Description

Title of the invention: Seat positioning system for a motor vehicle technical field

[0001] The invention relates to a seat positioning system for a motor vehicle. The invention relates to such a system for modulating the volume of a luggage compartment extending behind the rear seats of the vehicle and / or behind the front seats of the vehicle. Previous technique

[0002] Motor vehicles are commonly known in which the volume of the luggage compartment located behind the rear seats can be adjusted by moving a rear seat and / or folding down a rear seat backrest. Generally, the seat movement(s) and / or folding(s) are performed manually by an individual. Such seat movements and / or folding are carried out through gradual, step-by-step adjustments to ensure that the free volume of the luggage compartment is sufficiently large to accommodate the luggage while preserving, as much as possible, the comfort of the passengers seated in the rear seats. These gradual, step-by-step adjustments are tedious and do not necessarily result in a situation that allows for optimal loading of the luggage, or worse, in a situation that prevents the luggage from being loaded.

[0003] The invention aims to overcome this drawback.

[0004] A system is also known from US2007 / 265754 in which an item to be loaded into a vehicle is identified by reading a barcode or RFID tag on the item, using a barcode or RFID tag scanner. The system queries an item database to determine the dimensions (height, length, and width) and weight of the item to be loaded, corresponding to the identifier read on the item. The system also queries a vehicle database to determine the vehicle size, space dimensions, and configuration available for loading. The system compares the dimensions of the item to be loaded with the available space dimensions and configuration and determines whether loading the item is possible.If the system determines that the item's dimensions are compatible with the available space and configuration for loading, the US2007 / 265754 system determines which seat configuration(s) are required to allow the item to be loaded into the vehicle. The system also determines... The system uses data from seat-related sensors—such as weight sensors or seatbelt sensors—to determine if the seats can be reconfigured. Based on this information, the system determines if a suitable seat configuration exists that would allow the item to be loaded into the vehicle's cargo area. If the system determines a possible seat configuration and seats are available for adjustment, the system sends a command to a seat control unit to adjust the seat configuration to allow the item to be loaded into the vehicle's cargo area.

[0005] The US2007 / 265754 system for adjusting the position of vehicle seats to allow the loading of a load is limited to loading such a load bearing a barcode or an RFID tag. The US2007 / 265754 system does not extend to loading any load that does not bear a barcode or an RFID tag. Nor does the US2007 / 265754 system extend to loading any load whose dimensions are not listed in a database accessible remotely via a wireless network.

[0006] The invention aims to overcome this drawback.

[0007] DE102015219059 is also known as a system for detecting the load status of a luggage compartment located behind the rear seats of a vehicle and for folding down the backrest of a rear seat when a predetermined capacity limit of the luggage compartment is reached during loading. The system of DE102015219059 further provides for conditioning the folding of the seat backrest on the situation in which the rear seat is unoccupied. The system of DE102015219059 includes a luggage compartment load status monitoring camera, located in the luggage compartment, which detects when a luggage compartment capacity limit is reached when a piece of luggage placed in the luggage compartment is resting against the backrest of the rear seat and the luggage is preventing the tailgate from closing.

[0008] The DE102015219059 system requires an attempt to load baggage into the baggage compartment to determine that the dimensions of the baggage intended for loading are incompatible with the dimensions of the baggage compartment. Since the bag is large and heavy, such an attempt to load it, which proves incompatible with the dimensions of the baggage compartment, is unnecessary and should be avoided. Furthermore, due to Because of this incompatibility, the DE102015219059 system requires the unloading of this baggage, which is itself superfluous.

[0009] The invention aims to overcome this drawback.

[0010] The invention therefore aims to provide a system allowing luggage to be loaded into a luggage compartment of a motor vehicle by an individual without requiring progressive step-by-step adjustments of the position and / or configuration of the seats limiting the luggage compartment.

[0011] The invention therefore aims to provide such a system allowing for easier luggage loading. Description of the invention

[0036] [Fig.4] [Fig.4] is a representation of a graphical interface of a system according to a particular embodiment of the invention,

[0037] [Fig. 5] [Fig. 5] is a block diagram of a particular embodiment of a method according to the invention for modulating the volume of a luggage compartment, and

[0038] [Fig.6] [Fig.6] is an illustration of a direct orthonormal XYZ coordinate system classically used in automotive design.

[0039] Figure 1 illustrates the technical scope of the invention. The motor vehicle 4, shown in rear view with the tailgate open, has a luggage compartment 2 in which luggage 6 of various types, volumes, and shapes is arranged. By way of illustration, the luggage 6 includes a windsurfing board 6, the dimensions of which, particularly its length, are generally incompatible with maintaining all the seats in the passenger compartment 14 of the vehicle 4.

