Description

Technical Field

[0001] The present invention relates to a sensor module for mounting on a vehicle panel component as described in the preamble of claim 1. Background Technology

[0002] General-purpose sensor modules are technologically known and already in use in vehicle manufacturing. For example, such sensor modules are used to monitor the parking process, and ultrasonic sensors are commonly used as environmental sensors.

[0003] These sensor modules typically include a sensor housing and an environmental sensor, with at least a portion of the environmental sensor housed within the housing and configured to transmit and / or receive electromagnetic signals to detect the vehicle's environment, such as during parking. It is known that sensor modules can be rigidly mounted on top of panel members (the body portion of a motor vehicle). However, such placement is detrimental to the vehicle's visual appearance (known as styling) because the protrusion of the sensor module on the outer surface disrupts the vehicle's otherwise unobtrusive visual profile, which is generally perceived negatively by customers. Furthermore, the fixed position of the sensor module negatively impacts the vehicle's aerodynamics, as undesirable air turbulence may occur during driving. This turbulence leads to acoustic noise, which is typically perceived negatively by car passengers. Additionally, the disruptive aerodynamic profile can increase fuel consumption. Moreover, due to constantly changing environmental and weather conditions, the transparent area where the environmental sensor detects the vehicle's environment can accumulate dirt or become opaque, or even be damaged (e.g., by hail).

[0004] As part of the solution to these problems, sensor modules are known to be equipped with a motion system having a drive mechanism configured to move environmental sensors from a retracted position to an deployed position. Thus, the environmental sensor can retract when not needed, so that it no longer constitutes a disruptive acoustic and / or aerodynamic factor. Sensor modules moving in this manner can typically be moved individually, adjustable only between a fully closed position and a fully open position. However, when the moving sensor module or the environmental sensor is deployed, allowing the relevant environmental sensors to detect the vehicle's environment, they also constitute disruptive aerodynamic and visual factors.

[0005] Furthermore, the automotive manufacturing industry is increasingly focusing on autonomous and semi-autonomous driving vehicles. To enable vehicle controllers to automatically or semi-autonomously control vehicles, multiple environmental sensors (such as lidar sensors, radar sensors, (multi) cameras, and sensors including other (electrical) components) are employed. These sensors, for example, are integrated into the top module to detect the environment surrounding the vehicle and determine, for example, the current traffic conditions based on the detected environmental data. Top modules equipped with multiple environmental sensors are also known as Top Sensor Modules (RSMs). For this purpose, known environmental sensors send and / or receive appropriate electromagnetic signals, such as laser beams or radar beams, allowing for the generation of a data model of the vehicle environment through appropriate signal evaluation and its use in vehicle control. These environmental sensors used to monitor and detect the vehicle environment are typically mounted on the top of the vehicle, as the top is usually the highest point and the surrounding environment is easily visible from there. However, such sensor modules can also be arranged on other panel components of the vehicle to achieve comprehensive detection of the vehicle environment.

[0006] An exemplary top module is prefabricated as a separate functional module that can be supplied to the assembly line during the assembly of a motor vehicle. The top module at least partially forms a top skin for the vehicle roof on its outer surface, which prevents moisture and airflow from entering the vehicle interior. The top skin consists of one or more panel members, which can be made of stable materials such as painted metal or painted or molded plastic. The top module can be part of a fixed top or part of an openable top subassembly.

[0007] While it is generally known that sensor modules or environmental sensors are arranged in a retractable and deployable manner within the panel components of motor vehicles, existing solutions have several drawbacks that remain to be overcome. For example, known sensor modules can only move between a retracted position and a fully deployed position, which is disadvantageous. Furthermore, autonomous vehicles, especially those with multiple different environmental sensors, must each be individually integrated in a retractable and deployable manner into a relevant panel component, such as a top module. Therefore, each environmental sensor requires its own motion system, which must be installed and maintained. Moreover, the retraction and deployment of each environmental sensor must be individually controlled. This makes the technical system highly complex, which is reflected in higher production and maintenance costs. Summary of the Invention

[0008] Therefore, the object of this invention is to provide a sensor module and / or signal transmitter and / or signal receiver module that overcomes the shortcomings of the aforementioned existing technology, and is particularly less technically complex. Specifically, it reduces the number of required components, thereby also reducing associated production and maintenance costs. Furthermore, the object of this invention is to provide a panel component comprising at least one sensor module and / or signal transmitter and / or signal receiver module.

[0009] This objective is achieved through the top module according to the teachings of claim 1.

[0010] Advantageous embodiments of the present invention are the subject of the appended claims.

