Currently, a user may have a black screen failure on a display of the head-up display device during use of the head-up display device. In the prior art, solutions to the problem of black screen faults mainly surround the angle for reducing the occurrence frequency of black screen faults. For example, a stable and reliable liquid crystal display screen is selected, so that the anti-interference capability of video signals is enhanced from the hardware; or, improving the software design to perfect the functional design as far as possible; or, the pressure test is carried out on the head-up display device before delivery of the head-up display device so as to improve the quality of delivered products. However, the solution to the problem of the black screen fault in the prior art can only reduce the frequency of occurrence of the black screen fault as much as possible, and cannot avoid the occurrence of the black screen fault, and once the display has the black screen fault, only relevant technicians can wait for repair. And the repair of the black screen fault requires a certain time, so that the head-up display device cannot be normally used in a short time, normal driving of a user is affected, and bad driving experience is brought to the user.
Aiming at the problems in the prior art, the embodiment of the application provides a system restarting method, which can ensure the normal starting operation of the head-up display device by restarting the backup partition system when the display of the head-up display device has display faults, thereby reducing the influence of the display faults on the normal driving of a user and improving the driving experience of the user.
The system restarting method provided by the embodiment of the application can be executed by the system restarting device provided by the embodiment of the application, and the system restarting device can be realized in a software and/or hardware mode and is integrated in head-up display equipment for executing the method.
The system restarting method provided by the embodiment of the application is described below with reference to the accompanying drawings.
Referring to fig. 1, a system restart method provided by an embodiment of the present application includes S101-S103:
s101, determining whether a display fault occurs on a display based on at least one display signal of the display of the head-up display device.
Wherein each display signal of the display may be used to characterize a display state of the display. By way of example, the display of the head-up display device in embodiments of the present application may be a liquid crystal display (Liquid Crystal Display, LCD).
For example, in an embodiment of the present application, the display failure of the display may be a black screen failure.
Alternatively, in one possible implementation, the display signal may be a pixel signal of an image presented by a display area of the display. The pixel signal may be a pixel value of a pixel point of the image.
For example, in an embodiment of the present application, an image capturing device (such as a camera) may be disposed on the vehicle, and a capturing field of view of the image capturing device may cover a display area of the display. After the head-up display device is started by a user, the image acquisition device can shoot the display area of the display so as to acquire an image presented by the display area of the display, the acquired image can be transmitted to the head-up display device, and the head-up display device can determine whether the display has display faults or not according to pixel signals of all pixel points in the image. For example, when it is determined that the pixel values of the respective pixels of the image are all 0, it can be determined that the display has failed.
Optionally, in another possible implementation manner, at least one brightness sensor is provided on the display, where each brightness sensor is used to collect a display brightness value at a corresponding position on the display, and each display brightness value is used to represent each display signal.
In an exemplary embodiment of the present application, the luminance sensors may be disposed at the upper right corner position and the lower left corner position of the display, respectively, or may be disposed at the lower right corner position and the upper left corner position of the display, respectively.
In one possible implementation, each display signal is each display luminance value. Taking the example that the brightness sensors are respectively arranged at the upper right corner position and the lower left corner position of the display, when the display brightness value collected by the brightness sensor at the upper right corner position is smaller than the preset brightness value and the display brightness value collected by the brightness sensor at the lower left corner position is smaller than the preset brightness value, the display abnormality can be determined to appear at the upper right corner position and the lower left corner position of the display, and at the moment, the display fault can be determined to appear at the display.
The preset luminance value may be a predetermined light emission intensity value. The preset luminance value may be, for example, 1 candela per square meter (cd/m) 2 Luminescence intensity units).
In the embodiment of the application, the brightness sensor can be arranged on the display, and whether the display has display faults or not can be determined according to the display brightness value of the corresponding position on the display acquired by the brightness sensor. The method for detecting and displaying faults is high in accuracy and low in cost. In addition, in the embodiment of the application, in order to further improve the detection accuracy, a plurality of brightness sensors can be arranged on the display, and the detection result can be determined by combining the display brightness values acquired by the brightness sensors.
