Problems solved by technology

However, due to the relatively complex display signals of the car dashboard, it is very easy for the staff to make wrong judgments if they repeatedly stare at the signals of the car dashboard. Especially in the face of multiple periodically flashing signals, the accuracy of manual judgment will further decline. The signal detection quality of the car dashboard cannot be guaranteed
In addition, relying on manual detection of the signal of the car dashboard is not only costly but also inefficient
Although some automatic signal detection methods have appeared on the market at this stage, the accuracy of the detection results of these detection methods is generally low

Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a kind of automatic testing method of automobile meter signal, based on the upper simulation device 1 and the automobile dashboard 2 connected with the upper simulation device 1, the automobile dashboard 2 is equipped with a first camera 3 and a second The camera 4 , the first camera 3 and the second camera 4 are respectively electrically connected to the host simulation device 1 .

[0032] A kind of automatic test method of automobile meter signal, specifically comprises the following steps:

[0033] 101. Establish an icon sample database, where the icon sample database includes the display status of each icon on the automobile dashboard 2 in different scenarios.

[0034] In this embodiment, the icon sample database can be established by sequentially collecting the normal display states of each icon on the automobile dashboard 2 in different situations, or it can be directly imported into the existing icon sam...

Embodiment 2

[0051] Such as figure 2 As shown, this embodiment discloses an automated test system for automotive instrument signals, based on the automated test method for automotive instrument signals disclosed in Embodiment 1, including a host simulation device 1 and an automotive instrument panel 2 . The car dashboard 2 is electrically connected with the upper simulation device 1 , and the upper simulation device 1 is used to send instructions to the car dashboard 2 and receive feedback information from the car dashboard 2 . The car dashboard 2 is used to respond according to the instructions sent by the host simulation device 1 , and the car dashboard 2 is equipped with a first camera 3 and a second camera 4 . The first camera 3 and the second camera 4 are respectively used to collect the response information of the automobile dashboard 2, and the response information collected by the first camera 3 and the response information collected by the second camera 4 are respectively transmi...

Abstract

The invention relates to an automatic test method for automobile instrument signals, which comprises the following steps of: establishing an icon sample database which comprises display states of icons on an automobile instrument panel in different scenes; sending an execution instruction to an automobile instrument panel through the upper simulation device; the automobile instrument panel makes amatched response action according to the execution instruction; acquiring and recording the response action through a first camera to obtain first response information; extracting a display state ofthe target icon from the first response information, matching the display state of the target icon with an icon sample database, and determining scene information corresponding to the target icon; verifying whether the scene information corresponding to the target icon is matched with the execution instruction or not, If yes, displaying the target icon normally; otherwise, the target icon is displayed abnormally. According to the test method, automatic detection of signals is realized, the working intensity of test personnel is reduced, the accuracy of signal detection is greatly improved, andthe product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of signal testing, in particular to an automatic testing method for automotive meter signals. Background technique [0002] With the rapid development of the automobile industry, people's dependence on the car dashboard has been increasing. The car dashboard has become an important component of the car, and has experienced a development process from digitalization to intelligence and networking. Today, the car dashboard is no longer just displaying basic information such as vehicle speed, engine speed, fuel level, etc., but the information it can display is quite huge. However, the more complex the system, the greater the possibility of errors in the car dashboard, and the difficulty of detecting the car dashboard will increase accordingly. At present, the detection of the signal of the car dashboard is mainly to manually operate the upper computer of CAN communication on the PC side to send a message to th...