[0011] In their intended use, the sensor module and / or signal transmitter and / or signal receiver module according to the invention are configured to be disposed on a panel member of a motor vehicle (which constitutes, for example, part of the vehicle body), particularly in an opening in the panel member.

[0012] A sensor module according to a first aspect of the invention includes a sensor housing and at least one environmental sensor, at least a portion of which is disposed within the sensor housing and configured to transmit and / or receive electromagnetic signals to detect a vehicle environment. Furthermore, the sensor module according to the first aspect of the invention includes a motion system having a drive mechanism (e.g., provided by an electric motor and / or an electric stepper motor) configured to move the sensor housing (and the associated at least one environmental sensor) from a retracted position to at least one extended position. The sensor module according to the invention is characterized in that the motion system is configured to move the sensor housing (and the associated at least one environmental sensor) to a first extended position, which activates the at least one environmental sensor to detect the vehicle environment only in a portion of its field of view, and is configured to move the sensor housing to a second extended position, which activates the at least one environmental sensor to detect the vehicle environment in its entire field of view (i.e., throughout its entire field of view).

[0013] A sensor module according to a second aspect of the invention includes a sensor housing and first and second environmental sensors. Both the first and second environmental sensors are at least partially disposed within the sensor housing and are configured to transmit and / or receive electromagnetic signals to detect the vehicle environment. Furthermore, the sensor module according to the invention includes a motion system having a drive mechanism configured to move the sensor housing from a retracted position to at least one extended position. The sensor module according to the invention is characterized in that the motion system is configured to move the sensor housing (and at least one associated environmental sensor) to a first extended position, which activates the first environmental sensor to detect the vehicle environment, and in which the second environmental sensor is preferably not activated, and is further configured to move the sensor housing to a second extended position, which activates the second environmental sensor (also) to detect the vehicle environment. In the second extended position, which preferably corresponds to a fully extended position of the sensor housing, both the first and second environmental sensors are preferably activated.

[0014] In other words, the sensor module according to the invention is characterized by a motion system configured to move the sensor housing (and at least one associated environmental sensor) to a first deployed position, which activates the at least one environmental sensor to detect at least a portion of its field of view or its entire field of view, and / or to move the sensor housing to a second deployed position, which activates a second environmental sensor to detect at least a portion of its field of view or its entire field of view. Therefore, the sensor module may include one or more environmental sensors that, depending on their respective positions, are not activated or detect a portion of their field of view or detect their entire field of view. Furthermore, the kinematic system can, of course, be configured to move the sensor housing (and at least the associated environmental sensor) to any number of intermediate positions between the first and second deployed positions. Depending on the intermediate position, at least one environmental sensor can be activated to detect the vehicle environment partially or entirely within its field of view. The activation of at least one environmental sensor to detect an increasing amount of the vehicle environment can increase continuously or incrementally with the movement of the sensor housing.

[0015] The object of the present invention is further achieved by a signal transmitter and / or signal receiver module according to a third aspect, the module comprising a housing and at least one signal transmitter and / or signal receiver, at least a portion of which is disposed within the housing and configured to transmit and / or receive signals. Furthermore, the signal transmitter and / or signal receiver module according to the third aspect of the invention includes a motion system having a drive mechanism (provided by an electric motor and / or an electric stepper motor) configured to move the housing (and the associated at least one signal transmitter module and / or signal receiver) from a retracted position to at least one extended position. The signal transmitter and / or signal receiver module according to the invention is characterized in that the motion system is configured to move the housing to a first extended position, which activates at least one signal transmitter and / or signal receiver module to transmit and / or receive signals with only a portion of its transmission and / or reception capabilities, and is further configured to move the housing to a second extended position, which activates at least one signal transmitter and / or signal receiver to transmit and / or receive signals with its full transmission and / or reception capabilities.

[0016] The object of the invention is further achieved by a signal transmitter and / or signal receiver module according to a fourth aspect, the module comprising a housing and first and second signal transmitters and / or signal receivers. Both the first and second signal transmitters and / or signal receivers are at least partially disposed within the housing and are both configured to transmit and / or receive signals. Furthermore, the signal transmitter and / or signal receiver module according to the invention includes a motion system having a drive mechanism configured to move the housing from a retracted position to at least one extended position. The signal transmitter and / or signal receiver module according to the invention is characterized in that the motion system is configured to move the housing to a first extended position, which at least partially activates the first signal transmitter and / or signal receiver, in which the second signal transmitter and / or signal receiver is preferably not activated, and is also configured to move the housing to a second extended position, which at least partially (also) activates the second signal transmitter and / or signal receiver. In the second extended position, preferably corresponding to a fully extended position of the housing, both the first and second signal transmitters and / or signal receivers are preferably activated.

