Description

[0001] Cross-references to related applications

[0002] This patent application claims priority to Italian patent application No. 102024000019939, filed on September 6, 2024, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] This invention relates to a vehicle service system.

[0004] More specifically, the present invention relates to a vehicle service system configured to perform vehicle service functions, such as measurement of vehicle components and / or calibration of sensors of a vehicle ADAS system and / or determination of vehicle wheel alignment, the system being explicitly referenced in the following description without any lack of generality. Background Technology

[0005] Vehicle service systems are known to be equipped with optical scanning devices that determine the position of a vehicle relative to a predetermined reference system within a service area based on the processing of predetermined captured images of the vehicle. These predetermined captured images are typically side images containing information related to a reference point of the vehicle, which are useful for detecting its position and are usually associated with axles and / or wheels, etc.

[0006] For example, a known vehicle service system is described in the applicant's European patent EP 4012328 B1. This system essentially involves using a series of optical reader devices arranged to face each side of the vehicle to capture its image.

[0007] Each optical reader device includes at its bottom: a rectangular support plate for the target, which rests on the surface of the service area; and a vertical housing that houses a binocular stereo vision system, which is typically equipped with two cameras.

[0008] One of the two cameras in a binocular stereo vision system has a field of view that frames targets to the side and below the vehicle.

[0009] The first technical problem encountered by the applicant is that the system is characterized by the particularly large size of the target support component.

[0010] In fact, the applicant has pointed out that in order to include the target in the field of view of the binocular stereo vision system, it must be placed far away from the vertical housing.

[0011] However, this distance results in a lateral band occupying the service area next to the vehicle, which prevents the positioning of other equipment required for diagnostics or calibration, and also affects the accuracy of the calibration.

[0012] The second technical problem encountered by the applicant is that the system is affected by reflections from ambient light sources, car windows, etc., which further affects the readability of the target.

[0013] The third technical problem encountered by the applicant is that the aforementioned system requires the use of a camera lens (optics) with an exceptionally wide field of view to simultaneously detect images of the wheel and the target. Due to the angular width, the optical solution introduces optical distortion that affects measurement accuracy, and eliminating or reducing this distortion requires the use of costly optical components or software image correction operations, the results of which are incompatible with the application in terms of accuracy. Summary of the Invention

[0014] Therefore, the object of the present invention is to provide a vehicle service system that overcomes the above-mentioned technical problems.

[0015] The appended claims describe preferred embodiments of the invention and form part of the specification. Attached Figure Description

[0023] Figure 7 It shows Figure 1 and Figure 2 The view shown is a perspective of the service system, with some components removed for clearer display. Detailed Implementation

[0024] refer to Figure 1 and Figure 2 The number 1 generally represents the vehicle service system.

[0025] According to a possible implementation, a vehicle servicing system 1 is used for vehicle 2. The vehicle servicing system 1 is configured to measure and / or control and / or calibrate vehicle 2 and / or its parts / components.

[0026] exist Figure 1 and Figure 2 In the example shown, vehicle 2 is temporarily (for the time required to perform maintenance operations) parked in service vehicle area 5, which has a surface plane P (ground) on which the wheels 3 of vehicle 2 rest at least temporarily during use. In the example shown herein, service vehicle area 5 has a central axis K ( Figure 2 ).

[0027] For example, plane P can correspond to a supporting surface, such as a horizontal supporting surface. The supporting surface can correspond to the floor / ground present in the vehicle service station 5, for example, within the workshop (not shown herein). Clearly, plane P can include any plane on which the wheels 3 of vehicle 2 rest.

[0028] Vehicle 2 can be a car (with an engine) or an electric vehicle. Figure 1 and Figure 2 In the example shown, the car has a longitudinal centerline A in the center and is provided with four wheels 3, which are connected in pairs to two corresponding axles (i.e., the front axle and the rear axle) of the vehicle 2. These two axles are transverse to the centerline A (i.e., orthogonal to the centerline A in the figure) and are separated from each other by a given distance (measured along the centerline A).

