The vehicle-mounted host is mainly used for realizing functions of navigation, in-vehicle entertainment control, wireless communication and the like, and is provided with a broadcasting module which is used for realizing a frequency modulation broadcasting function.

In this embodiment of the application, when a test of a frequency modulation broadcast is performed, a test host may be started, the test host may start a test operation on any test frequency within a preset test frequency range, and for a target test frequency within the preset test frequency range, the test host may generate a voice control instruction based on the target test frequency and send the voice control instruction to the vehicle host.

Further, the vehicle-mounted host computer can send the target test frequency to the core test device while sending the voice control instruction, so that the core test device performs frequency conversion according to the target test frequency and then outputs a radio frequency signal matched with the target test frequency to the vehicle-mounted host computer, so that the vehicle-mounted host computer starts the broadcast module through the voice control instruction and searches channels based on the radio frequency signal. After the broadcast module searches the channel, a display screen of the vehicle-mounted host computer displays a channel interface, and the channel interface has the actual frequency of the searched channel. In addition, if the core testing device superimposes the audio signal corresponding to the target testing frequency in the radio frequency signal, after the broadcasting module searches a channel corresponding to the target testing frequency, the broadcasting module can broadcast the broadcasting voice aiming at the target testing frequency in the channel, if the broadcasting content is 'currently XX frequency', the screenshot of the broadcasting voice and the channel interface can be used as the relevant information of the channel searched by the broadcasting module, one or more information in the screenshot of the broadcasting voice and the channel interface can be acquired by the testing host for the testing host to analyze, so as to obtain the actual frequency of the channel searched by the broadcasting module, and under the condition that the actual frequency is the same as the target testing frequency, the testing of the target testing frequency is determined to be completed, under the condition that the actual frequency is different from the target testing frequency, the testing of the target testing frequency is considered to be failed, there is a disturbance fault to be verified.

In addition, the test host obtains the associated information of the channels searched by the broadcast module to analyze and obtain the actual frequency of the channels searched by the broadcast module, and accurately determines whether the broadcast module searches the channels corresponding to the specified frequency or not by comparing the actual frequency with the target test frequency, so that the test accuracy is improved.