[0017] At least one signal transmitter and / or signal receiver is preferably a light source, an antenna, a communication module, or a speaker. Particularly preferred is that at least one signal transmitter and / or signal receiver is a light source for automated and / or automatic driving and / or semi-automatic driving modes.

[0018] Of course, the dependent claims, embodiments, and / or illustrative examples mentioned in relation to the sensor module are equivalent to the signal transmitter and / or signal receiver modules, even if not explicitly mentioned in their context. In particular, the interpretation of dependent claims 3 and 4 through 14 naturally also applies to the changes in terminology of the third and fourth aspects of the invention, respectively (environmental sensor will be replaced by signal transmitter and / or signal receiver; sensor module will be replaced by signal transmitter and / or signal receiver module).

[0019] The expression "at least one" means, according to the invention, that one or more components mentioned in a given context may be included. For example, a sensor module may include one or more environmental sensors, i.e., at least one environmental sensor. The sensor housing is preferably configured to fully accommodate at least one environmental sensor (i.e., first and second environmental sensors), and preferably to completely surround at least one environmental sensor. The sensor housing preferably forms a dry area inside, in which at least one environmental sensor is protected from moisture. In the "retracted position," the sensor housing is preferably arranged at the opening of the corresponding panel member such that it does not protrude from the opening. In the fully retracted position, at least one environmental sensor is inactive, that is, it does not detect the vehicle environment.

[0020] In at least one deployed position, at least one environmental sensor preferably protrudes from the relevant panel member to detect the vehicle environment. The first deployed position is preferably located between a retracted position and a fully deployed position. In the first deployed position, the sensor housing is preferably partially but not yet fully deployed, meaning that the sensor housing only partially protrudes from the panel member compared to the fully deployed position (preferably corresponding to the second deployed position). Once at least one environmental sensor is in the deployed position (e.g., the first deployed position), at least a partially visible area (through which at least one environmental sensor detects the vehicle environment) preferably protrudes from the panel member.

[0021] According to the invention, when in the first deployed position, the environmental sensor can detect only a portion of the vehicle environment because only a portion of its field of view protrudes from the panel member. Therefore, at least one environmental sensor is only partially activated to detect the vehicle environment. The other portion of the sensor's field of view remains disposed below the surface of the panel member, within the vehicle body. In the first deployed position, the environmental sensor detects only a portion of the vehicle environment, while the other portion of its field of view is covered and cannot be used for detection. This configuration is advantageous, for example, if only a specific portion of the vehicle environment needs to be detected, such as during parking, to detect necessary information. In this case, the invention allows the environmental sensor to deploy only partially, so that it does not protrude too far from the relevant panel member. This is also advantageous, for example, when the vehicle is traveling on a highway, where only a portion of the vehicle environment needs to be detected due to the absence of other interfering variables (pedestrians or the like). In this case, the environmental sensor can move only to the first deployed position and protrude relatively little from the panel member. This is particularly advantageous because the sensor housing or environmental sensor exhibits only a smaller destructive aerodynamic factor compared to the fully deployed position. Improved aerodynamics reduce noise and save fuel.

[0022] According to the invention, it is advantageous that a specific environmental sensor can be activated based on its unfolded position (e.g., first and second unfolded positions), while different environmental sensors remain inactive in this unfolded position. For example, when the sensor housing is moved to the first unfolded position, the first environmental sensor can be activated. On the other hand, the second environmental sensor remains inactive in the first unfolded position, i.e., it does not detect the vehicle environment. If the sensor housing is now moved to the second unfolded position, i.e., further extending from the panel member, the second environmental sensor is activated to detect the vehicle environment. This is a significant advantage because it is possible to selectively activate sensors based on the unfolded position. Therefore, separate environmental sensors are not required as in the art; instead, multiple environmental sensors can be integrated into a single sensor module and housed within a single sensor housing. If one of the environmental sensors is needed, the sensor housing can be moved to a predetermined unfolded position where the relevant environmental sensor is activated. This reduces the number of components compared to the prior art. Furthermore, the complexity of installation and maintenance is reduced because only a few sensor modules must be incorporated into the panel member. Therefore, environmental sensors do not require individual drive units; instead, multiple environmental sensors are integrated into a single sensor module. This makes the solution according to the invention more cost-effective and relatively lighter (lighter weight). Furthermore, the solution according to the invention is very compact, thus easy to install and maintain. Additionally, the aerodynamics of the sensor housing can be individually optimized for each deployment position, resulting in airflow around the sensor housing protruding from the panel members in an aerodynamically ideal manner at all times.

