[0038] The present invention discloses an automatic test system for automobile alarm function, including a test module 1, a simulation module 2, a cockpit domain controller 3, a speaker 4 and a recording module 5, wherein the test module 1 adopts a computer to compare the received alarm audio information with the expected alarm audio information, and the expected alarm audio information is determined by the test module 1 through the analog signal output by the simulation module 2.

The present invention performs a systematic test on the alarm function of the automobile, and the test is comprehensive, thereby reducing the failure rate of the automobile.

[0039] The simulation module 2 uses a CAN bus simulator, which is used to send a simulation signal to the cockpit domain controller 3 according to the test information sent by the test module 1. The present invention will send multiple simulation signals to test the alarm priority sorting function of the cockpit domain controller 3 for automobile faults. In an embodiment of the present invention, the simulation signal sent by the test module 1 through the simulation module 2 includes an engine overheating simulation signal, a brake fault simulation signal, and a headlight fault simulation signal, and the alarm function of the automobile is tested through simulation signals of different fault degrees. The present invention simulates fault signals through simulation equipment, reduces the difficulty of testing, and speeds up the development progress of the project.

[0040] The cockpit domain controller 3 is used to receive the analog signal sent by the simulation module 2, determine the fault type of the car according to the analog signal, sort the fault type of the car according to the alarm priority of the fault type, determine the order of sending the alarm information of the car fault type to the speaker 4, and then send the alarm information corresponding to the different car fault types to the speaker 4 in sequence. In the embodiment of the present invention, the cockpit domain controller 3 receives the engine overheating simulation signal, brake failure simulation signal and headlight failure simulation signal sent by the simulation module 2, sorts them according to the alarm priority, and sends the alarm information corresponding to the brake failure, the alarm information corresponding to the engine overheat and the simulation information corresponding to the headlight failure to the speaker 4 in sequence. The model of the cockpit domain controller 3 in the present invention is Visteon SmartCore TM Cockpit domain controller.

[0041] The loudspeaker 4 is used to receive the alarm information sent by the cockpit domain controller 3 and play it to prompt the user. The alarm information in the present invention is audio information in the *.wav format.

[0042] The recording module 5 uses a microphone to receive the alarm audio information emitted by the speaker 4 and transmit the alarm audio information to the testing module 1 .

[0043] The output end of the computer is connected to the input end of the CAN bus simulator, the output end of the CAN bus simulator is connected to the input end of the cockpit domain controller 3, the output end of the cockpit domain controller 3 is connected to the input end of the speaker 4, and the output end of the microphone is connected to the input end of the computer.

[0044] The present invention provides an automatic testing method for automobile alarm function:

[0045] The test module 1 outputs a simulation signal to the cockpit domain controller 3 through the simulation module 2. In an embodiment of the present invention, the test module 1 outputs an engine overheating simulation signal, a brake failure simulation signal and a headlight failure simulation signal to the cockpit domain controller 3 through the simulation module 2.

[0046] The cockpit domain controller 3 sorts the alarm priorities of the analog signals, and outputs the alarm information corresponding to the analog signals to the speaker 4 in order from high to low according to the alarm priorities. Specifically, the cockpit domain controller 3 sorts the alarm priorities of the engine overheating analog signal, the brake failure analog signal and the headlight failure analog signal, and outputs the brake failure alarm information, the engine overheating alarm information and the headlight failure alarm information to the speaker 4 in order, and the speaker 4 sends out the voice information of "brake failure", "engine overheat" and "headlight failure" in order.

[0047] The test module 1 receives the alarm audio information sent by the loudspeaker 4 through the recording module 5, and compares the alarm audio information with the alarm audio information corresponding to the analog signal output by the test module 1 through the simulation module 2 at the beginning, so as to determine whether the alarm function of the car is normal. It should be noted that the computer downloads the car alarm priority file before the test, sorts the alarm priority for the analog signal sent by the simulation module 2, and generates the alarm audio information corresponding to the analog signal sorting. In the embodiment of the present invention, the test module 1 receives the alarm audio information of "brake failure", "engine overheating" and "headlight failure" sent by the loudspeaker 4 through the recording module 5, and compares the alarm audio information of "brake failure", "engine overheating" and "headlight failure" with the alarm audio information generated after sorting the brake failure simulation signal, engine overheating simulation signal and headlight failure simulation signal output by the test module 1 through the simulation module 2 at the beginning of the test, so as to determine that the comparison in the embodiment is consistent, and the alarm function test of the car passes. When the test module 1 receives the alarm audio information sent by the speaker 4 through the recording module 5, the environmental noise in the audio is filtered out. The means for filtering out the environmental noise in the audio can adopt an adaptive filtering method or an online audio processing tool. The present invention filters out the environmental noise from the alarm audio information of the speaker 4 collected by the test module 1, thereby improving the accuracy of the test.
