It can be understood that the specific embodiments described herein are only for explaining the present disclosure, rather than limiting the present disclosure. Additionally, it should be noted that for the convenience of description, only the parts related to the present disclosure rather than all the structures are shown in the drawings.

[0032] Embodiment 1

[0033] Figure 1 The following is a schematic structural diagram of an automated test system provided in Embodiment 1 of the present disclosure. This embodiment is applicable to testing the seat heating system in a vehicle, and solves the problems of high test cost, long time, and poor repeatability in testing the seat heating system in the existing solutions. This system can be integrated in an electronic device, and the electronic device can be a PC terminal or a server, etc. This system can be configured in a computing device. The automated test system provided in this embodiment specifically includes the following:

[0034] As Figure 1 shown, the automated test system (hereinafter referred to as the test system) includes:

[0035] The upper computer subsystem, the virtual simulation device, and the test platform for the seat heating control system; wherein,

[0036] The upper computer subsystem communicates with the virtual simulation device, and is used to input power parameters, network signal parameters, and temperature sensor parameters during the simulated seat heating process, generate a test sequence according to the input parameters, and send the test sequence to the virtual simulation device.

[0037] Among them, the power parameters can be the power voltage value and the power current value during the seat heating process. The network signal parameters can be understood as the surrounding network environment information during the seat heating process. The temperature sensor parameters can be the temperature sensor parameters set in the seat heating system, and are used to indicate the temperature information during the seat heating process. The test sequence can be understood as a sequence for performing simulation.

[0038] Specifically, the upper computer subsystem and the virtual simulation device can be communicatively connected via Ethernet. For example, a corresponding wireless communication module can be set in the upper computer system. The upper computer subsystem and the virtual simulation subsystem can perform data transmission based on the wireless communication module. The upper computer subsystem and the simulation subsystem can also be connected via a bus. When connected via a bus, each subsystem exchanges information via the bus. When a user needs to use the automated test system to perform an automated test on the seat heating control system, the power supply parameters, network signal parameters, temperature sensor parameters, etc. during the operation of the seat heating control system can be input into the upper computer subsystem of the automated test system. The upper computer subsystem generates a corresponding test sequence based on the input parameters and sends the test sequence to the virtual simulation device based on a preset communication method.

[0039] In the technical solution of this embodiment, by inputting the parameter information during the operation of the seat heating control system when the user needs to use the automated test system, the upper computer subsystem can generate a corresponding test sequence based on the input information, enabling the virtual simulation device to perform an automated test based on the test sequence, realizing the automated test of the seat heating control system and improving the test efficiency.

[0040] Based on the above technical solution, the upper computer subsystem includes: a test database module and a test sequence module; wherein, the test database module is used to store test parameters under various test conditions and, when receiving a test request, determine the target test parameters corresponding to the current test condition from the various test parameters; the target test parameters include power supply parameters, network signal parameters, and the temperature sensor parameters; the test sequence generation module is used to generate a test sequence to be sent to the virtual simulation device according to the target test parameters.

[0041] Among them, the test condition can be understood as various working conditions that need to be tested. The test parameters can be vehicle parameters corresponding to the vehicle under various conditions. The vehicle parameters can include parameters such as the height parameter of the vehicle body, speed parameter, engine speed parameter, power supply parameter, network signal parameter, and the temperature sensor parameter. The test request can be a request sent by the user by triggering an interaction button in the upper computer subsystem.

[0042] Specifically, vehicle parameter information under various working conditions can be collected in advance and stored in the test database module of the upper computer subsystem. For example, vehicle parameter information under various working conditions can be collected based on various sensors set on the vehicle. After the vehicle parameter information is collected, it is uploaded to the cloud. When the user needs to conduct a simulation test, the required vehicle parameter information can be downloaded from the cloud. It can also be the vehicle parameter information set by the user according to requirements before the simulation test. For example, the parameter information of the vehicle working in an extreme working environment. It can be understood that different working conditions correspond to different parameter information. A comparison table can be set in advance to store the parameter information corresponding to different working conditions correspondingly. Furthermore, when the user needs to use the automated test system in this embodiment, the working condition to be tested can be freely selected. The upper computer subsystem searches for the parameter information corresponding to the working condition information from the test database module according to the working condition information selected by the user. For example, the corresponding parameter information can be found in the comparison table according to the working condition selected by the user. Then, the test sequence generation module generates a corresponding test sequence based on the parameter information and sends the generated test sequence to the simulation test device.