[0023] The field of view of an environmental sensor extends in a cone shape around its optical axis. The cone opening angle depends on the type of sensor and can be enlarged by optical elements, such as lenses or lens systems (e.g., in the case of a fisheye lens).

[0024] In a preferred embodiment of the first aspect, the motion system is configured to move the sensor housing to any intermediate position between a retracted position and a fully extended position, depending on a predetermined field of view required under specific conditions. For example, the sensor housing may also extend from the panel member only enough for the environmental sensor to detect a predetermined area of ​​the vehicle environment under specific conditions. If it is necessary to detect the entire vehicle environment, the sensor housing may be fully extended, if possible, to detect the vehicle environment across the entire field of view of the environmental sensor.

[0025] In a preferred embodiment of the second aspect, the kinematic system includes a controller configured to detect and / or adjust the current position of the sensor housing, preferably via a position detection sensor, and activate a first and / or a second environmental sensor based on the current position. For example, if the controller detects that the sensor housing is in a first deployed position, the controller activates the first environmental sensor. The second environmental sensor remains inactive, i.e., it is not activated by the controller. If the controller detects, for example, that the sensor housing is in a second deployed position or has been moved to that position, the controller activates the second environmental sensor. In the second position, the first environmental sensor may either remain active or be deactivated again by the controller.

[0026] Particularly preferred is that the first environmental sensor is placed on the sensor housing such that, when in the first deployed position, its viewing area (through which it detects the vehicle environment) protrudes from the panel member (i.e., the outer surface of the panel member). On the other hand, the second environmental sensor is preferably disposed on the housing such that, when in the first deployed position, its viewing area (through which it detects the vehicle environment) does not yet protrude from the panel member (i.e., the outer surface of the panel member). The viewing area of ​​the second environmental sensor does not protrude from the panel member (i.e., the outer surface of the panel member) until the sensor housing is moved to the second deployed position. Therefore, it is preferable that both environmental sensors protrude from the panel member in the second deployed position.

[0027] It should be noted that, in principle, other environmental sensors (such as a third environmental sensor) can be placed inside the sensor housing. The third environmental sensor can be placed on the sensor housing such that, for example, it is activated to detect the vehicle environment when in a third deployed position, which can be located between the first and second deployed positions.

[0028] In the second deployment position, according to the invention, the fields of view of the first and second environmental sensors preferably overlap to allow for redundant detection of certain portions of the vehicle environment. This can be advantageous, for example, for conducting reliability tests on the detected vehicle environment, since a redundant dataset is collected in this manner.

[0029] In a preferred embodiment, the motion system includes a slider. Furthermore, the drive mechanism preferably includes a drive gear. The drive mechanism is connected to the slider in a force-transmitting manner (directly or indirectly (interlocking with other components)) via a flexible shaft or spindle nut driver. Alternatively or additionally, the motion system may include a linear drive and / or an electromagnetic actuator and / or a gyro drive and / or a compressed air drive. Gyro drives are particularly advantageous for the rapid retraction of the sensor housing, for example, for pedestrian protection. For example, a flexible shaft or spindle nut driver or other operative connector (e.g., a lever connection) may be positioned on the preferred drive gear. The flexible shaft or spindle nut driver or operative connector is preferably force-transmittingly connected to the drive gear on one side. On its other side (relative to its longitudinal direction), the flexible shaft or spindle nut driver or other operative connector is force-transmittingly connected to the slider. The drive mechanism is preferably capable of moving the slider along its drive axis.

[0030] When using a spindle nut driver, the drive mechanism moves the spindle nut back and forth relative to the spindle. This relative motion between the spindle nut and the spindle can be converted into the motion of a sliding pin. When using a spindle nut driver, the sliding pin is preferably fixedly connected to the spindle nut, i.e., they rotate together, and its other end engages with a slot in a sliding manner.

[0031] In a preferred embodiment, the drive unit is configured to move (translate) the slider back and forth along the drive axis on a generally (i.e., considering deviations related to tolerances and functionality) guided, preferably straight, curved, circumferential, and / or similarly shaped track via a flexible shaft or spindle nut driver. The translation of the slider along the drive axis is preferably converted into rotation of the sensor housing about a rotation axis by a sliding pin fixed to the sensor housing, which causes the sensor housing and at least one environmental sensor (i.e., first and second environmental sensors) to move together from a retracted position to at least one extended position. For this purpose, the sensor housing is preferably attached to a panel member or substructure (e.g., a top frame or other body frame) such that it can be rotated via a guide rod.

