Abstract

The invention discloses a CAN bus communication combination system, and relates to the automobile electrical appliance manufacturing industry. The CAN bus communication combination system comprises abody control module (BCM), a CAN transceiver module, an instrument control unit, a liquid crystal display unit, an indicator lamp trigger module, an electronic control unit (ECU) module, an anti-lockbraking system (ABS) module, an electric park brake (EPB) module, an EBS module and an ATM module; the BCM is the whole vehicle control module, all switch control signals of a whole vehicle are inputinto the BCM, and the BCM transmits the switch control signals to the instrument control unit, the ECU module, the ABS module, the EPB module, the EBS module and the ATM module through the CAN transceiver module; and the logic judgment of the instrument control unit is set by a chip, all indicator lamps are triggered to work through the indicator lamp trigger module, and displaying is conducted through the liquid crystal display unit. According to the CAN bus communication combination system, the switch signals of the whole vehicle are transmitted through a CAN, signal transmission and whole vehicle line arrangement between controllers are facilitated, the reliability of the signals is ensured, and the electrical fault is reduced.

Description

technical field [0001] The embodiment of the present invention relates to the automobile electrical appliance manufacturing industry, more specifically, the embodiment of the present invention relates to the trigger control of the CAN communication signal and the indicator light of the vehicle combination meter, especially a CAN bus communication combination system. Background technique [0002] At present, with the improvement of various electronic control functions of trucks, the demand of each controller for each switch signal is increasing, and the required indicator lights are also constantly updated. The original traditional physical instrument has been difficult to meet the demand. Contents of the invention [0003] The object of the present invention is to provide a kind of CAN bus communication combination system for the defects in the above-mentioned background technology, which realizes the transmission of signals between controllers and the wiring layout of the ...
