The invention further relates to a chassis comprising such an arrangement. The invention further relates to a vehicle comprising such a chassis or such an arrangement.
[0002] A vehicle, particularly a motor vehicle, generally includes an internal combustion engine. Such an internal combustion engine, when in operation, emits nitrogen oxides commonly known as NOx. Such NOx emissions are generally measured at the internal combustion engine and / or at the exhaust system of such an internal combustion engine. These measurements, generally taken by a sensor, are interpreted in an electronic control unit in order to modify the parameters of such an engine based on the results of these measurements, in particular to reduce such NOx emissions. Such an electronic control unit is generally located near such an exhaust system.
[0003] However, such an exhaust system is located at the bottom of the chassis of such a vehicle, meaning that such a control unit is also located under the body. Now, an electronic control unit is not completely watertight, which is problematic when driving through deep puddles, and / or in floods that extensively cover the roadway, and / or when fording streams.
[0004] The objective of the present invention is to overcome the above drawbacks. In addition, the invention makes it possible to use a first support for the attachment of a first electronic control unit connected to a first sensor and a second support, identical to the first support, for the attachment of a second electronic control unit connected to a second sensor.

[0024] The direction in which a vehicle, particularly a motor vehicle, moves in a straight line is defined as the longitudinal direction X. By convention, the direction perpendicular to the longitudinal direction, located in a plane parallel to the ground, is called the transverse direction Y. The third direction, perpendicular to the other two, is called the vertical direction Z. Thus, a right-handed coordinate system XYZ is used in which X is the longitudinal direction in the front-to-back direction of the vehicle, i.e., directed towards the rear, Y is the transverse direction directed to the right, and Z is the vertical direction directed upwards. The forward direction corresponds to the direction in which the vehicle usually moves in the longitudinal direction and is opposite to the backward direction.
[0025] As illustrated in [Fig.1], a vehicle, preferably a motor vehicle 1, comprises a chassis or body 80. The vehicle 1 comprises a powertrain 86 including at least one heat engine or internal combustion engine 85.
[0026] The internal combustion engine 85 is, for example, arranged transversely. In this case, the vehicle 1 is preferably driven in traction, that is to say, the wheels front which are driving. The powertrain 86 then includes, for example, a mechanical or automatic gearbox 88.
[0027] Alternatively, the internal combustion engine 85 is arranged longitudinally. Preferably, the powertrain 86 includes a mechanical gearbox 88. In this case, preferably, the vehicle 1 is driven in rear-wheel drive, i.e., the rear wheels are driven.
[0028] Optionally, an additional electric motor 70 is provided in addition to the internal combustion engine 85. In this case, the vehicle 1 is a hybrid and preferably includes a battery 87 for storing electrical energy.
[0029] The vehicle 1, or chassis 80, comprises an arrangement 2. The arrangement 2 comprises at least one front longitudinal member 3. As illustrated in Figures 2 and 3, the arrangement 2 further comprises at least one cross member 4. Advantageously, the cross member 4 is arranged at the rear of the vehicle, at least at or behind a front row 90 of seat(s) including, for example, a driver's seat (see [Fig.1]).
[0030] As illustrated in [Fig. 4], the front longitudinal member 3 is preferably arranged on the right. The arrangement 2 further includes a first support 10 and a second support 10.
[0031] The first and second supports 10 are identical. Thus, the terms "first support" and "second support" serve only to differentiate them. In the following description, the first support is arranged at the front or substantially at the front of the vehicle and the second support is arranged at the rear or substantially at the rear of the vehicle.
[0032] The vehicle 1, or the arrangement 2, comprises a first electronic control unit or computer 30 and a first NOx sensor 50 (illustrated schematically in [Fig. 1]). The first bracket 10 is intended to secure the first electronic control unit 30 to the first NOx sensor 50. The first bracket 10 is fixed to the front side member 3. The first electronic control unit 30 is connected via a cable, wiring, or one or more wires 6 to the first sensor 50. The first sensor 50 is capable of measuring a level or value of nitrogen oxides at the internal combustion engine 85, for example at a cylinder head, or at least at the beginning of an exhaust line 7.
[0033] The vehicle 1, or the arrangement 2, comprises a second electronic control unit 40 and a second NOx sensor 60, as illustrated in [Fig. 5]. The second bracket 10 is intended to secure the second electronic control unit 40 to the second NOx sensor 60. The second sensor 60 is capable of measuring the level or value of nitrogen oxides (NOx) at the exhaust line 7 of the internal combustion engine 85. The second bracket 10 is fixed to the crossmember 4. The second electronic control unit 40 is connected via a cable, wiring, or one or more wires 6 to the second sensor 60.
