Abstract

The embodiment of the present invention provides a TFT screen alarm light self-checking method and device, the method comprising: after the liquid crystal meter is powered on and started, the meter MPU receives the start-up animation play command sent by the meter MCU; according to the start-up animation play command, the TFT screen is controlled to play the following steps: The target start-up animation of the TFT screen alarm light icon; wherein, the target start-up animation is obtained by inserting the alarm light icon into each frame start-up picture of the TFT screen in advance by the instrument MPU within a preset period of time. In the embodiment of the present invention, the alarm light in the TFT screen can complete the self-test when the liquid crystal meter is turned ON for about 3 seconds, displaying the function configuration items of the car, and reminding the driver of the pattern and color of the key electronic control module fault alarm of the whole vehicle. It is convenient for the driver to identify the fault type and severity of each electronic control module of the vehicle during driving.

Description

technical field [0001] The invention relates to the field of self-inspection display of TFT screen alarm lights, and more specifically, to a self-inspection method and device for TFT screen alarm lights. Background technique [0002] The intelligentization, electrification, networking, light weight and sharing of automobiles have increased the number of electronic control components supporting the vehicle, and the connection relationship and control logic between various components have become more complicated. The functions of electronic control systems such as engine operation, automatic transmission shifting, electric power steering, body stability control, and body control systems require the use of various sensors, collectors, processors, and actuators. communicate with each other. If a component of the above-mentioned electronic control system fails, or there is a communication failure between them, it may cause the electronic control unit of the vehicle to fail to ob...
