Moreover, the voice voiceprint recognition system carries out voiceprint recognition and pairing on the instruction sent by the user, recognizes and confirms the identity of the user, can ensure that the user is a vehicle owner or a person authorized by the vehicle owner, and can effectively ensure the use safety of the vehicle.
The embodiment also discloses an automobile which adopts the control method of the vehicle action.

Claims (10)
1. A control method for vehicle action is characterized in that a vehicle is in an idling or power-on state, and a voice voiceprint recognition system and an off-vehicle pickup system are in a ready state, and comprises the following steps:
s1, the pickup system outside the vehicle receives the voice signal and transmits the voice signal to the voice print recognition system;
s2, performing semantic recognition on the voice signal by the voice voiceprint recognition system;
s3, judging whether the voice signal is a control command voice signal, if so, executing the step S4;
s4, voiceprint matching, wherein the voiceprint recognition system performs voiceprint feature extraction on the control command voice signal and compares the voiceprint feature extraction with a target voiceprint model stored in a voiceprint library in advance to perform voiceprint matching;
and S5, successfully matching the voiceprint, and executing the execution action contained in the control command voice signal by the vehicle.
2. The vehicle behavior control method according to claim 1, further comprising, before step S3, the steps of: s21, judging whether the voice signal is a wakeup word sound signal; if the voice signal is not the wakeup word tone signal, performing step S3, and if the voice signal is the wakeup word tone signal, performing step S22;
and S22, the vehicle executes a response action of waking up.
3. The vehicle behavior control method according to claim 1, further comprising, before step S3, the steps of: s21, judging whether the voice signal is a word sound awakening signal, if not, performing the step S3; if the voice signal is a wake-up word tone signal, performing step S22;
s22, the voice voiceprint recognition system extracts voiceprint features of the awakening word voice signals and compares the voiceprint features with target voiceprint models stored in a voiceprint library in advance to carry out voiceprint matching;
and S23, if the voiceprint pairing is successful, the vehicle executes a response action of awakening.
4. The method according to claim 1, wherein in step S5, after the voiceprint pairing is successful, and before the vehicle executes the execution action included in the control command voice signal, the short-range pairing of the vehicle key and the vehicle is performed to confirm the identity of the user.
5. The method of claim 1, wherein a short-range pairing of the vehicle key and the vehicle is performed to confirm the identity of the user before step S1.
6. The vehicle motion control method according to claim 1, wherein the voice voiceprint recognition system performs a background noise reduction process or a voice signal-to-noise ratio enhancement process on the voice signal before performing step S2; or
The pickup system outside the vehicle is right to carry out background sound noise reduction processing or speech signal-to-noise ratio enhancement processing on the speech signal.
7. The method according to claim 4 or 5, wherein the vehicle key and the vehicle perform information transmission by short-range radio frequency.
8. The method according to claim 2 or 3, wherein the wake-up response is a turn-on of a tail light, a high mounted stop light, or an out-of-vehicle courtesy light of the vehicle.
9. The vehicle motion control method according to claim 1, wherein the control command voice signal includes an execution motion including: the method comprises the steps of opening a window, closing the window, opening a skylight, closing the skylight, opening a door, closing the door, opening a trunk, closing the trunk, shutting down an engine or powering off the vehicle, and locking the vehicle.
10. An automobile, characterized in that it employs the control method of vehicle behavior according to any one of claims 1 to 9.