[0034] Preferably, as illustrated in [Fig. 4], the first support 10 is fixed to the top of the side member 3. To this end, preferably, the front side member 3 comprises two threaded rods 8 extending vertically from an upper face 38. The upper face 38 of the side member 3 preferably extends in a transverse and longitudinal plane. To secure the first support to the side member with the two threaded rods 8, the support 10 comprises two holes 18, illustrated in particular in [Fig. 6]. Thus, each hole 18 of the first support is passed through by a threaded rod 8 of the spar 3 to ensure the pre-holding of the first support 10 on the spar 3. Nuts 37 cooperating with the threaded rods 8 ensure the holding of the first support 10 in position relative to the spar 3. The support 10 is then sandwiched between the upper face 38 of the spar 3 and the underside of the nuts 37 cooperating with the threaded rods 8.
[0035] In the embodiment of the arrangement 2 illustrated in [Fig. 2], the second support 10 is fixed to the top of the cross member 4. Preferably, the cross member 4 includes a threaded rod 49 extending vertically from an upper face 48 of the cross member. The upper face 48 of the cross member 4 preferably extends in a transverse and longitudinal plane. To secure the second support to the cross member with the threaded rod 49, the support 10 includes a hole 47, illustrated in particular in Figures 5 and 6. Thus, the hole 47 of the support is passed through by the threaded rod 49 of the cross member 4 to provide pre-positioning of the second support 10 on the cross member 4, as illustrated in [Fig. 2]. A nut cooperating with the threaded rod 49 secures the second support 10 in position relative to the cross member 4.The support 10 is then sandwiched between the upper face 48 of the cross member 4 and the underside of the nut (not shown) cooperating with the threaded rod 49. In this embodiment, the support 10 extends substantially vertically, the largest dimension of the support 10 extending transversely or substantially transversely.
[0036] In a variant of the embodiment of the arrangement 2 illustrated in [Fig. 3], the second support 10 is also fixed to the top of the cross member 4. Preferably, the cross member 4 includes a threaded rod 49 extending vertically from an upper face 48 of the cross member 4. The upper face 48 of the cross member 4 preferably extends in a transverse and longitudinal plane. To secure the second support to the cross member with the threaded rod 49, at least one of the holes 18 of the support 10 illustrated in particular in [Fig. 6] is used. Thus, the hole 18 in the support is passed through by the threaded rod 49 of the cross member 4 to ensure the pre-fixing of the second support 10 on the cross member 4. A nut 37 cooperating with the threaded rod 49 secures the second support 10 in position relative to the cross member 4. The support 10 is then sandwiched between the upper face 48 of the cross member 4 and the below the nut 37 cooperating with the threaded rod 49. Optionally, a second threaded rod 49 extends from the cross member 4 and cooperates with the second hole 18 of the support and a nut 37 completes the fixing of the second support 10 on the cross member 4. In this variant of the embodiment, the support 10 extends substantially vertically, the largest dimension of the support 10 extending longitudinally or substantially longitudinally.
[0037] More specifically, as illustrated in particular in [Fig. 6], a support 10 includes a receiving face 11 for an electronic control unit. By receiving face 11 is meant a face of the support 10 intended to face the electronic control unit that the support receives. For example, this receiving face 11 is flat or substantially flat. For example, the receiving face 11 is drilled, perforated, open, or cut out, i.e., it includes an opening 115. Such a cutout 115, preferably through the support, allows, for example, to contribute to, facilitate, or participate in the positioning and / or maintaining in position of the electronic control unit relative to its support. Advantageously, the second support 10, fixed to the cross member 4, has its receiving face 11 extending vertically or substantially vertically, as illustrated in Figures 2 and 3.
[0038] Preferably, the receiving face 11 of the first support 10 extends vertically and longitudinally over the longitudinal member 3, as illustrated in [Fig.4].
[0039] As a reminder, the first and second supports are completely identical. In other words, in the disassembled state, it is impossible to distinguish the first support from the second support.
