[0032] The detailed description set forth below provides information and examples of the disclosed technology with sufficient detail to enable those skilled in the art to practice the disclosure.
[0033] A vehicle 10 is shown in Figure 1. In the example, the vehicle 10 comprises a cab 12 and a semi-trailer 14.
[0034] The cab 12 comprises a driver seat 16, a passenger seat 18, a windshield 20 and doors 22. The cab is further delimitated by a floor 24 and a rear wall 26.
[0035] As an alternative, not shown, the cab 12 only comprises a driver seat 16.
[0036] A longitudinal axis X of the cab 12 is defined as an axis extending from the rear wall 26 to the windshield 20. A transversal axis Y of the cab 12 is defined as an axis extending perpendicular to the longitudinal axis X, extending between the driver seat 16 and the passenger seat 18.
[0037] In the example, the vehicle 10 can be driven, or controlled, either manually, by a driver seated in the driver seat 16, or automatically. Hence, the vehicle is considered as an automated vehicle. When the vehicle is driven automatically, the driver seat 16 can be used by a passenger of the vehicle. As an alternative, not shown, the vehicle 10 can only be driven automatically and the passenger seat 18 and the driver seat 16 are optional.
[0038] To automatically control the vehicle 10, the vehicle 10 comprises a modular platform 30, which is described in more detail with reference to Figures 2 to 5.
[0039] The modular platform 30 comprises electronic components 32, which are only shown in Figure 5 for the clarity of the figures. The electronic components 32 include preferably at least one communication module to receive and send data and at least one electronic control unit to analyze data. The electronic components 32 are configured to collect data about the vehicle 10 and its environment and to analyze this data to generate control signals, to operate the vehicle. In other words, the electronic components 32 are used to automatically drive the vehicle 10.
[0040] For example, the data collected by the electronic components 32 are data provided by sensors of the vehicle 10, such as cameras, radars, lidars, scanners and / or speed sensors, and / or data provided by external sources, such as an external server providing navigation data. For example, the control signals generated by the electronic components 32 are acceleration control signals, steering control signals and / or headlight control signals for operating, or driving, the vehicle 10. Hence, the electronic components 32 monitor and control various parameters of the vehicle 10, and in particular parameters related the driving of the vehicle. The electronic components 32 are known per se and are therefore not described in more details.
[0041] To protect the electronic components 32, the modular platform comprises an enclosure 34, within which the electronic components 32 are located, that is, installed. In otherwords, the enclosure 34 defines an internal volume within which the electronic components 32 are located.
[0042] In the example, the enclosure 34 comprises a beam structure 36, which includes several beams fixed together, for example by welding or with fasteners. In the example, the beam structure 36 is rectangular, improving its stiffness. The beam structure 36 allows the enclosure 34 to be rigid and therefore to protect the electronic components 32.
[0043] The enclosure 34 further comprises panels 38, fixed to the beam structure 36 to close at least some of the sides of the beam structure 36. Only two panels 38 are represented, in Figure 5, for the clarity of the drawings. Furthermore, one of the two panels 38 is only partially represented. The beam structure 36 and the panels 38 delimit the internal volume of the enclosure.
[0044] Thanks to the panels 38, the enclosure 34 is at least partially closed, which allows environmental conditions inside the enclosure 34, i.e. in its internal volume, to be different from the environmental conditions outside the enclosure, i.e. inside the cab. Said environmental conditions are, for example, temperature and humidity level.
[0045] As a variant, not shown, the enclosure 34 only comprise panels 38, which are self- supporting panels fixed together. In other words, in such a variant, the enclosure does not comprise a beam structure.
[0046] Preferably, the modular platform 30 comprises a temperature regulation system 39, which is only represented in Figure 5, for the clarity of the drawings.
[0047] The temperature regulation system 39 regulates the temperature within the enclosure 34, to maintain a temperature corresponding to the operating temperature of the electronic components 32, thus preventing overheating of the electronic components.
[0048] In the example, the temperature regulation system 39 comprises two fans, which replace the air in the enclosure 34 with cooler air from the cab 12. Preferably, the enclosure 34 comprises openings in the panels 38 allowing air from the cab 12 to enter the enclosure.
