Embodiment Construction

[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the Some, but not all, embodiments are invented. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In addition to the above-mentioned problems in the above-mentioned prior art, it should also be noted that some warning lights in the TFT screen of the LCD instrument are self-tested according to whether the specific vehicle is equipped with this function, such as forward collision warning and lane departure warning. For related warning lights, if the vehicle is ...

Abstract

The embodiment of the present invention provides a method and system for detecting a TFT screen alarm light. The method includes: when the ON gear is turned on, the instrument MCU calls the configuration value of the TFT screen alarm light corresponding to the electronic control unit, and sends the configuration value to the instrument. MPU; the instrument MPU dynamically synthesizes each picture in the startup animation and each alarm light picture in the TFT screen into an effect pattern according to the configuration value; the instrument performs real-time refresh according to the synthesized effect pattern, so that the TFT screen alarm light can perform self-test show. The embodiment of the present invention can meet the requirement of real-time display of the self-inspection alarm light according to the configuration value of the MCU and the state of the whole vehicle, and realizes complex self-inspection logic through AND operation; skillfully combines the start-up animation of the TFT screen of the liquid crystal instrument with the self-inspection process of the alarm light Two into one, which greatly shortens the self-inspection time of the alarm light and greatly improves the user experience.

Description

technical field [0001] The invention relates to the technical field of vehicles, and more specifically, to a method and system for detecting a TFT screen warning light. 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 obtain correct information, resulting...