Optionally, the head-up display device may further include a main control board, where the main control board includes at least a photoelectric conversion element and a signal processing element; each brightness sensor is used for transmitting each acquired display brightness value to the photoelectric conversion element in real time; the photoelectric conversion element is used for respectively converting each received display brightness value into a corresponding target level signal according to a preset conversion rule and transmitting each target level signal to the signal processing element; and a signal processing element for converting each target level signal into each display signal when each target level signal is received.
Referring to fig. 2, a schematic structural diagram of a head-up display device according to an embodiment of the present application is shown in fig. 2, where the head-up display device includes a display and a main control board, a plurality of luminance sensors are disposed on the display (fig. 2 shows three luminance sensors as an example), and the main control board includes a photoelectric conversion element and a signal processing element. Wherein, a plurality of brightness sensors can be connected with the photoelectric conversion element through wires, and can transmit the optical signals (display brightness values) collected by the brightness sensors to the photoelectric conversion element in real time; the photoelectric conversion element can convert the display brightness value into an electric signal, convert the display brightness value into a target level signal and transmit the target level signal to the signal processing element; the signal processing element may convert the target level signal into a display signal.
In an exemplary embodiment of the present application, the photoelectric conversion element may be a photoelectric Chip, the signal processing element may be a System On Chip (SOC), and the photoelectric Chip may transmit the target level signal to a General-purpose input/output (GPIO) pin of the SOC after converting the display luminance value into the target level signal.
It should be noted that in practical application, the head-up display device according to the embodiment of the present application may further include other components, and only the components related to the technical solution of the present application are described herein, and the structure of the head-up display device is not limited.
Optionally, the photoelectric conversion element is specifically configured to: for the current display brightness value in the received display brightness values, if the current display brightness value is larger than or equal to a preset brightness value, converting the current display brightness value into a high-level signal; if the current display brightness value is smaller than the preset brightness value, converting the current display brightness value into a low-level signal; the signal processing element is specifically configured to: converting the target level signal into a first preset display signal under the condition that the received target level signal is a high level signal; and converting the target level signal into a second preset display signal under the condition that the received target level signal is a low level signal.
The first preset display signal indicates normal display, and the second preset display signal indicates abnormal display. In one possible implementation, in an embodiment of the present application, the display signal may be a register value of a GPIO pin of the SOC. The register value corresponding to the first preset display signal is 1, and the register value corresponding to the second preset display signal is 0.
Exemplary, if the current display luminance value is less than 1cd/m after the photoelectric chip receives the current display luminance value transmitted by a luminance sensor 2 The photo chip may convert the current display luminance value into an optical signal and output a low level signal, for example, may output a 0V low level. The 0V low level can be transmitted to the SOC through the GPIO pin of the SOC, and after the SOC receives the 0V low level, the register value of the GPIO pin can be adjusted to 0, so that the display abnormality of the brightness sensor at the corresponding acquisition position on the display is indicated. Otherwise, if the current display brightness value is greater than or equal to 1cd/m 2 The photo chip may convert the current display brightness value into an optical signal and output a high level signal, for example, may output a 3.3V high level. The 3.3V high level can be transmitted to the SOC through the GPIO pin of the SOC, and after the SOC receives the 3.3V high level, the register value of the GPIO pin can be adjusted to be 1, so that the brightness sensor is indicated that no display abnormality occurs at the corresponding acquisition position on the display.
Optionally, in the embodiment of the present application, luminance sensors may be respectively disposed at four vertex positions of the display.
Referring to fig. 3, a schematic structural diagram of another head-up display device according to an embodiment of the present application is shown in fig. 3, where the head-up display device includes a display and a main control board, and four vertex positions of the display are respectively and correspondingly provided with a luminance sensor, and the main control board includes a photoelectric conversion element and a signal processing element. Wherein, four luminance sensors can be connected with the photoelectric conversion element through wires.