[0040] In [Fig. 2], the automobile vehicle 4, the roof of which is not shown, includes a system 1 for modulating the volume of a luggage compartment 2 formed behind at least one seat 3 of a motor vehicle (4). The system 1 includes an infotainment unit 7 designed to provide individuals in the vehicle with information concerning vehicle characteristics and / or entertainment and / or satellite navigation information, and means for selecting this different information. The automobile vehicle 4 shown includes seats 3, 2 front seats and 3 rear seats, each equipped with actuators (not shown) designed to move seat 3 back and forth and back and forth along an axis substantially parallel to the X-axis of the direct orthonormal XYZ frame. Each front and rear seat 3 is equipped with an actuator of The system 1 of the invention is adapted to control the actuators 13 and modulate the volume of the luggage compartment 2, excluding the driver's seat (front left seat), whose positioning and configuration cannot be adjusted solely by the system 1 of the invention. It is also possible to provide that at least one seat—in particular, each seat—is equipped with an actuator for raising / lowering a seat cushion 3 along an axis parallel to the Z-axis of the XYZ coordinate system.

[0041] An example of modulating the volume of the luggage compartment 2 of a vehicle 4 according to the invention is shown in [Fig. 3]. In this example, a front right seat 3 is moved forward along an axis parallel to the X-axis of the right-handed orthonormal XYZ coordinate system. This movement is represented by arrow 15 in [Fig. 3]. In addition, the backrest of the front right seat 3 is tilted forward along an axis parallel to the Y-axis of the right-handed orthonormal XYZ coordinate system. This tilting is symbolized by arrow 16 in [Fig. 3]. Finally, the backrest of the rear right seat 3 is tilted forward along an axis parallel to the Y-axis of the right-handed orthonormal XYZ coordinate system. This tilting is symbolized by arrow 18 in [Fig. 3]. These adjustments made to the positioning and configuration of the seats 3 are controlled by the system 1 according to the invention and result from a single indication made by the individual on the infotainment unit 7.System 1 according to the invention controls the actuators 13 and monitors their synchronization to achieve the optimized volume of the luggage compartment 2.

[0042] A detail of an infotainment unit 7 of a system 1 according to the invention is shown in [Fig. 4]. The infotainment unit 7 comprises a screen with a plurality of touch-sensitive areas 8 adapted to allow an individual to provide instructions to the system to modulate the volume of a luggage compartment 2 formed behind at least one seat 3 of a motor vehicle 4 of the type comprising at least one actuator of at least one seat 3 limiting the volume of the luggage compartment 2 forward. A first touch-sensitive area 8 (A) is a pre-selection touch-sensitive area for entering at least one data point representative of the dimensions of the luggage to be loaded into the luggage compartment 2. Of course, the different touch-sensitive areas 8 shown simultaneously in [Fig. 4] can appear successively on the screen of the infotainment unit 7 depending on the selected option.A first option to provide representative data on the dimensions of the luggage, selectable by the touch zone 8 Al, is to choose a . Luggage type Ala, Alb, or Ale. Of course, the list of different luggage types is not exhaustive. For example, luggage type Ala could be a surfboard intended for loading in the luggage compartment(s). Selecting option Ala, corresponding to the surfboard loading plan, requires specific and appropriate modifications to the passenger compartment 14 of vehicle 4 by moving seats 3 and, if necessary, a parcel shelf of vehicle 4. Luggage type Alb could be a bicycle intended for loading in the luggage compartment(s). Selecting option Alb, corresponding to the bicycle loading plan, requires specific and appropriate modifications to the passenger compartment 14 of vehicle 4 by moving seats 3 and, if necessary, a parcel shelf of vehicle 4. Luggage type Aie could be a pair of skis intended for loading in the luggage compartment(s).Selecting the Aie option corresponding to the project of loading a pair of skis leads to a specific and appropriate arrangement of the passenger compartment 14 of the vehicle 4 by moving seats 3 and, where applicable, a rear shelf of the vehicle 4.

[0043] A second option for providing representative data on the luggage dimensions, selectable via touch-sensitive area 8 A2, consists of providing the dimensions A2x, A2y, and A2z of the luggage to be loaded into luggage compartment 2. The dimensions A2x, A2y, and A2z of the luggage extend along three directions orthogonal to each other. For example, touch-sensitive area 8 corresponding to A2x allows the largest dimension—in particular, the length—of the luggage to be entered; touch-sensitive area 8 corresponding to A2z allows the smallest dimension—in particular, the thickness or height—of the luggage to be entered; and touch-sensitive area 8 corresponding to A2y allows the intermediate dimension of the luggage to be entered. In this embodiment, system 1 according to the invention is a system for modulating the position and / or configuration of the seats in the vehicle according to the dimensions of the luggage provided to system 1.

[0044] A third option for providing data representative of the dimensions of the luggage, selectable by the touch zone 8 A3, consists of providing a predetermined combination of dimensions, the predetermined combination of dimensions being chosen from a plurality of predetermined combinations of dimensions, proposed by the infotainment unit 7 of system 1.

