[0017] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art should fall within the scope of protection of this application.

[0018] Please refer to Figure 1. With the development of intelligent vehicle computers, the same vehicle is often equipped with onboard display devices in multiple locations. For example, as shown in Figure 1, the front row of the vehicle is equipped with an instrument panel screen, a central control screen, and a passenger entertainment screen, and the rear row of the vehicle is equipped with multiple rear entertainment screens. Based on multiple onboard display devices, the use of touch control to achieve user interaction with the vehicle computer is becoming increasingly popular. However, when the vehicle computer system is activated, the touch module of the onboard display device is often in a continuous working state. The onboard display device is easily touched by people in the car, resulting in abnormal display information on the onboard display device and low driving safety. For example, in an actual driving environment, the passenger can operate the central control screen, causing the central control screen to switch the screen and affect the main driver's acquisition of the required information; for example, the rear passenger can also switch the screen information of the rear or front display devices when operating the rear entertainment screen. These behaviors may violate the wishes of the main driver. Another example is the following scenario: the main driver uses the central control screen to display map navigation information. During driving, the main driver accidentally touches the dock bar and the central control screen switches to other screens, or the rear passengers use the shared control of the rear entertainment screen to switch the central control screen to other screens. The above behavior may cause the main driver to lose the map navigation information. On the one hand, it affects the accuracy of driving direction. On the other hand, if the main driver needs to adjust the screen image switched due to accidental touch during driving, it will cause the main driver's vision to be distracted, resulting in unnecessary dangerous driving behavior and low driving safety.

[0019] It is worth noting that, taking the application of touch control in a vehicle-mounted scenario as an example, the introduction of the arrangement and quantity of display devices is only an exemplary display. In actual applications, other arrangements and quantities are not ruled out, and no specific limitation is made on this.

[0020] To address these issues, the present application provides a method for controlling multiple in-vehicle display devices. This method prevents accidental touches on the display devices by occupants during driving, making the touch-activated on / off control of the display devices more consistent with the driver's driving needs. While preventing accidental touches, it still recognizes the user's specific touch needs, improving user experience and driving safety. The control method provided in this embodiment of the present application can be applied to an in-vehicle domain controller, with multiple display devices communicatively connected to the domain controller. As shown in FIG2 , the method includes steps S201 to S202.

[0021] S201: If a first input signal is detected, determine a target display device among a plurality of display devices based on the first input signal, and stop responding to a second input signal received by the target display device, wherein the second input signal is received after the first input signal.

[0022] As an example, the control method of the multi-display device in the vehicle can be used in touch scenarios of multiple display devices in the same vehicle, and can also be used in other control scenarios, such as controlling multiple display devices in the control room, which is not limited in this application.

[0023] As an example, when used in a touch scenario for multiple display devices in the same vehicle, the first input signal may include a shutdown instruction for the interactive function (for example, touch function, gesture interaction function, voice interaction function) of the target display device, and the first input signal may also include a shutdown instruction for the interactive function of all display devices.

[0024] As an example, the second input signal may be a touch signal, or may be a voice control signal, a gesture control signal, or other input signal for controlling the target display device, which is not limited in this application.

[0025] For example, in a touch control scenario involving multiple display devices within a vehicle, the first input signal may include a command to disable interactive functions for the target display device or all display devices, and the second input signal may be a touch signal. By controlling the touch control response of multiple display devices within the vehicle using the first input signal, it is possible to prevent accidental touches on multiple display devices by occupants during driving, further improving driving safety. In other embodiments, the second input signal may also be a voice signal, gesture signal, or mechanical button control for controlling the display devices.

[0026] For example, stopping responding to the second input signal received by the target display device may mean stopping responding to the request information contained in the second input signal received by the target display device, or stopping responding to other information, which is not specifically limited in this application. In some embodiments, stopping responding to the second input signal received by the target display device may mean causing all display devices in the vehicle to stop responding to the second input signal received by the target display device, or may mean that the target display device stops responding to the second input signal received by the target display device.

