The system can realize the opening and closing control of the electric door by a user in a non-contact mode outside the vehicle.
In the present embodiment, the electric door will be described as an example of an electric tailgate.
As shown in fig. 1, the contactless control system for the power tailgate in the present embodiment includes: the system comprises an external audio processing module 12, a tail gate control module 13, an online identification processing module 14 and a whole vehicle awakening module 15. The external audio processing module 12 comprises an external microphone 1 and an external voice recognizer 2 connected with the external microphone, and the tail gate control module 13 comprises: the central control processor 3, the CAN network 9, the BDCR controller 6 as a door controller and the door electric stay 7 of a door actuating mechanism, wherein the BDCR controller 6 is connected with the central control processor 3 through the CAN network 9; the whole vehicle awakening module 14 includes: a key 4 and a BCM body controller 5; the online identification processing module 14 includes: an in-vehicle microphone 11, an in-vehicle speech recognizer 8 and a cloud recognition system 10.
Wherein: the exterior microphone 1 and the exterior speech recognizer 2 constitute an exterior audio processing module 12. The external microphone 1 is responsible for picking up all sound signals outside the vehicle, the external voice recognizer 2 carries out noise elimination (noise reduction) and gain adjustment on all external sound signals (namely external audio) picked up by the external microphone 1, the external sound signals after being processed and a tail gate wake-free word model in the external audio processing module 12 are compared to generate a corresponding electric tail gate control instruction (the instruction is a serial port instruction) and are sent to the tail gate control module 13, and meanwhile, the external sound signals after being noise reduced are converted into audio analog signals and are sent to the tail gate control module 13.
Wherein: the in-vehicle speech recognizer 8, the cloud recognition system 10 and the in-vehicle microphone 11 form an online recognition processing module 14. The in-vehicle speech recognizer 8 is responsible for receiving the audio analog signal transmitted to the tailgate control module 13 by the out-vehicle audio processing module 12. By means of the storage capacity of the cloud identification system 10 with strong high-speed computing capability, the online identification processing module 14 can process many audio frequencies which cannot be identified by the off-board audio processing module 12, and finally the audio frequencies are processed and corresponding tailgate control instructions are generated and sent to the tailgate control module 13. Meanwhile, the in-vehicle speech recognizer 8 is also responsible for processing the out-vehicle audio signals picked up by the in-vehicle microphone, performing noise elimination (noise reduction) and gain adjustment on the out-vehicle audio signals, recognizing the processed out-vehicle audio signals by using a locally stored in-vehicle tail gate control word model, generating corresponding tail gate control commands and sending the tail gate control commands to the tail gate control module 13.
The central control processor 3, the BDCR controller 6, the CAN network 9, and the tail gate electric stay constitute a tail gate control module 13 in this embodiment, as shown in fig. 2, the tail gate control module 13 is responsible for providing an operating power supply for the vehicle exterior audio processing module 12 and the online identification processing module 14, and is also responsible for converting the vehicle exterior audio digital signal processed by the vehicle exterior audio processing module 12 into a vehicle exterior audio analog signal and transmitting the vehicle exterior audio analog signal to the online identification processing module 14. The tail gate control module 13 is an actual execution layer of the whole system, and the last opening and closing process of the tail gate is executed by the tail gate control module 13.
As shown in fig. 1, the key 4 and the BCM body controller 5 form a whole vehicle wake-up module 15, which is responsible for waking up a whole vehicle at the first time when a user approaches the vehicle, and simultaneously notifying the tailgate control module 13 to enter a working state, so that the user can perform voice control on the tailgate at the first time when the user approaches the vehicle.
In order to implement the contactless control of the power tailgate, as shown in fig. 9, the contactless control method of the power tailgate in this embodiment specifically includes:
and S101, sleeping and awakening the whole vehicle.
In the embodiment, a wake-up mode for sleep wake-up of a whole vehicle is provided.
