in step 102, if the voice instruction is judged to be an effective instruction, judging whether voiceprint information of the effective instruction is matched with preset vehicle unlocking voiceprint information;
in step 103, if the voiceprint information of the effective instruction is matched with the preset vehicle unlocking voiceprint information, controlling the vehicle to unlock.
In this embodiment, for step 101, in response to sensing a vehicle unlocking device, the vehicle unlocking device starts a vehicle voice recognition system to detect a voice command of a user, and determines whether the voice command is a valid command, where the vehicle is equipped with the wearable vehicle unlocking device, the vehicle further includes the vehicle voice recognition system and preset vehicle unlocking voiceprint information, for example, the vehicle sensing device is a vehicle key, when a user carrying the key approaches the vehicle, the vehicle unlocking device first senses the key, and then starts the vehicle voice recognition system to continuously detect the voice command of the user, and after the vehicle voice recognition system is started, voice signals collected by microphones distributed at each vehicle door and trunk of the vehicle are enhanced and filtered, and then are recognized to Jin standard;
then, for step 102, if the voice command is determined to be a valid command, it is determined whether the voiceprint information of the valid command matches the preset vehicle unlocking voiceprint information, for example, the valid command is "open the door of the cab", "open the door of the co-driver", "open the left rear door", "open the right rear door", and "open the trunk" are valid commands of the vehicle, for example, after the valid voice is determined, it is further determined that the voiceprint information of the valid command performs voiceprint recognition, for example, the voiceprint is a sound wave spectrum carrying speech information displayed by an electro-acoustic apparatus, the generation of human language is a complex physiological and physical process between the human body language center and the vocal organs, and the vocal organs used by the person during speaking, such as the tongue, teeth, larynx, lung, and nasal cavity, have great differences in size and shape, there is a difference in the vocal print patterns of any two persons. The speech acoustic characteristics of each person are both relatively stable and variable, not absolute, but invariant. The variation can come from physiology, pathology, psychology, simulation, camouflage and is also related to environmental interference. However, since the pronunciation organs of each person are different, in general, people can still distinguish different people's voices or judge whether the voices are the same;
finally, to step 103, if effective instruction's voiceprint information with preset vehicle unblock voiceprint information matches, control vehicle unblock, for example, hold under the inconvenient condition of thing, want to open rear door or trunk and want to put the thing under the condition of back seat or trunk, the user says effective instruction "opens the trunk", and vehicle unlocking device speech recognition and voiceprint recognition pass through the back, open the trunk lock and bounce open the trunk.

In the method of the above embodiment, the controlling unlocking of the vehicle includes:
and controlling the vehicle to unlock based on the effective instruction and/or the position information of the vehicle sensing device.
For example, each door and trunk of the vehicle is equipped with a microphone, and a valid command of the user is executed by combining the positional information of the microphone array and the vehicle sensing device, for example, the user speaks a valid command "open the door ahead" in front of the passenger compartment door, and it can be judged that the user is in front of the passenger compartment door by combining the positional information of the microphone array and the vehicle sensing device, and then the vehicle is unlocked and the passenger compartment door is popped open.
In the scheme of this embodiment, by combining the position information of the microphone array and the vehicle sensing device, accurate and effective instruction execution of the user can be realized.
In the method of the above embodiment, after the turning on the vehicle voice recognition system to detect the voice command of the user in response to sensing the vehicle sensing device, the method further includes:
when the vehicle sensing device cannot be sensed by the vehicle, the vehicle voice recognition system is in a closed state.
For example, when a user carrying the vehicle sensing device approaches the vehicle, the vehicle voice recognition system is turned on, and when the user carrying the vehicle sensing device is far away from the vehicle, the vehicle sensing device cannot sense the vehicle, and the vehicle voice recognition system in the turned-on state is turned off until the vehicle sensing device is sensed again.
In the scheme of this embodiment, through vehicle response vehicle induction system start or close vehicle speech recognition system to can realize practicing thrift the electric energy of vehicle battery, improve the life of vehicle battery.
Referring to fig. 2, a flowchart of another vehicle unlocking method according to an embodiment of the present invention is shown, and the flowchart is mainly a flowchart further defined in the step after "determining whether the voice command is a valid command" in embodiment 101.
As shown in fig. 2, in step 201, if the vehicle voice recognition system cannot detect the valid instruction of the user, it is determined whether the valid instruction of the user is detected overtime;
in step 202, if the valid command detection of the user is over time, the vehicle unlocking device is sensed again.
In this embodiment, for step 201, if the vehicle voice recognition system cannot detect the valid instruction of the user, it is determined whether the valid instruction of the user is detected overtime, for example, after the vehicle senses the vehicle sensing device, it is determined whether the valid instruction of the user is detected overtime;
for step 202, if the valid command of the user is detected overtime, re-sensing the vehicle unlocking device, for example, re-sensing the vehicle sensing device after the detection is determined to be overtime, and then restarting the vehicle voice recognition system to continue to monitor the valid command of the user.
In the solution described in this embodiment, when no valid instruction is detected, it is determined whether the detection is overtime, so that the detection can be re-detected after the detection is overtime.
