Description

Area

[0001] The present disclosure relates to power tools and, more particularly, to power tools with exposed forming devices. background

[0002] ADAS (Advanced Driver Assistance Systems) are a group of safety features designed to improve driver safety and reduce the severity and frequency of traffic accidents. Today, an increasing number of new cars are equipped with advanced driver assistance systems (ADAS). It is estimated that more than half of all cars first registered in 2017 included at least one driver assistance system. The number of vehicles with ADAS, as well as the number of ADAS components, is expected to continue to increase significantly in 2020 and beyond. The growth of ADAS in vehicles is having a significant impact on auto repair shops.

[0003] In particular, any repair work related to the drivetrain or that somehow affects the vehicle's axles or height can affect ADAS operation. Such interference often renders previous sensor settings unusable. Even minor misalignments lead to error messages and cause the affected assistance systems to malfunction.

[0004] Thus, work, including maintenance and overhauls, repairs after traffic accidents or windshield replacements, and even work related to minor repairs, can affect radar and ultrasonic sensors and camera systems. Thus, ADAS recalibration may be necessary when replacing shock absorbers, struts, control arms, ball joints, tie rods, etc. In fact, ADAS recalibration may be necessary even if the only services performed are tire changes and wheel alignment.

[0005] As a result, workshops that typically provide services limited to non-electrical systems may be required to provide some level of ADAS recalibration. With the increasing standard fitment of ADAS systems on motor vehicles, the lack of the correct equipment to perform ADAS recalibration can jeopardize the continued operation of the facility.

[0006] However, current calibration tools are typically bulky and stationary, requiring the vehicle to be taken to an auto repair shop specializing in ADAS calibration. These units contain various electronic systems that make the units easy and precise to operate. For example, a calibration unit must be properly spaced from and aligned with a vehicle. Electronic measurement and alignment systems, which include electronics / lasers in the calibration device and targets attached to a vehicle's tires, offer an effective means of achieving the spacing and alignment requirements. However, such electronic systems increase the cost of the units. Consequently, maintaining such units is not worthwhile for smaller workshops, tire shops, or hobbyists.

[0007] In view of the above, it would be advantageous to provide an ADAS calibration system that is cost-effective. Furthermore, it would be advantageous to provide an ADAS calibration system that does not incorporate electronic systems within the unit itself to ensure that clearance and alignment requirements are met.

[0008] CN 111 310 943 A discloses a method and apparatus for calibrating an ADAS system, as well as vehicle diagnostic equipment. CN 2 10 322 327 U discloses a correlation alignment system for an ADAS calibration device. Brief description

[0009] The invention provides a mechanical ADAS calibration system as recited in claim 1 and a method for aligning a mechanical ADAS calibration system as recited in claim 4.

[0010] According to the invention, a mechanical ADAS calibration system comprises a target device, a wheel mount, at least one ADAS target configured for attachment to the target device, a plumb line, and a measuring tape extendable between the target device and the plumb line when at least one of the plurality of wheel mounts is attached to at least one wheel of a vehicle. In some embodiments, two wheel mounts are provided in the system. In other embodiments, four wheel mounts are provided in a system.

[0011] According to the invention, the mechanical ADAS calibration system comprises a tape measure hook attached to the target device and configured to couple to the tape measure when the tape measure is extended between the target device and the plumb line.

[0012] According to the invention, the mechanical ADAS calibration system comprises a further tape measure hook attached either to the target device or to a wheel mount. The tape measure is configured to couple to this tape measure hook and extend between the target device and the wheel mount when the wheel mount is attached to the vehicle.

[0013] According to the invention, the target device of the mechanical ADAS calibration system comprises a vertical rod and a horizontal rod movably mounted on the vertical rod. The horizontal rod includes a sliding groove extending horizontally along the horizontal rod, and a tape measure hook used with a wheel mount is attached to the target device by movably mounting the tape measure hook in the sliding groove.

[0014] In one or more embodiments, the wheel mount of the mechanical ADAS calibration system includes a body and two gripper arms extending outward from a first side of the body. One or more set screws are threadedly engaged with the body to assist in leveling the wheel mount. In some embodiments, a spirit level is attached to the body to further assist in leveling the wheel mount.

[0015] In one or more embodiments, the target device of the mechanical ADAS calibration system includes a base platform and two or more lockable wheels that support the base platform. Two or more target device set screws are threadedly engaged with the base platform to assist in leveling the wheel mount.

