Furthermore, most cars currently produced are equipped with intelligent in-vehicle terminals. To ensure a superior driving experience and to identify underlying issues early and mitigate risks, testing these in-vehicle terminals before a car enters the market becomes particularly important. Summary of the Invention

[0003] One of the purposes of this application is to provide a method, apparatus, equipment and system for testing vehicle-mounted terminals, which is used to simulate the sleep-wake-up and operation process of vehicle-mounted devices, so as to realize the testing of vehicle-mounted terminals.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] Based on the aforementioned technical means, the vehicle terminal testing method provided in this application addresses the main scenarios where vehicle terminal problems occur during vehicle power-on / off, sleep / wake-up, and prolonged use. This application combines wake-up testing, stress testing, and sleep testing to simulate the entire process of a vehicle from startup and operation to sleep during actual vehicle operation, thereby making the testing of vehicle terminals more realistic and improving the accuracy of the testing.

[0007] In one possible implementation, the above-mentioned vehicle-mounted terminal testing system further includes a programmable power supply and a relay. The integrated control device is connected to the vehicle-mounted terminal through the programmable power supply and the relay, respectively. The programmable power supply is used to power the test bench, and the relay is used to simulate the switching of the accessory (ACC) power supply.

[0008] Based on the above-mentioned technical means, this application provides a simulation test environment that simulates a real vehicle environment.

[0009] In one possible implementation, when the vehicle terminal is powered on for the first time, the wake-up test includes: sending a voltage adjustment control command to the programmable power supply to adjust the voltage from 0V to 12V; sending a power waveform control command to the programmable power supply, the power waveform control command including a preset power waveform, so that the programmable power supply can play back the preset power waveform, the preset power waveform being the power waveform on the vehicle terminal side when the actual vehicle is started; and sending a relay conduction command to the relay to connect the vehicle terminal.

[0010] Based on the above technical means, this application provides a test method for waking up the on-board terminal when simulating the initial power-on of a real vehicle, thereby simulating the voltage transformation of the whole vehicle during startup on the test bench.

Specifically, it simulates the scenario where the user unlocks the vehicle and then opens and closes the door before using the vehicle. Then, it simulates the power waveform of the random start-up to cover more vehicle terminal wake-up scenarios.

[0015] In one possible implementation, the aforementioned vehicle terminal testing system further includes a CAN box and a mobile terminal. The integrated control device is also connected to the vehicle terminal via the CAN box and the mobile terminal, respectively. The CAN box is used to simulate control signal playback, and the mobile terminal is configured with an application for generating a wake-up signal. When the vehicle terminal is not powered on for the first time, the wake-up test includes: sending a wake-up control command to the mobile terminal to generate a wake-up signal and send it to the CAN box; after the CAN box is woken up, sending a power waveform control command to the programmable power supply, the power waveform control command including a preset power waveform, to cause the programmable power supply to play back the preset power waveform, which is the power waveform on the vehicle terminal side when the actual vehicle starts; sending a simulated power-on command to the CAN box to cause the CAN box to send a simulated power-on signal to the vehicle terminal; and sending a relay conduction command to the relay to control the relay to connect the vehicle terminal.

[0016] Based on the above technical means, this application provides a test method for waking up the vehicle terminal in a scenario where the vehicle is not powered on for the first time. Specifically, it simulates a user accessing a telematics service provider (TSP) via a mobile terminal to wake up the vehicle terminal, and then covers more vehicle terminal wake-up scenarios by simulating random power waveforms.

[0017] In one possible implementation, the above-mentioned vehicle terminal testing system further includes a CAN box and multiple functional devices.

[0018] Based on the above technical means, this application provides a method for performing random operation tests and random function tests on the vehicle terminal after it is woken up, based on pre-collected real vehicle messages, to achieve stress testing on the vehicle terminal.

[0019] In one possible implementation, the above-mentioned vehicle terminal testing system further includes a microcontroller unit (MCU) serial port. The integrated control device is also connected to the vehicle terminal through the MCU serial port, which is used to monitor MCU printing.

[0021] In one possible implementation, the above-mentioned vehicle terminal testing method further includes: determining the sleep duration of the vehicle terminal, wherein the sleep duration is used to indicate the duration during which the vehicle terminal is in a sleep state; and executing the vehicle terminal testing process when the sleep duration is greater than a second preset duration.