[0049] Preferably, the temperature regulation system 39 is connected to an HVAC system of the vehicle 10, more precisely to an HVAC system of the cab 12. Said HVAC is known per se and allows for climate control within the cab 12, for the comfort of the occupants of the cab. In particular, the HVAC system of the cab 12 includes air conditioning, which is connected to the temperature regulation system 39 so as to provide ventilation to the enclosure 34, allowing regulating the temperature within the enclosure. For example, the temperature regulation system 39 comprises a bellow, not shown. The bellow has two ends, a first end of the bellowbeing attached to the enclosure 34, a second end of the bellow being attached to the HVAC system of the cab 12, and more precisely to an air distribution system of the HVAC system of the cab. Therefore, the bellow convey ventilation generated by the HVAC system to the enclosure 34. Furthermore, the flexibility of the bellow compensates for the relative movement of the envelope 34 with respect to the cabin 12 caused by cabin vibrations, as detailed below.
[0050] As a variant, not shown, the temperature regulation system 39 comprises a liquid cooling circuit, comprising an internal heat exchanger, located in the enclosure 34 and absorbing the heat produced by the electronic components 32, an external heat exchanger, located outside the enclosure 34 and liquid pipes for transporting the heat absorbed by the internal heat exchanger to the external heat exchanger. The external heat exchanger is, for example, equipped of fans to dissipate the heat in the cab 12 or outside of the cab, or is connected to the HVAC system of the cab. The use of a liquid cooling circuit is particularly advantageous to minimize the openings in the enclosure 34, as no opening is needed to allow air to enter the enclosure from the cab 12. Hence, the environmental conditions within the enclosure 34 are more independent from those of cab 12 and are therefore easier to control.
[0051] As a variant, not shown, the temperature regulation system 39 comprises a dehumidifier, to control the humidity level within the enclosure 34.
[0052] Advantageously, the panels 38 are made in an electrically conductive material, such as steel panels, or comprise an electrically conductive material, such as a mesh or wires. Therefore, the panels 38 are electrically conductive. In other words, the panels 38 comprise an electromagnetic insulator, shielding the enclosure 34. Hence, the enclosure acts like a Faraday cage surrounding the electronic components 32, protecting the electronic components from electromagnetic interference. This makes the electronic components 32, as well as connection cables within the enclosure, to be less likely to be affected by electromagnetic interference, increasing signals reliability.
[0053] The enclosure 34 further comprises mounting brackets 40, to which the electronic components 32 are fixed, for example with fasteners. Hence, the electronic components 32 are securely fixed to the enclosure 34.
[0054] The electronic components 32 are generally fragile components, which can be damaged by excessive vibrations. To protect the electronic components 32 from the vibrations produced by the vehicle 10 during its operation, the modular platform 30 comprises a suspension system 50, which mounts the enclosure 34 to the vehicle 10 and isolate theenclosure from the vibrations of the vehicle. More precisely, isolating the enclosure from the vibrations of the vehicle means decoupling the vehicle vibrations from those of the enclosure.
[0055] In the example, the enclosure 34 is mounted inside the cab 12 by the suspension system 50.
[0056] Thanks to the suspension system 50, the enclosure 34 is suspended inside the cab and is therefore isolated from the vibrations of the cab 12. Hence, the electronic components 32 are not affected by the vibrations of the vehicle 10, in the example of the cab 12.
[0057] In the example, the suspension system 50 comprises eight vibrations dampeners 52, which, in addition to suspending the enclosure 34 and decouple the vibrations of the vehicle from those of the enclosure, dampen the vibrations transmitted from the cab 12 to the enclosure by the suspension system 50.
[0058] Moreover, in the example, four of the eight vibrations dampeners 52 are located at the bottom of the enclosure 34 and four of the eight vibrations dampeners 52 are located at the top of the enclosure 34, preventing oscillating movements of the enclosure.
[0059] Preferably, the vibrations dampeners 52 are wire rope isolators. Each wire rope isolator comprises a first retaining bar 54, fixed to the enclosure 34, a second retaining bar 56, used to fix the wire rope isolator 52 to the cab 12, and a metal cable 58, or wire rope, fixed to the first and second retaining bars. The wire rope isolators are known per se and are, for example, as described in US-A-4397069 or in US-A-4783038.