[0016] In one or more embodiments, a mechanical ADAS calibration system is aligned with a vehicle using vehicle-specific calibration system data, which in some embodiments is obtained using a readout device. According to the invention, the method comprises positioning a target device of the ADAS calibration system in front of a vehicle and moving a plumb line from a central location of the vehicle to a location on a surface below the vehicle. The distance between the plumb line and the target device is measured using a measuring tape extended between the target device and the plumb line. By comparing the obtained measurement value with the obtained vehicle-specific calibration system data, any discrepancy is identified, and the target device is then repositioned as desired.

[0017] In one or more embodiments, the method comprises coupling a measuring tape to a measuring tape attachment on the target device and measuring the distance between the plumb bob and the target device using the measuring tape coupled to the measuring tape attachment.

[0018] In one or more embodiments, the method includes positioning a wheel mount on a wheel of the vehicle and leveling the wheel mount to the wheel of the vehicle. Then, the tape measure is coupled to another tape measure positioned either on the wheel mount or the target device, and the distance between the wheel mount and the target device is measured. The target device is then repositioned as desired. In some embodiments, the correct distance between the wheel mount and the target device is obtainable from the vehicle-specific calibration system data.

[0019] In one or more embodiments, the method comprises positioning the tape measure used in measuring the distance between the wheel mount and the target device on a horizontal support of the ADAS calibration system at a predetermined location using the obtained vehicle-specific calibration system data. The tape measure is then coupled to the positioned tape measure to obtain the measured value between the wheel mount and the target device.

[0020] In some embodiments, a single wheel mount is used, and the wheel mount is moved between different wheels when the method includes obtaining additional measurements. In some embodiments, multiple wheel mounts are provided in the system, allowing multiple wheels to be coupled to wheel mounts during the alignment process. When multiple wheel mount measurements are used, in some embodiments, repositioning of the target device is guided by comparing the obtained measurements. Short description of the drawings

[0023] While various modifications and alternative forms are possible for the system described herein, specific embodiments thereof are shown by way of example in the drawings and will be described in detail herein. It is to be understood, however, that the system is not intended to be limited to the specific forms disclosed. On the contrary, the invention is intended to cover all combinations of features, modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.

[0024] With reference to Fig. 1, an ADAS calibration system 100 is shown. The ADAS calibration system 100 includes a target device 102, wheel mounts 104, and ADAS targets, which in the embodiment of Fig. 1 camera targets 106 and LASER / LIDAR reflectors 108. The ADAS calibration system 100 further includes adjustable measuring tape hooks 110, a plumb line 112 and a measuring tape 114. The target device 102, which is also shown in Fig. 2, comprises a base section 116 which has a wheel 120 (in Fig. 1, only two wheels 120 are shown) attached to a base platform 118. The actual number of wheels 120 varies according to the particular embodiment, with some embodiments having only two wheels, while other embodiments have three or more wheels. In some embodiments, the wheels are omitted. In the embodiment of Fig. 1, the wheels 120 are configured to swivel 360°, and at least two are lockable.

[0025] Four set screws 122 / 124 / 126 / 128 are threadedly engaged with the base platform 118 and are sufficiently long to raise the wheels 120 away from a surface below. In some embodiments, only three set screws are provided, while in other embodiments, more than four set screws are provided. In all cases, the set screws are of sufficient size and / or quantity to provide a stable platform for the ADAS calibration system 100, even if some of the wheels 120 are raised away from a surface below.

[0026] The base section 116 further includes two orthogonally mounted spirit levels 130 / 132 positioned centrally on the base section 116. A central tape measure hook 134 extends downwardly from the base platform 118.

[0027] The base section 114 is rigidly connected to a vertical support 140. In various embodiments, the vertical support 140 is constructed of plastic, fiberglass, and / or carbon fiber. The vertical support 140 is additionally or alternatively coated with a radiation-absorbing material. The materials and / or coating are selected to provide a reduced RCS (RADAR Cross-Section - effective retroreflective area) to reduce interference with RADAR / LIDAR calibration procedures. The vertical support 140 includes a measuring scale 142 positioned on a convenient side of the vertical support 140. A rack 144, which is part of a rack and pinion assembly 146, is fixedly attached to the vertical support 140.

[0028] A horizontal support 150 is movably connected to the vertical support 140 by the rack and pinion assembly 146. Two measuring scales 152 and 154 extend along the horizontal support. In some embodiments, there are no measuring scales on the horizontal support. In other embodiments, only the measuring scale 152 is provided. Each of the measuring scales 152 / 154 is associated with a respective sliding groove 156 / 158. In some embodiments, the sliding grooves 156 and 158 are identically sized and shaped. A RADAR / LIDAR target in the form of a reflective RADAR / LIDAR mirror 160 is attached to the horizontal support 150, and a crank 162, operatively connected to the pinion of the rack and pinion assembly 146, is rotatably supported by the horizontal support 150.