[0022] Based on the above technical means, the vehicle terminal testing method provided in this application realizes the method of repeatedly performing wake-up, stress test and sleep test on the vehicle terminal after the vehicle is in sleep mode, so as to test whether the vehicle terminal will cause problems after long-term operation.

[0023] In one possible implementation, the above testing process also includes a device operation test, which is performed after the wake-up test; the device operation test is used to test whether the device connected to the vehicle terminal can operate normally.

[0043] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0052] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0053] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0054] In the description of the embodiments, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" and "more than one" refer to two or more. The terms "first," "second," etc., do not limit the quantity or execution order, and "first," "second," etc., do not necessarily imply that they are different.

[0055] Currently, with the booming automotive market, automobile production is increasing along with rising demand, and various automakers are releasing more and more new models. Furthermore, most cars produced at this stage are equipped with intelligent in-vehicle terminals. To ensure a superior driving experience and to identify underlying issues early and mitigate risks, testing these in-vehicle terminals before a car enters the market becomes particularly important.

[0056] Among related technologies, one approach involves using automated testing software to record operator actions, creating test cases, and then capturing or monitoring the on-board unit's display using a camera to determine the consistency with preset images. Another approach proposes that after a user inputs a start test command into a host computer, the system determines the intelligent vehicle terminal controller's state based on its battery level and controls a simulated sleep / wake-up state accordingly. This allows the intelligent vehicle terminal controller under test to be woken up from sleep mode based on the user-input test parameters.

[0057] Therefore, although related technologies provide testing methods for vehicle terminals, they all operate in response to user-programmed instructions, which cannot accurately reflect the actual situation and result in discrepancies between the test results and the actual operating results after the vehicle is put into use.

[0058] To address the aforementioned technical problems, this application proposes a method, apparatus, device, and system for testing vehicle-mounted terminals. The integrated control device is applied to an vehicle-mounted terminal testing system, which also includes a vehicle-mounted terminal. The integrated control device is connected to the vehicle-mounted terminal, and the vehicle-mounted terminal testing system is deployed on a test bench. The method includes: the integrated control device executing a testing process for the vehicle-mounted terminal, including wake-up testing, stress testing, and sleep testing. Furthermore, the integrated control device outputs test results, including the number of tests performed on the vehicle-mounted terminal, the test content, and the operating parameters.

[0059] Since the main scenarios where vehicle-mounted terminals malfunction are concentrated during vehicle power-on / off, sleep / wake-up, and prolonged use, the vehicle-mounted terminal testing method provided in this application combines wake-up testing, stress testing, and sleep testing to simulate the entire process of a vehicle from startup, operation to sleep during actual vehicle operation. This makes the testing of vehicle-mounted terminals more realistic and improves the accuracy of the testing.

[0060] Figure 1 This application discloses an in-vehicle terminal testing system. The in-vehicle terminal testing method provided in this embodiment can be applied to, for example, […]. Figure 1 The vehicle-mounted terminal testing system shown is used to simulate the sleep / wake-up and operation processes of vehicle-mounted devices, enabling testing of the vehicle-mounted terminal. For example... Figure 1 As shown, the vehicle terminal test system 10 includes an integrated control device 11, a vehicle terminal 12, a programmable power supply 13, a relay 14, a CAN box 15, a signal generator 16, an MCU serial port 17, a mobile terminal 18, a camera 19, a panoramic camera 110, an external instrument panel 111, and an automatic parking assist (APA) system 112.

[0061] The integrated control device 11 is connected to the vehicle terminal 12 via a programmable power supply 13, a relay 14, a CAN box 15, a signal generator 16, an MCU serial port 17, and a mobile terminal 18. The integrated control device 11 is also connected to the vehicle terminal 12 and a camera 19. The vehicle terminal 12 is connected to a panoramic camera 110. These connections can be wired or wireless; this embodiment does not limit the specific connection method. The vehicle terminal 12 is also connected to an external instrument cluster 111 and an APA system 112 via a CAN bus.

[0062] It should be noted that the vehicle-mounted terminal test system 10 is deployed on a test bench.