Specifically, in order to ensure that the dark current of the automobile meets the requirement and reduce the feeding risk of the automobile, the external voice recognizer 2 and the central control processor 3 can be deeply dormant under the condition that the power of the whole automobile is not used, but simultaneously, a low-frequency antenna module in the BCM automobile body controller 5 is still in a working state, and when the key 4 receives a low-frequency antenna signal, a high-frequency signal with self ID authentication is sent to the BCM automobile body controller 5 at the end of the automobile. If the BCM automobile body controller 5 receives the high-frequency signal as the (2), the BCM automobile body controller 5 can carry out the legal verification of the ID in the high-frequency signal;
if the ID check is illegal, the BCM vehicle body controller 5 cannot wake up the whole vehicle;
if the ID is verified to be legal, the BCM vehicle body controller 5 issues a wake-up command to the whole vehicle, and simultaneously, the central control processor 3 is awakened from dormancy.
After the central control processor 3 is awakened, power supply and a clock are provided for the exterior voice recognizer 2, and power supply is provided for the exterior microphone 1, so that the exterior voice recognizer 2 can carry out local recognition.
And S102, picking up the out-of-vehicle audio of the out-of-vehicle user.
For example, a user outside the vehicle can directly say that the wake-up free word of "xx opens the back door" directly controls the opening of the back door; or the external voice recognizer 2 enters the recognition mode by saying 'hello xx' first, and then the tail gate is controlled to be opened by saying command words such as 'please help me open the tail gate', 'open the tail gate', and the like.
In this embodiment, the off-vehicle audio acquisition of the off-vehicle user can be picked up by an off-vehicle microphone 1 arranged outside the vehicle; it is also possible to perform pickup by the in-vehicle microphone 11 disposed in the vehicle when the vehicle tail gate is opened.
Step S103, the outside-vehicle voice recognizer 2 performs awakening word matching or awakening-free word matching on the outside-vehicle audio picked up by the outside-vehicle microphone 1, and judges whether the tail gate control instruction is directly output or the outside-vehicle audio picked up by the outside-vehicle microphone 1 again needs to be recognized after entering the recognition mode so as to output the tail gate control instruction.
The external speech recognizer 2 locally stores four models, specifically: a tail gate wake-free word model, a recognition mode wake-up word model, a recognition mode voiceprint model and a local tail gate control word model.
Wherein, the record has exempted from to awaken up the word in the word model is exempted from to the tail-gate, in case the car outer user directly says and should exempt from to awaken up the word, the car outer speech recognizer 1 can direct output tail-gate control command.
The recognition mode awakening word model records some awakening words for the off-board speech recognizer 2 to enter the recognition mode, the awakening words are pre-stored in the recognition mode awakening word model, and once the off-board user speaks one or more of the awakening words, the off-board speech recognizer 1 can enter the recognition mode or be qualified to enter the recognition mode.
Voiceprint data are not stored in the voiceprint model in the recognition mode in advance, and the voiceprint data need to be actively registered and input by a user. Once the user registers the voiceprint data, the voiceprint data is recorded in the voiceprint model in the recognition mode, namely the voiceprint recognition mode of the vehicle-mounted voice recognizer 2 in the embodiment is started; and when the voiceprint data is not recorded in the recognition mode voiceprint model, the voiceprint recognition mode of the vehicle exterior voice recognizer 2 is closed. When the user starts voiceprint recording by clicking the interface, the central control processor 3 informs the vehicle-exterior voice recognizer 2 to carry out an audio recording mode at the moment, and simultaneously, information for guiding the user to record outside the vehicle is displayed on the interface of the central control processor 3. At this moment, the outer microphone 1 of the vehicle transmits the outer audio frequency of the vehicle to the outer voice recognizer 2 in real time, when the outer audio frequency of the hit awakening word 'hello XX' is recognized, the audio frequency is stored in a voiceprint model of the outer voice recognizer 2 of the vehicle until 5 pieces of awakening audio frequency are continuously stored, and the recording of the hypo-cartilages can be finished.
After the vehicle exterior voice recognizer 2 enters the recognition mode, once one or more control words matched with the control words are recorded in the vehicle exterior audio spoken by the vehicle exterior user again, a tail door control command for opening and closing the tail door can be output.
