In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of them. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present invention.
At present, the vehicle-mounted screen is used as a standard of a new vehicle type, and can provide rich driving service and multimedia entertainment service for a vehicle owner. Due to the requirements in different driving environments, the on-board screen often needs to adjust the display direction or the display angle in the vehicle. Various designs of vehicle-mounted screens capable of rotating at different angles exist, however, when a user adjusts the vehicle-mounted screens, the position of the screens is required to be adjusted manually, and the adjustment mode easily causes safety problems during the driving process of the user.
Based on this, the present invention intends to provide a screen adjusting method of a vehicle and a corresponding screen adjusting device of a vehicle, and a computer readable storage medium that overcome or at least partially solve the above problems.
One of the core ideas of the embodiment of the invention is that the automatic regulation and control of the display angle of the vehicle-mounted screen is realized by utilizing the voice instruction, the individual regulation requirements of different users on the display angle of the vehicle-mounted screen in the vehicle use process are met, the manual operation is not needed, the operation is simple and convenient, and the driving safety problem caused by the manual regulation is avoided.
Referring to fig. 1, a flowchart illustrating steps of a method for adjusting a screen of a vehicle according to an embodiment of the present invention may specifically include the following steps:
and 102, receiving the voice of the user and recognizing the voice of the user by the voice assistant to obtain a voice recognition result when the voice assistant is in an awakening state.
In practical applications, a user needs to wake up a voice assistant application program in the vehicle-mounted system, wherein the voice assistant application program has a voice recognition function. In one example, the user may wake up the voice assistant through specific voice instructions; in another example, the user may turn on the voice assistant function by touching a voice assistant function button in the large screen of the vehicle. After the vehicle-mounted system in the vehicle receives the voice of the user, the voice information can be recognized by the voice assistant to obtain a voice recognition result.
And step 104, judging whether the vehicle-mounted screen adjusting condition is met or not according to the user voice.
After the vehicle-mounted system acquires the user voice, the user voice needs to be analyzed to determine whether the adjustment condition of the vehicle-mounted screen is met, specifically, in an example, when the position of the sound emitted by the user voice needs to reach a certain preset position range, the display angle of the vehicle-mounted screen can be adjusted; in another example, the user voice can be set to control the vehicle-mounted screen to rotate when the user voice needs to include parameter information such as a rotating direction, a rotating angle and the like. The adjustment condition of the vehicle-mounted screen can be set by the user according to actual needs in the vehicle-mounted system, and the embodiment of the invention is not limited.
And 106, if the vehicle-mounted screen adjusting condition is met, controlling the vehicle-mounted screen to rotate according to the voice recognition result.
In the embodiment of the invention, the vehicle-mounted screen can rotate around a certain preset rotating shaft so as to meet the watching requirements of people at different positions in the vehicle on the vehicle-mounted screen in different scenes.
In one example, the vehicle-mounted screen can be controlled to rotate at any angle by taking any straight line in any axial direction (including X, Y, Z axes) of the vehicle-mounted screen as a rotating shaft, for example, a central line in the length direction (vertical axial direction) of the vehicle-mounted screen is taken as a preset rotating shaft; in another example, any straight line in any axial direction of the vehicle may also be used as the rotating shaft, and the embodiment of the present invention is not particularly limited thereto.
If the vehicle-mounted screen adjusting condition is met, the information such as the rotating direction and the rotating angle required by the vehicle-mounted screen adjustment can be obtained according to the voice recognition result, and the vehicle-mounted screen is controlled to rotate according to the parameter information and the set rotating shaft. Specifically, the rotation of the vehicle-mounted screen can be realized through a steering adjusting mechanism of the vehicle-mounted screen.
Referring to fig. 2A-2C, the display angle diagrams of the on-board screen in different states are shown, and the front row of the vehicle is provided with a main driving position, a secondary driving position and the on-board screen facing the driving position. The vehicle-mounted screen takes a center line of a vertical axial direction of the vehicle as a preset rotating shaft. As shown in fig. 2A, the display angle is shown in a state where the on-board screen is not rotated, and the on-board screen is oriented to a middle position of the primary and secondary drivers. As shown in fig. 2B, the display angle of the on-board screen is shown when it is turned to the main driving position, in which the turning angle is 20 degrees. As shown in fig. 2C, the display angle of the on-vehicle screen is schematically shown when the on-vehicle screen is turned to the passenger side position, and the turning angle is 20 degrees.
In summary, in the embodiment of the present invention, when the voice assistant is in the wake-up state, the voice assistant may receive the voice of the user and recognize the voice of the user to obtain the voice recognition result; judging whether the received user voice meets the vehicle-mounted screen adjusting condition or not; and if so, controlling the vehicle-mounted screen to rotate according to the voice recognition result. By adopting the method, the automatic regulation and control of the display angle of the vehicle-mounted screen is realized by utilizing the voice command, the individualized regulation requirements of different users on the display angle of the vehicle-mounted screen in the use process of the vehicle are met, the manual operation is not needed, the operation is simple and convenient, and the driving safety problem caused by the manual regulation is avoided.
Referring to fig. 3, a flowchart illustrating steps of another method for adjusting a screen of a vehicle according to an embodiment of the present invention is shown, which may specifically include the following steps:
step 302, when the voice assistant is in the wake-up state, receiving the voice of the user and recognizing the voice of the user by the voice assistant to obtain a voice recognition result.
In this embodiment of the present invention, the voice assistant may be an onboard intelligent voice assistant, and when the onboard intelligent voice assistant is in an awake working state, the voice of the user may be recognized, and particularly, the voice content may be recognized by using a voice recognition method based on an artificial neural network, a probabilistic grammar analysis method, a random model method, a template matching method, and the like, which is not specifically limited in this embodiment of the present invention.