[0027] As an example, the request information contained in the second input signal received by the target display device may be request information for the user to operate a specific function, such as a request to play or stop music, a request to switch the display screen, a request to adjust the volume, a request to adjust the navigation map destination, and other request information, without specific limitation.

[0028] In some embodiments, for example, a vehicle is configured with an instrument panel screen, a central control screen, a passenger entertainment screen, etc. in the front row, and multiple rear entertainment screens are configured in the rear row of the vehicle. When the driver inputs a first input signal to the vehicle (e.g., the central control screen), the domain controller can determine to turn off the interactive function of the passenger entertainment screen, or turn off the interactive functions of all display devices based on the first input signal. When a passenger on the passenger seat subsequently inputs a second input signal to the passenger entertainment screen, for example, touching the passenger entertainment screen to request to play music, the domain controller does not respond to the touch operation of the passenger entertainment screen, and generates a vibration prompt on the steering wheel, or displays a prompt requesting to play music on the passenger entertainment screen or the central control screen.

[0029] A target display device can be determined from the multiple display devices in a variety of ways. For example, one such determination method may include: each of the multiple display devices has a preset identifier, and the first input signal includes identifier information of the target display device. The identifier information of the target display device included in the first input signal can be compared with the preset identifier to determine the target display device from the multiple display devices. By comparing the identifier information of the display device included in the first input signal with the preset identifier, the display device to be controlled by the first input signal can be quickly and accurately determined from the multiple display devices. In some embodiments, the first input signal can be input via a soft switch on the central control screen, a hardware button on the vehicle, voice input, and / or gesture input. The first input signal inputted via the soft switch on the central control screen may include identifier information indicating the target display device, the first input signal inputted via the hardware button on the vehicle may include a specific definition indicating the target display device, the first input signal inputted via voice input may include semantic information indicating the target display device, and the first input signal inputted via gesture input may include specific gesture information indicating the target display device. According to the identification information of the target display device included in the identified first input signal, by comparing the identification information of the target display device included in the first input signal with a preset identification, the target display device for which touch function control is to be determined among multiple display devices.

[0030] It is worth noting that the above-mentioned method of determining a target display device among multiple display devices is merely an example. In actual applications, other determination methods are not excluded and are not specifically limited thereto.

[0031] There are multiple ways to stop responding to the second input signal received by the target display device. For example, one way to stop responding may include: the target display device can be connected to a domain controller, and the domain controller is used to obtain the second input signal received by the target display device, and can control the domain controller to stop responding to the second input signal received by the target display device. After the touch function of the target display device is turned off, the second input signal received by the target display device will still be uploaded to the domain controller connected to the target display device, but the domain controller will not interact with the request information contained in the second input signal, thereby ensuring that the second input signal can be received while maintaining the touch-off state of the target display device.

[0032] It is worth noting that the introduction of the method of stopping responding to the second input signal received by the target display device is only an example. In actual application, other methods of stopping responding are not excluded and are not specifically limited to this.

[0033] As an example, after stopping responding to the second input signal received by the target display device, a prompt signal can be generated based on the second input signal received by the target display device, and the prompt signal can be sent to the target device so that the target device can provide feedback on the second input signal. The feedback is used to indicate that the interactive function of the target display device (for example, touch function, gesture interaction function, voice interaction function) has been turned off. Although the domain controller does not make an interactive response to the request information of the obtained second input signal, it can instruct other target devices to provide feedback to the user that the interactive function of the target display device (such as touch function, gesture interaction function, voice interaction function) has been turned off for the second input signal itself, so that when the user performs a touch operation on the target display device, he can perceive from the feedback of other target devices that the touch hardware and signal reception of the target display device are normal, and only the touch function of the target display device is temporarily turned off, thereby improving the user experience.

[0034] The target device can have multiple specific implementations, and the target device can also have multiple ways of providing feedback on the second input signal. As an example, the target device can be a steering wheel, and the way the target device provides feedback on the second input signal can be that the steering wheel provides vibration feedback on the second input signal; as another example, the target device can be the target display device itself, and the way the target device provides feedback on the second input signal can be that the target display device provides vibration feedback on the second input signal, or that the target display device provides information display feedback on the second input signal, such as text message prompts, pop-up prompts, animation prompts, etc.; as another example, the target device can be an in-car lighting display device, and the way the target device provides feedback on the second input signal can be that the in-car lighting display device provides light change feedback on the second input signal; as another example, the target device can be a voice output device, and the feedback on the second input signal can also be that the voice output device provides voice feedback on the second input signal.