[0060] As a variant, not shown, the vibrations dampeners 52 are not wire rope isolators, but air or hydraulic dampeners. Such air or hydraulic dampeners are preferably controlled by electronic means to act as active suspensions.
[0061] As a variant, not shown, the suspension system 50 further comprises vibration sensors, fixed to the enclosure 34 to detect vibrations of the enclosure and active suspensions, controlled to attenuate vibrations of the enclosure 34 on the basis of the data supplied by the vibrations sensors. The active suspensions are, for example, a hydraulic or pneumatic cylinder controlled by a pump. The active suspensions can be used in addition, or in replacement, of the vibration dampeners 52.
[0062] Preferably, the modular platform 30 also comprises an outer structure 60. The outer structure is fixed to the vehicle, in the example to the inside of the cab 12, preferably to the floor 24 and to the rear wall 26 of the cab.
[0063] In the example, the outer structure 60 comprises a beam structure 62, giving rigidity to the outer structure 60, and fixing brackets 64 for attachment to the cab 12, preferably fasteners such as screws or bolts.
[0064] The dimensions of the outer structure 60 are designed to be larger than those of the enclosure 34, so that the enclosure is received within the outer structure 60. Furthermore, the second retaining bar 56 of each wire rope isolator 52 is fixed to the outer structure 60, so that the enclosure 34 is suspended to the outer structure 60.
[0065] Hence, the enclosure 34 is mounted to the cab 12 by means of the suspension system 50 and via the outer structure 60.
[0066] The construction of the modular platform 30, using the enclosure 34 within which the electronic components 32 are mounted, the outer structure 60 fixed to the cab and the suspension system 50 to suspend the enclosure to the outer structure, is particularly advantageous, as it facilitate the assembly of the modular platform 30, which can be made outside of the vehicle, as well as the fixation of the modular platform 30 inside of the cab 12, which is easily made by fixing the fixing brackets 64 to the cab.
[0067] Furthermore, fixing the suspension system 50 to the outer structure 60, and not directly to the cab 12, allows better control of the assembly of the wire rope isolators 52, and therefore of their performance. For example, this ensures that the wire rope isolators 52 are not deformed when the modular platform 30 is at rest. The modular platform 30 is considered “at rest” when no force applies on the enclosure 34 and on the outer structure 60 and when the enclosure 34 and the outer structure 60 are not vibrating.
[0068] Preferably, the outer structure 60 is fixed to the floor 24 and to the rear wall 26 of the cab 12. In other words, the outer structure 60 is fixed to interior surfaces of the cab 12.
[0069] Therefore, the outer structure 60 is subject to a vibration profile identical to that of the cab 12, to which it is attached, while the enclosure 34 and the electronic components 32 are subjected to a vibration profile different from that of the cab, thanks to the suspension system 50. In practice, the vibration profile of the enclosure 34 is attenuated compared with the vibration profile of the cab 12, thus protecting the electronic components 32. Since the vibration profile of the enclosure 34 is distinct from the vibration profile of the cab 12, the enclosure is decoupled from vibrations of the vehicle, that is, isolated from vibrations of the vehicle.
[0070] In a variant, not shown, the modular platform 30 does not comprise an outer structure and the second retaining bars 56 of the wire rope isolators 52 are fixed directly to the interior surfaces of the cab 12, for example to the floor 24 and to the rear wall 26 of the cab.
[0071] Preferably, the modular platform 30 is located, inside the cab 12, between the driver seat 16 and the passenger seat 18, along the transversal axis Y of the cab. In the example, the modular platform 30 is located is the center of the cab 12, along the transversal axis Y.
[0072] Preferably, the modular platform 30 is located, inside the cab 12, at least partially behind the driver seat 16 and the passenger seat 18, along the longitudinal axis of the cab, that is, between the driver and passenger seats and the rear wall 26. In the example, the modular platform 30 is located behind the driver and passenger seats, that is between the driver and passenger seats and the rear wall 26.
