Abstract

The invention discloses an automobile tailgate sound control circuit, comprising: a sound input module, an audio filter module, a voice processing and recognition module, an MCU control module, a tailgate state detection circuit module and a tailgate switch control module; a sound input module, an audio The filtering module, the voice processing and recognition module, and the MCU control module are electrically connected in sequence; the MCU control module is electrically connected with the tailgate state detection circuit module and the tailgate switch control module respectively; the invention also discloses an automobile tailgate sound control circuit The control method includes: inputting voice signals; performing filter processing and digital-to-analog conversion to generate audio data; identifying and analyzing audio data; controlling the opening and closing of the tailgate according to the voice commands to be processed and the switch information of the tailgate. The invention directly opens or closes the electric tailgate of the automobile through the voice command, thereby improving the reliability and safety of the voice control of the tailgate.

Description

technical field [0001] The invention relates to the technical field of automobile electronics, in particular to an automobile tailgate voice control circuit and a control method thereof. Background technique [0002] With the popularity of SUVs, the body of SUVs is relatively high, and the tailgate opens directly upwards. After opening, some of them are more than 1.8 meters in height. Shorter or female car owners may not be able to reach the tailgate switch with their hands raised. In some cases, some people often have to jump up to press the door-closing switch, which is laborious and unsafe. Especially if you have something on hand, it will be even more troublesome to open and close the door. [0003] The patent application text with the patent number 201510133382.X discloses a voice control method for automobile doors and windows, including: a standby step, including: the Bluetooth unit matches the received Bluetooth signal, and if the matching is successful, the Bluetoo...