[0032] In a preferred embodiment, a slot is provided in the slider, and a sliding pin is supported in the slot in a translationally movable manner. The sliding pin is preferably positioned stationary on the sensor housing and / or the spindle nut of the spindle nut driver. The sliding pin or guide pin is preferably slidable within the slot. Movement of the sliding pin along or within the slot preferably actuates movement of the sensor housing or environmental sensor, thereby moving the environmental sensor from a retracted position to at least one deployed position (a first deployed position and / or a second deployed position). The slider is preferably guided on a linear track (e.g., a track-like structure). The slot is preferably a predetermined groove on the slider, the shape and length of which allow for the desired motion sequence. Particularly preferred is that the slot includes a ramp-shaped track portion (having a ramp shape). In principle, other slot shapes are also possible. One advantage of controlling the slot is that it allows for optimization of the environmental sensor's movement speed while requiring minimal installation space for the motion mechanism. The sliding pin is preferably secured (e.g., by a protruding protrusion (similar to a rivet) or by a cotter pin) to prevent it from falling out of the slot.

[0033] The drive unit is preferably electrically driven. By providing a flexible shaft, the (rotational) motion of the motor is converted into linear motion of the drive unit via a drive transmission gear, ensuring a high degree of design freedom, as the drive unit can be placed almost in the lateral mounting space next to the environmental sensor. Particularly preferred is that the drive unit is configured to move the slider back and forth along a generally linear track via the flexible shaft. A "generally linear track" means that the slider is preferably only able to move along one axis of motion (e.g., an axis parallel to the vehicle's width direction), while its motion relative to the other two axes of motion is restricted (except for the degree of freedom necessary for construction) (i.e., it has only one degree of motion freedom).

[0034] In a preferred embodiment, the slot includes a ramp-shaped track portion. A drive mechanism is configured to move a slider such that a sliding pin slides along the ramp-shaped portion, the sliding pin being movable between a first stop of the slot (secured in the retracted position) and a second stop of the slot (secured in the fully extended position (preferably corresponding to the second extended position)). Movement of the sliding pin along the ramp-shaped track portion initiates rotation of the sensor housing about its axis of rotation relative to the panel member. The end portion of the slot acts as a stop, securing the sensor housing in either the retracted or fully extended position.

[0035] In one embodiment, the sensor module preferably includes at least one cleaning nozzle, which is, for example, disposed in a lateral region adjacent to the viewing area of ​​the environmental sensor, to clean the viewing area with a cleaning fluid (e.g., gas or liquid (e.g., soapy water)) when necessary. For example, at least one cleaning nozzle may be disposed in the housing portion where the viewing area is located. The cleaning nozzle may be retractable, deployable, or fixed. If the cleaning nozzle is retractable and deployable, it may be advantageous to retract and deploy it by water pressure or mechanical actuation. In principle, the slot may also include another track portion, such as a ramp-shaped track portion, and movement of a sliding pin in this second ramp-shaped portion allows at least one cleaning nozzle to be retracted and deployed. Thus, movement of the cover, environmental sensor, and cleaning nozzle can be provided by a single sequence of motion (movement of the sliding pin in the slot), and the individual movements of the cover, environmental sensor, and cleaning nozzle can also be performed independently of each other (i.e., by partially executing the sequence of motion).

[0036] In a preferred embodiment, the sliding pin is fixedly attached to the environmental sensor or sensor housing. Preferably, at least one environmental sensor (i.e., first and second environmental sensors) is rotatably mounted on the panel member (or the frame structure of the panel member) in this configuration, for example, by suspension from the sensor housing. The sensor housing preferably rotates only about one axis of rotation, otherwise it is fixed relative to the end module. For example, this configuration allows relative movement of the slider along the (linear) axis of motion, which is converted into rotation of the sensor housing about the axis of rotation by the sliding of the sliding pin in the slot, since the sliding pin is stationary, i.e., fixed, relative to the sensor housing. Thus, the sliding pin slides along the ramped slot between the first (lower) stop and the second stop, thereby changing its relative distance to the axis of motion of the slider, which is fixed in the vertical direction relative to the panel member, until the guide pin strikes the second stop, reaching the fully extended position.

[0037] The sensor module according to the invention can essentially include any type of environmental sensor. Particularly preferred is that the sensor module according to the invention employs a lidar sensor and / or a radar sensor and / or a camera sensor and / or an ultrasonic sensor and / or a multi-camera sensor as the environmental sensor. The first and second environmental sensors can be substantially the same sensor type or different sensor types. For example, the lidar sensor operates in a wavelength range of 905 nm or approximately 1550 nm. The sensor module preferably includes a transparent region through which the environmental sensor detects the vehicle environment. The material of the transparent region is preferably permeable to the wavelength range used by the environmental sensor and is selected according to the wavelength range used by the environmental sensor. Other sensor types can also be used in principle, but are not mentioned here.