For the vehicle exterior speech recognizer 2, when the voiceprint recognition mode is closed, if the user has spoken one or more awakening words in the model according to the recognition mode awakening word model, the vehicle exterior speech recognizer 2 directly enters the recognition mode; when the voiceprint recognition mode is started, when one or more awakening words in the recognition mode awakening word model are matched in the vehicle exterior audio, the voiceprint data of the vehicle exterior audio is required to be matched with one piece of voiceprint data in the recognition mode voiceprint model, and then the vehicle exterior voice recognizer 2 can enter the recognition mode.
When the external audio is picked up by the external microphone 1, the external voice recognizer 2 firstly receives the external audio, and firstly carries out noise elimination and gain adjustment on the received external audio and then analyzes the external audio into a digital signal.
With reference to the first path in fig. 3, 4 to 7, the off-board speech recognizer 1 inputs the analyzed off-board audio digital signal into the local wake-up-free word model of the end gate, and the wake-up-free word model of the end gate matches whether the wake-up-free word "xx opens the end gate" or "xx closes the end gate" is recorded in the off-board audio, and if the wake-up-free word is recorded in the off-board audio, the off-board speech recognizer 2 directly outputs a first end gate control instruction for opening or closing the end gate to the central processing unit 3.
As shown in fig. 3, the vehicle exterior speech recognizer 1 needs to select whether to input the analyzed vehicle exterior audio digital signal only to the above recognition mode wakeup word model or to input the processed vehicle exterior audio to both the above recognition mode wakeup word model and the above recognition mode voiceprint model according to whether the voiceprint recognition mode is on while inputting the analyzed vehicle exterior audio digital signal to the local backdoor wakeup word model. Specifically, when the voiceprint recognition mode is turned on, the processed vehicle exterior audio needs to be simultaneously input into the recognition mode wake-up word model and the recognition mode voiceprint model, which corresponds to fig. 4 and 6; when the voiceprint recognition mode is turned on, the processed vehicle exterior audio needs to be input into only the recognition mode wake-up word model described above, which corresponds to fig. 5 and 7.
For the above-mentioned vehicle exterior speech recognizer 2, if it needs to enter the recognition mode first and then recognize the vehicle exterior audio picked up by the vehicle exterior microphone 1 again to output the tail gate control command, at this time, the output tail gate control command may be one of the second tail gate control command to the fifth tail gate control command in fig. 4 to fig. 7.
And step S104, if the step S103 judges that the command is directly output, the exterior voice recognizer 2 directly outputs a first tail gate control command to the central control processor 3, so that the central control processor 3 realizes the tail gate opening and closing control according to the first tail gate control command.
As shown in fig. 3 to fig. 7, the step S104 corresponds to a first path, which enables the issue and execution of the tail gate control command to be performed quickly and conveniently.
If it is determined in step S103 that it is necessary to enter the recognition mode first and then recognize the vehicle exterior audio picked up by the vehicle exterior microphone 1 again to output the tailgate control command, there are two paths from step S105 to step S106.
In step S105, the out-vehicle speech recognizer 2 outputs a second tailgate control instruction.
The step S105 corresponds to the second path in fig. 4, and the specific steps of the step S105 are:
if the voiceprint recognition mode is started, outputting a request for inputting feedback information containing control words by a user outside the vehicle;
when the off-vehicle audio which is picked up by the off-vehicle microphone 1 and input again by the off-vehicle user based on the feedback information is acquired, inputting the picked off-vehicle audio into the local tail gate control word model for matching;
and if the control words in the local tail gate control word model can be matched from the picked-up vehicle exterior audio, outputting the second tail gate control command.
When the voiceprint recognition mode is started, the second path can effectively guarantee the use safety of the user, and meanwhile, the local low transmission path is utilized, and the external audio of the user can be fed back quickly.
In step S106, the out-of-vehicle speech recognizer 2 outputs a third tailgate control instruction.