[0043] It should be noted that the upper computer subsystem can be an intelligent device with data storage function, data processing function and capable of sending control instructions, such as a computer, etc. On the one hand, the upper computer subsystem in this embodiment is used to determine the corresponding vehicle parameters based on the working condition information selected by the user, construct a corresponding test sequence based on the parameter information, and send the test sequence to the virtual simulation test device. On the other hand, it can also be used to receive the test request sent by the user. By increasing the number of test working conditions in this embodiment, the problem of single traditional test working condition is avoided, and the parameter selection and the automated test of the seat heating control system can be automatically completed based on the working condition information selected by the user, saving human resources and improving the test efficiency.

[0044] The virtual simulation device is used to receive the test sequence sent by the upper computer subsystem, generate a simulation signal based on the test sequence, and send the simulation signal to the seat heating control system test platform.

[0045] Among them, the simulation signal can be used to instruct the seat heating control system test platform to conduct corresponding simulation tests.

[0046] Specifically, after receiving the test sequence sent by the upper computer subsystem, the virtual simulation device can generate a corresponding simulation signal based on the received test sequence and send the test signal to the seat heating control system test platform, so that the seat heating control system test platform conducts a simulation test on the seat heating control system according to the simulation signal.

[0047] Based on the above technical solutions, the virtual simulation device includes: a power control model, a seat heating output acquisition model, a seat temperature sensor simulation model, and a seat temperature acquisition model; wherein, the power control model is used to provide the voltage and current required by the seat heating controller according to the simulation signal; the seat temperature sensor simulation model is used to simulate the resistance value of the seat temperature sensor corresponding to the simulation signal; the seat heating output acquisition model is used to collect the control signal output by the seat heating controller for heating, so as to collect the duty cycle and frequency; the seat temperature acquisition module is used to collect the seat surface temperature; wherein, the seat surface temperature includes the seat temperature with and without a user; based on the information collected by each model, the simulation signal is generated.

[0048] Among them, the seat heating controller can be a controller for controlling the vehicle seat heating system. For example, the seat heating controller can be a single-chip microcomputer. The voltage and current can be understood as the voltage value and current value when the seat heating controller is working. The seat temperature sensor can be a sensor for collecting seat temperature information. It should be noted that the temperature sensor detects the resistance value of the temperature-sensitive resistor and obtains the corresponding temperature information according to this resistance value. Therefore, the resistance value can be understood as the resistance value of the temperature-sensitive resistor at the current temperature. The control signal can be understood as the control information output by the seat heating controller for controlling the seat heater. The duty cycle can be the proportion of the energization time relative to the total time within a pulse cycle of the control signal. Correspondingly, the frequency can be understood as the number of times the control signal completes a periodic change within a unit time. Generally, the unit time is 1 second. The seat surface temperature can be the temperature of the surface of the vehicle seat.

[0049] Specifically, the power control model in the virtual simulation device provides the working voltage value and working current value for the seat heating controller according to the simulation signal. It can be understood that in order to meet the needs of users, the seat heating control system installed on the vehicle usually sets multiple heating modes. The working voltage and working current of the seat heating controller are different under different heating modes. Therefore, the power control model can provide different working currents and working voltages for the seat heating controller according to the simulation signal. The seat temperature sensor simulation model can simulate the resistance value of the corresponding seat temperature sensor according to the simulation signal, and then the seat temperature under the current working condition can be determined according to this resistance value. The seat heating output acquisition model collects the control signal sent by the seat heating controller during operation and analyzes the collected control signal to obtain the corresponding duty cycle and frequency information. The temperature acquisition module collects the temperature information of the seat surface. It can be understood that due to the different usage states of the vehicle seat, the seat temperature information in the used state and the unused state is different. After the required information is collected by each model, the corresponding simulation signal is generated according to the collected information.

