Abstract

The invention relates to a multi-machine automatic test system for body control module (BCM). The system is composed of a power supply, a controller module, an electronic control module and indication module, a CAN module, an I / O test module, a load module, an RF test module, a USB / CAN tool, and an upper computer. The controller module is used for providing power for a tested product in the BCM and distributes a product CAN address and a product ID that are sent by the upper computer to the tested product; the electronic control module and indication module is used for controlling electrification or outage of the tested product in the BCM and indicating a testing result; the CAN module is used for transmitting CAN-format data through a CAN bus; the I / O test module is used for testing an I / O interface of the tested product in the BCM; the load module is used for testing a port drive load of the tested product in the BCM; the RF test module is used for testing receiving and demodulation functions of high-frequency data of the tested product in the BCM; and the USB / CAN tool is used for carrying out mutual conversion on the CAN-format data and a computer-readable data.

Description

technical field [0001] The invention relates to the technical field of test systems for automobile functions, in particular to a BCM multi-machine automatic test system and method. Background technique [0002] Body Control System (BCM) is a system used to realize humanization, comfort and partial safety control of electric appliances on the body, involving vehicle anti-theft, interior lights, electric windows, glass defrosting, wipers, central locking, Control of remote control, turn signals, front and rear combination lights, front and rear fog lights, horns, sunroofs, seats, rearview mirrors, CAN and LIN network communications, etc. [0003] At present, some companies use manual testing and computer self-testing methods. The manual testing method is time-consuming and requires proficiency, and the accuracy and quality cannot be guaranteed. The method of computer self-test has improved accuracy compared with manual test, but it is all based on the test of a single produc...