[0073] This localization of the modular platform 30 within the cab 12 is particularly advantageous for minimizing the vibrations experienced by the modular platform. Indeed, thanks to the conception of the cab 12 and its own dampening system, the cab is subjected to less vibration in its center than an its sides, along the transversal axis Y, and is subjected to less vibration near the rear wall 26 than near the windshield 20, along the longitudinal axis X.
[0074] The location of the modular platform 30 within the cab 12 and the use of the suspension system 50 allows isolating the enclosure 34 from the vibrations of the vehicle 10, thus protecting the electronic components 32 from these vibrations.
[0075] The modular platform further comprises power cables 70 and data cables 72, which are shown, in simplified, form only in Figure 3. The power cables 70 connect the electronic components 32 to a power source of the vehicle 10, to power the electronic components. The data cables 72 allows exchanging data between the electronic components 32 and the vehicle 10. Preferably, the data cables 72 are Ethernet cables. For example, the data cables 72 allows for data provided by sensors of the vehicle 10 to be transmitted to the electronic components 32 and allows for control signals emitted by the electronic components to be transmitted to the vehicle 10. In other words, the data cables 72 connect the electronic components 32 to sensors and / or actuators of the vehicle 12. The power cables 70 and the data cables 72 therefore extend into the enclosure 34. To this end, an opening is made in a panel 38 or one side of the beam structure 36 is left open, without a panel.
[0076] Advantageously, the modular platform 30 comprises a first routing interface 74 and a second routing interface 76, which can be seen more clearly in Figure 3. The first routing interface 74 is fixed to the enclosure 34, in the example to the beam structure 36 of theenclosure. The second routing interface 76 is fixed to the outer structure 60, in the example to the beam structure 62. In a variant in which the modular platform 30 does not comprise an outer structure, the second routing interface 76 is directly fixed to the cab 12, for example to the rear wall 26.
[0077] To control the position of power cables 70 and of the data cables 72 despite the difference between the vibration profile of the cab 12 and the enclosure 34, the power cables 70 are fixed to the first routing interface 74 and to the second routing interface 76 and the data cables 72 are fixed to the first routing interface 74 and to the second routing interface 76.
[0078] Moreover, when the modular platform 30 is at rest, the length of the power cables 70 and of the power cable 72, measured between the first routing interface 74 and the second routing interface 76, is greater than the distance between the first routing interface 74 and the second routing interface 76. This provides flexibility for the cables 70 and 72, which are therefore not under tension even when the enclosure 34 and the outer structure 60 move away from each other under the effect of the vibrations of the cab 12. This prevents the power cables 70 and the data cables 72 from breaking.
[0079] In other words, the distance between the first routing interface 74 and the second routing interface 76 allows for free movement of the cables 70 and 72 without breaking them.
[0080] Advantageously, when the temperature regulation system 39 comprises a liquid cooling circuit, the liquid pipes of the liquid cooling circuit are also fixed to the first routing interface 74 and to the second routing interface 76.
[0081] As a variant, not shown, the modular platform 30 comprises more than one first routing interface and / or more than one second routing interface. For example, the modular platform 30 comprises first and second routing interfaces dedicated to the power cables 70 and comprises first and second routing interfaces dedicated to the data cables 72.
[0082] Preferably, the cab 12 can be tilted to allow access to an engine of the vehicle 10. To avoid an excessive stress on suspension system 50, i.e. on the wire rope isolators 52, when the cabin tilt, the modular platform 30 advantageously comprises a retaining system 80 to prevent displacement of the enclosure 34 relative to the cab 12, that is relative to the outer structure 60, greater than a predefined value when the cab tilts. For the clarity of the figures, the retaining system 80 is represented only in Figure 3. In the example, the retaining system 80 comprises a hook 82, fixed to the enclosure 34, in the example to the beam structure 36 of the enclosure 34, and a bracket 84, fixed to the outer structure, in the example to the beam structure 62 of the outer structure 60. The bracket 84 has a “U” shape and the hook 82 extends from thebeam structure 36 to the space formed between the bracket 84 and the beam of the beam structure 62 to which the bracket 84 is fixed, so as not to touch the bracket 84 nor said beam of the beam structure 62 when the modular platform 30 is at rest. The hook 82 and the bracket 84 cooperate together to limit the movement of the enclosure 34 relative to the outer structure 60 when the cab 12 tilts. The retaining system 80 is designed so as not to prevent movement of the enclosure 34 relative to the outer structure 60 smaller than the predefined value, so as not to prevent the suspension system 50 to absorb the vibrations transmitted from the cab 12 to the enclosure 34. Preferably, the predefined value is chosen to be less than the maximum amplitude of movement between the enclosure 34 and the outer structure 60 when the modular platform 30 is subjected to vibration. During a tilt of the cab 12, when the amplitude of movement between the enclosure 34 and the outer structure 60 reaches the predefined value, the hook 82 comes in abutment against the bracket 84 or against the beam structure 62 of the outer structure 60, thus preventing further movement of the enclosure 34 relative to the outer structure 60.
