Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The invention provides a display control method and device of a central control screen and an automobile, and aims to solve the problem that in the prior art, if a driver wants to open a display screen far away from the driver in a touch screen mode in the driving process, a dangerous accident occurs.

As shown in fig. 1, an embodiment of the present invention provides a display control method for a center control screen, including:

step 11, detecting a voice signal, and acquiring a sound source position and instruction content of the voice signal, wherein the sound source position comprises a main driving position and a non-main driving position, and the instruction content comprises control information applied to a target;

for example, if a driver at the main driving position sends an instruction for opening the application a, the sound source position of the main driving position and the instruction content for opening the application a are obtained; or the passenger at the non-main driving position gives an instruction for opening the application A, and then the sound source position of the non-main driving position and the instruction content for opening the application A are obtained, wherein the non-main driving position comprises the positions of the passenger in the front row and the passenger in the rear row.

And step 12, controlling the display state of the target application according to the sound source position and the instruction content of the voice signal.

For example, when the driver in the main driving position issues an instruction to open the application a, the display state of the application a is controlled to be the open state.

According to the display control method of the central control screen, the sound-emitting position is obtained through the sound source positioning function in voice interaction to distinguish the main driving position from the non-main driving position, the target application is opened or closed after the direction is determined, the target application is displayed at the display position of the central control screen corresponding to the command-emitting person in the optimal size, and a plurality of touch screen actions are completed through one voice command, so that the operation steps of a user are greatly reduced, and particularly for a driver, the method is an interactive means capable of achieving the liberation of two hands. The probability of accidents caused by the fact that a driver touches the central control display screen, particularly the strip-shaped display screen in the driving process is greatly reduced.

Optionally, the display states of the target application in the center control screen include an expanded state and a contracted state, and the screen width occupied by the same application in the expanded state is larger than the screen width occupied in the contracted state.

Specifically, the expansion state includes a full-screen mode expansion and a non-full-screen mode expansion.

As shown in fig. 2, the center control screen is divided into a main driving area close to the main driving position and a sub-driving area far from the main driving position.

The target application is deployed on the central control screen close to the main driving area, so that the operation of a driver is more convenient, and the probability of dangerous accidents caused by the fact that the driver uses the target application while driving a vehicle can be reduced.

Optionally, when the sound source position of the voice signal is a main driving position and the instruction content is that the target application is opened, the step of controlling the display state of the target application includes:

and controlling the target application to be displayed in an expanded state in a main driving area of the center control screen.

For example, when a driver at the main driving position gives an instruction to open the application a, the sound source position of the main driving position and the content of the instruction to open the application a are acquired, and the application a is controlled to be displayed in an expanded state in the main driving area of the center control screen.

Taking a 1 × 6 bar center control display screen as an example, as shown in fig. 3, if the original state of the application a is off, when the driver in the main driving position issues an instruction to open the application a, the application a is displayed in the expanded state 1 × 3 to occupy the entire main driving area.

As shown in fig. 4, if the original state of the application a is open but not displayed on the center control display screen, when the driver in the main driving position issues an instruction to open the application a, the application a is displayed in the expanded state of 1 × 3 to occupy the entire main driving area.

As shown in fig. 5, if the original state of the application a is open but is displayed in the minimum expanded state of 1 × 1 on the center control display screen, when the driver in the main driving position issues an instruction to open the application a, the application a is displayed in the expanded state to occupy the entire main driving area.

As shown in fig. 6, if the original state of the application a is open and displayed in full screen and the original state of the application B is closed, when the driver in the driving position issues an instruction to open the application B and display in full screen, the application B displays the application a in an expanded state instead of the application a, and occupies the entire central control screen.

As shown in fig. 7, if the application a is opened and locked, when the driver in the main driving position issues an instruction to open the application C, the display state of the application a is not affected, and the application C is displayed in the expanded state 1 × 3 close to the main driving area.

Optionally, when the sound source position of the voice signal is a non-primary driving position and the instruction content is that the target application is opened, the step of controlling the display state of the target application includes:

and controlling the target application to be displayed in an expanded state in a passenger driving area of the center control screen.

For example, when a passenger in a non-primary driving position gives an instruction to open the application a, the sound source position in the non-primary driving position and the content of the instruction to open the application a are acquired, and the application a is controlled to be displayed in an expanded state in the secondary driving area of the center control screen.

Optionally, the expanded state includes a full-screen mode and a non-full-screen mode, the full-screen mode is that the display of the target application occupies a full central control screen, and the non-full-screen mode is that the display of the target application occupies a part of a main driving area or a passenger driving area.

Still taking the bar center control display screen of 1 × 6 as an example, as shown in fig. 8, if the original state of the application a is off, when the passenger in the non-primary driving position issues an instruction to open the application a, the application a is displayed in the expanded state of 1 × 3 to occupy the entire passenger driving area.

As shown in fig. 9, if the original state of the application a is open but not displayed on the center control display screen, when the passenger in the non-main driving position issues an instruction to open the application a, the application a is displayed in the expanded state of 1 × 3 to occupy the entire passenger driving area.

As shown in fig. 10, if the original state of the app a is open but the app a is displayed in the minimum deployed state 1 × 1 on the center control display screen, when the passenger in the non-main driving position issues an instruction to open the app a, the app a is displayed in the deployed state 1 × 3 to occupy the entire passenger driving area.

As shown in fig. 11, if the application a is opened and locked, when the passenger in the non-main driving position issues an instruction to open the application C, the display state of the application a is not affected, and the application C is displayed in the expanded state 1 × 3 near the passenger driving area.

Here, as shown in fig. 12, the display modes of the center control display screen also include a double mode, and when the driver or the passenger in the driver's driving position issues an instruction to open the app a, the app a is displayed in the expanded state at 1 × 4 at a position intermediate to the center control display screen.