[0038] Particularly preferred is that the invention also relates to a panel member of a motor vehicle having at least one opening in which at least one sensor module according to the invention is movably arranged. According to this embodiment, the sensor housing may include a cover or cover portion, which is preferably configured to close at least one opening flush and preferably moisture-proof when the sensor housing is in a retracted position. The cover is preferably configured to the shape of the opening to take into account manufacturing and functional tolerances so that it can close the opening. The bottom region of the cover preferably has a shape adapted to the geometry of the panel member to create an optically smooth appearance. The cover preferably includes a waterproof strip circumferentially disposed on the outer edge region of the cover and provides a seal relative to the panel member. Alternatively or additionally, the waterproof strip may also be disposed on the panel member, for example, on the edge region of the opening. When in the closed position, the cover preferably contacts the waterproof strip flush, thus achieving a moisture-proof seal relative to the opening. The shape of the sensor housing is also preferably such that it also provides a moisture-proof seal relative to the opening of the panel member in each unfolded position of the sensor housing.

[0039] In another preferred embodiment, the panel component is an outer covering part of a fender, bumper, sunroof, window, door, sliding roof, roof, folding roof, hood, front hood, or trunk lid. Other panel components of a motor vehicle not mentioned herein may also be included in principle by the present invention. Of course, a motor vehicle may include more than one of the above-described panel components, which preferably each include a sensor module according to the present invention. For example, the sensor module according to the present invention (according to the first and second aspects) may preferably be disposed in the front and / or rear and / or side areas of the roof or top module. In addition, the sensor module according to the present invention (according to the first and second aspects) may preferably be integrated in other places of the motor vehicle, such as fenders, A-pillars and / or B-pillars and / or C-pillars of the vehicle body, rear cover, bumper, and / or any other front or rear module, and used for detecting the vehicle environment.

[0040] Particularly preferred is that the invention also relates to a top module for forming the roof of a motor vehicle, the top module including a panel member that at least partially forms a top skin of the vehicle roof. The top skin serves as an external sealing surface of the top module. The panel member forming the top skin includes at least one sensor module according to any exemplary embodiment of the invention.

[0041] Furthermore, the present invention also relates to a motor vehicle comprising at least one panel member according to the invention. Particularly preferred is a motor vehicle comprising a top frame structure and the aforementioned top module, the top module being mountable as a structural unit on the top frame structure.

[0042] The top module can form a structural unit integrating automated or semi-automatic driving functions assisted by a driver assistance system, and can be placed on the vehicle body shell as a structural unit by the automaker. Furthermore, the top module according to the invention can be a purely fixed roof or a vehicle roof including a top opening system. Additionally, the top module can be configured for passenger cars or multi-purpose vehicles. The top module is preferably provided as a top sensor module (RSM) incorporating environmental sensors for insertion into the top frame of the vehicle body as a supplied structural unit.

[0043] Of course, the embodiments and illustrative examples mentioned above and discussed below can be implemented individually and can be combined with each other in any way without departing from the scope of the invention. Furthermore, any and all embodiments and illustrative examples of the sensor module also relate to panel members, particularly top modules, including such sensor modules, and motor vehicles having such panel members, particularly such top modules.

[0053] Figure 1 A motor vehicle 1000 having a vehicle roof 100 is shown. The vehicle roof 100 is formed by a roof module 10 in this application. The roof module 10 can be placed as a structural unit on the roof frame structure 102 of the motor vehicle body, the placement of which is indicated by dashed lines. The roof module 10 includes a first panel member 12 for forming a top skin 14 of the vehicle roof 100. In the front middle top portion of the roof module 10 relative to the vehicle length direction x, a first sensor module 16 is arranged in an opening in the first panel member 12 in a retractable and deployable manner. The first sensor module 16 is arranged directly behind a front crossbeam 104, which defines the head of the vehicle roof. The front crossbeam, rear crossbeam 104, and two side beams 106 together constitute the roof frame structure 102.

[0054] The first sensor module 16 includes a first environmental sensor 17, such as a multi-camera first environmental sensor, and a second environmental sensor 18, such as a lidar sensor. Other types of sensors, such as (multi-directional) cameras and / or ultrasonic sensors, may also be used. Furthermore, the sensor module 16 includes a sensor housing 19, in which both the first environmental sensor 17 and the second environmental sensor 18 are at least partially housed. In this application, both environmental sensors 17 and 18 are completely housed within the housing. However, the sensor housing 19 may also be a partial housing or a portion of the housing. Both the first and second environmental sensors 17 and 18 are configured to transmit and / or receive electromagnetic signals to detect the vehicle environment of the motor measurement 1000 (e.g., for autonomous driving or parking).

