Description

[0001] The invention relates to a method for assembling and a method for disassembling a sensor module of a motor vehicle. State of the art

[0002] Vehicle roofs are a familiar concept in practice. For example, a vehicle roof can be designed as a roof sensor module, which can be mounted as a separate unit onto the vehicle body of a motor vehicle, forming the basic vehicle structure.

[0003] Autonomous or semi-autonomous vehicles include, for example, a vehicle roof designed as a sensor roof module (RSM), which can be equipped with a variety of environmental sensors. Such environmental sensors can also be located on other parts of the vehicle. These sensors, such as lidar sensors, radar sensors, and / or cameras, detect the vehicle's surroundings and provide corresponding measurement signals to the vehicle's control electronics. This allows, for example, the vehicle to determine the current traffic situation and / or adapt its driving behavior accordingly.

[0004] Various mounting concepts are known for attaching an environmental sensor to a motor vehicle or its roof. These concepts differ primarily in how a sensor module is attached to the vehicle body. For example, the sensor module can be mounted "from above" onto a frame structure of the vehicle body. Alternatively, the sensor module can also be attached "from below" to such a frame structure. Furthermore, several concepts are known for separating a dry area and a wet area of ​​the sensor module.

[0005] Even though some assembly and maintenance concepts are already known, there is still potential for development.

[0006] Particularly when installing or maintaining the sensor module from below, a large clearance or cutout in a support element of the vehicle body is necessary to mount the sensor module components. Such a clearance or cutout leads to a structural weakening of the support element in question, necessitating a reinforcement concept to compensate for this weakening. Furthermore, the sensor module can only be installed and removed from below. During removal, additional components such as reinforcement plates, cables, covers, brackets, clips, and / or lights, etc., may need to be removed before the sensor module or its components can be removed from the inside. This is a complex and time-consuming process.

[0007] German patent application DE 10 2022 134 358 B3 discloses a roof module with an environmental sensor, which is equipped with an adjustment mechanism comprising a drive and a lever arrangement. The adjustment mechanism is mounted on a frame structure of the roof module.

[0008] It is therefore an object of the invention to provide an improved method for mounting a sensor module of a motor vehicle and / or an improved method for disassembling and / or maintaining a sensor module of a motor vehicle.

[0009] The problem is solved by a method for assembly with the features of claim 1. The problem is solved by a method for disassembly or maintenance with the features of claim 6.

[0010] Advantageous aspects of the invention are the subject of the dependent claims. The scope of the invention encompasses all combinations of at least two features disclosed in the description, the claims, and / or the figures. It is understood in particular that linguistic transformations and / or the meaningful substitution of respective terms within the framework of usual linguistic practice, especially the use of synonyms supported by generally accepted linguistic literature, are included in the present disclosure without being explicitly mentioned in their respective formulations.

[0011] In a preferred aspect, a method for mounting a sensor module of a motor vehicle is proposed, the sensor module comprising a sensor module carrier, an adjustment kinematics with a drive and a lever arrangement, and an environment sensor adjustable relative to the sensor module carrier by means of the adjustment kinematics, wherein the motor vehicle has a body carrier, wherein the method comprises the steps of: arranging the sensor module carrier on the body carrier; mounting the lever arrangement and the environment sensor on the sensor module carrier from outside the motor vehicle; and mounting the drive on the sensor module carrier or on the body carrier from inside the motor vehicle to connect the drive to the lever arrangement.

[0012] The assembly process can be used, for example, for mass production.

[0013] In a further preferred aspect, a method for disassembling and / or servicing a sensor module of a motor vehicle is proposed, the sensor module comprising a sensor module carrier, an adjustment kinematics with a drive and a lever arrangement, and an environment sensor adjustable relative to the sensor module carrier between a retracted position and an extended position by means of the adjustment kinematics, wherein the motor vehicle has a body carrier, wherein the method comprises the steps of: moving the environment sensor into the extended position; releasing the drive from the lever arrangement from inside the motor vehicle; and disassembling at least components of the lever arrangement and / or the environment sensor from the sensor module carrier from outside the motor vehicle in the extended position of the environment sensor.

[0014] The disassembly procedure can be used, for example, in service situations or for maintenance of the sensor module.