[0029] In the following description, the term wheel 3 refers to a common automobile wheel that includes at least a rim and a tire. Furthermore, the invention is not limited to automobiles, but can be applied to any type of motor vehicle equipped with any number of wheels and axles, such as trucks, vans, or buses having two or more axles and four or more wheels 3.

[0030] According to a possible implementation, the vehicle service system 1 is provided with a processing and control system 20, which is configured to determine a series of geometric parameters characterizing the vehicle 2 and / or its parts / assemblies based on a first image associated with a predetermined portion of the side / flank of the vehicle 2.

[0031] According to a preferred embodiment of the invention, the geometric parameters of the vehicle's components / assemblies may optionally involve: wheels 3 and / or axles and / or steering systems (not shown herein). The geometric parameters of wheels 3 may optionally include: the wheel's angle of attack or face, the wheel's camber angle, and the wheel's toe angle or toe plane. Angles or planes may preferably be determined relative to at least one predetermined (three-dimensional) reference system SR.

[0032] The geometric parameters of the wheels 3, which are used by the vehicle service system 1 to control, for example, the wheel alignment of vehicle 2, are known and will not be discussed further.

[0033] According to the present invention, the vehicle service system 1 includes a plurality of (at least two) optical reader devices 4, which are arranged on opposite sides of the service vehicle area 5 relative to the axis A of the vehicle 2 (or the axis K of the area itself) to ensure that they face opposite sides of the vehicle 2.

[0034] According to the present invention, the vehicle service system 1 further includes a plurality of (at least two) targets 8 arranged in the service vehicle area 5 adjacent to the corresponding optical reader device 4, thereby positioning the targets 8 on each side of the vehicle 2.

[0035] exist Figure 1 and Figure 2 The exemplary implementation shown and in the description below will refer to a vehicle service system 1 comprising four optical image reader devices 4 and four corresponding targets 8, but will not lack versatility for this reason.

[0036] exist Figure 1 and Figure 2 In the example shown, optical image reader devices 4 are arranged in pairs on opposite sides of the vehicle 2 in its transverse direction. In the example shown herein, the two optical image reader devices 4 are arranged on plane P. In the following description, for the sole purpose of increasing clarity of the invention, the example will be the case where the supporting plane P of the optical image reader devices 4 is substantially coplanar with the supporting plane of the vehicle 2, but this is not without its limitations. However, according to the invention, plane P cannot be coplanar and / or parallel to the supporting plane of the vehicle 2.

[0037] Optical image reader devices 4 are arranged in pairs to face two corresponding sides (flanks) of vehicle 2, which are parallel to each other on opposite sides relative to axes A and K. In the example shown herein, the optical image reader devices 4 are arranged in pairs to face two corresponding sides of vehicle 2 in a region approximately along the central axis of vehicle 2. However, the optical image reader devices 4 can also be arranged to face the wheels 3 of vehicle 2.

[0038] Reference Figures 3-7The optical image reader device 4 is provided with one or more optical image acquisition devices 9, which are configured to have their own field of view V1. Figure 7 It is configured to at least partially frame one side of vehicle 2 in order to first capture at least a portion of the image of that side itself.

[0039] According to the present invention, the optical image reader device 4 is further provided with a second optical image acquisition device 10, which is configured to have a second field of view V2 different from the field of view V1 and is configured to frame a target 8 near the optical reader device 4 in order to capture a second image containing the target 8.

[0040] The technical effect achieved by the optical image acquisition device 10 is to reduce the size of the target 8 and, on the other hand, to increase the accuracy of calibration. In fact, the arrangement and orientation of the optical image acquisition device 10 toward the target allows for a reduction in the distance between the target and the housing 11, thereby reducing its overall size in the plane. Furthermore, by positioning the optical image acquisition device 10 "facing" and above the target 8, potential image distortion can be reduced, thus improving the accuracy of the system, especially during calibration.

