[0061] Figure 2 A schematic diagram of a testing framework for the over-the-air download technology provided by an embodiment of the present disclosure.

[0062] In some embodiments, Figure 2 As shown, the stage frame 10 includes a main stage 21, a first slave stage 22 and a second slave stage 23, the main stage 21 and the first slave stage 22 are connected, and the first slave stage 22 and the second slave stage 23 are connected.

[0063] The stand frame 10 adopts a modular design and is assembled and constructed from a first material, a second material and a third material. For example, the first material may be an aluminum profile, the second material may be a sheet metal, and the third material may be an acrylic plate.

[0064] Optionally, the main stand and the first slave stand are connected, and the first slave stand and the second slave stand are connected, including: the main stand and the first slave stand are structurally connected via an angle plate, and the first slave stand and the second slave stand are structurally connected via an angle plate.

[0065] Specifically, the main stand 21 and the first slave stand 22 are structurally connected via an angle plate, and the first slave stand 22 and the second slave stand 23 are structurally connected via an angle plate.

[0066] An over-the-air download technology test framework provided by an embodiment of the present disclosure is structurally connected by a main frame and a first slave frame through an angle plate, and a first slave frame and a second slave frame are structurally connected through an angle plate, thereby improving the firmness of the test framework.

[0067] Figure 3 A schematic diagram of a testing framework for the over-the-air download technology provided by an embodiment of the present disclosure.

[0068] In some embodiments, Figure 3 As shown, the stand frame 10 also includes: casters 31, which are physically connected to the main stand 21, the first slave stand 22 and the second slave stand 23 respectively, and can be fixedly connected by bolts + nuts. In other embodiments, other connection methods such as welding can also be used.

[0069] Casters include movable casters, fixed casters and movable casters with brakes. Movable casters are also called universal wheels, and the structure of movable casters allows 360-degree rotation; fixed casters are also called fixed casters, and fixed casters do not have a rotating structure and cannot turn. Usually, the two types of casters are generally used in combination. For example, the structure of a trolley is two fixed wheels in the front and two universal wheels in the back near the push handle. Casters are made of various materials, such as PP casters, PVC casters, PU casters, cast iron casters, nylon casters, TPR casters, iron core nylon casters, iron core PU casters, etc.

[0070] The caster 31 is used to move the platform frame 10. Specifically, the caster can be a universal caster or a Fomar caster.

[0071] An over-the-air download technology test framework provided by an embodiment of the present disclosure uses casters to move the stand frame, which facilitates the replacement of the test framework site and improves the flexibility of the test framework.

[0072] Figure 4 A schematic diagram of a testing framework for the over-the-air download technology provided by an embodiment of the present disclosure.

[0073] In some embodiments, the stage frame 10 further includes: a preset number of layers.

[0074] Wherein, the height of each layer in the preset number of layers is determined by the volume size of the electronic control unit controller; the preset number of layers are vertically supported by the first material and laterally supported by the second material.

[0075] Specifically, Figure 4 As shown, when the preset number is 6, the rack frame has six layers from top to bottom, and the height of each layer is determined according to the volume of the electronic control unit controller. Figure 4 Each of the four upper layers has 36 reserved bus interfaces, which can carry 36 electronic control unit controllers, the fifth layer has 16 reserved bus interfaces, which can carry 16 electronic control unit controllers, and the sixth layer has 18 reserved bus interfaces, which can carry 18 electronic control unit controllers. Each of the six layers is supported vertically by the first material and horizontally by the second material. For example, the first material can be an aluminum profile, and the second material can be a sheet metal part.

[0076] In some embodiments, the rack frame 10 further includes: a power supply interface 41;

[0077] Wherein, the power interface is electrically connected to the relay controller LAN card, the control panel, and the electronic control unit controller respectively; the power interface is used to control the on and off of the power supply of the control panel and the electronic control unit controller.

[0078] Specifically, the power interface 41 is electrically connected to the relay controller LAN card 11, the control panel 12, and the electronic control unit controller 13 respectively. The power interface 41 is used to supply power to the control panel 12 and the electronic control unit controller 13, that is, the power interface 41 controls the on and off of the power supply of the control panel 12 and the electronic control unit controller 13.

[0079] In some embodiments, the gantry frame 10 further includes: a data interface 42;

[0080] Wherein, the data interface is connected to the control panel structure, and the data interface is also connected to the electronic control unit controller structure; the data interface is used to transmit signal data.

