[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0025] Embodiment 1

[0026] Figure 1 It is a flow chart of a voltage conversion controller test method provided by the first embodiment of the present invention. This embodiment is applicable to the situation of how to test the voltage conversion controller. The method can be executed by a voltage conversion controller test device, which can be implemented by software and / or hardware, and can be integrated into an electronic device that carries the voltage conversion controller test function, such as a real-time simulation system of a server device. Optionally, the real-time simulation system can realize the real-time calculation of the real vehicle model, and can send the corresponding work instructions to the voltage conversion controller through the communication module. At the same time, the real-time simulation system can also simulate other modules of the vehicle (such as loads, etc.) through the signal conditioning box to interact with the voltage conversion controller. Further, the real-time simulation system may include a real-time processor and an FPGA board; the output voltage of the programmable power supply is controlled by a voltage control signal, the voltage and current signals are collected by an IO board and a signal conditioning board, the vehicle model is run by a real-time processor and an FPGA board, and the bus signal (such as fault information) and the electronic load drive signal (such as work instructions) are sent to the voltage conversion controller through the IO board, the signal conditioning board and the fault injection board.

[0027] like Figure 1 As shown, the method may specifically include:

[0028] S110 , controlling the power supply simulation device to provide input power to the voltage conversion controller, and determining an expected working value required by the load simulation device.

[0029] In this embodiment, the power supply simulation device is a device that simulates the actual power supply for the voltage converter, for example, it can be a simulated high voltage and a programmable power supply. The so-called load simulation device refers to a load device that simulates the output voltage of the consumption voltage conversion controller, for example, it can be a simulated electrical device in a vehicle, such as an air conditioner. The so-called expected working value refers to the energy value required for the normal operation of the load simulation device, for example, it can be an expected voltage value, an expected signal instruction, an expected fault information, etc. Among them, the expected signal instruction can be a wake-up instruction, etc., and the expected fault information can be an expected fault code, etc.

[0030] Exemplarily, the real-time simulation system can simulate the high-voltage power supply through the hardware-in-the-loop simulation platform, and then control the high-voltage power supply to provide input power to the voltage conversion controller. Specifically, the real-time simulation system simulates the high-voltage power supply through the hardware-in-the-loop simulation platform, and sends a control instruction to the simulated high-voltage voltage to supply power to the voltage conversion controller, so that the simulated high-voltage power supply delivers power to the voltage conversion controller.

[0031] Exemplarily, the real-time simulation system can simulate the program-controlled power supply through the hardware-in-the-loop simulation platform, and then control the program-controlled power supply to provide input power to the voltage conversion controller. Specifically, the real-time simulation system simulates the program-controlled power supply through the hardware-in-the-loop simulation platform, and sends a control instruction to the simulated program-controlled power supply to supply power to the voltage conversion controller, so that the simulated program-controlled power supply delivers power to the voltage conversion controller.

[0032] Exemplarily, the real-time simulation system can simulate the high-voltage power supply and the program-controlled power supply through a hardware-in-the-loop simulation platform, and then control the high-voltage power supply and the program-controlled power supply to provide input power to the voltage conversion controller.

[0033] Furthermore, the real-time simulation system can also determine the expected working value required by the load simulation device to ensure that the voltage conversion controller can output the electric energy required by the load simulation device.

[0034] S120, sending a working instruction including an expected working value to the voltage conversion controller, so that the voltage conversion controller converts the input electric energy into an actual working value according to the working instruction, and feeds back the actual working value to the real-time simulation system.

[0035] In this embodiment, the actual working value refers to the energy required for the load simulation device to actually work. The so-called working instruction is an instruction for instructing the voltage conversion controller to work, for example, it may include an expected working value and other working instruction signals, such as expected wake-up information.

[0036] Specifically, the real-time simulation system sends a working instruction including an expected working value to the voltage conversion controller. Accordingly, the voltage conversion controller receives the working instruction and converts the input electrical energy into an actual working value according to the working instruction, and then feeds the actual working value back to the real-time simulation system.

[0037] S130: Determine whether the logic function of the voltage conversion controller is normal according to the actual working value and the expected working value.

[0038] In this embodiment, the logic function is a function of a voltage conversion controller, which may include a power supply function and / or a diagnostic storage function; the power supply function includes at least one of an AC / DC conversion function, an AC / DC isolation function, a charging current compensation function, a charging mode, and an AC discharge function. Furthermore, the logic function may also include a wake-up function, a communication control function, and a charging guidance circuit identification function.

[0039] Specifically, the real-time simulation system receives the actual working value fed back by the voltage conversion controller, and then can determine whether the logic function of the voltage conversion controller is normal based on the actual working value and the expected working value based on the statistical analysis algorithm. For example, based on the comparison model, the actual working value and the expected working value can be input into the comparison model, and after model processing, a judgment result of whether the logic function of the voltage conversion controller is working normally can be obtained.

[0040] It should be noted that the actual working value corresponds to the expected working value. If the expected working value is the expected voltage value, the actual working value is the actual voltage value; if the expected working value is the expected fault information, the actual working value is the actual fault information; if the expected working value is the expected signal information (such as expected wake-up information), the actual working value is the actual signal response result (such as actual wake-up information).