[0041] Reference Figures 3-7 According to the present invention, the target 8 is arranged adjacent to the optical image reader device 4 and is configured to be included in the field of view V2 of the optical image acquisition device 10.

[0042] Advantageously, the target 8 is arranged in close proximity to the associated optical image reader device 4, so that the target 8 is not included in the field of view V1 of the image acquisition device 9.

[0043] refer to Figures 3-6 According to a preferred embodiment, the optical image acquisition device 10 is also configured to exclusively frame the target 8 immediately below the optical reader device 4, thereby exclusively capturing a second image containing the target 8.

[0044] Conveniently, the optical image acquisition device 10 is configured such that its field of view V2 does not frame the vehicle 2 (e.g., its side / wing), thereby not capturing the first image.

[0045] refer to Figures 3-7 The optical reader device 4 includes a rectangular housing 11 extending along a generally vertical longitudinal axis B. In the example shown herein, the rectangular housing 11 forms a support column. Preferably, but not necessarily, the housing 11 may have a generally quadrilateral cross-section transverse to axis B to define four generally vertical sidewalls.

[0046] According to a preferred embodiment, target 8 has a planar shape and is arranged on a plane P that is substantially orthogonal to axis B. In the example shown herein, target 8 is substantially orthogonal to the sidewall 11a of housing 11 and is positioned adjacent to it. Target 8 is securely resting on plane P immediately adjacent to the lower end of the vertical sidewall 11a of housing 11.

[0047] Reference Figure 3 , Figure 5 and Figure 7 The optical image acquisition device 10 is securely fixed to the side wall 11a so as to protrude from it above the target 8 below, thereby facing the target 8. In the example shown herein, the optical image acquisition device 10 is arranged in the region at the upper end of the vertical side wall 11a of the housing 11.

[0048] Obviously, the present invention is not limited to positioning the optical image acquisition device 10 at the lower end of the housing. Alternatively, the optical image acquisition device 10 can be arranged below the upper end along the housing 11. For example, the optical image acquisition device 10 can be arranged at the middle axial position of the housing 11, or directly above the lower end at a certain height from the target 8, so that the second field of view V2 frames the target 8.

[0049] Preferably, the optical image acquisition device 10 may include a (digital) camera or camcorder or a similar image acquisition device. Figure 3 In the illustrated example, the optical image acquisition device 10 includes a box-shaped housing 13 formed by a cup-shaped body, which is securely fixed to the side wall 11a of the outer casing 11 and has a through-hole 13b facing the target 8 on the lower wall 13a facing the plane P. The optical image acquisition device 10 also includes a photosensitive electronic sensor 10a and an optical assembly 10b, both arranged within the housing 13. The optical assembly 10b is arranged within the cup-shaped body such that a lens faces the opening 13b, thereby enabling it to capture an image of the target 8 below.

[0050] Conveniently, the optical image acquisition device 10 also includes an illumination device 12 configured to project light or a beam of light onto the target 8 to illuminate / illuminate the target 8. In the example shown herein, the illumination device 12 includes a light source configured to emit light in the infrared spectrum. Conveniently, the light source may include one or more infrared light-emitting diodes, such as IRLEDs. Conveniently, the illumination device 12 is arranged in the housing near the optical assembly 10b on a plane generally parallel to the lower wall 13a, and facing a corresponding through-hole obtained on the lower wall 13a near the opening 13b.

[0051] Conveniently, the optical image acquisition device 10 is securely connected to the housing 11, such that its optical axis O1 forms an angle α of approximately 75° to approximately 105° with the laying plane of the target 8. Figure 3 ).