[0083] Thanks to the enclosure 34, the suspension system 50 and the temperature regulation system 39, the electronic components 32 are protected from the vibrations of the cab 12, from electromagnetic interference and from overheating. As a result, the electronic components 32 operate in an environment more suited to their sensitivity and present less risk of failure. The operation of the vehicle 10, when automatically driven by the electronic components 32, is therefore more reliable.
[0084] The assembly of the modular platform 30 inside of the cab 12 of the vehicle 10 is performed by, in this order: assembling the modular platform outside of the cab 12, by mounting the enclosure 34 to the outer structure 60 by the suspension system 50, i.e. with the wire rope isolators 52, by installing the electronic components 32 inside the enclosure 34, i.e. to the mounting brackets 40, by fixing the power cables 70 and the data cables 72 to the first routing interface 74 and to the second routing interface 76 and by engaging the first hook with the second hook of the retaining system 80; moving the assembled modular platform 30 inside the cab 12, either through an opening intended to accommodate the windshield 20 before the installation of the windshield, through an opening intended to accommodate one of the doors 22 before the installation of said door or through one of the doors 22, when said door is open or when the window of said door is open; andmounting the enclosure 34 to the cab 12 by the suspension system 50, in the example by fixing the outer structure 60 to the cab, i.e. by fixing the fixing brackets 64 of the outer structure 60 to the floor 24 and to the rear wall 26 of the cab.
[0085] Furthermore, if replacing the modular platform 30 after its installation is required, for example for maintenance purposes, the modular platform can be dismounted from the cab and taken outside of the cab 12 as a whole, through the doors or through the opened windows of the doors. Hence, maintenance of the modular platform 30 is particularly easy to perform. Furthermore, a used modular platform 30 can easily be exchanged with a new modular platform 30 in case of failure or if an upgrade is needed, giving the modular platform 30 its modular nature.
[0086] As an alternative, the assembled modular platform 30 can be moved inside the cab 12 through an opening of the rear wall 26 of the cab 12 and then mounted to the cab by the suspension system 50. Preferably, in such an alternative, said opening of the rear wall 26 is closed with a rear panel and the rear panel is fixed to the outer structure 60 of the modular platform during the assembly of the modular platform. Therefore, when the modular platform 30 is moved inside the cab 12, the rear panel closes the opening of the rear wall. Such rear panel is for example fixed to some of the fixing brackets 64. In addition, such rear panel comprises fastening elements allowing the rear panel to be fixed to the rear wall 26 of the cab, or directly to a structure of the cab, to close the opening of the rear wall.
[0087] With reference to Figure 6, an automated vehicle 100 according to another example is now described.
[0088] The automated vehicle 100 is a complete autonomous haulage system, with a chassis 102, a tipper 104 mounted onto the chassis and four wheels 106. Preferably, the tipper 104 is articulated relative to the chassis 102, by means of a jack 108.
[0089] The automated vehicle 100 comprises a modular platform 110. The modular platform 100 is similar to the modular platform 30 of the vehicle 10 of the previous example, and differs from the modular platform 30 only in that it comprises a fully closed outer structure 112, which is fixed to the chassis 102 of the vehicle 100.
