in a folded configuration.

[0073] In the embodiment illustrated in FIGURES 1 and 2, the removable partition 19 is deployed behind the first row 141 of seats, at the level of a central pillar of the motor vehicle 1, so as to create two independent spaces. In this configuration, it is then easier to heat the part of the passenger compartment 14 located at the level of the first row 141 since the volume to be heated is then smaller than if the removable partition 19 were folded down.

[0074] The removable partition 19 thus forms a retractable partition which, when in its deployed configuration, extends between the first row 141 and the second row 142, so as to partition the passenger compartment 14 into two spaces distinct from each other: a first space located between the windshield 13 and the removable partition 19, thus encompassing the first row 141, and a second space located between the removable partition 19 and a rear window 131 of the passenger compartment 14, thus encompassing the second row 142.

[0075] Advantageously, the removable wall 19 extends inside the passenger compartment 14 between two opposite side walls of said passenger compartment 14.

[0076] The control device 18 is attached to a roof panel 11, so as to allow the removable partition 19 to descend towards a floor 12 of the passenger compartment 14 when said removable partition 19 is configured in its deployed position. The control device 18 takes the form of a hinge mechanism for the removable partition 19, allowing it to be configured in any position between the deployed and folded positions.

[0077] The control device 18 is motorized: it includes at least one actuator for configuring the removable partition 19 in any configuration between the folded and deployed configurations. For this purpose, the motor vehicle 1 advantageously includes a control unit configured to drive the actuator and to be remotely controlled, thus making it possible to remotely control the deployment or folding of the removable partition 19.

[0078] As shown in [Fig. 4], the control device 18 includes a rotation axis 182 around which the removable wall 19 is wound when it is configured in its folded position. The actuator of the control device 18 includes a motor configured to drive the rotation axis 182 in order to deploy or fold the removable wall 19. [Fig. 4] illustrates the removable wall 19 in its folded position: the control device 18 includes an insulating housing 181 that contains the removable wall 19 when it is configured in its folded position. Thus, in the embodiment illustrated in [Fig. 3], the removable wall 19 is wound around its rotation axis 182 and housed in the insulating housing 181.

[0079] In order to allow for a faster temperature rise and to improve the thermal comfort of the passenger compartment 14, and in particular of the part of the passenger compartment 14 located at at the level of the first row 141, the control device 18 includes a heating element configured to be able to transmit HT calories to the removable wall 19.

[0080] In particular, the heating element is configured to allow heating of the removable wall 19 at least when it is in its folded configuration, and possibly when it is in its deployed configuration.

[0081] The heating element can be of the active type, i.e. a heat generator, or of the passive type, i.e. a heat transport vector towards the removable wall 19.

[0082] In the case where the heating element is of the active type, then it can take the form of a thermal radiation source, such as, for example, an ultraviolet source, an infrared source, or a microwave source. Such a thermal radiation source is configured to generate such thermal radiation inside the insulating housing 181 when the removable wall 19 is in its folded position.

[0083] Alternatively or complementaryly, when the heating element is of the active type, then it can take the form of a heating resistance coupled to the axis of rotation 182 and / or to the insulating housing 181 in order to generate HT calories which will be transmitted, by conduction or by convection or by radiation, to the removable wall 19.

[0084] In the case where the heating element is of the passive type, then it takes the form of a thermally conductive material coupled, on the one hand, to a heat source external to the control device 18 and, on the other hand, to the control device 18 and / or to the removable wall 19. Advantageously, the heating element is housed in the axis of rotation 182 or is formed by the axis of rotation 182, or is thermally coupled with the axis of rotation 182.

[0085] Advantageously, when the motor vehicle 1 is of the electrified type, the heating element is thermally coupled to an electric traction battery of the motor vehicle 1. If the control device 18 is housed in the floor 12 of the motor vehicle 1, then the thermal coupling between the heating element of the control device 18 and the electric traction battery—generally housed under the floor 12—can be direct, for example by thermal conduction through said floor 12, or indirect via a thermal conductor. Conversely, if the control device 18 is housed in the roof lining 11 of the passenger compartment 14, then the thermal coupling between the heating element of the control device 18 and the electric traction battery is indirect.For this purpose, the heating element is for example thermally coupled to the electric traction battery via a heat pipe, one end of which is... is thermally coupled to the electric traction battery and a second end of which is thermally coupled to said heating element.