[0015] The methods claimed herein enable quick and easy assembly and disassembly. Furthermore, the methods require fewer components for the sensor module, thus making it more cost-effective. Moreover, the present design, in which at least parts of the lever assembly and the environmental sensor are accessible from outside the vehicle, allows easy access to the environmental sensor for servicing. The proposed service and maintenance concept, defined by the disassembly method, is also applicable regardless of whether the sensor module is mounted on the vehicle's body support, for example, on the roof, in a bottom-load configuration or with a top-load configuration.

[0016] The body support can be, for example, a front or rear crossmember. It can also be a side longitudinal member of the vehicle roof. The body support can also form another body component of the vehicle body.

[0017] The lever arrangement can be a multi-joint lever arrangement. The lever arrangement can have several levers by which the environmental sensor can be rotated about at least one axis of rotation and / or moved along at least one axis of travel. The lever arrangement can enable complex rotational and / or translational movement of the sensor. The lever arrangement is preferably driven by the drive, in particular by a motor.

[0018] The drive unit is, for example, housed in a casing. The casing may have mounting sections that allow the drive unit to be attached to the sensor module carrier or the body chassis, for example, by means of screws. The sensor module carrier can also be attached to the body chassis, for example, by means of screws. The sensor module carrier may also have suitable mounting sections for this purpose. The body chassis may also have suitable mounting sections.

[0019] In this case, the disassembly of the movable components of the sensor module, for example the lever arrangement (or the levers) and / or the environmental sensor (e.g. also a sensor housing and / or a cover) is carried out in an unfolded position or in the extended position of the environmental sensor.

[0020] For safety or theft protection reasons, it is neither desirable nor permitted to detach the moving components of the sensor module from the outside or from outside the vehicle. In this case, detachment of the moving components of the sensor module is only possible after the drive mechanism has been released from the inside. In its installed state, the drive mechanism thus secures the moving components from the inside, preventing them from being detached from outside the vehicle.

[0021] The sensor module may include further (functional) components such as a fan and / or cables and / or a cleaning device with cleaning nozzles and / or hoses, which are preferably all easily accessible from the inside or outside for disassembly in case of maintenance using the present method.

[0022] Preferably, the moving components of the sensor module are accessible from the outside. The non-moving components of the sensor module are preferably accessible from the inside.

[0023] In another aspect, it is proposed that the sensor module carrier be attached to the body support from outside the vehicle by placing the sensor module carrier on the body support or from inside the vehicle by attaching the sensor module carrier to the body support from inside the vehicle.

[0024] Setting up the system is also known as top-loading. Arranging it from the bottom up is also known as bottom-loading.

[0025] Furthermore, the top-load variant eliminates the need for a large cutout in the body support, resulting in increased stability of the support structure. In other words, the top-load variant preferably requires only a small service access opening for the drive unit (or its components, such as a bearing) in the body support. Therefore, separate reinforcement elements or a reinforced sensor module carrier are unnecessary. With the top-load variant, the sensor module carrier is preferably permanently attached to the body support, for example, by bolting. In the event of maintenance or servicing, it is not necessary to remove the sensor module carrier, including the sensor module, to access the other components of the sensor module.

[0026] In the bottom-load variant, a large cutout in the body support is still required, whereby the sensor module can be reinforced, for example, by an additional reinforcing plate or frame attached to the underside of the body support. In the bottom-load variant, the cutout or opening in the body support or in a surface component of the vehicle roof forming the roof skin is smaller than the outer edge of the sensor module carrier. Therefore, it is preferred that the moving components of the sensor module are arranged within this cutout or opening.

[0027] In another aspect, it is proposed that the sequence of arranging the sensor module carrier on the body carrier and mounting the lever assembly and the environment sensor on the sensor module carrier can be reversed from outside the vehicle.

[0028] The order can vary, especially between the top-load variant and the bottom-load variant, as is mentioned in detail in the character description.

[0029] In another aspect, it is proposed that mounting the lever assembly and the environment sensor on the sensor module carrier from outside the vehicle involves a movable attachment of components of the lever assembly to the sensor module carrier and an attachment of the environment sensor to components of the lever assembly.

