Automatic detection equipment of automobile body control module

Abstract

The invention relates to automatic detection equipment of an automobile body control module. The automatic detection equipment comprises a detection cabinet, a load cabinet and a detection circuit. The detection cabinet and the load cabinet are adjacently arranged. A detection table is arranged on the detection cabinet. The detection circuit comprises a body control module BCM clamp, an industrial control computer, a relay control circuit, a CAN communication module, a simulation load, a program control power supply and a BCM heavy load connector. The BCM clamp is arranged on the detection table and fixes a BCM to be detected. The industrial control computer and the relay control circuit are arranged in the detection cabinet and arranged below the detection table. The simulation load and the program control power supply are arranged in the load cabinet. All the logical functions of the automobile body control module BCM can be efficiently detected through the simulation load, and different load output channels of the BCM can be selectively detected through the relay control circuit so that the detection efficiency is high, the degree of automation is high, the equipment is stable and reliable and the detection result is accurate.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to an automatic detection device for a central control unit of an automobile. Background technique [0002] As a key component of the car, the car central control unit (BCM) has three main functions: [0003] 1. The input switching value of the vehicle (including ignition lock ACC gear, ON gear, START gear, main power switch, fog light switch, small light switch, danger alarm switch, horn switch, brake switch, high beam switch, wiper switch horn button, etc.) and other input conditions for logical function identification and judgment; [0004] 2. According to the specific input conditions, carry out logical control on various types of indicator lights (including low beam, high beam, hazard warning lights, fog lights, etc.), as well as wipers, reversing buzzers, water spray motors, etc. ; [0005] 3. CAN bus communication function, real-time feedback on the bus status...