The step S106 corresponds to the third route in fig. 5, and the specific steps of the step S106 are as follows:
if the voiceprint recognition mode is not started, outputting a request for inputting feedback information containing control words by a user outside the vehicle;
when the vehicle exterior audio which is picked up by the vehicle exterior microphone 1 and input again by the vehicle exterior user based on the feedback information is obtained, inputting the vehicle exterior audio which is picked up again into the local tail gate control word model for matching;
and if the control words in the local tail gate control word model can be matched from the picked-up vehicle exterior audio, outputting the third tail gate control command.
The execution process of the step S105 is the same as that of the step S106, and the difference is that the precondition of the step S105 is that the vehicle exterior speech recognizer 2 enters the recognition mode after the recognition mode wakeup word model and the recognition mode voiceprint model are matched together; the precondition of step S106 is that the off-board speech recognizer 2 can enter the recognition mode by separately matching the recognition mode wakeup word model.
Compared with the step S105, the third path has less voiceprint matching time and recognition mode voiceprint model matching time, so that the wakeup rate and the response speed of the vehicle-external speech recognizer 2 are faster, and the local low transmission path is utilized to perform fast feedback on the instruction of the user, and the response speed of the third path is a fastest response path except for the wakeup-free instruction.
When the local tail gate control word model of the vehicle exterior voice recognizer 2 is used for matching control words, the vehicle exterior voice recognizer 2 converts the vehicle exterior audio frequency which is picked up again into a digital signal from an analog signal and then sends the digital signal to the central control processor 3; the central processor 3 converts the external audio digital signals into analog signals again, and outputs the external audio analog signals to the cloud recognition system 10 through the in-vehicle voice recognizer 8.
In step S107, the in-vehicle speech recognizer 8 outputs a fourth tailgate control instruction.
The step S107 corresponds to the path four in fig. 6, and the specific steps of the step S107 are:
if the voiceprint recognition mode is started, outputting a request for inputting feedback information containing control words by a user outside the vehicle;
when the off-vehicle audio which is picked up by the off-vehicle microphone 1 and input again by the off-vehicle user based on the feedback information is acquired, inputting the picked off-vehicle audio into the local tail gate control word model for matching;
if the control words in the local tail gate control word model cannot be matched from the picked-up outside audio, the picked-up outside audio is transferred to the cloud recognition system 10 through the central control processor 3 and the in-vehicle voice recognizer 8, and the online tail gate control word model of the cloud recognition system 10 is used for matching the control words;
if the control words in the local tail gate control word model can be matched from the picked-up external audio, the cloud recognition system 10 outputs the fourth tail gate control command, and the in-vehicle voice recognizer 8 sends the fourth tail gate control command to the central control processor 3.
For the cloud recognition system 10, the online tail gate control word model records some control words with more control words and richer vocabularies than those in the local tail gate control word model. Since the cloud recognition system 10 stores a huge amount of recognition resources, the cloud recognition system 10 can recognize many control word resources that are not stored in the off-vehicle speech recognizer 2, and therefore the cloud recognition system 10 can recognize more user commands.
The safety of the user can be effectively guaranteed under the fourth path, and all instructions of the user can be recognized by utilizing the high semantic generalization capability of the cloud.
In step S108, the in-vehicle speech recognizer 8 outputs a fifth tailgate control instruction.
The step S108 corresponds to the path five in fig. 7, and the specific steps of the step S108 are:
if the voiceprint recognition mode is not started, outputting a request for inputting feedback information containing control words by a user outside the vehicle;
when the vehicle exterior audio which is picked up by the vehicle exterior microphone 1 and input again by the vehicle exterior user based on the feedback information is obtained, inputting the vehicle exterior audio which is picked up again into the local tail gate control word model for matching;
if the control words in the local tail gate control word model cannot be matched from the picked-up external audio, the picked-up external audio is transferred to the cloud recognition system 10 through the central control processor 3 and the in-vehicle voice recognizer 8, and the online tail gate control word model of the cloud recognition system 10 is used for matching the control words;
if the control words in the local tail gate control word model can be matched from the picked-up external audio, the cloud recognition system 10 outputs the fourth tail gate control command, and the in-vehicle voice recognizer 8 sends the fourth tail gate control command to the central control processor 3.
