[0027] In order to make the person skilled in the art better understand the scheme of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0028] The ordinal numbers such as "first", "second", etc. used herein are only used to distinguish different parts with the same name, and do not represent a specific order or primary and secondary relationship, etc.

[0030] The test tool 1 provided by the embodiment is used for radar related test in the intelligent driving domain system, and the test tool 1 comprises a support 10, a first end plate 20A and a second end plate 20B, and the support 10, the first end plate 20A and the second end plate 20B can surround a box type structure with a closed cavity. The first end plate 20A and the second end plate 20B are oppositely arranged, the first end plate 20A is provided with a plurality of first mounting hole positions 21A for mounting radars, the second end plate 20B is provided with a plurality of second mounting hole positions 21B for mounting radars, the number of the first mounting hole positions 21A is the same as the number of the second mounting hole positions 21B, and the positions of the plurality of first mounting hole positions 21A and the plurality of second mounting hole positions 21B correspond to each other in one-to-one correspondence.

[0031] In the test environment of the intelligent driving domain system, the radars can be tested by using the test tool 1. In the application, a plurality of radars are mounted on the first end plate 20A, and a plurality of radars are mounted on the second end plate 20B. The number of radars mounted on the two end plates needs to be the same, and the positions of the radars mounted on the first end plate 20A correspond to the positions of the radars mounted on the second end plate 20B. The radars on the first end plate 20A can be controlled to emit waves, and the radars on the second end plate 20B can be controlled to receive waves, or the radars on the second end plate 20B can be controlled to emit waves, and the radars on the first end plate 20A can be controlled to receive waves. The position of the radar emitting waves can be calculated according to the received wave signals combined with the related algorithm of the domain controller, so as to determine whether the related algorithm of the domain controller is normal. The test tool 1 mounts the radars used for test on two opposite end plates, and the two opposite end plates can be connected to the support 10 to form a box type structure, which can greatly reduce the occupied space of the test tool 1, facilitate flexible arrangement of related hardware facilities during test, and also facilitate reduction of the required test site space, thereby being conducive to saving test cost.

[0032] Figure 1 and Figure 2 In the example shown in the figure, the first end plate 20A is provided with six first mounting hole positions 21A arranged in two columns; correspondingly, the second end plate 20B is also provided with six first mounting holes 21B arranged in two columns. In other implementations, the number and arrangement of the mounting hole positions on the two end plates can be set as required, and are not limited to those shown in the figure.

[0033] In some embodiments, the support 10 comprises a support body 11 and a cover plate 12 arranged in two parts. The support body 11 has a U-shaped structure, and comprises a bottom plate 111, a first side plate 112 and a second side plate 113 connected to opposite sides of the bottom plate 111. The cover plate 12 is buckled to the open end of the top of the support body 11.

[0034] In an application, the first end plate 20A can be arranged between one end of the first side plate 112 and the second side plate 113, and the second end plate 20B can be arranged between the other end of the first side plate 112 and the second side plate 113.

[0035] The bracket 10 adopts the above structure, which can connect and cooperate the first end plate 20A and the second end plate 20B with the bracket body 11, install the radar, and then buckle the cover plate 12, thereby facilitating the installation of the first end plate 20A and the second end plate 20B and the adjustment of the radar, and being also conducive to the maintenance of the bracket body 11 and the cover plate 12.

[0036] In other implementation schemes, the bracket body 11 and the cover plate 12 of the bracket 10 can also be fixedly connected.

[0037] In some embodiments, the first end plate 20A and the second end plate 20B are detachably connected and cooperated with the bracket 10.

[0038] In a specific implementation, the bracket body 11 includes opposite first and second ends, the first end plate 20A is detachably connected to the first end of the bracket body 11, and the second end plate 20B is detachably connected to the second end of the bracket body 11.

[0039] In actual application, the radar to be tested can have different types or different structures, and accordingly, the first mounting hole 21A of the first end plate 20A and the second mounting hole 21B of the second end plate 20B also match the setting of different types or different structures of radars, and the first end plate 20A and the second end plate 20B are detachably connected with the bracket body 11, thereby facilitating the selection of the first end plate 20A and the second end plate 20B matched with the radar to be tested, that is, the end plates corresponding to radars of different structures or types can share the bracket body 11 and the cover plate 12, which is conducive to cost saving.