[0030] The components can be attached directly or indirectly via additional components. For example, the components of the lever assembly are attached externally to the sensor module carrier, which is at least partially accessible from the outside.

[0031] In the bottom-load variant, the sensor module carrier is preferably trough-shaped. The sensor module carrier is preferably designed as a self-contained frame. The sensor module carrier is designed so that the movable or extendable components of the sensor module, such as the environmental sensor, a cover, and / or cooling elements and / or mechanical parts, etc., are accessible from above or from the outside.

[0032] In a further aspect, it is proposed that the drive comprises a coupling element and a bearing, preferably each with a seal, wherein the lever arrangement comprises a drive shaft, and wherein connecting the drive to the lever arrangement from inside the motor vehicle comprises connecting the coupling element to the drive shaft, in particular by placing the coupling element onto the drive shaft, and connecting the bearing to the drive shaft, in particular by placing the bearing onto the drive shaft.

[0033] Decoupling the drive is preferably achieved by disassembling the drive unit, including the coupling element with seal, on one side of the sensor module (viewed in the vehicle width direction), and on the other side (viewed in the vehicle width direction) by disassembling the bearing, including the seal. The coupling element and the bearing preferably protrude into a projected space of the opening in the body support. The drive shaft, including an interface of the lever assembly, is preferably located only within this projected space. Therefore, the movable components of the sensor module can be folded upwards without catching after the drive unit is detached.

[0034] In another aspect, it is proposed that detaching the drive from the lever arrangement from inside the vehicle involves dismantling the drive from the sensor module carrier or the body carrier from inside the vehicle.

[0035] This involves, for example, loosening screws that attach the drive to the sensor module carrier or the body carrier and dismantling the drive from inside the vehicle.

[0036] In a further aspect, it is proposed that the drive comprises a coupling element and a bearing, preferably each with a seal, wherein the lever arrangement comprises a drive shaft, and wherein releasing the drive from the lever arrangement from inside the motor vehicle comprises decoupling the coupling element from the drive shaft, in particular by releasing the coupling element from the drive shaft, and decoupling the bearing from the drive shaft, in particular by releasing the bearing from the drive shaft.

[0037] In another aspect, it is proposed that the body support have at least one opening, and that the mounting or dismounting of the drive is carried out from inside the motor vehicle via the at least one opening.

[0038] The present document also proposes a sensor module for a motor vehicle which, according to the method for mounting the sensor module in one of its embodiments, is mounted on the motor vehicle, or which, according to the method for dismantling or maintaining the sensor module in one of its embodiments, is at least partially dismantled from the motor vehicle.

[0039] Furthermore, a vehicle roof with such a sensor module is also proposed.

[0040] In a preferred aspect of the vehicle roof, it is designed as a roof sensor module. Such a roof sensor module forms an integrated unit that incorporates components used for the autonomous or semi-autonomous driving of the vehicle. The roof sensor module, which can integrate a variety of functional elements, thus represents a compact unit that is connected by the vehicle manufacturer to a vehicle body or body shell, which includes roof pillars such as side pillars and / or longitudinal pillars. The vehicle roof designed in this way as a roof sensor module is therefore a roof sensor module (RSM) that enables autonomous or semi-autonomous driving of the vehicle.

[0041] A motor vehicle equipped with such a roof and designed as an autonomous vehicle drives independently in autonomous driving mode, at least without significant driver intervention. In a semi-autonomous driving mode, the vehicle roof, according to the invention, forms, for example, part of a driver assistance system.

[0042] The vehicle roof may be equipped with a transparent fixed roof section and / or a roof opening system for a roof opening.

[0043] In particular, the vehicle roof forms at least part of the roof of a passenger car. However, it can also be the roof of a commercial vehicle, such as a delivery van, a bus, an autonomous minibus (like a so-called people mover), or a truck tractor.

[0044] The present claim also includes a motor vehicle comprising a sensor module and / or a vehicle roof of the type described above. The vehicle roof preferably forms a roof sensor module (RSM) that can be arranged as a pre-assembled unit on the vehicle body. In other words, a vehicle body shell can be provided with a prefabricated or pre-assembled roof sensor module designed as a roof sensor module.