For the cloud recognition system 10, the online tail gate control word model records some control words with more control words and richer vocabularies than those in the local tail gate control word model. Since the cloud recognition system 10 stores a huge amount of recognition resources, the cloud recognition system 10 can recognize many control word resources that are not stored in the off-board speech recognizer 2, so that the cloud recognition system 10 can recognize more user commands, and can recognize more user commands compared to the above steps S105 and S106.
Meanwhile, compared with the step S107, in the step S108, the matching time of the voiceprint matching and the matching time of the recognition mode voiceprint model are reduced in the path five, so that the wakeup rate and the response speed of the speech recognizer 2 outside the vehicle are quicker, and meanwhile, the instruction of the user can be fed back quickly by using a local low transmission path.
Step S109, the in-vehicle speech recognizer 8 performs control word matching on the outside audio picked up by the outside microphone 1, and outputs a sixth tailgate control instruction.
This step S109 corresponds to the sixth route in fig. 7. The sixth path has a certain opening condition (i.e. on the premise that the tail gate is opened), and mainly plays a role in assisting the wake-up rate.
In order to ensure the success rate of identifying the tail gate control command when the tail gate is opened, when the BDCR controller 6 detects that the state of the tail gate electric stay 7 is an open state (i.e., the tail gate is open), the BDCR controller will inform the central control processor 3 through the CAN network 9, and when the central control processor 3 receives the open state of the tail gate, the BDCR controller identifies the open mode in the vehicle. When the BDCR controller 6 detects that the state of the tail gate electric stay 7 is the non-open state, it will inform the central control processor 3 through the CAN network 9, and when the central control processor 3 receives the non-open state, it will identify the close mode in the vehicle.
Under the condition that the in-vehicle recognition opening mode is opened, if the out-vehicle audio transmitted by the out-vehicle sound source through the in-vehicle microphone 11 hits the on-line tailgate control word model in the in-vehicle voice recognizer 8, the sixth tailgate control instruction is output, and the central control processor 3 judges whether to issue the sixth tailgate control instruction to the BDRC controller 6 through the tailgate opening, the learning state and the running state acquired in real time by the CAN network 9.
The online tailgate control word model in the in-vehicle speech recognizer 8 is masked in the in-vehicle recognition closed mode, and at this time, the tailgate control command in the in-vehicle speech recognizer 8 no longer responds.
In step S110, the central control processor 3 executes the tail gate control instruction.
For the central control processor 3, after receiving the first to sixth tailgate control instructions, the central control processor 3 issues a corresponding tailgate control signal to the CAN network 9, and at this time, when the BDCR controller 6 receives the signal, the BDCR controller directly controls the operation of the tailgate electric stay 7 through the hall signal, thereby finally achieving the purpose of controlling the tailgate.
The embodiment of the invention provides various specific application scenes for realizing the opening and closing control of the vehicle tail gate in a non-contact manner, and realizes the control of the vehicle tail gate by using the voice data outside the vehicle. The voice data outside the vehicle is accurately recognized by combining various recognition modes of voiceprint recognition, awakening-free word recognition and control word recognition, and the accuracy of controlling the tail gate of the vehicle is improved.

the vehicle exterior voice recognizer 2 outputs an electric door control command or judges whether to enter a recognition mode according to the vehicle exterior audio picked by the vehicle exterior microphone 1;
when the vehicle-exterior voice recognizer 2 enters a recognition mode, the central control processor 3 sends vehicle-exterior audio sent by the vehicle-exterior voice recognizer 2 to a cloud recognition system 10 which is connected with the vehicle-interior voice recognizer in advance through the vehicle-interior voice recognizer 8, so that the cloud recognition system 10 performs online model matching to output an electric door control instruction, and the electric door control instruction is sent to the central control processor 3 through the vehicle-interior voice recognizer 2;