[0040] In addition, according to the test requirement, the distance between the first end plate 20A and the second end plate 20B can be different, and the first end plate 20A and the second end plate 20B are detachably connected and cooperated with the bracket 10, so that different lengths of the bracket 10 can be replaced according to the test distance requirement.

[0041] For example, the distance between the first end plate 20A and the second end plate 20B is 30 cm, and the distance between the position for mounting the first end plate 20A and the position for mounting the second end plate 20B on the bracket 10 is 30 cm.

[0042] For example, the distance between the first end plate 20A and the second end plate 20B is 60 cm, and the distance between the position for mounting the first end plate 20A and the position for mounting the second end plate 20B on the bracket 10 is 60 cm.

[0043] In other implementations, the first end plate 20A and the second end plate 20B can also be fixedly connected with the rack body 11, so that the test tool includes a top-opened box-shaped structure and a cover plate 12.

[0044] The detachable connection of the first end plate 20A and the second end plate 20B with the rack body 11 of the support 10 can be in various ways.

[0045] Reference Figure 3 , Figure 3 is a side view of the rack body in a specific embodiment. In an implementation, a clamping groove 114 matching the first end plate 20A and the second end plate 20B can be arranged on the rack body 11, and the clamping groove 114 has a U-shaped structure. The first end plate 20A or the second end plate 20B can be inserted into the clamping groove 114 of the rack body 11 from the top opening of the rack body 11. This way is simple and reliable.

[0046] Two clamping grooves 114 are arranged at two ends of the rack body 11 respectively to be clamped and embedded with the first end plate 20A and the second end plate 20B respectively.

[0047] In a specific arrangement, the rack body 11 can be provided with more than three clamping grooves 114, which are arranged at intervals along the length direction of the rack body 11. The length direction of the rack body 11 is indicated by L in Figure 1 and Figure 3 . The overall length of the rack body 11 matches the maximum distance required for radar testing, so that one rack body 11 can be used to meet the radar testing requirements of different distances.

[0048] The number of clamping grooves 114 and the distance between adjacent two clamping grooves 114 can be set according to the different distance requirements of actual testing. For example, to meet the testing distance requirements of 30 cm and 60 cm, the rack body 11 can be provided with three clamping grooves 114 arranged at intervals along the length direction of the rack body 11, as shown in the orientation shown in Figure 3 , along the direction from left to right in the figure, the distance between the first clamping groove 114 and the second clamping groove 114 is 30 cm, the distance between the second clamping groove 114 and the third clamping groove 114 is 30 cm, and the second clamping groove 114 is located between the first clamping groove 114 and the third clamping groove 114. When the testing distance is 30 cm, the first end plate 20A and the second end plate 20B can be clamped and embedded with the first clamping groove 114 and the second clamping groove 114 respectively, or with the second clamping groove 114 and the third clamping groove 114 respectively; when the testing distance is 60 cm, the first end plate 20A and the second end plate 20B can be matched with the first clamping groove 114 and the third clamping groove 114 respectively.

[0049] In other embodiments, the first end plate 20A, the second end plate 20B and the rack body 11 can also be detachably connected in other manners. For example, outwardly protruding first lugs can be provided on the first side plate 112 and the second side plate 113 of the rack body 11, outwardly protruding second lugs can be provided on the two opposite sides of the end plate, and the first lugs and the second lugs can be connected by fasteners. For another example, connecting holes can be provided on the end faces of the rack body 11, and connecting posts that can be inserted into the connecting holes can be provided on the faces of the end plate facing the rack body 11; the connecting holes and the connecting posts can also be provided in reverse, i.e., the connecting holes are provided on the end plate and the connecting posts are provided on the rack body 11.

[0050] Please refer to Figure 4 and Figure 5 , Figure 4 for Figure 1 the partial structure of the first mounting hole of the first end plate in the first embodiment, Figure 5 the structure diagram of the radar in the specific embodiment.

[0051] The first mounting hole 21A and the second mounting hole 21B have the same structure. In some embodiments, the mounting hole includes a circular through hole to facilitate the insertion and fitting of the circular head of the radar 3.

[0052] The circular head of the radar 3 is generally provided with two symmetrically arranged connecting blocks 301, and the mounting hole can be provided with two clamping portions 211 that are clamped and fitted with the two connecting blocks 301 of the radar 3, so that the radar 3 can be reliably positioned after being inserted and fitted into the circular through hole.