In the method according to the embodiment listed in the above, the determining whether the valid instruction of the user detects a timeout further includes:
and if the effective instruction detection of the user is not overtime, continuously detecting the effective instruction of the user.

The following description is provided to enable those skilled in the art to better understand the present disclosure by describing some of the problems encountered by the inventors in implementing the present disclosure and by describing one particular embodiment of the finally identified solution.
The inventors discovered the defects of these similar techniques in the process of implementing the present invention:
the common characteristics of the modes are that people need to stretch out hands or feet to participate, and more or less modes are not convenient enough in daily life. For example, after shopping, people twist more packages with both hands, and do not have a way to free hands for operation, and the operation can be performed only after the purchased articles are put. If the automobile is parked in an open scene at the moment, the automobile just falls into the rain and is muddy, and the embarrassment is that articles can be placed everywhere.
Mainly, the development of technology, and the technology of voice-based recognition, especially the precise voiceprint recognition technology, has become mature in recent years.
The inventors have found in the course of carrying out the invention why the reason is not easily imaginable:
practitioners mainly focus on the development of a single voice function, with very limited product or field of view of contact;
traditional automobile research personnel are difficult to jump the existing human-computer interaction thinking form, and most of the traditional automobile research personnel are mature designs following the industry;
the concern of safety and reliability is doubtful about the accuracy of the current speech recognition and voiceprint recognition.
The invention has the technical innovation points that:
the microphone arrays distributed on the car doors and the tail boxes are used for pickup, ASR (speech recognition) is carried out after speech signals are enhanced, the car enters a control system, the control instruction of a driver can be accurately recognized, and the legality of a user can be further distinguished through VP (voice print) technology, so that the car is a car owner, a temporary authorized person or an illegal person.
After the automobile is parked and locked, the key induction subsystem is opened by the automobile entry control system and is continuously monitored.
When a user carrying a key approaches the automobile, the key sensing subsystem will first detect the key, thereby starting the voice monitoring subsystem. If the key sensing subsystem does not detect the key, the voice monitoring subsystem is not started.
After the voice monitoring subsystem works, the data collected by the microphones of each car door and the tail box are enhanced by voice signals, and the data are accurately identified after being filtered, so that an instruction given by a user is obtained. Because the induction subsystem can always induce the key, the voice monitoring subsystem can always work even if the user does not send a valid instruction within the specified time; if the owner leaves within the specified time and the key sensing system cannot detect the key, the voice monitoring subsystem stops working, and electric energy is saved.
After the identification instruction result is obtained, the voice monitoring subsystem can further identify the identity of the speaker, if the identity passes the authentication, corresponding operation is carried out by combining the speaker position information given by the array and key sensing subsystem, and if the right rear vehicle door where the user is located is opened. If other unauthorized persons perform voice control, no corresponding operation is given, on the contrary, if the unauthorized persons perform overtime, the system can automatically inform the owner of the vehicle, the images of the unauthorized persons can be sent to the owner of the vehicle by combining with the panoramic image, and the owner of the vehicle can select to alarm according to the images.
After a user carries the key to go away, the key sensing subsystem cannot sense the key, the voice monitoring subsystem can be automatically closed, the electric energy of the battery is saved, and the service life of the battery is prolonged.
Beta version formed by the inventor in the process of implementing the invention:
one solution is based directly on voiceprint control, but is limited by the limitations of the current technology, which cannot guarantee 100% reliability of voiceprints, and under this solution the voice detection subsystem needs to work for a long time, which is a loss for a long-term parked car battery, and is not economical.
The inventor finds that deeper effects are achieved in the process of implementing the invention:
the system can be widely applied to all countries and regions around the world, and only needs to correspondingly update the influence of voice recognition and voiceprint recognition caused by languages and accents. Meanwhile, the system can be popularized to intelligent access control systems of communities, buildings and offices, and has good experience improvement on the current intelligent access control system.
The technical points discovered by the inventor in the process of implementing the invention are as follows:
distributed microphone array voice signal enhancement, voice recognition and voiceprint recognition related to a voice monitoring subsystem in the system use a technology which is thought to be developed independently.
The wireless sensing involved in the key sensing subsystem is a technical solution available in the existing market, such as RFID, NFC, etc.
Referring to fig. 5, a block diagram of a vehicle unlocking device according to an embodiment of the invention is shown.
As shown in fig. 5, the sensing opening determination module 510, the determination module 520 and the unlocking module 530.
The sensing start judging module 510 is configured to start a vehicle voice recognition system to detect a voice instruction of a user in response to sensing a vehicle sensing device, and judge whether the voice instruction is a valid instruction, wherein the vehicle is equipped with the wearable vehicle sensing device, and the vehicle further includes the vehicle voice recognition system and preset vehicle unlocking voiceprint information; a judging module 520, configured to judge whether the voiceprint information of the valid instruction matches the preset vehicle unlocking voiceprint information if the voice instruction is judged to be a valid instruction; an unlocking module 530 configured to control unlocking of the vehicle if the voiceprint information of the valid command matches the preset vehicle unlocking voiceprint information.