[0045] In a particular embodiment of a method according to the invention, shown in [Fig. 5], the dimensions of a piece of luggage 6, the loading of which into a luggage compartment 2 of a motor vehicle is envisaged, are provided by an individual to the system 1 according to the invention. The dimensions of the luggage are provided by the individual during a step 100 in which the individual interacts with a menu and submenus of an infotainment unit 7 of a motor vehicle 4. The individual interacts with touch-sensitive areas 8 of a screen on the infotainment unit 7 and provides system 1 with each of the length (z), width (x) and height or thickness (y) values ​​(x,y,z) of the bag 6. The user can enter each of the (x,y,z) values ​​on a keypad or select each value (x,y,z) from a drop-down menu, for example. After the user confirms the dimensions of the bag 6 on the infotainment unit 7, representative data of the dimensions (x,y,z) are transmitted 101 to an electronic device 9 of system 1, which receives this representative data and analyzes 102 each of the dimensions (x,y,z) of the bag 6 in comparison with the maximum capacity Vo of the baggage compartment 2.The "maximum capacity Vo" of luggage compartment 2 refers to the maximum volume that luggage compartment 2 can hold in a configuration where no seats 3 in vehicle 4 are occupied and the seats 3 are moved / configured to a minimum occupancy state. If any dimension (x, y, z) of luggage 6 exceeds the maximum (+) and / or acceptable capacity Vo of luggage compartment 2, system 1 activates initial alerting means 10 and informs the individual, via the infotainment unit 7, that at least one dimension of luggage 6 exceeds the maximum capacity Vo of luggage compartment 2. The system prompts the individual to modify the dimensions of luggage 6 or to manually adjust the volume of the luggage compartment and / or repack luggage 6.System 1 also activates a delay 10 in the volume modulation procedure of the luggage compartment 2, pending input of luggage dimensions (x, y, z) 6 that are compatible with the maximum capacity Vo of the luggage compartment 2. The alert means 10 may be visual alerts, displayed on the graphical interface 5 of the infotainment unit 7. The alert means 10 may also include audible alerts. When the dimensions (x, y, z) of the luggage 6 are compatible with the maximum capacity Vo of the luggage compartment 2, the electronic device 9 of system 1 analyzes 103 whether a modification to the configuration and / or positioning of at least one of the vehicle seats 4 needs to be made.When the dimensions (x, y, z) of baggage 6, intended for loading into luggage compartment 2 of vehicle 4, are compatible (-) with the capacity of luggage compartment 2, and no changes to the configuration and / or positioning of at least one of the seats 3 of vehicle 4 are required, system 1 prompts the individual to place baggage 6 in luggage compartment 2. When the dimensions (x, y, z) of baggage 6, intended for loading into luggage compartment 2 of vehicle 4, are not compatible (-) with the capacity of luggage compartment 2 but are compatible with the maximum and / or acceptable capacity Vo of luggage compartment 2, the device... 9 electronic system 1 receives data representative of a seat occupancy state 3 provided by occupancy sensors 11 and analyzes 104 whether one of the data representative of a seat occupancy state 3 opposes the modification of the configuration and / or positioning of at least one of the seats 3 of the vehicle 4. If one of the data representative of a seat occupancy state 3 opposes the modification of the configuration and / or positioning of at least one of the seats 3, system 1 activates (+) second means 12 of alert and indicates to the individual via the infotainment unit 7 which occupied seat 3 opposes the modulation of the volume of the luggage compartment 2 and invites the individual to modify the occupancy of the seats 3.If one of the data representing an occupancy state of a seat 3 opposes the modification of the configuration and / or positioning of at least one of the seats 3, the system 1 also activates a time delay 12 of the procedure for modulating the volume of the baggage compartment 2 while waiting for the reception of a data representing an unoccupied state of a seat 3 provided by the occupancy sensor 11. When no data representative of the occupancy status of a seat 3 prevents the modification of the configuration and / or positioning of at least one of the seats 3, the electronic device 9 of the system 1 transmits (-) a command to at least one actuator 13 of at least one seat 3 to modify 105 the positioning and / or configuration of at least one seat 3 so as to place the seat(s) in a predetermined spatial configuration in which the baggage 6 can be placed in the baggage compartment 2.

[0046] The method according to the invention, shown in [Fig. 5], allows a vehicle user to optimize the vehicle configuration according to their specific luggage needs. In certain embodiments not shown, the system 1 can offer, via a screen on the infotainment unit 7, predetermined configurations, each configuration corresponding to a luggage category, such as skis, a surfboard, a bicycle, or a crate / box of predefined dimensions. For example, by selecting the "surfboard" touch area on the screen of the infotainment unit 7, the user will instruct the system to move the front passenger seat forward, tilt the front passenger seat back forward, and fold down the rear passenger seat back, as shown in [Fig. 3].The corresponding adjustment of the volume of luggage compartment 2 allows the "surfboard" to be loaded on the right side (along an axis substantially parallel to the Y-axis of the direct orthonormal XYZ coordinate system) of luggage compartment 2 of vehicle 4. In this example, illustrating a particular embodiment of a method according to the invention, the system can indicate to the individual that the requested adjustment of the luggage compartment volume does not allow the front right seat to be occupied by a passenger. In this example, illustrating a... a particular embodiment of a process according to the invention, the system may also indicate to the individual that the "surfboard" must be moored.
