[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0020] The following detailed description is an exemplary description and is intended to provide further detailed description of the present invention. Unless otherwise indicated, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

[0021] Example 1

[0022] Figure 1 This is a flow chart of a method for switching display modes of a vehicle multi-machine interface according to an embodiment of the present invention, which is applied to a vehicle computer of a target vehicle; wherein the target vehicle includes multiple human-machine interfaces to be switched. Figure 1 As shown, the method specifically includes the following steps:

[0023] Step S102, obtaining a state signal of the environment where the target vehicle is located; the state signal includes a daytime state signal and a nighttime state signal.

[0024] Preferably, the light sensor of the target vehicle senses the status signal of the environment where the target vehicle is located, and then the light sensor sends the status signal to the domain controller DMC of the host through the CAN bus.

[0025] Step S104: When a change in the status signal is detected, start timing a first preset time interval.

[0026] Step S106 , determining whether the status signal changes again after the first preset time interval ends; if not, executing step S108 .

[0027] Specifically, in the embodiment of the present invention, the change of the status signal includes: the status signal changes from a daytime status signal to a nighttime status signal, or the status signal changes from a nighttime status signal to a daytime status signal.

[0028] Step S108 : Sending a display mode switching signal to multiple human-machine interfaces to be switched simultaneously.

[0029] Step S110 , controlling the plurality of human-machine interfaces to be switched to switch the display mode after receiving the display mode switching signal and delaying the switching by a second preset time interval.

[0030] Preferably, if Figure 1 As shown, if timing starts after detecting a change in the status signal, and the status signal changes again within the first preset time interval, the display mode switching is not performed, and the process returns to step S104.

[0031] Preferably, the display modes of the multiple human-machine interfaces to be switched include a day mode and a night mode.

[0032] Specifically, the display mode switching of the multiple human-machine interfaces to be switched includes: the display mode of the multiple human-machine interfaces to be switched is switched from day mode to night mode, or from night mode to day mode.

[0033] Preferably, the first preset time interval is not less than 5 seconds, and the second preset time interval is not more than 3 seconds.

[0034] Preferably, in an embodiment of the present invention, the multiple human-machine interfaces to be switched include: an instrument screen, a central control screen and a co-pilot screen.

[0035] The instrument panel is controlled by the QNX real-time operating system, while the Android control systems for the central control panel and front passenger screen are virtual machines built on the QNX system. Therefore, the switching algorithm must be implemented by QNX: after the vehicle computer receives the CAN signal between night and day, QNX will send a switching message to the module responsible for switching the instrument panel's QNX system UI, and simultaneously notify the Android side of the central control panel and the Android side of the front passenger screen to switch. Due to the differences between the QNX system and the Android operating system, the switching time varies. In addition, the central control panel and the front passenger screen run different applications and resources, and the switching time also varies. It is impossible to grasp the time difference and switch simultaneously. Therefore, the switching between night and day modes of the three screens is out of sync, resulting in a poor user experience. Furthermore, because the vehicle switches immediately when passing under the shade of trees or under an overpass, the frequent switching between night and day affects the user experience.

[0036] In view of the above technical problems, the present invention adds delay processing to the switching logic:

[0037] First, the time difference between the three screen switching processes was clearly defined as less than 3 seconds. Because the instrument panel runs the QNX real-time operating system, the switching speed is very fast. The central control panel, which runs the most applications and consumes the most resources, has the slowest switching process. After running the central control panel multiple times with the most worst-case data, we found that the switching time is 3 seconds, so the switching process is set to 3 seconds. After the QNX system sends the switching message, the instrument panel, central control panel, and passenger panel will time the switching process for 3 seconds, and the switching process will be unified after 3 seconds.

[0038] Then, a delay is designed into the switching logic to solve the problem of frequent night-day switching affecting the user experience due to immediate switching in some scenarios such as passing under the shade of trees or under overpasses. Solution: When receiving the first night-day switching signal, the car computer will first record that no specific mode switch will be made. This will be timed for 5 seconds, and then it will be checked again to see if there is a night-day mode switch. If the day-night mode signal does not change at this time, the three screens will switch modes at the same time after 3 seconds. If the day-night mode signal changes back at this time, the three screens will not switch.

[0039] The 5-second timer was determined through actual measurements and road testing. 1-second and 3-second times are too short, potentially causing a switchover when passing overpasses, overpasses, or under the shade of trees. Times longer than 5 seconds are too long and affect the visual quality. After multiple road tests in real-world scenarios, 5 seconds is the ideal timer.

[0040] From the above description, it can be seen that an embodiment of the present invention provides a method for switching the display mode of a vehicle multi-person machine interface, which adds delay processing to the switching logic, solves the problem of frequent night-day switching affecting the user experience due to immediate switching in some scenes such as passing under the shade of trees or under an overpass; and increases the delayed response time after the multi-person machine interface receives the switching instruction, which can ensure that multiple human-machine interfaces that require different mode switching times can switch modes at the same time, making the switching natural and smooth.

Figure 2 As shown, the system includes: an acquisition module 10 , a detection module 20 , a judgment module 30 and a switching module 40 .

[0043] Specifically, the acquisition module 10 is used to acquire a state signal of the environment where the target vehicle is located; the state signal includes a daytime state signal and a nighttime state signal.

[0044] The detection module 20 is configured to start timing a first preset time interval when detecting a change in the status signal.

[0045] The judging module 30 is configured to judge whether the status signal changes again after the first preset time interval has expired; if not, simultaneously send a display mode switching signal to multiple human-machine interfaces to be switched.

[0046] The switching module 40 is used to control the multiple human-machine interfaces to be switched to switch the display mode after receiving the display mode switching signal, delaying the second preset time interval.

[0047] Preferably, the acquisition module 10 includes a light sensor.

[0048] Preferably, the first preset time interval is not less than 5 seconds, and the second preset time interval is not more than 3 seconds.