[0029] All wheel fastenings 104 of Fig. 1, one of which is also in Fig. 3 and Fig. 4 are identical in design. The wheel mounts 104 comprise a base 170 that supports two wheel gripping arms 172 / 174. A spirit level 176 is positioned centrally on the base 170, and a tape measure hook 178 extends from the base 170 on a side opposite the side from which the wheel gripping arms 172 / 174 extend. Two set screws 180 / 182 are threadedly engaged with the base 170. Although the system of Fig. 1 includes four wheel mounts 104, some embodiments provide more wheel mounts. Some systems provide only two wheel mounts.

[0030] All camera target objects 106 (in Fig. 1 and Fig. 5) include a body 184 and a carriage mount 186 sized to fit within the sliding groove 156. In some embodiments, the carriage mount 186 is elongated along the axis of the sliding groove 156 to provide fixed alignment of the camera target 106 with respect to the sliding groove 156. The carriage mount 186 is preferably configured to lock into a desired location within the sliding groove 156. The vehicle-facing side 188 of the camera target 106 is provided with a pattern used to calibrate a camera of a vehicle.

[0031] With further reference to Fig. 1, each of the LASER / LIDAR reflectors 108 includes a body 190 and a carriage mount 192 sized to fit within the sliding groove 158. In some embodiments, the carriage mount 192 is elongated along the axis of the sliding groove 158 to provide fixed alignment of the LASER / LIDAR reflectors 108 with respect to the sliding groove 158. The carriage mount 192 is preferably configured to lock at a desired location within the sliding groove 158. The vehicle-facing sides 194 of the LASER / LIDAR reflectors 108 are provided with a LASER / LIDAR reflective surface. The body 190, in some embodiments, is adjustably connected to the carriage mount 192 by a shaft 196. This allows a user to adjust the distance between the carriage mount 192 and the body 190.

[0032] With further reference to Fig. 1, each of the adjustable tape measure hooks 110 includes a body 198 and a carriage mount 200 dimensioned to fit within the sliding groove 156 and / or 158. In some embodiments, the carriage mount 200 is elongated along the axis of the sliding groove 156 / 158 to provide fixed alignment of the adjustable tape measure hook 110 with respect to the sliding groove 156 / 158. The carriage mount 200 is preferably configured to lock at a desired location within the sliding groove 156. The body 198 is configured for releasable coupling to an end portion of the tape measure 114. In some embodiments, the coupling is facilitated by the provision of a lip.

[0033] The measuring tape 114 may be any type of measuring tape. The measuring tape 114 includes an end portion 202 configured for releasable coupling to the body 198 of the adjustable measuring tape hooks 110 and to the central measuring tape hook 134 of the target device 102.

[0034] Fig. 6 and Fig. 7 show the ADAS calibration system 100 aligned with a vehicle 204. The ADAS calibration system 100 is, in one embodiment, configured using the Fig. 8 shown method 210, which with reference to Fig. 6 and Fig. 7. First, at block 212, vehicle-specific data for the vehicle 204 is obtained. Typically, a readout device, such as the readout device disclosed in U.S. Patent No. 8,886,391, issued November 11, 2014, the contents of which are incorporated herein by reference in their entirety, is used to obtain vehicle-specific information. This vehicle-specific data includes the required tire pressure, the required distance between the vehicle and the target device 102, the height of the horizontal support 150, and the position of the camera targets 106 / laser / lidar reflectors 108 along the horizontal support 150. For embodiments of the ADAS calibration system 100 that include adjustable tape measure hooks 110, the position of the adjustable tape measure hooks 110 along the horizontal support 150 is also provided.

[0035] After obtaining the vehicle-specific data, the vehicle is prepared and positioned according to the vehicle-specific data at block 214. Accordingly, in some embodiments, preparing the vehicle 204 includes inflating the tires to the correct pressure. Preferably, the vehicle 204 is positioned on a level surface.

[0036] At block 216, the wheel mounts 104 are positioned on the wheels of the vehicle 204. The wheel engagement arms 172 / 174 are extended to engage the wheels at a predetermined height for a particular wheel inflation pressure. In some embodiments, one or more of the wheel engagement arms 172 / 174 are adjustable based on the particular vehicle / tire combination. For adjustable wheel engagement arms, the required spacing of the wheel engagement arms is provided in the vehicle-specific data. The set screws 180 / 182 are used to level the wheel mounts using the level 176 with the wheel engagement arms 172 / 174 engaged with the wheel.

