That is, a modern car cabin system has a multi-screen display scheme, but these screens are output and controlled by a unified cabin domain controller to display, if an instrument screen fails, the instrument screen is only left undisplayed, and since car data displayed by the instrument screen plays a crucial role in driving, a potential safety hazard inevitably exists when a scene that a vehicle has to be driven exists at this time. Based on the method, the device, the electronic equipment and the storage medium, the automobile data of the instrument display screen can be displayed in other screens, and the safety performance of automobile driving is further ensured.
Referring to the attached drawing 1 in the specification, in an embodiment, the application provides a backup method for a display screen of an automobile instrument, which comprises the following steps:
s1, monitoring the display state of a display screen of an instrument in real time;
s2, if the display state of the instrument display screen is monitored to be normal, sending the collected automobile data to the instrument display screen for displaying;
s3, if the display state of the instrument display screen is monitored to be abnormal, an instrument display backup request instruction is generated; and sending the collected automobile data to an on-board display screen for display based on the instrument display backup request instruction.
In order to clearly understand the technical solution of the embodiment of the present invention, an application scenario may be exemplarily described, in the present application, the backup method of the car instrument display screen is applied to a car cabin system, see fig. 2 in the specification, the car cabin system includes a car body controller, a car machine control board and an instrument control board connected to the car body controller, the car machine control board is connected to the car machine display screen, and the instrument control is connected to the instrument display screen, wherein communication between the car body controller and the car machine control board and the instrument control board, communication between the car machine control board and the car machine display screen, and communication between the instrument control board and the instrument display screen are implemented based on communication modes such as PCIE, CAN, ethernet and the like set in the car cabin system, which should be technical means well known by a person skilled in the art, and no detailed description is given here.
In the step S1, the display state of the instrument display screen can be monitored in real time in a self-checking mode. In one embodiment, the detection of the meter display screen is achieved through a meter control board. Specifically, when the automobile is started and the power supply is set to the ON gear, the instrument control panel is electrified to start detecting the backlight state and the display state of the instrument display screen and detecting whether the data between the instrument control panel and the instrument display screen is normally transmitted.
In other embodiments, the display status of the meter display screen may also be monitored by way of user detection, such as the meter display screen being broken, being painted, etc. That is, the meter display operates normally, but for other external reasons, the content displayed by the meter display is obscured or obscured.
In the step S2, when the instrument control panel determines that the display state of the instrument display screen is normal through self-checking and user self-checking, the vehicle body controller transmits the acquired automobile data to the instrument control panel, and the automobile data is processed by the instrument control panel and then transmitted to the instrument display screen for displaying.
In step S3, when the instrument control board finds that the backlight of the instrument display screen is not output, the display is not output, or the data sent to the instrument display screen cannot be transmitted through self-checking, it is determined that the display state of the instrument display screen is abnormal. And after the display state of the instrument display screen is judged to be abnormal, the instrument control board immediately generates an instrument display backup request instruction, and sends the collected automobile data to the vehicle-mounted display screen for displaying based on the instrument display backup request instruction.
Referring to the attached figure 3 of the specification, the method for sending the collected automobile data to the vehicle-mounted display screen for displaying based on the instrument display backup request instruction comprises the following steps:
s301, responding to the instrument display backup request instruction, disconnecting a first transmission channel for receiving automobile data by the instrument display screen, and establishing a second transmission channel for receiving the automobile data by the vehicle-mounted display screen;
s302, the automobile data are sent to the vehicle display screen through the second transmission channel to be displayed.
Specifically, in an embodiment, after the instrument control board generates the instrument display backup request instruction, the instrument display backup request instruction is fed back to the vehicle body controller, and the vehicle body controller responds to the instrument display backup request instruction to disconnect a first transmission channel for transmitting the vehicle data between the vehicle body controller and the instrument control board and establish a second transmission channel for transmitting the vehicle data between the vehicle body controller and the vehicle machine control board; after a second transmission channel for transmitting automobile data between the automobile body controller and the vehicle-mounted machine control panel is to be established, the automobile body controller sends the automobile data to the vehicle-mounted machine control panel through the second transmission channel, and the automobile-mounted machine control panel sends the automobile data to the vehicle-mounted machine display screen for displaying after processing.