[0086] It is thus possible to facilitate the heating of the removable wall 19 within its insulating housing 181, said insulating housing 181 then forming a thermal enclosure. Consequently, when the removable wall 19 is configured in its deployed position, the removable wall 19 can thus radiate and dissipate the stored high-temperature heat towards the part of the passenger compartment 14 located behind the windshield 13.

[0087] For this purpose, the removable partition 19 comprises:

[0088] - a refractory material, such as for example a ceramic, in order to be able to store temporarily heats the removable wall 19, particularly when the removable wall 19 is folded into the insulating housing 181. The refractory material is located on the side of the second row 142 of seats when the removable wall 19 is in its deployed configuration;

[0089] - a reflective material, such as for example a metal, in order to be able to reflect in Windshield 13 directs a flow of air propelled by a heating and ventilation system 16 to the dashboard. The reflective material is located on the side of the first row 141 of seats when the removable partition 19 is in its deployed configuration.

[0090] In addition, to improve the operation of the ventilation and heating of the passenger compartment 14, which is partitioned by the removable partition 19, outside air entering the vehicle 1 through an air inlet 17 located on the front 15 of the vehicle 1 is routed to the heating and ventilation system 16 where it is heated before being blown into the passenger compartment 14, forming an airflow FL towards the deployed removable partition 19. The vehicle 1 advantageously includes an air extractor located between the windshield 13 and the removable partition 19 to allow for the evacuation of stale air when the passenger compartment 14 is partitioned by the deployed removable partition 19.

[0091] The extractor is located high up, at the level of an upper part of the passenger compartment 14. The air extractor is configured in an open configuration allowing air to be extracted from the passenger compartment 14 to the outside of the motor vehicle 1 when the removable partition 19 is configured in its deployed configuration.

[0092] With reference to [Fig. 5], the invention also relates to a thermal preconditioning method 2 for a passenger compartment 14 of a motor vehicle 1 as described above, the thermal preconditioning method 2 comprising the following steps:

[0093] - a heating step 22 of the removable wall 19;

[0094] - a deployment step 23 of the removable wall 19;

[0095] - an activation step 25 of a heating and ventilation system for the passenger compartment 14 first row level 141 seats.

[0096] The heating step 22 of the removable wall 19 is preferably carried out when the removable wall 19 is configured in its folded position. Conversely, when the removable wall 19 is configured in its deployed position, then the heating step 22 preferably ends. Optionally, the heating step 22 continues during the deployment step 23 and / or when the removable wall 19 is deployed.

[0097] In the context of the present invention, the heating stage 22 may be of the type of a high-temperature (HT) heat generation stage at or near the removable wall 19; or the heating stage 22 may be of the type of a heat transfer stage of HT heat produced elsewhere on the motor vehicle 1, for example at the electric traction battery during its charging, and conveyed to and at the removable wall 19 so that said HT heat is transferred to said removable wall 19.

[0098] The thermal preconditioning process 2 includes an optional opening step 24 – shown in dashed lines in [Fig. 5] – of the air extractor located between the first row 141 of seats and the removable partition. The opening step 24 is a consequence of the deployment step 23 and / or the activation step 25 of the heating and ventilation in the passenger compartment 14 of the motor vehicle 1, when the removable partition 19 is configured in its deployed configuration. Conversely, when the removable partition 19 is configured in its folded configuration, the preconditioning process includes a closing step of at least one air extractor.

[0099] When the motor vehicle 1 is of the type of an electrified vehicle, the thermal preconditioning process 2 includes a charging step 21 - optional and represented in dotted lines on the [Fig.5] - of an electric traction battery, the heating step 22 including a thermal coupling step of the removable wall 19 with the electric traction battery.

[0100] In summary, the invention relates to the implementation of a removable partition 19 extending between a first row 141 of seats and a second row 142 of seats in a passenger compartment 14 of a motor vehicle 1, thereby dividing said passenger compartment 14 into two smaller spaces, thus facilitating their temperature control.