[0035] S202: If a third input signal is detected, respond to a fourth input signal received by the target display device based on the third input signal.

[0036] As an example, when used in a touch scenario for multiple display devices in the same vehicle, the third input signal includes a touch function activation instruction for the target display device, or the third input signal includes a touch function activation instruction for all display devices.

[0037] As an example, the fourth input signal can be a touch signal, or it can be a voice control signal, a gesture control signal, or other input signal for manipulating the target display device, and there is no specific limitation on this. In some embodiments, when the third input signal is input through a soft switch on the central control screen, and / or a hardware button on the vehicle, and / or voice input, and / or gesture input, the touch function of the target display device can be controlled to be turned on, so that the domain controller can respond to the fourth input signal received by the target display device. For example, when the driver inputs the third input signal to the vehicle (such as the central control screen), the domain controller can determine to turn on the touch function of the co-pilot entertainment screen or turn on the touch function of all display devices based on the third input signal. When the passenger on the co-pilot inputs the fourth input signal to the co-pilot entertainment screen, for example, when the passenger touches the co-pilot entertainment screen to request to play music, the domain controller responds to the touch operation on the co-pilot entertainment screen, causing the music APP on the central control screen to play music, or causing the music APP on the co-pilot entertainment screen to play music.

[0038] As an example, the first input signal and the third input signal may both be signals input by a preset user.

[0039] As an example, the preset user may be the main driving user, the owner of the vehicle, or other types of users, and there is no specific limitation on this.

[0040] As an example, the response to the fourth input signal received by the target display device may be a response to the request information contained in the fourth input signal received by the target display device, such as a request to play or stop music, a request to switch the display screen, a request to adjust the volume, a request to adjust the navigation map destination, and other request information, or it may be a response to other information, which is not specifically limited.

[0041] As an example, when used in a touch scenario for multiple display devices in the same vehicle, the first input signal may include a touch function shut-down instruction for the target display device, the second input signal may be a touch signal or other signal for controlling the target display device, such as a voice input signal or a gesture input signal, the third input signal may include a touch function shut-down instruction for the target display device, and the fourth input signal may be a touch signal or other signal for controlling the target display device, such as a voice input signal or a gesture input signal. By controlling the touch response shut-down and shut-down of multiple display devices in the same vehicle through the input signals, the display device can be prevented from being accidentally touched by people in the vehicle during driving, thereby further improving driving safety.

[0042] In addition, the touch-screen on / off control authority of each display device in the vehicle is limited to preset users, so that the touch-screen on / off control of the display device better meets the needs of the preset users, and the preset users can control the touch-screen on / off control of all display devices in the vehicle, further improving driving safety.

[0043] Determining whether an input signal is input by a preset user can be done in a variety of ways. For example, one such determination method may include obtaining identity information contained in the input signal; and determining that the input signal is input by the preset user if the identity information contained in the input signal matches the preset identity information, wherein the preset identity information can represent the identity of the preset user. Upon receiving the input signal, the vehicle's processor (or domain controller) can compare the pre-stored identity information of the preset user with the identity information contained in the received input signal, thereby quickly and accurately determining whether the input signal is input by the preset user.

[0044] It is worth noting that the introduction of the method of determining that the input signal is a preset user input signal is only an exemplary display. In actual application, other determination methods are not excluded and are not specifically limited to this.

[0045] It can be understood that the method of determining whether the input signal is a preset user input signal described in the embodiment can be applied to the process of determining whether the first input signal or the third input signal is a preset user input signal. In some embodiments, if the first input signal is determined to be a preset user input signal, based on the first input signal, a target display device is determined among multiple display devices, and the response to the second input signal received by the target display device is stopped; if the first input signal is determined to be a signal input by other users, the control of the touch function of the target display device by the first input signal is ignored. Similarly, if the third input signal is determined to be a preset user input signal, the touch function of the target display device is turned on based on the third input signal, and the fourth input signal received by the target display device is responded to; if the third input signal is determined to be a signal input by other users, the control of the touch function of the target display device by the third input signal is ignored.