[0063] The camera 19 can be used to capture the display screen of the vehicle terminal 12 and transmit the acquired display screen to the integrated control device 12.

[0064] The integrated control device 11 can be used to control the programmable power supply 13 to supply power to the vehicle terminal 12 and monitor the current between the programmable power supply 13 and the vehicle terminal 12; it can also be used to control the programmable power supply 13 to supply power to the test bench.

[0065] The integrated control device 11 can also be used to control the relay 14 and to turn the ACC power supply of the simulated vehicle terminal 12 on and off.

[0066] The integrated control device 11 can also be used to control the CAN box 15 to send signals and simulate bus signals to wake up the vehicle system; it can also be used to control the CAN box 15 to play back signals for stress testing.

[0067] The integrated control device 11 can also be used to control the signal generator 16, simulate hard-wired signals, and key signals.

[0068] The integrated control device 11 can also be used to control the MCU serial port 17, print MCU logs, and monitor the sleep status of the vehicle terminal 12.

[0069] The integrated control device 11 can also be used to control the mobile terminal 18, simulating the user waking up the vehicle terminal 12 through a mobile application.

[0070] The mobile terminal wakes up the vehicle terminal 12 based on TSP.

[0071] The vehicle terminal 12 can be used to respond to the received signal and perform the corresponding operation.

[0072] For example, after receiving the simulated automatic parking signal sent by the signal generator 16, the vehicle terminal 12 calls the APA system 112 to run the automatic parking function.

[0073] For example, after receiving the simulated unlock signal sent by the CAN box 15, the vehicle terminal 12 performs the vehicle unlocking operation;

[0074] After receiving the simulated panoramic video signal sent by the CAN box 15, the vehicle terminal 12 activates the panoramic camera 110 and displays the image captured by the panoramic camera 110 on the vehicle terminal 12.

[0075] Figure 2 This is a flowchart illustrating a vehicle-mounted terminal testing method according to some exemplary embodiments. In some embodiments, the above-described vehicle-mounted terminal testing method can be applied to, for example... Figure 1 The vehicle-mounted terminal testing system 10 shown includes an integrated control device 11. Hereinafter, this application will describe the above data processing method using the integrated control device 11 as an example in the vehicle-mounted terminal testing method.

[0076] like Figure 2 As shown, the vehicle terminal testing method provided in this application includes the following steps S201-S202.

[0077] S201, Integrated control equipment executes the test procedure for the vehicle-mounted terminal.

[0078] The testing process includes wake-up testing, stress testing, and hibernation testing.

[0079] As one possible implementation, the integrated control device sequentially performs wake-up tests, stress tests, and sleep tests.

[0080] In some embodiments, the wake-up test during the initial power-on of the vehicle terminal includes:

[0081] The integrated control device sends a voltage adjustment control command to the programmable power supply, so that the programmable power supply adjusts the voltage from 0V to 12V.

[0082] Furthermore, the integrated control device sends power waveform control commands to the programmable power supply so that the programmable power supply can replay the preset power waveform.

[0083] The power waveform control command includes a preset power waveform, which is the power waveform of the on-board terminal when the vehicle starts.

[0084] Furthermore, the integrated control device sends a relay activation command to the relay, so that the relay connects to the vehicle terminal.

[0085] It should be noted that after the programmable power supply adjusts the power from 0V to 12V, the integrated control device sends a power waveform control command to the programmable power supply after a random delay of 1-10 seconds. Furthermore, within 0.5 seconds after the programmable power supply finishes playing back the preset power waveform, the integrated control device sends a relay conduction command to the relay to simulate the switching of the vehicle's power state to the ON state.

[0086] It should be noted that the preset power waveform can be set in advance by the maintenance personnel of the vehicle terminal test system in the integrated control device. The preset power waveform is collected in advance by the maintenance personnel at different power stages of the actual vehicle.

[0087] For example, 20 preset power waveforms were collected at temperatures of 25 degrees Celsius and -25 degrees Celsius, respectively, based on the remaining battery power of the vehicle at 10%, 20%, 30%, ..., 100%. When the integrated control device generates a power waveform control command, it randomly selects one from the preset power waveforms to send to the programmable power supply.

