Abstract

The invention discloses an automobile tail door voice control circuit. The automobile tail door voice control circuit comprises a voice type-in module, an audio filtering module, a voice processing and recognizing module, an MCU control module, a tail door state detection circuit module and a tail door opening and closing control module, wherein the voice type-in module, the audio filtering module, the voice processing and recognizing module and the MCU control module are electrically connected in sequence; and the MCU control module is electrically connected with the tail door state detectioncircuit module and the tail door opening and closing control module. The invention further discloses a control method for the automobile tail door voice control circuit. The control method comprisesthe following steps: typing in voice signals; carrying out filtering processing and digital-to-analogue conversion so that audio data is generated; carrying out recognition and analysis on the audio data; and controlling the opening and closing of a tail door according to a voice instruction needing to be processed and the opening and closing information of the tail door. The electric tail door ofthe automobile is directly opened or closed through the voice command, and thus the reliability and safety for voice control of the automobile tail door are improved.

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...