In the embodiment of the application, the display fault is detected by arranging the brightness sensor on the display, and in order to ensure the detection accuracy and reduce the influence of the arrangement of the brightness sensor on the normal display content of the display, the brightness sensors can be correspondingly arranged at the four vertex positions of the display.
In addition, in order to avoid that the brightness sensor shields the projection light of the display, so that the display cannot completely display the content to be displayed, the embodiment of the application can select a hidden brightness sensor.
Optionally, in practical application, external light may flow backward into the brightness sensor, so that the brightness sensor collects a display brightness value and is also a low brightness value under the condition that the display is normally displayed, and thus misjudgment is caused on display faults of the display. Therefore, in the embodiment of the application, the peripheral position of the brightness sensor can be subjected to sealing treatment, so that the influence of backlight can be avoided, the light source collected by the brightness sensor is ensured to be only the display, the accuracy of the display signal collected by the brightness sensor is improved, and the accuracy of detecting the display fault is further improved.
Optionally, determining whether the display has a display failure based on at least one display signal of the display of the head-up display device may include: if the number of the display signals belonging to the second preset display signals meets the preset condition, determining that the display fault occurs in the display; the second preset display signal indicates a display abnormality.
The preset condition may be a predetermined condition. For example, the preset condition may be that the number of the second preset display signals in each display signal is equal to the number of the brightness sensors on the display, that is, each display signal is the second preset display signal.
In practical application, the display content of the display is diversified, so that the situation that the display parameter of the collecting position of the brightness sensor is just a low brightness value may occur, so, in order to further improve the accuracy of detecting the display fault, the embodiment of the application can determine that the display fault occurs in the display when the display brightness values collected by the brightness sensors are all low brightness values, that is, when the display signals are determined to represent that the display state of the display is an abnormal state.
Optionally, in practical application, a display position corresponding to each display content in a display screen of the display may be fixed, and in this case, based on at least one display signal of the display of the head-up display device, determining whether the display has a display failure may further include: determining display signals belonging to a second preset display signal in the display signals as suspected abnormal signals; acquiring at least one history display signal corresponding to the suspected abnormal signal, and determining whether the suspected abnormal signal belongs to a true abnormal signal or a false abnormal signal based on each history display signal corresponding to the suspected abnormal signal; if true abnormal signals exist in the display signals, determining that the display has display faults; and if the true abnormal signals do not exist in the display signals, determining that the display has no display fault.
Each of the history display signals of the suspected abnormal signal may be a display signal determined based on display brightness values acquired by the sensor corresponding to the suspected abnormal signal in the previous acquisition periods.
For example, if a first preset display signal exists in each history display signal of a suspected abnormal signal, it may be characterized that a sensor corresponding to the suspected abnormal signal has collected an excessive brightness value at a corresponding position, and at this time, it may be determined that the suspected abnormal signal is a true abnormal signal; if each history display signal of a suspected abnormal signal is a second preset display signal, the sensor corresponding to the suspected abnormal signal can be characterized to acquire low brightness values at the corresponding position, and at the moment, the suspected abnormal signal can be determined to be a false abnormal signal.

For example, if the failure flag bit is represented by BlackScreen, the preset flag bit may be blackscreen=1. In addition, the failure flag bit defaults to blackscreen=0, that is, blackscreen=0 when the display fails to display a failure.
In the embodiment of the application, when the display faults of the display are determined, the fault zone bit can be modified from BlackScreen=0 to BlackScreen=1, when the system is required to be powered on and restarted, the fault zone bit can be judged first, when the display faults are determined, the operation of switching the partition system is performed, and otherwise, the previous partition system is still started.
In addition, after the system is powered on and restarted based on the backup partition system, the embodiment of the application can reset the fault zone bit and modify the fault zone bit from blackscreen=1 to blackscreen=0.