[0081] The data interface 42 is structurally connected to the control panel 12, and the data interface 42 is also structurally connected to the electronic control unit controller 13; the data interface 42 is used to transmit signal data. Exemplarily, the data interface can be a DB50 interface.

[0082] Specifically, a data interface 42 and a power interface 41 can be reserved on the right side of the main rack 21 and the left side of the second slave rack 23 to facilitate the expansion of the rack frame 10 in both directions. It can be understood that in other embodiments, the power interface 41 and the data interface 42 can be one interface, which can control the on and off of the power supply and transmit data.

[0083] A test framework for over-the-air download technology provided by an embodiment of the present disclosure reserves a data interface and a power interface, thereby facilitating expansion of the test bench framework in two directions, namely, adding an electronic control unit controller, thereby improving the coverage of the electronic control unit controller and enhancing the reliability of the test results of the over-the-air download technology.

[0084] Figure 5 A side view of a test framework for the over-the-air download technology provided in an embodiment of the present disclosure.

[0085] like Figure 5 As shown, the electronic control unit controller 13 is placed on the right side of the rack frame 10, and the relay controller local area network card 11 is placed on the left side.

[0086] In some embodiments, the relay controller LAN card is isolated from the outside world by the third material, the relay controller LAN card and the electronic control unit controller are separated by the second material, and holes are punched in the second material for wired connection.

[0087] Specifically, the relay controller LAN card 11 is isolated from the outside world by the third material to avoid dust and other pollution. The third material can be an acrylic plate. The relay controller LAN card 11 and the electronic control unit controller 13 are separated by a second material, and holes are punched in the second material for wired connection. The second material can be a sheet metal part.

[0088] In some embodiments, the relay controller LAN card is electrically connected to the bus, and the relay controller LAN card is electrically connected to the electronic control unit controller; the relay controller LAN card is also used to control the message frame data corresponding to the unique code of the controller LAN message frame, thereby controlling the on and off of the bus and the power on and off of the electronic control unit controller.

[0089] Specifically, the relay controller LAN card 11 is electrically connected to the bus, and the relay controller LAN card 11 is electrically connected to the electronic control unit controller 13. The relay controller LAN card 11 is controlled by the controller LAN signal, and the power supply of the electronic control unit controller 13 and each controller LAN and / or serial communication network line are controlled to be on and off through the relay controller LAN card 11. All relays occupied by each electronic control unit controller share a unique controller LAN message frame unique code, and the bus and power supply of the electronic control unit controller 13 are controlled to be on and off by controlling the different controller LAN message frame data corresponding to the unique controller LAN message frame code.

[0090] The control panel 12 is designed in the fifth row of the main frame 21. Figure 2As shown, the control panel 12 receives the controller area network message information, and then controls the on / off status of each electronic control unit controller 13 of the rack frame 10. The control panel 12 also includes all the controller area network and / or serial communication network interfaces of the entire rack bus architecture 14 in the rack frame 10, so that the user can lead out the bus signal for status detection during the monitoring process. It can be understood that the rack frame 10 is also provided with functional components such as a main control power switch and an emergency stop switch.

[0091] The electronic control unit controller 13 includes all controller branches of the vehicle platform. The user can pre-design and install the electronic control unit controller 13 at the corresponding position of the test bench. The various controller local area networks and / or serial communication network buses of the electronic control unit controller 13 are consistent with the corresponding positions. During testing, the electronic control unit controller 13 can be arbitrarily combined according to variable vehicle models by controlling the on and off of the relay controller local area network card 11 to simulate the actual vehicle environment.

[0092] The bus architecture 14 is constructed according to the electronic and electrical architecture of the vehicle platform corresponding to the test bench frame 10 to simulate the actual vehicle environment. It is understandable that in order to prevent signal interference, the Ethernet (Ethernet, Eth) signal can be switched on and off without passing through a relay.

[0093] An over-the-air download technology testing framework provided by the disclosed embodiment performs version comparison on the automobile controller before and after the over-the-air download technology, freely combines variable vehicle models, realizes fully automatic triggering and automatic management of version comparison results, improves the efficiency of version comparison, and thus improves the testing efficiency.

[0094] Figure 6 A flow chart of a test method for the over-the-air download technology provided by an embodiment of the present disclosure, such as Figure 6 As shown, the method includes the following steps:

[0095] S601: Obtain a test request for the over-the-air download technology.

[0096] Get an over-the-air test request.