[0050] Based on the above technical solution, the virtual simulation device further includes: the thermal imaging acquisition system, which is the same as the thermal imaging system, and is used to acquire the thermal imaging data and generate a thermal map based on the thermal imaging data; wherein, the thermal map corresponds to the temperature signal.

[0051] Among them, the thermal imaging data can be the heat information collected by a corresponding thermal imaging device. It can be understood that the thermal imaging device can detect infrared energy (heat) non - contact and convert it into an electrical signal, and then generate a thermal image and temperature value on a display. The thermal map can be the image information generated based on the thermal imaging data.

[0052] Specifically, the heat information of the vehicle seat heating system can be collected by the thermal imaging acquisition system set in the virtual simulation device, and the corresponding thermal imaging data can be generated, and the corresponding thermal map can be generated based on the thermal imaging data. It can be understood that the image areas in the thermal map may have different colors, and according to the different regional temperatures, the corresponding colors are also different.

[0053] The seat heating control system test platform communicates with the virtual simulation device, and is used to receive the simulation signal sent by the virtual simulation device, heat the seat system based on the simulation signal, and obtain the heating control signal and temperature signal of the seat system based on the virtual simulation device.

[0054] Among them, the heating control signal can be the heating signal sent by the seat heating controller. The temperature signal can be understood as the temperature signal collected by the temperature sensor set in the virtual simulation device.

[0055] Specifically, the seat heating control system test platform and the virtual simulation device can communicate based on a pre - set wireless communication module, or can also be connected through a bus. When connected through a bus, data is transmitted between the seat heating control system test platform and the virtual simulation device based on the pre - set bus. The seat heating control system test platform heats the vehicle seat system according to the simulation signal sent by the virtual simulation device and obtains the heating control signal and temperature signal of the seat system collected by the virtual simulation device based on the pre - set communication method.

[0056] On the basis of the above technical solution, the seat heating control system test platform includes a seat heating controller, a seat system, a temperature acquisition system, and a thermal imaging system; wherein, the seat heating controller is used to drive the seat system based on the simulation signal so that the seat system is heated; the seat system is used to heat the seat cushion and backrest of the seat based on the working signal of the seat heating controller; the temperature acquisition system is used to acquire the seat surface temperature and the backrest temperature of the seat system; the thermal imaging system is deployed on the surface of the seat and is used to acquire the thermal imaging data of the seat.

[0057] Specifically, the seat heating controller in the seat heating control system test platform drives the seat system according to the received simulation signal, thereby enabling the seat system to produce a corresponding heating effect. For example, if the current simulation signal corresponds to the comfort mode, the seat system is driven to heat to the most suitable temperature range for the human body according to the current simulation signal. The seat system heats the seat cushion and backrest of the seat according to the signal sent by the seat heating controller. It can be understood that existing seat systems often set electric heaters at corresponding positions on the seat, and the seat can be heated through the electric heaters. The temperature acquisition system can acquire the temperatures of the seat surface and the backrest through preset temperature sensors. The thermal imaging system pre-set on the seat surface can acquire the thermal imaging data of the seat.

[0058] The upper computer subsystem communicates with the seat heating control system test platform and is used to receive the heating control signal and the temperature signal, and generate a test report based on the heating control signal and the temperature signal.

[0059] Among them, the test report can be evaluation information for the functions and performance of the seat heating control system.

[0060] Specifically, after the seat heating control system test platform completes the simulation of the seat heating control system under the selected working conditions according to the simulation signal generated by the virtual simulation device, the collected information is transmitted to the upper computer subsystem through a preset information transmission method, and the upper computer subsystem generates a test report based on the collected heating control signal and temperature signal.

[0061] On the basis of the above technical solution, in the upper computer subsystem, there is also included: a test report generation module, which is used to receive the heating control signal and the temperature signal, compare and process them with the collected true values, determine the performance of the seat heating system, and generate a test report corresponding to the performance.

[0062] Among them, the true value can be the true temperature signal collected by the sensors set on the seat heating control system test platform.