[0055] In this application, the vehicle body includes components other than the top frame structure 102, all of which are covered by panel members that form the outer skin of the vehicle. For example, the vehicle body includes a fender 108, of which a rear wheel fender (not shown) is shown in this application. The fender 108 is covered by a suitably shaped second panel member 20 that defines the outer skin of the fender 108. A second sensor module 22 is disposed in an opening in the second panel member 20 in a retractable and deployable manner. The first sensor module 16 and the second sensor module 22 may be the same or technically different sensor modules (e.g., including other environmental sensors 18). Interpretations relating to the first sensor module 16 are equivalent to those relating to the second sensor module 22. Interpretations relating to the second sensor module 22 are, in turn, applicable to the first sensor module 16. In this application, the first sensor module 16 differs from the second sensor module 22 in that the first sensor module 16 includes first and second environmental sensors 17 and 18, while the second sensor module 22 includes only one environmental sensor. The environmental sensor of the second sensor module 22 is the same as that of the second environmental sensor 18, and therefore the same reference numerals are provided. For simplicity, the first and second sensor modules 16 and 22 will also be simply referred to as sensor modules 16 and 22.

[0056] Figure 2 A detailed view of a portion of a mudguard 108 is shown, which includes an opening in which sensor modules 16, 22 are positioned in a retractable and deployable manner. Sensor modules 16, 22 also include a motion system 24 having a drive 26 configured to move sensor housing 19 from a retracted position (see...). Figure 3 (a), 4(a), 6(a), 7(a) and 8(a)) are moved to at least one unfolded position. Figure 8 The drive unit 26 is schematically shown, which can be an electric motor or an electric stepper motor. Other drive units or drive types (mechanical and / or pneumatic drives) are also possible.

[0057] In addition, the sensor housing 19 includes a cover 28 that forms a cover portion of the sensor housing 19 when the sensor housing 19 is in the retracted position (see...). Figure 3 (a), 4(a), 6(a), 7(a), and 8(a)), the cover flush-closes the corresponding openings in the respective panel members 12, 20. The cross-section of the cover 28 preferably corresponds to the cross-section of the covered (flush-closed) opening of the corresponding panel member, taking tolerances into account. Furthermore, the sensor housing 19 has at least one guide rod 30 (see... Figure 8 It is rotatably supported on, for example, the top frame structure 102 or another main structure.

[0058] The sensor housing 19 includes at least one transparent area 32 through which at least one environmental sensor 17, 18 can detect the vehicle environment. The respective transparent areas 32 of the environmental sensors 17, 18 are preferably permeable to the wavelength range in which the respective environmental sensors 17, 18 operate.

[0059] exist Figure 3 In this case, the sensor housing 19 includes three viewing areas 32, 32', and 32″ on the front housing portion 34. Two of the viewing areas, 32' and 32″, are positioned closer to the cover 28 on the sensor housing 19 or the front housing portion 34 relative to the third viewing area 32. The first environmental sensor 17 observes through two viewing areas 32' and 32″ to detect the vehicle environment. The second environmental sensor 18 observes through the third viewing area 32 to detect the vehicle environment.

[0060] According to the first exemplary embodiment, sensor modules 16 and 22 may include at least one environmental sensor 18, such as the lidar sensor described above. According to the first exemplary embodiment, sensor modules 16 and 22 may include only one viewing area 32, which is mounted as a window in the front housing portion 34 (see...). Figure 6 and 8 According to a first exemplary embodiment, sensor modules 16 and 22 are characterized in that motion system 24 is configured to move sensor housing 19 to a first deployed position (see...). Figure 4 (b), 5(a), 6(b), 7(b), 8(b)), which activates at least one environmental sensor 18 to detect the vehicle environment in a portion 35 of its field of view 36 (see Figure 7 (b)). Furthermore, the motion system 24 is configured to move the sensor housing 19 to a second deployed position, which activates at least one environmental sensor 18 to detect the vehicle environment throughout its entire field of view 36 (see [link]). Figure 7 (c)). A portion 35 of the field of view 36 has a smaller cone opening angle than the entire field of view 36. Therefore, the environmental sensor can only detect a portion of the vehicle environment. Other areas of the vehicle environment cannot be detected by the environmental sensor. Therefore, in this exemplary embodiment (see... Figure 6 and Figure 7 In its first deployed position, the environmental sensor 18 can selectively detect the vehicle environment. In this first deployed position, the sensor housing 19 is deployed relative to the panel members 12 and 20 such that only a portion of the transparent area 32 protrudes from the panel members 12 and 20 (see...). Figure 6 (b)). In the second unfolded position, the sensor housing 19 is unfolded relative to the panel members 12, 20, causing the entire transparent area 32 to protrude beyond the panel members 12, 20 (see...). Figure 6 (c)).