[0097] The test request is obtained through the test equipment bench framework 10 .

[0098] S602: Perform vehicle model configuration according to the test request.

[0099] According to the above test request, the vehicle model is configured. Specifically, the locally maintained configuration ledger contains variable vehicle model information composed of different electronic control unit controllers, including the relay controller LAN card message frame unique code of each electronic control unit controller.

[0100] S603: When it is detected that the over-the-air download technology package is completed, the first test tool is called to control the rack framework to push the upgrade task.

[0101] When it is detected that the Over-The-Air technology (OTA) package is completed, the task scheduling platform is used. For example, the task scheduling platform can be Jenkins. Jenkins is an open source continuous integration (CI) tool that provides a user-friendly interface. It is mainly used for continuous and automatic building / testing of software projects, monitoring the operation of external tasks, automatically pushing OTA upgrade tasks to the test bench framework, and detecting the OTA upgrade status.

[0102] S604: Detect the success result of the upgrade test of the over-the-air download technology, where the success result of the upgrade test includes qualified and unqualified.

[0103] When the bench framework receives the OTA test task, the corresponding vehicle configuration table is read through the script in the bench framework, and the required relay controller LAN card message frame unique code is opened according to the vehicle configuration table, and the message frame unique code is completed according to the test requirements to form a complete controller LAN message to transmit the on / off information. The bench framework sends the completed controller LAN message to the bench framework through Ethernet, and the bench framework Ethernet to controller LAN module is transcoded and sent to the bench framework relay controller LAN card. The relay controller LAN card opens the corresponding relay according to the configuration table according to the message information transmitted by the controller LAN message. After the relay is turned on, the corresponding electronic control unit message is uploaded to the cloud. After the cloud detects the corresponding electronic control unit message, the OTA upgrade begins. The bench framework reads the cloud OTA upgrade status. When the OTA upgrade status is wrong or abnormal, the upgrade test success result is unqualified. The bench performs relay switch processing according to the script setting according to the OTA upgrade status to avoid failure. In this way, the upgrade test success result of the air download technology is determined, and the upgrade test success result includes qualified and unqualified. When the OTA upgrade status is normal, the upgrade test success result is qualified.

[0104] The disclosed embodiment implements version comparison testing and OTA upgrade testing through the testing method of over-the-air download technology, thereby improving the flexibility of the testing method of over-the-air download technology.

[0105] Figure 7 A flow chart of a test method for the over-the-air download technology provided by an embodiment of the present disclosure, such as Figure 7 As shown, the method includes the following steps:

[0106] S701: Obtain a test request for the over-the-air download technology.

[0107] Specifically, the implementation process and principle of S701 and S601 are the same, and will not be repeated here.

[0108] S702: Perform vehicle model configuration according to the test request.

[0109] Specifically, the implementation process and principle of S702 and S602 are the same, and will not be repeated here.

[0110] S703: When it is detected that the over-the-air download technology package is completed, the first test tool is called to control the rack framework to push the upgrade task.

[0111] Specifically, the implementation process and principle of S703 and S603 are the same, and will not be repeated here.

[0112] S704: Detect the success result of the upgrade test of the over-the-air download technology, where the success result of the upgrade test includes qualified and unqualified.

[0113] Specifically, the implementation process and principle of S704 and S604 are the same, and will not be repeated here.

[0114] S705: When the over-the-air download technology upgrade test is successful and the result is qualified, the vehicle computer is controlled to be turned on, and other electronic control unit controllers except the vehicle computer are controlled to be turned off.

[0115] When the over-the-air download technology upgrade test is successful, that is, the OTA upgrade is successfully completed, the test bench framework shuts down all electronic control unit controllers except the vehicle computer to simulate the sleep and wake-up process of the real vehicle.

[0116] S706: Open any other electronic control unit controller, perform remote diagnosis on the other electronic control unit controller, and obtain a diagnosis report.

[0117] After waking up from sleep mode, the OTA upgrade process relay is turned on again to remotely diagnose the electronic control unit controller corresponding to this OTA, and the message results and diagnosis results of the electronic control unit controller are uploaded to the cloud reporting platform, and the message results and diagnosis results are analyzed and archived.

[0118] In the embodiment of the present disclosure, if the upgrade test result through the over-the-air download technology is successful and qualified, a sleep wake-up test is performed on the electronic control unit controller, which further improves the flexibility of the test method of the over-the-air download technology.
