[0010] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0011] In existing technologies, smart cockpits include a variety of in-vehicle smart devices. With so many devices working simultaneously in a closed space, issues such as multiple devices interfering with driving, information hierarchical distribution, and enhancing the overall sense of scene collaboration may arise. Therefore, how to improve intelligence and overall integrity in multi-screen scenarios has become one of the problems that need to be solved.

[0012] To address at least the aforementioned technical problems, this disclosure provides a multi-screen control method. According to embodiments of this disclosure, the driver's smart device distributes vehicle information to one or more in-vehicle entertainment devices via a first multi-screen scene manager. At least one of the in-vehicle entertainment devices processes the vehicle information. If the driver's smart device is offline, a second multi-screen scene manager from one of the in-vehicle entertainment devices is activated to take over the display screen of the driver's smart device and display content associated with the vehicle information on that screen. In this way, collaborative processing by multiple smart devices is achieved, ensuring reliable display of vehicle information in emergency situations, thereby improving the overall integrity and safety of the smart cockpit.

[0013] In the following, the technical solutions according to this disclosure will be described with reference to specific embodiments and in conjunction with the accompanying drawings.

[0014] Figure 1 This is a flowchart illustrating a multi-screen control method 100 according to an embodiment of the present disclosure. (Refer to...) Figure 1 The method 100 includes the following steps 102 to 106.

[0015] In step 102, the driver's smart device distributes vehicle information to one or more in-vehicle entertainment devices through the first multi-screen scene manager.

[0016] In some embodiments, the method 100 may further include the driver's smart device distributing at least one of control information, safety information, and entertainment information to the in-vehicle entertainment device via the first multi-screen scene manager.

[0017] In this way, the driver's smart device distributes vehicle information, control information, safety information, and / or entertainment information to the in-vehicle entertainment system, ensuring information transparency.

[0018] In step 104, the vehicle information is processed by at least one of the in-vehicle entertainment devices. In some embodiments, content associated with the vehicle information is arbitrarily displayed by the passenger-side smart device and the rear multi-screen device. In this way, the passenger-side smart device and the rear multi-screen device can process the received information independently according to the actual situation.

[0019] In step 106, if the driver's smart device is offline, the second multi-screen scene manager of one of the in-vehicle entertainment devices will be activated to take over the display screen of the driver's smart device and display content related to the vehicle information on the display screen.

[0020] In some embodiments, the in-vehicle entertainment device reports its device status to the first multi-screen scene manager. If no response corresponding to the device status is received multiple times, an attempt is made to wake up the second multi-screen scene manager, which is in a dormant state. The target in-vehicle entertainment device corresponding to the first target second multi-screen scene manager to start broadcasts a running message to other in-vehicle entertainment devices, so that the other in-vehicle entertainment devices will no longer attempt to wake up the dormant second multi-screen scene manager. The target in-vehicle entertainment device uses the target second multi-screen scene manager to take over the display screen of the driver's smart device and displays the vehicle information in full screen on the display screen.

[0021] In this way, each smart device has a software backup of the multi-screen scene manager, but only one smart device in the entire network takes on the function of the multi-screen scene manager, namely the driver's smart device, while the multi-screen scene managers of other smart devices are in a dormant state. When the driver's smart device goes offline, the in-vehicle entertainment device will attempt to take on the role of the multi-screen scene manager. This can improve the integrity and safety of the smart cockpit, thereby improving the user experience.

[0022] In some embodiments, after step 106, the method 100 may further include: restarting the offline driver's smart device; and if the offline driver's smart device returns to online, the in-vehicle entertainment device disables the second multi-screen scene manager, no longer taking over the display screen of the driver's smart device, and restores the entertainment function. In this way, the takeover of the display screen of the driver's smart device by an online smart device is only a transitional state. When the offline driver's smart device returns to online, it exits the takeover mode, and the in-vehicle entertainment device restores its entertainment function, thus realizing the interactive collaboration of multiple smart devices.

[0023] In some embodiments, after step 106, the method 100 may further include: if an alarm message is received from an Advanced Driver Assistance Systems (ADAS) system, the in-vehicle entertainment device mutes the system volume and displays the current alarm message using a floating window. In some embodiments, the alarm message includes an alarm type, vehicle status, and related images, wherein displaying the current alarm message using a floating window includes: displaying the alarm type, the vehicle status, and the related images using a floating window. This increases the transparency of vehicle status information, provides drivers and passengers with more vehicle information, reduces anxiety, and thus improves the safety of the smart cockpit.