[0061] According to a second exemplary embodiment, sensor modules 16 and 22 may include the first and second environmental sensors 17 and 18 as described above. The first environmental sensor 17 may include, for example, two ultrasonic sensors. The second environmental sensor 18 may include, for example, a lidar sensor. According to a first exemplary embodiment, sensor modules 16 and 22 may include three viewing areas 32, 32', and 32'', which are respectively mounted as windows in the front housing portion 34 and spaced apart from each other (see...). Figure 3 According to a second exemplary embodiment, sensor modules 16 and 22 are characterized in that motion system 24 is configured to move sensor housing 19 to a first deployed position (see...). Figure 3 (b) and 5(a)), which activates the first environmental sensor 17 to detect the vehicle environment, and in this position the second environmental sensor 18 is preferably not activated, and the sensor housing 19 is moved to the second unfolded position (see 5(a)). Figure 3 (c) and 5(b)) activate the second environmental sensor 18 to similarly detect the vehicle environment. From Figure 5 (b) It can be seen that the field of view 36 of the first environmental sensor 17 overlaps with the field of view 36 of the second environmental sensor 18 at the second deployed position. The second deployed position preferably corresponds to the fully deployed position (see...). Figure 5 (b)). In this application, the field of view 36 of the environmental sensor 17 has a smaller cone opening angle compared to the second environmental sensor 18 (see Figure 5 (b) Therefore, in the first deployed position, only the first environmental sensor 17 is activated. On the other hand, in the second deployed position, the second environmental sensor 18 is also activated. Thus, selective activation of environmental sensors 17 and 18 is possible.

[0062] To move the sensor housing 19, the motion system 24 has a controller 38, which is configured, for example, to detect the current position of the sensor housing 19. The controller 38 is preferably configured to activate the first and / or second environmental sensors 17, 18 (see [link to relevant documentation]) based on their respective positions. Figure 8 (See diagram in (b)).

[0063] Reference Figure 8 According to any exemplary embodiment of the invention, the motion system 24 includes a slider 40. The drive device 26 preferably includes a drive gear (not shown). The drive gear or drive device 26 may be connected to the slider 40 in a force-transmitting manner via a spindle nut driver 42. Alternatively, a flexible shaft (not shown) may be provided on the drive gear. The drive device 26 is configured to move the slider 40 back and forth along a generally linear track via the spindle nut driver 42.

[0064] A groove 44 is provided in the slider 40, and a sliding pin 46 is supported in the groove 44 in a translational manner. The sliding pin 46 can be rigidly (immobile) arranged on the sensor housing 19. The slider 40 can be rigidly (immobile) mounted on the spindle nut 48 of the spindle nut driver 42. The spindle nut driver 42 also includes a spindle 50, which is rotatable relative to the spindle nut 48 to allow the driver 26 to move the spindle nut 48 and the slider 40 back and forth on the spindle 50.

[0065] Trough 44 includes a sloping section (see...) Figure 8 The drive unit 26 is configured to move the slider 40 so that the sliding pin 46 slides along the ramp-shaped portion. The slider 40 is configured such that the sliding pin 46 is preferably able to slide between a first stop position and a second stop position, the first stop position fixing the sensor housing 19, i.e., the environmental sensors 17, 18, in the retracted position (see...). Figure 8 (a)), second stop position (see Figure 8 (c) Secure the sensor housing 19, i.e., the environmental sensors 17 and 18, to the second deployed position. When the sensor housing 19, i.e., the environmental sensors 17 and 18, is in the first deployed position, the sliding pin 46 is placed in the intermediate area of ​​the ramp-shaped groove 44 (see...). Figure 8 (b) The movement of the spindle nut 48 along the spindle 50, driven by the drive unit 26, causes the slider to translate along the drive axis 52. Since the sliding pin 46 is fixed to the sensor housing 19, and the sensor housing 19 is rotatably but fixedly connected to, for example, the top frame structure 102 or another main structure via the guide rod 30, the relative movement of the slider 40 along the drive axis 52 causes the sliding pin 46 to move along the slot 44. This causes the sensor housing 19 to rotate about its axis of rotation 54, which is determined by the support points of the guide rod 30 and the top frame structure 102 or other main structure. Therefore, the sensor housing 19 (see...) Figure 8 (a) Move.