[0052] Reference Figures 3-7 The target 8 is integrated into and disposed thereon in a plate-like body 14. The plate-like body may comprise, for example, a thick plate, sheet, or plate made of a rigid material (e.g., metal or polymer). In the example shown herein, the plate-like body 14 has a quadrilateral shape, preferably a generally rectangular shape. Conveniently, the target 8 includes a two-dimensional (quadrilateral) image representing a predetermined (calibrated) pattern. In the example shown herein, the pattern comprises geometry containing circular graphic elements (circles) arranged at predetermined relative positions within the perimeter of the target 8, some of which are concentric.

[0053] The plate-shaped body 14 is securely arranged on the plane P near the outer casing 11, such that its target 8 is close to the lower end of the outer casing 11. Conveniently, the distance D1 between the target 8 and the outer casing 11 can be in the range of about 1 cm to about 5 cm, preferably 3 cm.

[0054] The rectangular outer shell 11 is configured to be selectively and detachably (separately) attached to the plate-like body 14.

[0055] Reference Figure 3 and Figure 7 The optical image acquisition device 9 includes at least two cameras 15 and 16, which are spaced vertically from each other along axis B within the housing 11, such that their respective optical components face one side of the vehicle 2. Conveniently, through-holes can be provided in the sidewall 11a of the housing 11 in the region of the optical components of the cameras 15 and 16 to allow them to capture a first image of one side of the vehicle 2.

[0056] exist Figure 3 In the example shown, cameras 15 and 16 are positioned in the middle of housing 11, both below optical image acquisition device 10. Conveniently, cameras 15 and 16 are arranged within housing 11 so as not to protrude from wall 11a, thereby not interfering with the field of view V2 of optical image acquisition device 10.

[0057] According to one possible embodiment (not shown), target 8 can be arranged adjacent to the vertical sidewall of housing 11 (except for vertical sidewall 11a on which the observation openings of cameras 15 and 16 are arranged). In this case, optical image acquisition device 10 is arranged on the same wall facing / adjacent to target 8. For example, target 8 can be arranged adjacent to the rear vertical wall of housing 11 opposite sidewall 11a (shown in the figures), and optical image acquisition device 10 can be fixed to the same rear wall above target 8. Obviously, target 8 can be arranged adjacent to any of the other remaining vertical walls, and optical image acquisition device 10 can be securely attached to the same wall above target 8.

[0058] The optical image reader device 4 may also include at least one additional target 30, which is fixed to the side wall of the housing 11 facing the calibration device 6.

[0059] Conveniently, the optical image acquisition device 9 may include an illumination system 18 configured to generate light or a beam converging toward one side of the vehicle 2 to illuminate / illuminate an area of ​​the vehicle 2 included in the field of view V1. In the example shown herein, the illumination device 18 includes a light source configured to emit light in the infrared spectrum. In the example shown herein, the light source may include an infrared light-emitting diode, such as an IR LED, arranged in the region of a through-hole obtained in the vertical wall 11a within the housing 11. Conveniently, the light source of the illumination system 18 may be arranged in the region of an opening obtained in the wall 11a immediately adjacent to the optical components of the associated camera 15 or 16. Cameras 15 and 16 cooperate with the processing and control system 20 to implement a binocular stereo vision method, thereby providing a first image. The operation of a binocular stereo vision method that uses two cameras to construct a 3D image associated with the first image is known and will not be described further.

[0060] The optical image reader device may also include a lighter device 31 arranged along the housing 11 between cameras 15 and 16 and designed to project light onto the surface of the vehicle 2 included in the field of view V1. The purpose of the structured laser is to improve the three-dimensional detection of the wheel 3.

[0061] The housing 11 may also have a handle, for example, at the rear. Figure 4 It also has lower wheels that rest on the ground.

[0062] Reference Figures 3-7 The outer casing 11 has a plate-shaped base 19 at its lower end, which is provided with a connecting element 21 that protrudes from the lower surface of the base 19 and is parallel to the axis B.