[0024] In some embodiments, after step 106, the method 100 may further include: if an alarm cancellation message is received from the vehicle's active safety system, the in-vehicle entertainment device restores the system volume and exits the floating window display. In this way, when the alarm is cleared, the in-vehicle entertainment device returns to its normal operating mode, improving the user experience of the smart cockpit.

[0025] Figure 2 This is a flowchart illustrating a multi-screen control method according to an embodiment of the present invention. Figure 2 As shown, the method includes steps 201 to 209.

[0026] In step 201, the driver's smart device distributes vehicle information, control information, safety information, and entertainment information to the in-vehicle entertainment devices, including the passenger's smart device and the rear multi-screen devices, through the first multi-screen scene manager.

[0027] In step 202, at least one of the in-vehicle entertainment devices processes vehicle information, safety information, and entertainment information.

[0028] In step 203, if the driver's smart device is offline, the in-vehicle entertainment device will report the device status to the first multi-screen scene manager. If no response corresponding to the device status is received multiple times, an attempt will be made to wake up the second multi-screen scene manager, which is in a dormant state.

[0029] In step 204, the target in-vehicle entertainment device corresponding to the target second multi-screen scene manager that started running first broadcasts a running message to other in-vehicle entertainment devices so that the other in-vehicle entertainment devices will no longer attempt to wake up the second multi-screen scene manager that is in a dormant state.

[0030] In step 205, the target in-vehicle entertainment device takes over the display screen of the driver's smart device using the target second multi-screen scene manager, and displays the vehicle information in full screen on the display screen.

[0031] In step 206, restart the offline driver's smart device.

[0032] In step 207, if the offline driver's smart device returns to online, the in-vehicle entertainment system disables the second multi-screen scene manager, no longer taking over the display screen of the driver's smart device, and restores the entertainment function.

[0033] In step 208, if an alarm message is received from the ADAS system, the in-vehicle entertainment system will mute the system volume and display the current alarm message using a floating OSD window. The alarm message includes the alarm type, vehicle status, and relevant images.

[0034] In step 209, if an alarm cancellation message is received from the vehicle's active safety system, the in-vehicle entertainment system restores the system volume and exits the floating window display.

[0035] According to another aspect of the present invention, a smart cockpit is provided. For example... Figure 3 As shown, the smart cockpit includes driver-side smart devices, an active safety system, and at least one in-vehicle entertainment device.

[0036] The driver's smart device is configured to distribute vehicle information using the first multi-screen scene manager.

[0037] The car's active safety system is configured to send alarm information.

[0038] At least one in-vehicle entertainment device is configured to mute the system volume and display the alarm information based on the alarm information, and is configured to receive the distributed vehicle information, and when the driver's smart device is offline, to take over the display screen of the driver's smart device using a second multi-screen scene manager, and display content associated with the vehicle information on the display screen.

[0039] In some embodiments, the in-vehicle entertainment system includes a passenger-side smart device and a rear-seat multi-screen device.

[0040] In some embodiments, the driver's smart device, the vehicle active safety system, and the in-vehicle entertainment device are interconnected via a controller local area network (CAN) bus.

[0041] In summary, the multi-screen control method and smart cockpit provided by this invention distribute vehicle information to one or more in-vehicle entertainment devices via a first multi-screen scene manager. At least one of the in-vehicle entertainment devices processes the vehicle information. If the driver's smart device is offline, a second multi-screen scene manager from one of the in-vehicle entertainment devices is activated to take over the driver's smart device's display screen and display content related to the vehicle information. This enables collaborative processing by multiple smart devices, ensuring reliable display of vehicle information in emergencies, thereby improving the overall integrity and safety of the smart cockpit. Furthermore, the takeover of the driver's smart device's display screen by an online smart device is only a transitional state. When the offline driver's smart device returns to online, it exits the takeover mode, and the in-vehicle entertainment device resumes its entertainment functions, achieving interactive collaboration among multiple smart devices. Moreover, when receiving alarm information from the vehicle's active safety system, the in-vehicle entertainment device mutes the system volume and displays the current alarm information in a floating window, increasing the transparency of vehicle status information, providing drivers and passengers with more vehicle information, reducing anxiety, and thus improving the safety of the smart cockpit.