[0088] In some embodiments, when the vehicle terminal is not powered on for the first time, the wake-up test includes:

[0089] The integrated control device sends power waveform control commands to the programmable power supply so that the programmable power supply can play back the preset power waveform.

[0090] Furthermore, the integrated control device sends a relay activation command to the relay, so that the relay connects to the vehicle terminal.

[0091] It should be noted that this wake-up test is used to simulate the vehicle being directly woken up after power-off hibernation. Since the programmable power supply continues to output power, there is no need to integrate equipment to control the programmable power supply to adjust from 0V to 12V.

[0092] In some embodiments, when the vehicle terminal is not powered on for the first time, the wake-up test includes:

[0093] The integrated control device sends a bus wake-up command to the CAN box, so that the CAN box sends an unlock signal, a simulated door opening signal, and a simulated door closing signal to the vehicle terminal.

[0094] Furthermore, the integrated control device sends power waveform control commands to the programmable power supply so that the programmable power supply can replay the preset power waveform.

[0095] Furthermore, the integrated control device sends a simulated power-on command to the CAN box, so that the CAN box sends a simulated power-on signal to the vehicle terminal.

[0096] Furthermore, the integrated control device sends a relay activation command to the relay, thereby enabling the control relay to connect to the vehicle terminal.

[0097] It should be noted that this wake-up test simulates the CAN bus wake-up of the entire vehicle. The integrated control device controls the CAN box to send an unlock signal, simulating the process of a user unlocking the vehicle to wake it up. Further, based on simulated door opening and closing signals, the test simulates the process of a user unlocking and entering the vehicle. Subsequently, power waveform simulation and CAN bus signal transmission for vehicle power-on are performed randomly to closely resemble actual user scenarios.

[0098] Furthermore, after the integrated control device sends an unlock signal to the CAN box, it randomly delays for 0-10 seconds to control the CAN box to send a simulated door opening signal. Further, one second after sending the simulated door opening signal, the integrated control device controls the CAN box to send a simulated door closing signal. Further still, one second after the CAN box sends the simulated door closing signal, the integrated control device delays for 2 seconds before controlling the programmable power supply to replay a preset power waveform, and within one second after the programmable power supply replays the preset power waveform, it controls the CAN box to send a simulated power-on signal.

[0099] In some embodiments, when the vehicle terminal is not powered on for the first time, the wake-up test includes:

[0100] The integrated control device sends a wake-up control command to the mobile terminal, causing the mobile terminal to generate a wake-up signal and send it to the CAN box.

[0101] Furthermore, after the CAN box is woken up, the integrated control device sends a power waveform control command to the programmable power supply so that the programmable power supply can play back the preset power waveform.

[0102] Furthermore, the integrated control device sends a simulated power-on command to the CAN box, so that the CAN box sends a simulated power-on signal to the vehicle terminal.

[0103] Furthermore, the integrated control device sends a relay activation command to the relay, thereby enabling the control relay to connect to the vehicle terminal.

[0104] It should be noted that this wake-up test is a simulated TSP wake-up, specifically used to simulate a user issuing a remote start command via a mobile terminal and then starting the vehicle based on the remote start command.

[0105] In some embodiments, stress testing includes:

[0106] The integrated control equipment performs random operation tests on the vehicle terminal based on ADB.

[0107] Furthermore, after the first preset duration of random operation test, the integrated control device sends a random function test command to the CAN box, so that the CAN box can perform random function tests on the vehicle terminal.

[0108] It should be noted that the bus messages are collected in advance from the vehicle's onboard terminal, and for example, include 10 bus messages, each lasting 1 hour. The random operation test can be a monkey test.

[0109] In addition, the first preset duration can be set in advance by the maintenance personnel of the vehicle terminal testing system in the integrated control system, and this application embodiment does not specifically limit it.

[0110] For example, in the case of performing the panoramic video startup function during random functional testing, the CAN box sends a simulated panoramic video startup command to the vehicle terminal, so that the vehicle terminal responds to the simulated panoramic video startup command, starts the panoramic camera, and acquires panoramic video.

[0111] In the random function test where the voice command issuance function is executed, the CAN box sends a simulated voice assistant wake-up command to the vehicle terminal, so that the vehicle terminal responds to the simulated voice assistant wake-up command and starts the voice monitoring function.