[0063] In the example shown herein, the plate-like body 14 supporting the target 8 is provided with a through hole 26 parallel to axis B. This through hole 26 is designed to accommodate the connecting element 21 and is provided with a locking / unlocking device 22. This locking / unlocking device 22 is configured to lock or alternatively unlock the connecting element 21 of the housing 11 when the plate-like body 14 of the housing 11 rests on the plate-like body 14 and the connecting element is inserted into the corresponding hole 26. Figure 6As shown, the locking / unlocking device 22 may include two plates 24 and 25, each having corresponding holes 27 axially aligned with a through hole 26 to accommodate a connecting element 21 in use. Plate 24 is securely fixed to the plate-like body 14, while the other plate 25 is mounted to slide freely between the inner surfaces of plate 24 and plate-like body 14 between an unlocked and a locked position. In the unlocked position, plate 25 allows the connecting element 21 of the housing 11 to be withdrawn from the holes 26 and 27, while in the locked position, plate 25 retains the connecting element 21 axially engaged in the associated holes 26 and 27. Conveniently, the connecting element 21 may include a cylindrical body provided with an annular groove 28, and the hole 27 of the sliding plate 25 may be formed with a tab 29. When plate 25 is in the locked position, the tab 29 engages the annular groove 28, thereby engaging the cylindrical element and axially locking it; and conversely, when plate 25 is in the unlocked position, the tab 29 disengages from the annular groove of the connecting element 21.

[0064] According to possible implementations, the electronic processing and control system 20 can be configured to optionally perform adjustment and calibration operations to be performed on the optical image reader device 4 based on a second image containing the target 8.

[0065] Based on the operation disclosed and shown in the applicant’s European patent EP 4012328 B1, the electronic processing and control system 20 can advantageously implement regulation and calibration, the contents of which (specification and drawings) are fully incorporated herein by reference.

[0066] According to a preferred embodiment of the invention, the processing and control system 20 can also be configured to determine the position of vehicle 2 relative to a predetermined reference system SR within the service vehicle area 5. Conveniently, the processing and control system 20 is capable of determining the position of vehicle 2 relative to the predetermined reference system SR based on a first image associated with predetermined portions of the side / flank of vehicle 2 (e.g., axles and / or wheels 3). Determining the position of vehicle 2 relative to the predetermined reference system SR based on the first image can advantageously be implemented by the electronic processing and control system 20 based on the operation disclosed and shown in the applicant's European Patent EP 4012328 B1, the contents of which (specification and drawings) are fully incorporated herein by reference.

[0067] The electronic processing and control system 20 can also be configured to cooperate with the optical image reader device 4 and the target 8 to implement methods for measuring and / or controlling the vehicle 2 and / or its components / assemblies. The methods for measuring and controlling the vehicle 2 and / or its components / assemblies can advantageously be implemented by the electronic processing and control system 20 based on a first image, which implements, for example, the operations disclosed and shown in the applicant's European Patent EP4012328B1, the contents of which (specification and drawings) are fully incorporated herein by reference.

[0068] refer to Figure 1 and Figure 2 The vehicle service system 1 preferably, but not necessarily, also includes a calibration device 6 configured to calibrate electronic sensor devices, hereinafter referred to as Advanced Driver Assistance System (ADAS) sensors, which are included in the Advanced Driver Assistance System 100 (ADAS system) of the vehicle 2 parked in the service area 5. The calibration device 6 may be located in the service area 5 in front of and / or behind the vehicle 2.

[0069] The calibration device 6 is designed to move within a service area 5 on a support plane P and includes one or more calibration devices 6a, which are designed to be detected by the corresponding ADAS sensors of the ADAS system 100 of the vehicle 2 during the calibration of the ADAS sensors.

[0070] According to a preferred embodiment, the electronic processing and control system 20 is configured to determine the position of the calibration device 6 and / or the first position of the calibration device 6a relative to the vehicle 2 based on first data indicating the position of the vehicle 2 in the service vehicle area 5 relative to a predetermined reference system SR and second data indicating the position of the calibration device 6 relative to the predetermined reference system SR.

