Optionally, the user identity may be identified before the instruction identification is performed based on the audio data, and the processing may be as follows:
the controller 5 extracts first voiceprint information of the audio data after acquiring the audio data detected by the sound detection section 4. The controller 5 determines the voiceprint information matched with the first voiceprint information in the correspondence between the previously stored voiceprint information and the account identifier. If the controller 5 detects the voiceprint information matched with the first voiceprint information, it is determined that the identity recognition is successful, that is, the current user is the user added with the voiceprint information and has the authority of performing voice control on the automobile.

At this time, the prompt information of the failure of the identification can be displayed on the display screen to inform the user that the automobile can not be controlled by voice.
The following explains the processing procedure of adding voiceprint information by the user:
in the controller 5, a correspondence table between the voiceprint information and the account identifier may be established in advance. The initial state of the correspondence table may be empty. The user can register the account of the user and add the voiceprint information of the user in the corresponding relation table.

The controller 5 receives a trigger instruction (which may be called a voiceprint adding instruction) for the option, and the controller 5 may display a prompt message on the display screen to prompt the user to read some specified content. The controller 5 acquires a second voice signal acquired by the microphone within a preset time, extracts voiceprint information of the second voice signal, and adds the voiceprint information of the second voice signal and the account identifier of the current login account of the user into the corresponding relation table of the voiceprint information and the account identifier.
Optionally, the options may not be set in the display interface of the display screen, an entity button may be set on the controller, and the user may directly trigger the voiceprint addition instruction by clicking the entity button.
402. If the audio data received by the controller 5 is voice data triggering the opening of the back door 2, the electric push rod 31 is controlled to extend to control the opening of the back door 2, and if the audio data received by the controller 5 is voice data triggering the closing of the back door 2, the electric push rod 31 is controlled to shorten to control the closing of the back door 2.
The specific processing of step 402 can be implemented in many ways, and several of them are described below:
in a first mode
The controller 5 performs voice recognition on the audio data to obtain target character data. The controller 5 determines the degree of matching of a plurality of key data stored in advance for triggering the opening or closing of the back door 2 with the target character data, respectively. And if the maximum matching degree is greater than the threshold value of the matching degree and the keyword data corresponding to the maximum matching degree is the keyword data for triggering the opening of the back door 2, controlling the electric push rod 31 to extend so as to control the opening of the back door 2. If the maximum matching degree is greater than the threshold value of the matching degree and the keyword data corresponding to the maximum matching degree is the keyword data for triggering the closing of the back door 2, the electric push rod 31 is controlled to be shortened so as to control the closing of the back door 2.
The controller 5 receives the audio data, inputs the audio data into the trained speech recognition model, and the speech recognition model decodes the audio data and outputs the recognized target character data. The controller 5 controls the movement of the electric putter 31 based on the target character data recognized by the voice recognition model. Wherein the speech recognition model may be a machine learning model.
A correspondence table of the relevant key data and the control types is established in advance in the controller 5, as shown in table 1 below, in which at least one key data corresponding to each control type is recorded. The control types may include an open back door type and a close back door type, and may also include other control types such as turning on an air conditioner, turning on a radio, and the like.
TABLE 1
The controller 5 performs voice recognition on the audio data to obtain target character data. The matching degree of each keyword data and the target character data in the correspondence table can be calculated. And if the maximum matching degree is greater than the threshold value of the matching degree, determining the target control type corresponding to the target key data with the maximum matching degree in the corresponding relation table. If the target control type is an open back door type, the electric push rod 31 is controlled to extend to control the back door 2 to open. If the target control type is a closed back door type, the electric push rod 31 is controlled to be shortened to control the back door 2 to be closed.
Mode two
The controller 5 inputs the audio data into the trained control type recognition model to obtain the control type corresponding to the audio data. If the control type corresponding to the audio data is the type of opening the back door, the electric push rod 31 is controlled to extend to control the back door 2 to be opened, and if the control type corresponding to the audio data is the type of closing the back door, the electric push rod 31 is controlled to shorten to control the back door 2 to be closed.
Optionally, the process of training the control type recognition model may be to collect a large amount of audio data about controlling the opening and closing of the back door of the automobile as sample audio data, and manually mark the reference control type. And inputting the sample audio data into the control type identification model, and outputting the prediction control type by the control type identification model. Based on the reference control type and the predictive control type, a loss value is determined. And training and adjusting parameters of the control type recognition model based on the loss value. And processing each sample audio data in the above manner until a training end condition is met, so as to obtain a trained control type recognition model. The training end condition may be arbitrarily set based on the requirement, for example, a target training number is reached, or a certain number of consecutive loss values are smaller than a preset loss value threshold, or a certain number of consecutive predictive control types are the same as the reference control type, or the like.
Optionally, after the controller 5 identifies the voiceprint information of the audio data and identifies the account identifier corresponding to the audio data, the controller 5 may determine the stroke value of the electric push rod 31 according to the account identifier in the process of controlling the back door 2 to be opened, and control the electric push rod 31 to extend.
After recognizing that the account identifier corresponding to the voiceprint information matched with the voice data is the first account identifier, the controller 5 determines a first travel value corresponding to the first account identifier in the correspondence between the prestored account identifier and the travel value of the electric push rod 31. And if the audio data is voice data triggering the opening of the back door 2, controlling the electric push rod 31 to extend by a first travel value.
The processing procedure for adding the run value is explained in detail below:
in implementation, an option of adding a travel value may be set in a display interface of the display screen of the controller 5, and the user may trigger the option by an operation, for example, clicking the option by a touch operation, or triggering the option by a physical key. The controller 5 receives a trigger instruction (which may be referred to as a travel value adding instruction) of the option, and the controller 5 may display a prompt message on the display screen to prompt the user to input a travel value for the currently logged-in account. The controller 5 may also prompt the user to enter a trip value via a notification light on the vehicle body. The user input stroke value may be a numerical value directly input into the stroke value or may be selected from a plurality of numerical values. When the user inputs the travel value, the controller 5 stores the travel value in correspondence with the account identifier of the currently logged-in account.
Optionally, the options may not be set in the display interface of the display screen, an entity button may be set on the controller 5, and the user may directly trigger the trip value adding instruction by clicking the entity button.
All the above optional technical solutions may be combined arbitrarily to form the optional embodiments of the present disclosure, and are not described herein again.
The above description is only exemplary of the present application and should not be taken as limiting the scope of the present application, and any modifications, equivalents, improvements and the like that are within the spirit and principle of the present application should be included in the scope of the present application.