[0045] It is understood that the aforementioned and subsequently explained embodiments and exemplary embodiments can be implemented not only individually, but also in any combination with one another, without departing from the scope of the present invention. It is also understood that the aforementioned and subsequently explained embodiments and exemplary embodiments relate in an equivalent or at least similar manner to all embodiments of the invention, without each being specifically named.

[0047] Fig. Figure 1 schematically shows a motor vehicle 1000, which has a vehicle body 1002. Furthermore, the motor vehicle 1000 has a roof sensor module 10, which is arranged as a pre-assembled unit on the vehicle body 1002 and forms at least a portion of the vehicle roof 100 of the motor vehicle 1000. The vehicle roof 100 extends along a longitudinal direction x of the vehicle and along a lateral direction y of the vehicle. The longitudinal direction x of the vehicle is orthogonal to the lateral direction y of the vehicle.

[0048] In alternative versions, the vehicle roof 100 can also refer to a vehicle roof that is not configured as a roof sensor module. Therefore, all versions also refer to such a vehicle roof 100.

[0049] The roof sensor module 10 comprises a surface component 12, which at least partially forms a roof skin 14 of the vehicle roof 100. The roof sensor module 10 comprises, according to Fig. 1. A fixed roof element 16, which forms at least a partially transparent area of ​​the vehicle roof 100. The roof sensor module 10 may, in other or supplementary versions, have a roof opening system comprising a cover element that can be moved to selectively open or close a roof opening.

[0050] The roof sensor module 10, or the vehicle roof 100, has a sensor module 18. The sensor module 18 can have a cover 20. Furthermore, the sensor module 18 has at least one environmental sensor 22 for detecting the vehicle's surroundings. The environmental sensor 22 is configured to detect the vehicle's surroundings via a viewing area 24. The viewing area 24 is located on the cover 20. The environmental sensor 22 can be a lidar sensor and / or a camera and / or a radar sensor and / or an ultrasonic sensor and / or a multi-camera sensor. Other sensors are also conceivable. Fig. 1 and Fig. Figure 3 shows the environmental sensor 22 in an extended position. According to Fig. Figure 2 shows the environmental sensor 22 in a retracted position. Furthermore, the sensor module 18 can have a cleaning device 26 for cleaning the viewing area 24. The cleaning device 26 can, for example, have several cleaning nozzles. The cleaning device 26 can, for example, be arranged on a sensor housing 28, to which the cover 20 is also attached, and in which the environmental sensor 22 is located.

[0051] In the following Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12, Fig. 13, Fig. 14, Fig. 15 to Fig. Figure 16 shows the sensor module 18 in various versions during assembly and / or disassembly.

[0052] The present procedure for mounting the sensor module 18 is shown schematically in the flowchart in Fig. 17. The present procedure for disassembling or maintaining the sensor module 18 is shown schematically in the flowchart in Fig. 18 shown.

[0053] The sensor module 18 further comprises a sensor module carrier 30, an adjustment kinematic mechanism 32 with a drive 34 and a lever arrangement 36. The environmental sensor 22 can be moved relative to the sensor module carrier 30 between a retracted position (see ) by means of the adjustment kinematic mechanism 32. Fig. 4) and an extended position (see Fig. 1 and Fig. 2) can be adjusted. The drive 34 can, for example, have an electric, pneumatic, hydraulic, and / or electromagnetic drive. In this example, the drive 34 is an electric motor. The lever arrangement 36 can have a drive shaft 38 and several levers 40. The drive 34 has a coupling element 42 and a bearing 44. The coupling element 42 also has a seal 46. The bearing 44 also has a seal 46.

[0054] The motor vehicle 1000 or the vehicle body 1002 has a body support 1004 on which the sensor module 18 can be arranged. There are primarily two types of arrangement.