[0053] Figure 4 and Figure 5 is only an example. In actual applications, mounting holes that match the specific shape and structure of the radar 3 can be provided on the end plate.

[0054] To avoid confusion between different types of radars 3, the radar 3 is also provided with a foolproof structure, and the mounting hole of the end plate can also be provided with a matching foolproof structure to prevent the installation of different types of radars 3 on the end plate from affecting the test.

[0055] The foolproof structure on the radar 3 can be a foolproof protrusion 302. Taking the example that the radar 3 is provided with two connecting blocks 301, the position relationship between the foolproof protrusion 302 and the two connecting blocks 301 is different. Taking the example shown in Figure 5 (a), in one type of radar 3 shown in Figure 5 (a), the foolproof protrusion 302 is close to the connecting block 301 on the right side, Figure 5 (b), in another type of radar 3 shown in (b), the circumferential distance between the foolproof protrusion 302 and the two connecting blocks 301 is the same.

[0056] The installation hole can be provided with a foolproof recess 212 matched with the foolproof protrusion 302 of the radar 3, and when the matched radar 3 is installed in the installation hole, the foolproof protrusion 302 of the radar 3 can be embedded in the foolproof recess 212 of the installation hole.

[0057] For example, the radar 3 can be an APA (Automatic Parking Assistant) ultrasonic radar or a UPA (Ultrasonic Parking Assistant) ultrasonic radar.

[0058] For reference Figure 6 , Figure 6 The structure of the bracket of the test tool provided in another embodiment of the application is shown.

[0059] In some embodiments, the inner surface of the cover plate 12 towards the bottom plate 111, the inner surface of the bottom plate 111 towards the cover plate 12, the inner surface of the first side plate 112 towards the second side plate 113, and the inner surface of the second side plate 113 towards the first side plate 112 are all provided with the wave-absorbing layer 13. In this way, the test can be prevented from being disturbed by other ultrasonic waves in the test environment, and the accuracy and reliability of the test results can be ensured.

[0060] The wave-absorbing layer 13 matched with each inner surface of the rack body 11 can be an integrated U-shaped structure.

[0061] In the scheme in which the rack body 11 is provided with more than three clamping grooves 114, the test tool 1 can also be provided with a U-shaped clamping strip matched with the clamping grooves 114. In application, if a clamping groove 114 is in a non-use state, the U-shaped clamping strip can be clamped in the clamping groove 114, and the inner surface of the U-shaped clamping strip is also provided with the wave-absorbing layer 13. In this way, the test can be prevented from being affected by the existence of the idle clamping groove 114.

[0062] In some embodiments, the cover plate 12 includes a cover body 121, and both sides of the cover body 121 are bent to form a folded edge 122 in the direction of the rack body 11. In the state that the cover plate 121 is buckled to the rack body 11, the two folded edges 122 are located outside the first side plate 112 and the second side plate 113, respectively. In this way, the position of the cover plate 12 can be limited by the cooperation of the folded edges 122 and the side plates, and in application, the cover plate 12 can be buckled on the rack body 11, which is convenient to operate.

[0063] The test tool 1 can also include a plug for plugging the first installation hole 21A or the second installation hole 21B. In actual test, there are situations in which some installation holes on the end plate are not used, and at this time, the plug can be used to plug these installation holes to prevent affecting the test.

[0064] For referenceFigure 7 , Figure 7 A structural block diagram of a test system in an embodiment provided by the present application is shown.

[0065] In addition to the foregoing test tool 1, the embodiment of the present application further provides a test system, which comprises the test tool 1, the domain controller 2 and a plurality of pairs of radars 3 introduced in the foregoing embodiments. Each pair of radars 3 is installed in the first mounting hole position 21A and the second mounting hole position 21B corresponding in position. The radars 3 are in communication connection with the domain controller 2. The domain controller 2 can control the radars 3 to emit or receive waves, and can acquire the wave receiving information to perform calculation according to the relevant algorithm stored in the domain controller 2.

[0066] The test system has similar technical effects to the foregoing test tool 1, and will not be repeated here.

[0067] In a specific implementation, the test system can further comprise a host computer 4, which is in communication connection with the domain controller 2. The host computer 4 can store or process the relevant information of the domain controller 2, and display the processing result.

[0068] The test system can be used for testing the intelligent driving domain system of a vehicle, and can be combined with other hardware or software to build a test environment for the intelligent driving domain system to simulate the actual driving condition of the vehicle.