[0046] The preset identity information, input signal, and identity information contained in the input signal can all have multiple specific implementations. As an example, the preset identity information can be the pre-stored voiceprint information of the preset user, the input signal can be a voice input signal, and the identity information contained in the input signal can be the voiceprint information contained in the input signal; as another example, the preset identity information can be a pre-stored steering wheel signal identifier, the input signal can be the input signal of the steering wheel of the vehicle, and the identity information can be the steering wheel signal identifier contained in the input signal of the steering wheel of the vehicle; as another example, the preset identity information can be a pre-stored preset user account identifier. The input signal may be an input signal from a terminal associated with the vehicle, and the identity information may be an account identifier contained in the input signal from the terminal; as another example, the terminal may be a mobile phone, tablet computer, etc., and the input signal from the terminal may be an input signal from an APP on the mobile phone or tablet computer, and the APP may be bound to the account of the preset user; as another example, the preset identity information may be pre-stored image information of the preset user, and the input signal may be an image signal input by the preset user through an in-car camera, and the identity information contained in the input signal may be image information contained in an image signal input by the preset user through an in-car camera. The specific implementation of the above preset identity information, input signal, and identity information contained in the input signal can limit touch permissions to preset users or driving positions, thereby ensuring driving safety.

[0047] It is worth noting that the introduction of the specific implementation of the preset identity information, input signal, and identity information contained in the input signal is only an exemplary display. In actual application, other specific implementations are not excluded and are not specifically limited to this.

[0048] As an example, the multiple display devices can be a variety of display screens, such as a central control display screen, an instrument display screen, a ceiling display screen, a co-pilot entertainment screen, a rear entertainment screen and other display screens, and there is no limitation on the specific implementation of the display device.

[0049] Please refer to Figures 3 and 4, and the following is an exemplary introduction to the vehicle signal interaction framework and the vehicle signal link structure of an embodiment of the present application.

[0050] In the vehicle-mounted signal interaction framework of the embodiment of the present application, the domain controller can be used to perform signal interaction with various electronic devices, such as the interaction between the steering wheel and the domain controller 1 in Figure 3; if multiple different electronic devices are connected to the same domain controller, then the multiple different electronic devices can use the same domain controller to perform signal interaction. As shown in Figure 3, if the button and the atmosphere light are both connected to the domain controller 1, the button can be used to release the signal to the domain controller 1, and then the domain controller 1 controls the transmission signal of the atmosphere light; if the electronic device is connected to different domain controllers, cross-domain control is required with the help of signal interaction between different domain controllers. As shown in Figure 3, the atmosphere light is connected to the domain controller 1, and the central control display is connected to the domain controller 2. The central control display can transmit the signal to the domain controller 2, and the domain controller 2 then transmits the signal to the domain controller 1, and then the domain controller 1 transmits the signal to the atmosphere light, thereby realizing the control of the atmosphere light by the central control display.

[0051] As shown in Figure 4, the vehicle-mounted signal link structure involved in the touch control interaction in the embodiment of the present application is first introduced. Taking the display device as an example, and taking the second input signal and the fourth input signal as touch signals, after the touch on the display is triggered, the touch coordinate position and pressing force and other information will be transmitted to the domain controller. The hardware abstraction layer (HAL layer) of the domain controller transmits the information transmitted by the display, and the framework layer (FWK layer) judges and processes it and encapsulates it into specific activity events. The application layer (APP layer) packages the event to form a specific required function, and performs function presentation through screen switching of the display and other function presentation devices to realize touch control interaction.