[0112] In some embodiments, the hibernation test includes:

[0113] The integrated control device interrupts the stress test and sends an interrupt command to the CAN box to stop message playback and analog signal transmission, and sends an analog power-off signal to the vehicle terminal.

[0114] Furthermore, the integrated control device sends a relay interrupt command to the relay to cause the relay to disconnect.

[0115] Furthermore, the integrated control device sends a sleep command to the CAN box, so that the CAN box sends simulated door opening / closing signals and locking signals to the vehicle terminal.

[0116] Furthermore, when the CAN box monitoring bus activity stops, the programmable power supply monitoring current is less than the preset current, and the MCU serial port monitoring MCU printing stops, the integrated control device determines that the vehicle terminal enters a sleep state.

[0117] In some embodiments, in order to automatically simulate the long-term use scenario of a real vehicle, the integrated control device determines the sleep duration of the vehicle terminal, and executes the test process of the vehicle terminal if the sleep duration is longer than a second preset duration.

[0118] The sleep duration is used to indicate the length of time the vehicle terminal is in sleep mode.

[0119] It should be noted that the second preset duration can be set in advance in the integrated control device by the operation and maintenance personnel of the vehicle terminal testing system. The second preset duration can be set to a fixed value or a random value between 1 and 10 minutes. This application embodiment does not specifically limit this.

[0120] In some embodiments, the testing process further includes a device operation test, which is performed after the wake-up test. The device operation test is used to test whether the device connected to the vehicle terminal can operate normally.

[0121] S202, Integrated control equipment outputs test results.

[0122] The test results include the number of tests conducted on the vehicle-mounted terminal, the test content, and the operating parameters.

[0123] As one possible implementation, the integrated control device records the number of tests performed during the testing process for the vehicle-mounted terminal, as well as the test content and operating parameters of each device in each test. Furthermore, the integrated control device outputs the monitored test results.

[0124] Understandably, the vehicle terminal testing method provided in this application combines wake-up testing, stress testing, and hibernation testing to simulate the entire process of a vehicle from startup, operation to hibernation during actual vehicle operation, so as to make the testing of the vehicle terminal more in line with the actual situation and improve the accuracy of vehicle terminal testing.

If the number of resends exceeds 3, the integrated control device determines that the vehicle terminal has failed to wake up.

[0142] S343. When the integrated control device receives the engine start command in the CAN box, it controls the programmable power supply to play back the preset power waveform.

[0143] S344: Within 1 second after the programmable power supply plays back the preset power waveform, the integrated control device controls the relay to turn on and controls the CAN box to send a simulated power-on signal.

[0144] It should be noted that when the integrated control device executes the wake-up process, in the case of initial power-on, process 1 is used to wake up the vehicle terminal, and in the case of non-initial power-on, one of the wake-up processes, process 2, process 3 and process 4, is randomly selected to wake up the vehicle terminal.

The MCU serial port is used to monitor MCU printing. The on-board terminal testing system is deployed on a test bench. The programmable power supply powers the test bench, and the relays simulate the switching of the accessory ACC power supply. The on-board terminal testing device includes a processing unit and a transmitting unit. The processing unit is used to sequentially perform wake-up test, stress test and sleep test of the vehicle terminal; The processing unit is also used to output test results, which include the number of tests, test content, and operating parameters of the vehicle terminal. The processing unit is also used to perform random operation tests on the vehicle terminal based on the Android Debug Bridge (ADB). The sending unit is used to send a random function test command to the CAN box after the random operation test has run for a first preset time, so that the CAN box can perform random function tests on the vehicle terminal. The processing unit is also used to interrupt the stress test; The transmitting unit is also used to send an interrupt command to the CAN box so that the CAN box stops message playback and analog signal transmission, and sends an analog power off signal to the vehicle terminal; The sending unit is also configured to send a relay interrupt command to the relay so that the relay is disconnected; The transmitting unit is also used to send a sleep command to the CAN box, so that the CAN box sends a simulated door opening / closing signal and a locking signal to the vehicle terminal. The processing unit is also used to determine that the vehicle terminal enters a sleep state when the CAN box monitoring bus activity stops, the programmable power supply monitoring current is less than a preset current, and the MCU serial port monitoring MCU printing stops.