If the monitored display state of the instrument display screen is changed from abnormal to normal, the instrument display backup request instruction is eliminated, a second transmission channel for transmitting the automobile data between the automobile body controller and the automobile machine control panel is disconnected, and a first transmission channel for transmitting the automobile data between the automobile body controller and the instrument control panel is recovered, so that the automobile data is changed from the automobile machine display screen to the instrument display screen for display.
In the above embodiment, the first transmission channel for transmitting the automobile data between the automobile body controller and the instrument exists only when the display state of the instrument display screen is abnormal; and a second transmission channel for transmitting the automobile data between the automobile body controller and the automobile machine control panel is temporarily established when the display state of the instrument display screen is abnormal. When the meter display screen fails, the vehicle display screen cannot display the automobile data immediately; when the display state of the instrument display screen is changed from abnormal to normal, the instrument display screen cannot display the automobile data immediately, namely, the short time that the user cannot see the automobile data exists, and the potential safety hazard of driving is increased.
In another embodiment, a first transmission channel for transmitting automobile data between the automobile body controller and the instrument and a second transmission channel for transmitting the automobile data between the automobile body controller and the vehicle-mounted machine control panel are kept open all the time, namely when the display state of the instrument display screen is normal, the automobile body controller transmits the automobile data to the instrument control panel and also transmits the automobile data to the vehicle-mounted machine control panel, at the moment, because no instrument display backup request instruction is generated, the automobile data is only cached in the vehicle-mounted machine control panel and is not transmitted to the vehicle-mounted machine display screen, and the instrument display screen does not display the automobile data, so the automobile data is only displayed by the instrument display screen at the moment; when the display state of the instrument display screen is abnormal, the automobile body controller also transmits automobile data to the instrument control panel and the vehicle machine control panel, the instrument control panel still sends the automobile data to the instrument display screen, the automobile data cannot be seen by a user only due to the fault of the instrument display screen, and meanwhile, due to the fact that an instrument display backup request instruction is generated, the automobile body controller responds to the instrument display backup request instruction and sends the cached automobile data to the vehicle machine display screen for displaying. Therefore, the vehicle display screen is always in a preparation state for displaying the vehicle data, and after the instrument display screen breaks down, a user can immediately see the vehicle data in the vehicle display screen, so that the driving of the user is not influenced, and the safety performance is improved.
If the display state of the instrument display screen is changed from abnormal to normal, the automobile data displayed by the instrument display screen is directly observed by a user, meanwhile, because the instrument display backup request instruction is eliminated, the vehicle-mounted display panel is immediately restored to only cache the automobile data without transmitting the automobile data to the vehicle-mounted display screen, and the vehicle-mounted display screen is restored to the state of only displaying the content of the vehicle-mounted display screen, so that the short time that the user cannot see the automobile data is eliminated, and the potential safety hazard of driving is avoided.
Referring to the specification and the accompanying drawing 4, the car display screen may display car data in a manner that a in the specification and the accompanying drawing 4 shows a manner of dividing the car display screen into a first display area and a second display area, where the first display area is used for displaying car data, the second display area is used for displaying car content, and in order to facilitate a user to observe car data, the first display area is preferably disposed at a position of the car display screen close to a driver seat; a in the attached drawing 4 of the specification shows a mode of arranging a floating window on a car machine display screen, wherein the floating window is used for displaying car data, and when a function in the car machine display screen needs to be operated, if the function is shielded by the floating window, the floating window can be dragged to another position.
In addition, when the display state of the instrument display screen is abnormal, the display state of the instrument display screen also comprises physical damage, such as screen breakage, although the internal structure or circuit of the instrument display screen is not damaged, the user can be influenced to watch the automobile data; or the instrument display screen is coated and covered by the pigment, so that the user cannot watch the automobile data; these conditions are not self-detectable by the body controller. Based on the method, the device and the system, the generation or elimination of the instrument display backup request instruction is controlled by a user independently through setting a key for generating/eliminating the instrument display backup request instruction, so that the purpose of switching the display of the automobile data on the display screen of the automobile or the instrument display screen is achieved. Further improve the backup method of the automobile instrument display screen.
According to the backup method for the automobile instrument display screen, whether the display state of the instrument display screen is abnormal or not is monitored in real time through self-checking, if the display state is abnormal, an instrument display backup request instruction is generated, and the acquired automobile data are sent to the vehicle-mounted display screen to be displayed based on the instrument display backup request instruction, so that the safety performance of automobile driving can be guaranteed in the situation that the instrument screen breaks down and a user has to drive a vehicle.