[0040] Each support is, for example, shaped to protect the electronic control unit that it allows to be fixed, received, housed. Preferably, as illustrated in particular in Figures 2, 4, and 5, the support has substantially the overall shape of an open parallelepiped box. Thus, preferably, a support 10 comprises at least one extension 16. Advantageously, the support 10 comprises two extensions 16 extending parallel to each other as illustrated in [Fig. 6]. For example, the two extensions 16 extend perpendicularly with respect to the receiving face 11. In addition, the two extensions 16 extend from the side of the receiving face 11. At least one extension 16, preferably both extensions 16, each include a fastening means 27 for a hook 26. The hook 26 holds, supports, retains the cable 6 entering or exiting the electronic control unit attached to the support.For example, the fixing means 27 is a hole and the hook 26 clips, clips, wedges into the hole 27. Preferably, the support 10 also includes a lower wall 21. As illustrated in figures 2 and 4, the lower wall 21 extends in a transverse and longitudinal plane, . or substantially transverse and longitudinal. As illustrated in [Fig. 6], the lower wall 21 extends perpendicularly from the receiving face 11 and on the same side as the receiving face. Preferably, the support 10 also includes an upper wall 22. The upper wall 22 extends in a transverse and longitudinal plane, or substantially transverse and longitudinal. As illustrated in [Fig. 6], the upper wall 22 extends perpendicularly from the receiving face 11 and on the same side as the receiving face. Thus, preferably, the upper and lower walls 21, 22 are parallel to each other, facing each other. The extensions or walls 16 are parallel to each other so that these four walls (two walls 16, the lower wall 21, and the upper wall 22) or portions of the support, together with a fifth wall 25, form an overall parallelepiped shape lacking one wall.The wall 25 comprises on one side the receiving face 11 and on the other side the secondary face 15. Thus, this sort of open parallelepiped allows the electronic control unit to be housed via the missing wall or opening, while the five walls or portions of wall protect the control unit.
[0041] Preferably, the support 10 is made of folded and / or stamped sheet metal. For example, the sheet metal is made of steel or aluminum alloy. For example, the thickness of the sheet metal, and / or of each wall, is between 0.5 mm and 2 mm. Optionally, one or more folded edges, and / or one or more stamped edges, and / or one or more ribs 24 are provided so as to stiffen the support without adding material, and consequently with a constant and optimized mass.
[0042] As illustrated in particular in [Fig. 6], the receiving face 11, i.e., the fifth wall 25, includes at least one hole 12. Alternatively, or in addition, the fifth wall 25 includes at least one threaded rod 13 extending perpendicularly from the receiving face 11. Thus, the hole or holes 12, for example two as illustrated, and / or at least one threaded rod 13 contribute to the positioning and / or holding in position of at least one first model, or at least one second model of electronic control unit. The first model of electronic control unit differs here from the second model of electronic control unit, in particular in terms of fixing points and / or in terms of shape, and / or in terms of mass. Optionally, the support can position and hold more than two types or models of electronic control unit.In other words, the support, equipped with its holes 12, advantageously threaded or including attached nuts 17 behind, for example (see [Fig. 3]), and / or equipped with at least one threaded rod 13, is suitable for supporting various types or models of electronic control units. Such models of electronic control units may have similar shapes and / or features. differences in shape. In any case, the support is compatible to support different electronic control units.
[0043] Advantageously, on a given vehicle, the electronic control unit fixed to the support, itself fixed to the front longitudinal member, is the same electronic control unit as that fixed to the support, itself fixed to the rear crossmember.
[0044] Possibly, given the ability to fix several types of electronic control units on the support, the electronic control unit arranged at the front of a vehicle may be different from that arranged at the rear of the same vehicle.
[0045] As illustrated in [Fig. 3], the support 10 includes a retaining means 14 extending from the secondary face 15 of the fifth wall 25. In other words, the face opposite the receiving face 11 includes a retaining means 14. Preferably, the retaining means 14 is a hook or equivalent that helps to secure wiring 5 for the internal combustion engine 85 and / or for an electric motor 70. Alternatively, the retaining means 14 can be used to secure something other than wiring or an equivalent. For example, the fifth wall 25 includes a hole into which the retaining means 14 is clipped.
[0046] Preferably, the support 10 further includes a fastening means 19. For example, as illustrated in Figures 4 and 6, the fastening means 19 is a threaded rod extending from the upper wall 22, preferably perpendicularly upwards from this wall 22. The fastening means 19 then allows direct cooperation, or cooperation via a collar-type element, for example, with a grounding braid 9 connected to the electric motor 70. Advantageously, the grounding braid 9 is electrically insulated and / or the collar-type element is electrically insulated so as not to transmit any possible electrical discharge to the electronic control unit 30 supported within the support 10.