[0071] According to a preferred embodiment, the vehicle service system 1 may include a position detection system comprising at least two or more optical devices 4 and two cameras 6b, which are mounted on a calibration device 6 and arranged in a lateral position relative to opposite sides of the calibration device 6a.

[0072] Two cameras 6a are optically oriented toward an optical device to capture a third image of the target 30 containing the optical reader device 4.

[0073] According to a preferred embodiment, the processing and control system 20 is configured to determine first data based on a first image and second data based on a third image.

[0074] According to a preferred embodiment, the processing and control system 20 is configured to determine a first position indicating the position of the calibration device 6 and / or the position of the calibration device 6a relative to the vehicle 2 based on the first image and the third image.

[0075] Conveniently, the processing and control system 20 is configured to determine a first position indicating the position of the calibration device 6 and / or the position of the calibration device 6a relative to the vehicle 2 by implementing operations such as those described in European patent application EP 4050303 A1.

[0076] The vehicle service system 1 also includes a communication system (not shown), preferably a wireless system, which is configured to exchange data and / or information and / or images between the optical image reader device 4 and / or the processing and control system 20 and / or the calibration device 6.

[0077] In use: The plate-shaped body 14 supporting the target 8 is firmly fixed in a relative position on the plane P (i.e., on opposite sides of the vehicle 2), and the optical image reader device is securely but detachably connected to the corresponding plate-shaped body 14. When the housing 11 is connected to the relevant plate-shaped body 14, the axis B is approximately vertical, and its optical image acquisition device 10 is arranged above the target 8 to frame it.

[0078] When the vehicle service system 1 performs the function of calibrating the optical image reader device 4: the optical image acquisition device 9 provides corresponding data / signals encoding at least partially containing one or more images of the opposite sides of the vehicle 2; the electronic processing and control system 20 processes the data / signals to determine / build one or more three-dimensional images related to the vehicle 2 and / or components of the vehicle 2; the optical image acquisition device 10 captures one or more images of the target 8 below to provide corresponding data / signals encoding the image of the target 8; the electronic processing and control system 20 performs the calibration of the optical reader device 4 at least based on the image of the corresponding target 8.

[0079] When the vehicle service system 1 determines the position of the calibration device 6 relative to the predetermined reference system SR: the optical device 8 captures a first image containing an image of the vehicle 2; the camera 6b captures a third image containing a target 30 of the optical device 4; based on the first and third images, the processing and control system 20 determines a first position indicating the position of the calibration device 6 and / or the position of the calibration device 6a relative to the vehicle 2.

[0080] The processing and control system 20 can also automatically guide the movement of the calibration device 6 and / or the movement of the calibration apparatus 6a to a predetermined calibration position based on the determined first position.

[0081] The processing and control system 20 is also designed to determine a spatial reference plane for detecting the position of vehicle 2 in the service vehicle area 5 based on the image of target 8.

[0082] In use, the target 8 is positioned, for example, by using a template provided to the installer during the installation of the plate 14. After the target 8 is installed, the vehicle service system 1 performs the aforementioned calibration operation to accurately determine the position of each target 8, thereby providing spatial coordinates to the processing and control system 20.

[0083] The aforementioned system has the advantage of allowing the target 8 to be positioned close to the outer casing. Furthermore, the positioning of the optical image acquisition device 10 on the outer casing above the target determines the increase in system accuracy.

[0084] The system also has the advantage of increasing target readability because the optical image acquisition device 10 positioned above the target 8 essentially eliminates the effect of reflections caused by ambient light.

[0085] The aforementioned system also has the advantage of eliminating the need for expensive lenses (optics) in cameras with exceptionally wide angles of view to simultaneously detect wheels and targets. Because of this, the system allows for the elimination of optical distortion without requiring costly optical components and / or specific software correction operations, thus conveniently reducing the system's manufacturing cost.