[0037] Next, at block 218, the plumb line 112 is positioned at a central feature of the vehicle 204. For example, vehicles typically include a central hood ridge or a central vehicle identification mark, or the like. By positioning the thread of the plumb line 112 at the central feature and lowering the plumb line 112 onto the surface supporting the vehicle, the front-most central point of the vehicle 204 is identified and transferred by the plumb line to a location on the surface 206 below.

[0038] The target device 102 is then positioned at the specific distance from the vehicle at block 220. The end portion 202 of the tape measure 114 is coupled to the central tape measure hook 134, and the distance from the target device 102 to the plumb line 112 is identified using the tape measure. In some embodiments, one or more of the wheels 120 of the target device 102 are locked to prevent the target device from being displaced by the tape measure 114. In embodiments with adjustable tape measure hooks 110, by pre-positioning the hooks to reflect the vehicle width, the adjustable tape measure hooks can be used as target sighting aids before and / or during the positioning of block 220. In particular, when the vehicle is aligned with the target device 102, the wheel tape measure hooks 178 and the adjustable tape measure hooks 110 are in line.

[0039] In any event, after the target device 102 has been positioned at the correct distance from the vehicle 204, the orthogonally mounted spirit levels 130 / 132 and the set screws 122 / 124 / 126 / 128 are used to level the base platform 118. (Block 222.) The wheels, particularly any wheels that remain in contact with the underlying surface 206, are typically locked at this point if they have not been previously locked.

[0040] The measuring tape 114 is then used to measure the distance from the measuring tape hooks 178 of each of the wheel mounts 104 to the adjustable measuring tape hooks 110 on the target device 102. (Block 224.) In some embodiments, the target device 102 includes fixed measuring tape hooks. While in the embodiment of Fig.1 Tape measure hooks are provided on both the target device 102 and the wheel mounts 104, in some embodiments, tape measure hooks are provided only on the target device, and in other embodiments, the tape measure hooks are provided only on the wheel mounts. In any of the above embodiments, the tape measure 114 is preferably coupled to either a tape measure hook on the target device or a wheel mount, and a measurement of the distance between the tape measure hook and a predetermined location on the other—the target device or the wheel mount—is obtained.

[0041] In any case, by comparing the measurements obtained on the left side of the vehicle 204 with the measurements obtained on the right side of the vehicle, it is possible to identify whether the target device 102 is correctly aligned with the vehicle 204. If the measurements match, the target device is correctly positioned and at the correct angle. If the measurements differ, the target device 102 is adjusted until the measurements match. The distance between the plumb line 112 and the target device 102 is checked after modifying the position of the target device 102.

[0042] Once the target device 102 is properly spaced and aligned, the target device 102 is configured to perform the ADAS calibration according to the vehicle-specific data. (Block 226) To this end, the horizontal height of the horizontal support 150 is set using the crank 162. The height is set by reference to the measuring scale 142 and / or using the measuring tape 114.

[0043] Furthermore, the camera targets 106 and the laser / lidar reflectors 108 are positioned based on the vehicle-specific data. The positions are determined using either the measuring scales 152 / 154 or the measuring tape 114. In embodiments that utilize adjustable measuring tape hooks 110, the camera targets 106 and the laser / lidar reflectors 108 can be positioned prior to aligning the target device 102. Alternatively, the adjustable measuring tape hooks 110 are removed after aligning the target device 102 to allow the positioning of the camera targets 106 and the laser / lidar reflectors 108 using the carriage mounts 186 / 192, and in embodiments with locking capability, to lock the carriage mounts 186 / 192 in the required locations.

[0044] The alignment method described above can be modified in various ways. For example, in embodiments where only two wheel mounts are provided, one side of the vehicle is measured when aligning the target device, and then the wheel mounts are repositioned to the opposite side of the vehicle to obtain the second measurement. Alternatively, in some embodiments, the required distance is provided between the wheel mount and the target device. Accordingly, the target device is typically correctly aligned as long as the distance to the plumb line and the distance to one of the wheel mounts are achieved. Furthermore, in some embodiments, the wheel mounts are not positioned until the target device has first been positioned.In addition, steps or sub-steps are performed in different orders in different embodiments.

[0045] The ADAS calibration system 100 is thus a completely mechanical system with mechanical measurement and adjustment procedures that allow the ADAS calibration system 100 to be manufactured inexpensively and easily used by a user. Once the ADAS calibration system 100 is properly configured, positioned, and aligned, the ADAS calibration is performed in any manner. In some embodiments, the readout device is used to initiate the calibration sequence. While the disclosure has been illustrated and described in detail in the drawings and the foregoing description, this should be considered as illustrative and not restrictive. It is to be understood that only the preferred embodiments have been set forth, and that all changes, modifications, and other applications that come within the spirit of the invention are also intended to be protected.