[0041] The technical solution of the embodiment of the present invention provides input power to the voltage conversion controller by controlling the power supply simulation device, and determines the expected working value required by the load simulation device, and then sends a work instruction including the expected working value to the voltage conversion controller, so that the voltage conversion controller converts the input power into the actual working value according to the work instruction, and feeds the actual working value back to the real-time simulation system, and then determines whether the logic function of the voltage conversion controller is normal according to the actual working value and the expected working value. The above technical solution speeds up the development progress of the voltage conversion controller, realizes the comprehensive testing of the voltage conversion controller, and provides a new idea for the testing of the voltage conversion controller.

[0042] Embodiment 2

[0043] Figure 2 1 is a flow chart of a voltage conversion controller testing method provided in the second embodiment of the present invention, which is further optimized on the basis of the above embodiment to provide an optional implementation scheme. Figure 2 As shown, the method may specifically include:

[0044] S210, controlling the power supply simulation device to provide input power to the voltage conversion controller, and determining the expected working value required by the load simulation device.

[0045] S220, sending a working instruction including an expected working value to the voltage conversion controller, so that the voltage conversion controller converts the input electric energy into an actual working value according to the working instruction, and feeds back the actual working value to the real-time simulation system.

[0046] In an optional manner, if the expected working value is the expected voltage value, a working instruction including the expected voltage value is sent to the voltage conversion controller, so that the voltage conversion controller converts the input electrical energy into the actual voltage value according to the working instruction, and feeds the actual voltage value back to the real-time simulation system. Specifically, the real-time simulation system sends the working instruction including the expected voltage value to the voltage conversion controller; accordingly, the voltage conversion controller receives the working instruction, and converts the input electrical energy into the actual voltage value according to the working instruction, and feeds the actual voltage value back to the real-time simulation system.

[0047] Another optional method is that if the expected working value is the expected fault information, the real-time simulation system simulates the expected fault information interacting between other modules in the vehicle system and the voltage conversion controller; a working instruction including the expected fault information is sent to the voltage conversion controller, so that the voltage conversion controller records the actual fault information according to the working instruction, and feeds back the actual fault information to the real-time simulation system. Specifically, the real-time simulation system sends the working instruction including the expected fault information to the voltage conversion controller, which can also be understood as the real-time simulation system sending the expected fault information to the voltage conversion controller through the fault injection card; accordingly, the voltage conversion controller receives the working instruction, records the actual fault information, and feeds back the actual fault information to the real-time simulation system.

[0048] In another optional manner, if the expected working value is the expected wake-up information, the real-time simulation system sends a working instruction including the expected wake-up information to the voltage conversion controller; accordingly, the voltage conversion controller responds to the working instruction, wakes up the voltage conversion controller, and feeds back the actual wake-up information to the real-time simulation system.

[0049] It should be noted that the real-time simulation system can also simulate other information that interacts with the voltage conversion controller, so that the voltage conversion controller performs corresponding work and feeds back corresponding actual signals, which will not be elaborated in detail here.

[0050] S230: Determine whether the logic function of the voltage conversion controller is normal according to the actual working value and the expected working value.

[0051] An optional way, if the actual working value is the actual voltage value, then according to the actual working value and the expected working value, determining whether the logic function of the voltage conversion controller is normal can be, if the actual voltage value is consistent with the expected voltage value, then determining that the power supply function of the voltage conversion controller is normal. Specifically, based on the comparison model, the actual voltage value and the expected voltage value can be input into the comparison model to output whether the power supply function of the voltage conversion controller is normal. Furthermore, the actual voltage value and the expected voltage value can be subtracted, and if the result after the subtraction is less than within the set range, it is determined that the power supply function of the voltage conversion controller is normal. Among them, the setting range can be set by a technician in this field according to actual conditions.

[0052] Another optional method is that if the actual working value is the actual fault information, then according to the actual working value and the expected working value, determining whether the logic function of the voltage conversion controller is normal can be that if the actual fault information is consistent with the expected fault information, then determining whether the diagnostic storage function of the voltage conversion controller is normal. Specifically, based on the comparison model, the actual fault information and the expected fault information can be input into the comparison model to output whether the diagnostic storage function of the voltage conversion controller is normal. Among them, the actual fault information can be a fault code.

[0053] Another optional method is that if the actual working value is the actual wake-up information, then determining whether the logic function of the voltage conversion controller is normal based on the actual working value and the expected working value can be that if the actual wake-up information is consistent with the expected wake-up information, it is determined that the wake-up function of the voltage conversion controller is normal.

[0054] The technical solution of the embodiment of the present invention provides input power to the voltage conversion controller by controlling the power supply simulation device, and determines the expected working value required by the load simulation device, and then sends a work instruction including the expected working value to the voltage conversion controller, so that the voltage conversion controller converts the input power into the actual working value according to the work instruction, and feeds the actual working value back to the real-time simulation system, and then determines whether the logic function of the voltage conversion controller is normal according to the actual working value and the expected working value. The above technical solution speeds up the development progress of the voltage conversion controller, realizes the comprehensive testing of the voltage conversion controller, and provides a new idea for the testing of the voltage conversion controller.