[0090] The modular platform 100 also comprises an enclosure, electronic components and a suspension system similar of those of the modular platform 30 of the vehicle 10 of the previous example, the suspension system mounting the enclosure to the outer structure 112. Furthermore, the automated vehicle 100 is autonomously controlled by the electronic components.
[0091] Preferably, the outer structure 112 comprises a hatch 114 allowing access to the interior of the modular platform and thus to the electronic components.
[0092] The use of the modular platform 100 to control the automated vehicle 100 is particularly advantageous, as it allows protecting the electronic components from the vibrations of the chassis 102, thus improving their reliability.
[0093] Furthermore, the completely closed outer structure 112 protects the electronic components of the modular platform 110 from dust and debris, avoiding degradation of the electronic components, and also facilitates the control of the temperature within the enclosure.
[0094] In addition, the outer structure 112 can also acts like a Faraday cage protecting the electronic components from electromagnetic interference, so that closing the enclosure 34 with panels is not necessary. However, if the enclosure is also closed with panels, as in the modular platform 30 of the previous example, the protection of the electronic components is improved as the outer structure 112 and the closed enclosure act as two successive barriers.
[0095] With reference to Figure 7, an enclosure 200 is now described.
[0096] The enclosure 200 is intended to be use in a modular platform, such as the modular platform 30, in replacement of the enclosure 34 previously described, or the modular platform 110.
[0097] Instead of a beam structure 36 and panels 38, the enclosure 200 comprises a composite shell 202, comprising an outer wall 204, an inner wall 206 and a thermal insulator 208 between the outer wall and the inner wall. The outer wall 204 and the inner wall 206 are electrically conductive. For example, the outer wall 204 and the inner wall 206 are made of an electrically conductive material such as sheets of metal such as steel, or comprise an electrically conductive material, such as a mesh or wires.
[0098] The composite shell 202 defines an internal volume within which the electronic components 32 are located.
[0099] By being electrically conductive, the outer wall 204 and the inner wall 206 form an electromagnetic insulator, shielding the enclosure 200. Hence, the enclosure 200 acts like a Faraday cage surrounding the electronic components 32, protecting the electronic components from electromagnetic interference.
[0100] Furthermore, the thermal insulator 208 ensures that the temperature within the internal volume of the composite shell 202 is easier to control with the temperature regulation system 39 of the modular platform to which the enclosure 200 belongs. The thermal insulator 208 is made of a material having a low thermal conductivity while having a good structuralintegrity, for instance of expanded polypropylene. In addition to providing thermal insulation, the thermal insulator 208 contributes, with the outer wall 204 and the inner wall 206, to the structural rigidity of the composite shell 202.
[0101] Preferably, to reinforce the electromagnetic protection offered by the enclosure 200, the composite shell 202 further comprises an electrically conductive intermediate wall 210, located between the outer wall 204 and the inner wall 206. In other words, the thermal insulator 208 is located on both sides of the intermediate wall 210. For example, the intermediate wall 210 is made of an electrically conductive material such as sheets of metal such as steel, or comprises an electrically conductive material, such as a mesh or wires.
[0102] Preferably, the composite shell 202 is built in several parts assembled together. In the example, the composite shell 202 comprises a top part, a bottom part and a side wall. To assemble the different parts of the composite shell 202 together while offering continuity in the electrical conductivity of the enclosure 200 the enclosure comprises connectors 212.
[0103] Each connector 212 is used to mechanically join two parts of the composite shell 202, for example the top part to the side wall, and to provide electrical continuity of the outer wall 204, the inner wall 206 and the intermediate wall 210 between said two parts of the composite shell.
[0104] In the example, each connector 212 comprises three electrical connectors 214, respectively providing electrical continuity of the outer wall 204, the inner wall 206 and the intermediate wall 210 between two parts of the composite shell 202.
[0105] To allow the power cables 70 and the data cables 72 to go through the enclosure 200, the enclosure comprises at least one hole, not shows. Advantageously, the hole is small enough not to diminish the electromagnetic protection offered by the enclosure.
[0106] Preferably, a first routing interface 74, not shown, is fixed to the enclosure 200, to control the position of power cables 70 and of the data cables 72 going out of the enclosure.