[0063] Specifically, the test report generation module in the upper computer subsystem receives the heating control signal and the temperature signal sent by the seat heating control system test platform, compares the received heating control signal and the temperature signal with the actual collected real temperature information, determines the performance of the seat heating system according to the comparison result, and generates a test report corresponding to the performance. For example, the selected test condition is the working mode under extremely cold conditions. Assume that the final heating temperature of the seat heating control system under extremely cold conditions during design is A. After simulating the working condition of the seat heating control system under extremely cold conditions according to the preset method, the real temperature under the current condition collected is B. If B≥A, it proves that the performance of the current seat heating control system meets the design requirements; if B<A, it proves that the performance of the current seat heating control system does not meet the design requirements.

[0064] In the technical solution of the embodiment of the present disclosure, by inputting various working parameters into the upper computer subsystem, the upper computer subsystem generates a corresponding test sequence according to the input parameters, and the virtual simulation device generates a corresponding simulation signal according to the test sequence, and sends the simulation signal to the seat heating control system test platform. The seat heating control system test platform controls the heating of the seat system according to the simulation signal, obtains the heating control signal and the temperature signal of the seat system based on the virtual simulation device, and transmits them to the upper computer subsystem. The upper computer subsystem generates a test report based on the heating control signal and the temperature signal, realizing the automated test of the seat heating control system, saving human resources, and improving the test efficiency.

Among them, the power control model is used to provide various voltage and current power input conditions to the seat heating controller; the seat temperature sensor simulation model is used to simulate the resistance values of the seat temperature sensor in different scenarios, calculate the resistance values of the seat temperature sensor at different temperatures through calibration data, so as to simulate the change of the resistance value of the seat temperature sensor under actual working conditions, such as low-temperature heating, normal-temperature heating, temperature signal hysteresis interval fluctuation and other working conditions, and cooperate with the automated test sequence to complete the simulation of the resistance values of the seat temperature sensor in multiple scenarios; the seat heating output acquisition model is used to collect the heating output control signal of the seat heating controller, and can collect the duty cycle and frequency in real time, which is convenient for analyzing the correctness of the control strategy; the seat temperature acquisition model is used to collect the surface temperature of the seat, and can collect the surface temperature when there are passengers and no passengers on the seat; the thermal imaging acquisition model is used to collect the surface temperature of the seat when there are no passengers and the heating uniformity effect of the seat surface after being heated; the CAN network model is used to simulate the network environment around the seat heating controller.

The thermal imaging system can collect the seat surface temperature in real time during the heating process.

[0072] Figure 5 FIG. is a schematic structural diagram of the seat heating system test platform provided in the second embodiment of the present disclosure, as Figure 5 shown. The seat heating control system test platform includes: a seat heating control, a seat system, a temperature acquisition system, and a thermal imaging system. The seat heating controller is used to drive the seat system, and at the same time, the heating signal is collected by the virtual simulation device to calculate the duty cycle and frequency of the control signal in real time; the seat system is used to heat the seat cushion and backrest, and is the driving load of the seat heating controller; the temperature acquisition system is used to collect the temperature of the seat surface, and the temperature patch resistors are installed at different positions on the seat surface to monitor the seat surface temperature with and without passengers in real time; the thermal imaging system is used to collect the temperature of the seat surface, and the thermal imaging device is placed above the seat surface, and the thermal imaging data is transmitted to the virtual simulation device in real time. The seat heating control, the seat system, and the temperature acquisition system are connected through hard wires and the IO board and the CAN board.

[0073] Specifically, the temperature acquisition system uses patch resistors to accurately measure the seat surface temperature with and without passengers, and test the seat heating rate, which is beneficial to improving the repeatability and accuracy of the test process and avoiding accidental errors caused by human perception in the test. The thermal imaging system can collect the seat surface temperature in real time during the heating process and detect whether the heating area is uniform.

[0074] Specifically, the host computer system sends control signals to the power control model, seat temperature sensor model, and CAN network model in the real-time processor through the automation database. The power control model supplies power to the seat heating controller and the seat system; the CAN network model simulates the normal working environment of the seat heating controller and sends control instructions for the seat heating controller at the same time. For example, heating at gear 1, heating at gear 2, and heating at gear 3; the seat temperature sensor model simulates the temperature acquisition data of the seat heating controller and provides the ambient temperature for it to implement heating strategies under different working conditions. The real-time processor transmits the calculated signal instructions to the seat heating controller through the IO board and the CAN board.
