Abstract
The invention discloses a theme switching method for an automobile instrument, which is characterized in that a theme switching request is simultaneously sent to an SAFETY process and a QM process; after receiving the theme switching request, the SAFETY process suspends the display of the elements of the SAFETY layer, the QM process switches the theme of the QM layer, and the display of the elements of the SAFETY layer is resumed after the theme switching of the QM layer is completed. According to the automobile instrument theme switching method, when the instrument theme is switched, the display of the SAFETY layer elements is temporarily suspended when the display theme of the QM layer is switched, so that the problem of jumping and flickering caused by asynchronous display of the two layers in the process is thoroughly avoided, and the user experience is improved.
Description
Technical Field
The invention relates to the field of automobile (full liquid crystal) instrument display (HMI (human machine interface), in particular to an automobile instrument theme switching method.
Background
The display layers of the automobile instrument comprise a QM layer and an SAFETY layer, and the QM layer and the SAFETY layer are respectively controlled by a corresponding QM process and a corresponding SAFETY process. The QM layer is a visual effect display layer, is also called a Kanzi layer, is a background layer displayed by the liquid crystal instrument, has a priority lower than that of a SAFETY layer, and is used for displaying element information containing rich visual effects and high rendering load capacity, such as instrument themes, theme switching animations, instrument dials and the like; the SAFETY layer, namely the layer for ensuring the functional SAFETY, is a foreground layer displayed by the liquid crystal instrument, has the highest priority and is used for displaying high-priority image elements related to the functional SAFETY, such as a danger alarm lamp and the like. In the design of the double image layers, the display of the image elements related to the functional SAFETY on the SAFETY image layer is not influenced by the rendering calculation amount of the visual effect elements of the QM image layer, and the reliable display of the image elements related to the functional SAFETY can be still ensured even under the condition of extremely large rendering calculation amount, so that the SAFETY of system display can be ensured while rich visual effects are displayed.
However, because the running period, the control logic and the data of the processes corresponding to QM and safe are independent, synchronization cannot be guaranteed, and the layouts of the image elements corresponding to different display themes and related to functional SAFETY are different, in the process of switching the display themes of the automobile instrument and playing the switching theme animation of the QM layer, the change of the layout of the image elements related to functional SAFETY of the safe layer cannot guarantee synchronization with the theme animation, so that the phenomenon of jump and flicker in vision is caused.
Disclosure of Invention
The invention aims to provide a method for switching themes of an automobile instrument, which can prevent a flicker phenomenon from being caused during theme switching.
The invention relates to an automobile instrument theme switching method, which comprises the following steps:
simultaneously sending a theme switching request to the SAFETY process and the QM process;
after receiving a theme switching request, the SAFETY process suspends the display of the SAFETY layer elements, and the QM process switches the theme of the QM layer;
and after the QM layer completes theme switching, the display of the SAFETY layer elements is recovered.
According to the method for switching the theme of the automobile instrument, when the theme of the instrument is switched, the display of the SAFETY layer elements is temporarily suspended when the display theme of the QM layer is switched, so that the problem of jumping and flickering caused by asynchronous display of the two layers in the process is thoroughly solved, and the user experience is improved.
Detailed Description
An automobile instrument theme switching method comprises the following steps:
simultaneously sending a theme switching request to the SAFETY process and the QM process;
after receiving a theme switching request, the SAFETY process suspends the display of the SAFETY layer elements, and the QM process switches the theme of the QM layer;
and after the QM layer completes theme switching, the display of the SAFETY layer elements is recovered.
And judging whether the QM layer completes the switching of the theme, and judging by the counter value of the theme request sending counter and the counter value of the theme request feedback, wherein the specific implementation mode is that the counter value of the theme request is sent to the QM process, the counter value of the theme request fed back after the QM process completes the switching of the theme is compared with the counter value of the theme request sent to the QM process, and if the counter value of the theme request is equal to the counter value of the theme request sent to the QM process, the display of SAFETY layer elements is recovered.
After the fact that the QM layer completes theme switching is judged, a QM layer switching completion state request is sent to the SAFETY process, and the SAFETY process recovers the display of the SAFETY layer elements.
Setting a minimum time threshold required by theme switching in an SAFETY process, and comparing a time value passed by current theme switching with the minimum time threshold required by QM layer theme switching when the SAFETY process receives a QM layer switching completion state request; if the time value of the current theme switching is smaller than the minimum time threshold required by the theme switching, keeping the state of closing the SAFETY layer; if the time value of the current theme switching is larger than or equal to the minimum time threshold required by the theme switching, the display of the SAFETY layer elements is recovered, and the problem that the visual effect in the theme switching process is influenced by the fact that the display of the SAFETY layer is recovered in advance due to abnormal theme request state updating caused by communication errors among modules can be effectively avoided.
Setting a theme switching overtime time threshold in an SAFETY process, comparing a time value of the current theme switching with the theme switching overtime time threshold when the SAFETY process receives a theme switching request and does not receive a QM layer switching completion state request; and if the time value of the current theme switching is smaller than the time threshold of the theme switching overtime, continuing to monitor the received theme request. When a QM layer switching completion state request is monitored within a theme switching overtime time threshold, the step of comparing the time value of the current theme switching with the minimum time threshold required by the QM layer theme switching is repeated to determine whether to recover the display of an SAFETY layer; when a theme switching request is monitored and a QM layer switching completion state request is not received, repeating the step of comparing the time value of the current theme switching with the theme switching overtime time threshold; if the time value of the current theme switching is greater than or equal to the theme switching overtime time threshold, the display of the elements of the SAFETY layer is recovered no matter whether the theme request received by the SAFETY process is a QM layer switching completion state request or not, and the display of the elements of the SAFETY layer can be ensured to be normally recovered when the QM layer is abnormal, such as QM layer theme switching animation jamming, and the SAFETY of the instrument is further ensured.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