[0052] In an embodiment of the present application, when it is determined that the response to the request information contained in the touch signal received by the target display device has stopped, taking the target display device as an example, the touch signal received by the display screen will be normally transmitted to the hardware abstraction layer of the domain controller, and then transmitted to the framework layer by the hardware abstraction layer; after identifying that the touch function has stopped being enabled, the framework layer does not perform corresponding interactive processing on the request information contained in the touch signal, but generates a prompt signal for the touch signal and sends the prompt signal to the target device, so that the target device provides feedback on the touch signal, until the touch function start instruction contained in the preset user input signal is detected, and then the domain controller is controlled to respond to the request information contained in the touch signal received by the display screen. At this time, the framework layer passes the touch signal to the application layer to restore the touch interaction capability of the display screen.

[0053] It is worth noting that the introduction of the specific application scenarios of the vehicle-mounted signal interaction framework and the vehicle-mounted signal link structure is only an exemplary display. In actual application, other specific application scenarios are not excluded and are not specifically limited to this.

[0054] The technical solution provided by the present application controls the turning on and off of multiple display devices in the same vehicle in response to input signals through input signals, which can prevent the display devices from being misoperated by people in the vehicle during driving, thereby improving driving safety. At the same time, when turning off the input signal response to the target display device, it can still receive the signal input by any user, but only stops responding to the received input signal, thereby avoiding misoperation while still perceiving the user's special control needs, thereby improving the user experience.

[0055] Corresponding to the method embodiment, the embodiment of the present application also provides a control system for multiple display devices in a vehicle, as shown in Figure 5. The system may include multiple display devices 502 and a domain controller 501. The domain controller 501 can be used to: if a first input signal is detected, then based on the first input signal, determine the target display device among the multiple display devices, and stop responding to the second input signal received by the target display device; if a third input signal is detected, then based on the third input signal, respond to the fourth input signal received by the target display device.

[0056] As an example, the first input signal and the third input signal are both signals input by a preset user.

[0057] As an example, the domain controller 501 is used to obtain the identity information contained in the input signal; if the identity information matches the preset identity information, it is determined that the input signal is a signal input by the preset user, wherein the preset identity information can represent the identity of the preset user.

[0058] As an example, the preset identity information includes at least one of the following: pre-stored voiceprint information of the preset user, the input signal is a voice input signal, and the identity information is the voiceprint information contained in the input signal; or a pre-stored steering wheel signal identifier, the input signal is the input signal of the steering wheel of the vehicle, and the identity information is the steering wheel signal identifier contained in the steering wheel input signal; or a pre-stored preset user account identifier, the input signal is the input signal of a terminal associated with the vehicle, and the identity information is the account identifier contained in the input signal of the terminal.

[0059] As an example, the multiple display devices all have preset identifiers, and the first input signal includes identification information of the target display device. The domain controller 501 is used to compare the identification information with the preset identifier to determine the target display device among the multiple display devices.

[0060] As an example, the domain controller can obtain the second input signal received by the target display device, and the domain controller 501 is configured to stop responding to the second input signal received by the target display device.

[0061] As an example, the domain controller 501 is also used to generate a prompt signal based on the second input signal received by the target display device, and send the prompt signal to the target device so that the target device provides feedback on the second input signal, and the feedback is used to indicate that the interactive function of the target display device has been turned off.

[0062] As an example, in a case where the target device is a steering wheel, the target device performing feedback in response to the second input signal includes: the steering wheel performing vibration feedback in response to the second input signal; or

[0063] In a case where the target device is the target display apparatus, the target device performing feedback in response to the second input signal includes: the target display apparatus performing vibration feedback in response to the second input signal; or

[0064] The target display device performs information display feedback based on the second input signal; or

[0065] In the case where the target device is an in-vehicle lighting display device, the target device providing feedback in response to the second input signal includes: the in-vehicle lighting display device providing light change feedback in response to the second input signal; or

[0066] In a case where the target device is a voice output device, the target device performing feedback on the second input signal includes: the voice output device performing voice feedback on the second input signal.

[0067] The present application also provides an electronic device, as shown in Figure 6, which includes: a processor 601; a memory 602 for storing processor-executable instructions; wherein the processor 601 is configured to implement the control method of the in-vehicle multi-display device described in any of the embodiments above.

[0068] The present application also provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, the control method of the in-vehicle multi-display device described in any of the above embodiments is implemented.

[0069] The above are some embodiments of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
