Problems solved by technology

[0002] The current instrument display technology uses level signal data collection and level signal to directly control the LED. The disadvantage is that there are too many wiring harnesses and complicated interfaces. When a fault occurs, the detection is extremely cumbersome and cannot meet the current requirements for miniaturization and home furnishing of automobiles.
Moreover, most of the current display instruments use cross coils and ordinary LEDs to display, which consumes a lot of power and has low control accuracy, which has gradually failed to meet the needs of car buyers.

Abstract

A combined electronic meter panel for car is composed of panel and electronic circuits which include main controller chip, shift register, CAN transceiver, memory chip, LCD, step motors, and controller area network and its bus. Its method for processing information includes such steps as self-testing the contents in memory, receiving the bus message, converting the bus signals to the differential signals of main controller, and storing and analyzing the signals to generate relative signals for controlling the display units.

Description

technical field [0001] The present invention relates to a controller local area network bus automotive electronic combination instrument and its information processing method, which relates to an instrument with controller local area network CAN (Controler Area Net) data transmission and control functions applied to automobiles, and is used to control various state. Background technique [0002] The current instrument display technology uses level signal data collection and level signal to directly control LEDs. The disadvantage is that there are too many wiring harnesses and complicated interfaces. When a fault occurs, the detection is extremely cumbersome and cannot meet the current requirements for miniaturization and home furnishing of automobiles. Moreover, most of the current display instruments use cross-coils and ordinary LEDs to display, which consume a lot of power and have low control accuracy, which has gradually failed to meet the needs of car buyers.
