Abstract

The invention discloses a control method of an alarm sounding device based on an automobile sound system. The alarm sounding device based on the automobile sound system comprises a body control module, the automobile sound system and a controller area network bus which is connected with the body control module and the automobile sound system. The body control module sends an alarm signal to a host of the automobile sound system in the form of a message through the controller area network bus. When the host of the automobile sound system is in a dormant state, a standby state or a working state, an alarm reminding sound is sent through the control method; the alarm reminding sound sent from sound equipment is improved in sound quality; besides, a buzzer is omitted and thus the cost of the whole vehicle is reduced.

Description

technical field [0001] The invention relates to a control method of an automobile safety device, in particular to a control method of an alarm sounding device of an automobile audio system. Background technique [0002] Existing automobile alarm sounding devices all adopt buzzers, and when there is an alarm task operation to perform, the driver is prompted by the sound sent by the buzzer. The warning tone of buzzer is single, can not satisfy the driver's requirement to the sound quality of warning tone. In addition, the buzzer added to the car also increases the cost of the car. Therefore existing automobile alarm sounding device needs to carry out certain improvement. Contents of the invention [0003] The object of the present invention is to provide a control method of an alarm sounding device based on a car audio system, which can not only improve the sound quality of the alarm sound, but also reduce the cost of the car. [0004] The control method of the alarm soun...
