Abstract

The embodiment of the invention provides a TFT screen alarm lamp self-checking method and device. The method comprises the steps that an instrument MPU receives a startup animation playing instructiontransmitted by an instrument MCU after a liquid crystal instrument is powered on and started; and a TFT screen is controlled to play a target startup animation containing a TFT screen alarm lamp iconaccording to the startup animation playing instruction, wherein the target startup animation is obtained by inserting an alarm lamp icon into each frame of startup picture of a TFT screen of an instrument MPU in a preset time period in advance. In the embodiment of the invention, the alarm lamp in the TFT screen can complete self-detection in about 3 seconds of ON gear electricity on the liquid crystal instrument, display function configuration items of the automobile and prompt a driver about patterns and colors of fault alarm of the key electric control module of the whole automobile, so that the driver can conveniently identify the fault type and severity of each electric control module of the whole automobile in the driving process.

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...
