Embodiment Construction

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] Such as figure 1 As shown, the embodiment of the present invention provides a vehicle instrument display test analysis method, the method includes:

[0038] Determine whether the display processing module in the instrument SOC has the data write-back function;

[0039] If so, set the image data write-back parameter, and enable the data write-back function; when the display processing module of the meter SOC sends the processed image data to the meter LCD screen for display, write the image data back to the designated meter SOC in the storage space;

[0040] The image data stored in the specified storage space is read, and the analysis instrument displays the cause of the abnormality.

[0041] When the disp...

Abstract

The invention relates to a vehicle-mounted instrument display test analysis method and system. The method comprises: judging whether a display processing module in an instrument SOC has a data write-back function or not; if yes, setting an image data write-back parameter, and starting a data write-back function; when the display processing module of the instrument SOC sends the processed image data to an instrument liquid crystal screen for display, writing the image data back into a specified storage space of the instrument SOC; and reading the image data stored in the specified storage space, and analyzing an instrument to display an abnormal reason. According to the invention, the display unit of the SOC is controlled by a program to carry out data write-back so as to realize screenshot. Not only is the cost low, but also an abnormal display picture can be restored by 100% through direct data write-back screenshot, and a developer can conveniently carry out problem analysis.

Description

technical field [0001] The invention relates to the technical field of instrument testing, in particular to a method and system for display test and analysis of vehicle instrument. Background technique [0002] With the advancement of technology, full LCD instruments are gradually replacing physical instruments. In the development process of the full LCD instrument, when the display is abnormal, it is necessary to save the abnormal screen for analysis. Currently, high-definition shooting equipment is usually used to capture abnormal images during testing. During the actual development process, the abnormal screen may appear instantaneously, and the screen may not be captured accurately. Moreover, due to the reflection of the liquid crystal screen or the influence of ambient light, it is difficult to ensure the accuracy of the shooting picture, and the test cost is also increased. [0003] Therefore, in order to solve the above deficiencies, a fast screenshot method is dev...