[0055] On the one hand, the sensor module 18 can be arranged on the body support 1004 from below or inside the vehicle by arranging the sensor module carrier 30 (see Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11, Fig. 12 to Fig. 13) The weight of the sensor module 18 acts downwards and "pulls" on the body support 1004 in the direction of gravity, a configuration known as bottom-loading. In bottom-loading configurations, the sensor module 18 or the body support 1004 can be reinforced. Alternatively, the sensor module support 30 can be reinforced by a reinforcement frame 48. In bottom-loading configurations, the sensor module support 30 can preferably be designed, at least partially, in a trough-shaped form to accommodate components of the lever assembly 36, such as the drive shaft 38 and the multiple levers 40, as well as the ambient sensor 22, the cover 20, the cleaning device 26, and the sensor housing 28, and to make them accessible from the outside. The sensor module support 30 is therefore preferably open to the outside.The sensor module carrier 30 is preferably mounted from below on the body carrier 1004, in particular screwed to it, wherein the body carrier 1004 preferably has an opening which is dimensioned essentially complementary to an inner rim of the trough-shaped sensor module carrier 30.

[0056] On the other hand, the sensor module 18 can be positioned from outside the motor vehicle 1000 by placing the sensor module carrier 30 on the body carrier 1004 (see Fig. 14, Fig. 15 to Fig.16) The weight of the sensor module 18 acts from above on the body support 1004 and exerts pressure on it, in particular a top-load arrangement. In this top-load arrangement, the body support 1004 can preferably be designed, at least in some areas, in a trough-like shape. Furthermore, the body support 1004 can preferably have at least one opening 50 through which components of the sensor module 18 can be accessed from inside the vehicle. In this variant, the sensor module carrier 30 can, for example, be designed as a type of flat component that is placed on top of the body support 1004 and covers it externally.

[0057] The various components are each fastened by screws 52. However, other fastening methods are also possible.

[0058] To mount the sensor module 18, at least the following steps must be performed.

[0059] In step S1, the sensor module carrier 30 is positioned on the body carrier 1004. As already explained, the sensor module carrier 30 can be positioned on the body carrier 1004 from outside the vehicle 1000 (top-load) by placing the sensor module carrier 30 on the body carrier 1004, or from inside the vehicle 1000 (bottom-load) by attaching the sensor module carrier 30 to the body carrier 1004 from inside the vehicle.

[0060] In step S2, the lever assembly 36 and the environmental sensor 22 are mounted on the sensor module carrier 30 from outside the motor vehicle 1000. This involves the movable attachment of components of the lever assembly 36 to the sensor module carrier 30 and the attachment of the environmental sensor 22 or the sensor housing 28 to components of the lever assembly 36.

[0061] The sequence of arranging the sensor module carrier 30 on the body carrier 1004 and mounting the lever assembly 36 and the environmental sensor 22 on the sensor module carrier 30 from outside the vehicle 1000 can be reversed depending on the variant. In the top-load variant, for example, step S2 can be performed before step S1. In the bottom-load variant, for example, step S1 can be performed before step S2.

[0062] In step S3, the drive 34 is mounted on the sensor module carrier 30 or on the body carrier 1004 (depending on whether top-load or bottom-load) from inside the vehicle 1000 or from the vehicle interior side to connect the drive 34 to the lever assembly 36 or components of the lever assembly, such as the drive shaft 38. Connecting the drive 34 to the lever assembly 36 from inside the vehicle 1000 includes, for example, connecting the coupling element 42 to the drive shaft 38, in particular by attaching the coupling element 42 to the drive shaft 38, and connecting the bearing 44 to the drive shaft 38, in particular by attaching the bearing 44 to the drive shaft 38.

[0063] To dismantle sensor module 18, at least the following steps must be performed.

[0064] In step S10, the environment sensor 22 is moved into the extended position.

[0065] In step S11, the drive 34 is detached from the lever assembly 36 from inside the motor vehicle 1000 or from the vehicle interior. The drive 34 can be removed from the sensor module carrier 30 or the body carrier 1004. The detachment S11 can include decoupling the coupling element 42 from the drive shaft 38, in particular by detaching the coupling element 42 from the drive shaft 38, and decoupling the bearing 44 from the drive shaft 38, in particular by detaching the bearing 44 from the drive shaft 38.

[0066] In step S12, at least components of the lever arrangement 36 and / or the environment sensor 22 are disassembled from the sensor module carrier 30 from outside the motor vehicle 1000 in the extended position of the environment sensor 22.

[0067] The mounting or dismounting of the drive 34 from inside the motor vehicle 1000 can be carried out in the bottom-load variant via the at least one opening 50.
