[0052] Example 1

[0053] Please see Figure 1 , Figure 1 The flowchart of a method for testing a multi-zone vehicle computer in a vehicle provided in this embodiment is as follows. The method for testing a multi-zone vehicle computer in a vehicle includes:

[0054] S101. After the vehicle machine to be tested is connected to the necessary components of the vehicle, it is detected whether the voice function of the vehicle machine to be tested can work normally. If so, step S102 is executed; if not, the process ends.

[0055] In this embodiment, the necessary components of the vehicle include at least a central control screen, an instrument screen, a power harness, and a vehicle computer power supply.

The system includes a vehicle computer, a vehicle computer power supply and audio-related wiring harness, a vehicle computer microphone or resistor, a sound card, a DC blocking capacitor, and a computer (i.e., a test device) capable of executing Python code. The method can be converted into Python code for execution.

[0067] In this embodiment, the computer serves as the control end for testing the multi-zone function. It can control the computer to play audio files through code, and control the playback volume of the sound card connected to the computer, thereby controlling the sound volume received by each microphone of the vehicle computer, and finally achieving the effect of simulating the multi-zone function.

[0081] A DC blocking capacitor is connected between the car microphone wiring harness and the sound card device. The DC blocking capacitor is used to ensure normal current on the sound card device.

[0082] In this embodiment, the vehicle microphone harness is used as a necessary harness for multi-zone function testing and is used to input audio content to the vehicle.

[0083] In this embodiment, there is power verification logic for the microphone harness in the vehicle computer. To ensure that the microphone harness works normally, the microphone needs to be connected. If interference from ambient sound is to be avoided, the microphone can be replaced with a resistor with the same resistance as the microphone.

[0084] In this embodiment, the DC blocking capacitor is used to prevent the sound card connected to the car microphone harness from being damaged due to excessive load current. It is specifically arranged between the microphone harness and the sound card to ensure normal current on the sound card.

[0085] S203: Determine the sound card device used for the test according to the sound card device identifier.

[0086] In this embodiment, the sound card can be used as a playback device after being connected to the computer.

[0087] In this embodiment, when the computer plays an audio file, the audio signal can be transmitted to the sound card for playback. At the same time, the sound card can also transmit the audio signal to the connected car microphone harness.

[0088] In this embodiment, each sound card has a unique device name, and in a multi-zone test scenario, a corresponding number of sound cards can be connected according to the number of microphones in the actual vehicle.

[0089] S204: Read the audio to be played according to the audio file path.

[0090] S205: Adjust the playback volume of the sound card device according to the volume of the sound card device.

[0096] In this embodiment, the execution subject of the method may also be a smart device such as a smart phone, a tablet computer, etc., which is not limited in this embodiment.

[0097] It can be seen that the implementation of the automobile multi-zone vehicle computer testing method described in this embodiment can complete the test bench environment for the multi-zone function only through the components necessary for the multi-zone function; at the same time, the test bench construction does not need to simulate the actual vehicle environment construction, which greatly reduces the footprint of the test bench; in addition, there is no external sound during the test process, and there is no mutual interference between multiple multi-zone test benches; finally, the vehicle computer microphone does not need to be used during the test process, which can avoid the problem of inaccurate test results caused by environmental noise interference.