In the embodiment of the present invention, the on-vehicle screen adjustment condition includes a preset position adjustment condition and a preset voice adjustment condition, a microphone array is provided in the vehicle, and voice recognition is performed by installing a microphone with high sensitivity in the vehicle or installing a microphone array system having two or more microphones, so that the voice recognition accuracy can be improved.
Step 304, identifying sound source position information according to the user voice collected by the microphone array.
In practical application, a microphone array installed in a vehicle may be used to take a user's voice and identify sound source location information corresponding to the user's voice. For example, when the co-driver gives a voice command of "see me with large screen", the sound position corresponding to the voice command, i.e., the co-driver position, can be identified by the microphone array.
Step 306, judging whether the sound source position information meets a preset position adjusting condition.
In the embodiment of the invention, when the sound source position information meets the preset position adjustment, the display angle of the vehicle-mounted screen can be adjusted. In one example, the preset position adjustment condition may be that the sound position from which the user speech is emitted is within a range of the front row position of the vehicle, that is, when it is recognized that the sound position is emitted in the front row of the vehicle, the next step may be performed, otherwise it cannot be performed. Due to the difference of the vehicle models, the distances of front row positions corresponding to different vehicles are different, and the front row positions can be specifically set according to different vehicle models.
And 308, if the preset position adjusting condition is met, performing semantic analysis on the voice recognition result to obtain a semantic analysis result.
When the preset position condition is met, the speech recognition result can be subjected to further semantic analysis. The indication information useful for adjusting the vehicle-mounted screen can be extracted from the voice recognition content through semantic analysis. In one example, when the user utters a user voice of "large screen to 50%", the semantic analysis result obtained after the semantic analysis may be "large screen" and "50%".
And 310, judging whether a preset voice regulation condition is met or not according to the semantic analysis result.
In one example, when the user issues a voice command of "turn by 10%", after semantic analysis, the voice command provides only parameter information "10%" indicating the turn angle, which is not in accordance with the preset voice adjustment condition among the vehicle-mounted screen adjustment conditions because it does not explicitly indicate the object to be turned.
In an embodiment of the present invention, with respect to step 310, the following steps may also be included:
a substep S12, determining whether the semantic analysis result includes preset semantic indication information; the preset semantic indicating information comprises rotating object indicating information and rotating parameter indicating information; if the semantic analysis result comprises preset semantic indicating information, judging that a preset voice regulation condition is met;
in practical application, when the semantic analysis result contains preset semantic indicating information, the preset voice adjusting condition of vehicle-mounted screen adjustment can be judged to be met. The specific preset semantic indicating information comprises rotating object indicating information and rotating parameter indicating information.
The rotation object indication information is used for indicating an execution object for rotation, and in the embodiment of the present invention, specifically, refers to a vehicle-mounted screen. In particular, a database may be provided, in which rotating object indication information that may be sent by a user is stored, for example, "vehicle-mounted screen", "vehicle-mounted large screen", "vehicle-mounted center control", etc. refer to words with the same meaning, and all of them may be recognized as rotating object indication information, and may be stored in the corresponding database in advance.
The rotation parameter indication information is used for controlling the vehicle-mounted screen to rotate according to the parameter information.
And step 312, if the vehicle-mounted screen adjusting condition is met, controlling the vehicle-mounted screen to rotate according to the rotation parameter indication information.
And controlling the vehicle-mounted screen to rotate according to the set rotating shaft according to the rotating parameter indication information. In one example, when the vehicle-mounted screen rotates according to the rotating parameter indication information, the rotating position information of the current vehicle-mounted screen is synchronously displayed on the vehicle-mounted screen. For example, the "rotation direction is the co-driving direction and the current rotation angle is 10 degrees" displayed on the screen, and particularly, the rotation position of the current vehicle-mounted screen may also be displayed in other display forms, which is not particularly limited in the embodiment of the present invention.
In an embodiment of the present invention, the rotation parameter indication information includes at least one of: rotation direction indicating information, rotation angle indicating information and rotation scene indicating information.
With respect to step 312, the following steps may also be included:
and a substep S22, determining a rotation angle according to the rotation angle indication information if the rotation parameter indication information includes rotation direction indication information and rotation angle indication information.
In practical application, when the rotation parameter indication information includes rotation direction indication information and rotation angle indication information, for example, "10% for large-screen steering, the voice command includes rotation direction indication information" steering, and includes "10% for rotation angle indication information," the rotation angle that the vehicle-mounted screen needs to rotate can be determined according to "10%".
And a substep S24, determining a rotation angle according to the rotation scene indication information if the rotation parameter indication information includes rotation direction indication information and rotation scene indication information.
In practical application, rotation scenes can be preset, and each preset rotation scene corresponds to a preset rotation angle, for example, the rotation angle of the corresponding vehicle-mounted screen in the scene of the main driving navigation can be set to be 10 degrees towards the main driving direction. When the user voice of 'large screen, main driving navigation' is sent out, the rotation angle corresponding to the preset scene can be recognized to be 10 degrees.
In the embodiment of the invention, the rotation direction indication information, the rotation angle indication information and the rotation scene indication information can be preset in the database, so that the user can conveniently compare and identify the semantic analysis result.
And a substep S26, determining a rotation position according to the rotation direction indication information and determining a rotation angle for the rotation position if the rotation parameter indication information includes rotation direction indication information and does not include rotation angle indication information or if the rotation parameter indication information includes rotation direction indication information and does not include rotation scene indication information.
And a substep S28 of determining a rotation direction according to the rotation direction indicating information.
And a substep S30 of controlling the vehicle-mounted screen to rotate according to the rotating direction and the rotating angle.