[0047] In summary, the solution comprises two identical supports for mounting two electronic control units or computers, each connected to a nitrogen oxide (NOx) measurement sensor for emissions from an internal combustion engine. Preferably, the first sensor 50 is positioned in the immediate vicinity of the engine 85, for example, on or near a cylinder head, while the second sensor 60 is positioned on the exhaust manifold or line 7. Each sensor 50, 60 measures the nitrogen oxides present in the exhaust gases from the internal combustion engine 85. The first sensor 50 takes NOx measurements at the outlet of the engine 85, and the data is transmitted to the first computer 30 via, for example, one of the cables 6 ([Fig. 4]). The second sensor 60 takes NOx measurements in the exhaust line 7, and the data is transmitted to the control unit 40 via one of the cables 6. As mentioned previously, one of the cables A cable or wire or braid 6 connects a sensor 50, 60 to its respective control unit 30, 40 so as to transmit the information from the sensor 50, 60 to the corresponding control unit. For example, another electrical cable or wire or braid 6, including a power supply, extends from the control unit to a power source if necessary. As illustrated in [Fig. 5], the cable 6 on the right side is held relative to the bracket 10 by means of a hook 26 preferably attached to an extension or tab 16 of the bracket 10. The cable 6 on the left side is held relative to the bracket 10 by means of another hook 26 preferably attached to the other extension or tab 16 of the bracket 10. In other words, the control unit bracket 10 for nitrogen oxides allows the power supply wiring harness to be attached to the control unit.
[0048] Advantageously, each support is arranged both at the front and the rear so that each computer is substantially vertical, i.e., in a vertical position. For example, as illustrated in [Fig. 5], a computer has an overall parallelepiped shape and comprises a connection interface 43 on a first face 41 (shown schematically in dashed lines) and another connection interface 44 on a second face 42 (shown schematically in dashed lines) opposite the first face 41 of the parallelepiped. Each connection interface 43, 44 is designed to cooperate with a lug, socket, or plug connected to each wire 6. Thus, the support extends so that the first and second faces 41, 42 of a computer extend vertically or substantially vertically.
[0049] In other words, through this support, the NOx calculator has its probe in a vertical position.
[0050] Furthermore, this support preferably includes other functions. As illustrated in particular in Figures 3, 4, and 6, the fastening means 19 (threaded rod extending from the upper wall 22 of the support) creates a fixed point, a fixing, for the grounding braid 9 in the case of an electric motor 70 equipping the vehicle 1. It should be noted that an extra length of grounding braid 9 is provided between the electric motor and the fastening means 19 because the electric motor is mobile relative to the body. Indeed, damping means are provided between the body and the electric motor. However, the means 19 is fixed relative to the body since the support 10 is directly mounted on the side member 3.
[0051] Furthermore, as illustrated in [Fig. 3], the support 10 can also serve to secure the motor wiring 5. For this purpose, as mentioned previously, the retaining means 14 is provided. It should be noted that the motor wiring then passes against, or substantially against, the secondary face 15 of the fifth wall 25 of the support.
[0052] Note that each of these functions can be provided for the support arranged at the front and / or for the support arranged at the rear.
[0053] For example, according to the embodiment of vehicle 1 partially illustrated in [Fig. 2], the crossmember 4 at least partially supports the gearbox 88 (not shown in this figure). In this case, the control unit is fixed to the crossmember supporting the gearbox, in the underbody area. Preferably, the internal combustion engine 85 is then arranged longitudinally. Thus, the support 10 is mounted on a very rigid crossmember 4, preferably via at least the threaded rod 49 (for example, welded to the crossmember 4), and cooperating in the hole 47 of the support 10. Preferably, in this case, the support 10 extends substantially transversely, that is, substantially parallel to the crossmember 4. As a result, the electronic control unit or control unit 40 also extends mainly in this direction.A first interface for connecting to the ECU is then arranged on the left, and a second interface for connecting to the ECU is then arranged on the right. The opening (absence of one of the six walls) of the support, which is roughly parallelepiped-shaped, is oriented towards the rear. This opening allows for the mounting and assembly of the ECU onto the support. Alternatively, the support could be oriented differently, for example, with the opening facing forward.
[0054] For example, in [Fig. 3], according to one embodiment of the vehicle 1, the crossmember 4 does not support the gearbox 88, the engine 85 being arranged transversely in the engine compartment at the front (not shown in this figure). Thus, the bracket 10 is mounted on the crossmember 4, preferably via at least one threaded rod 49 (for example, welded to the crossmember 4), and cooperating in at least one hole 18 of the bracket 10. Preferably, in this case, the bracket 10 extends substantially longitudinally, i.e., substantially perpendicular to the crossmember 4. As a result, the electronic control unit or computer 40 extends substantially longitudinally.A first connection interface to the ECU is then positioned approximately at the front of the crossmember, and a second connection interface is positioned approximately at the rear of the crossmember, particularly if the bracket is approximately centered above the crossmember in the front-to-rear direction. Indeed, as illustrated, the bracket 10 has a roughly parallelepiped-shaped box with an internal volume greater than the volume occupied by an ECU, preferably greater than the volume occupied by an ECU equipped with at least two connections. Thus, the bracket can act as a protective element for the ECU. As a reminder, the bracket is preferably made of metal. For example, the ECU has a plastic casing, which is therefore more fragile. Furthermore, the extensions 16 enhance this protection while ensuring optimal support for the cable(s) 6, as mentioned previously.The opening (absence of one of the six walls) of the support is then oriented. to the right, particularly if the exhaust line 7 extends along the right side of the vehicle, to facilitate assembly and connections, and / or subsequent disassembly if necessary. Alternatively, the bracket opening could be oriented to the left.
[0055] As illustrated in [Fig.4], the first computer 30 connected to the first nitrogen oxide sensor 50 is fixed in the engine compartment of the vehicle 1, on the front frame rail, preferably the right-hand side front frame rail.
[0056] The solution allows for the installation of a computer that is not entirely waterproof. Indeed, the vertical positioning of the support results in a vertical positioning of the computer so as to arrange the two connections or interfaces 41, 42 as high as possible. Thus, in the event of the vehicle 1 passing through a deep puddle, and / or heavy rain, and / or flooding, or even fording a stream, the computer is above the rear crossmember 4, i.e., at a considerable height. This height prevents the computer from being submerged under such conditions. In other words, arrangement 2 prevents either computer from ending up in the water. At the front, preferably above the frame rail, the computer is higher and therefore less exposed to the risk of immersion.
[0057] Although not illustrated, the shape of the support could be different, for example, with an angle between the lower wall 21 and the fifth wall 25 other than 90 degrees. For example, this angle could be between 120 and 90 degrees, or even between 150 and 120 degrees. Alternatively, the angle between the lower wall 21 and the fifth wall 25 could be less than 90 degrees. As a reminder, the computer is preferably fixed against the fifth wall, on the side of the opening in the support, i.e., against the receiving face 11.
[0058] It should be noted that the various means of fixing the support for receiving a control unit, namely holes 12, preferably opening into insert nuts 17, a hole 115, for example of a specific shape (neither circular, nor square, nor oblong, nor oval), at least one threaded rod 13 extending from the receiving face 11, allow the positioning and / or fixing of different control unit models. Thus, in the case of a vehicle equipped with a control unit model adapted to a type of sensor, for example, a vehicle meeting the Euro VI European environmental standard, and a vehicle equipped with another control unit model adapted to a different type of sensor, for example, a vehicle meeting the Euro VII European environmental standard, the same support can be used.This results in savings in terms of manufacturing (economies of scale), logistics (only one reference since there is only one type of support), ease of storage of these supports and finally avoids the risk of error in mounting the supports on the chassis. due to the single reference number. Furthermore, assembly time is reduced thanks to this single reference number.
[0059] As mentioned, two identical, standard brackets are mounted on each vehicle, one at the front and the other at the rear. Alternatively, a single bracket, or three brackets, or even more brackets, are arranged on the same vehicle. Given the bracket's compatibility with different models of computer or electronic control units, the bracket can be used on many different vehicle models.
[0060] Thus, despite the rear underbody placement of the second computer, it is not submerged in the event of a ford, for example. The computer can therefore be located near the exhaust line 7 without risk of immersion if the vehicle passes through water, mud, or other substances.
[0061] As a note, the solution therefore achieves the objective of housing computers in such a way as to avoid their immersion, despite their placement under the body, and has the advantage of offering great compatibility for the fixing of different computer models and can therefore be adapted to other land vehicles such as buses, coaches, or heavy goods vehicles for example.
