Car body control system simulation test system based on controller area network (CAN) bus

Abstract

The invention belongs to the electronic technical field, and relates to a car body control system simulation test system based on a controller area network (CAN) bus, which solves the technical problem of the prior art that the design is unreasonable. The test system comprises a test rack, wherein the test rack is provided with a load subsystem, the load subsystem comprises a plurality of car body electronic devices and / or a plurality of simulation car body devices which are installed on the test rack, the load subsystem is connected with at least one body control module (BCM) through a connection module, the BCM is respectively connected onto the CAN bus, the connection module comprises a switch array, and each switch of the switch array is respectively provided with a detachable connection terminal. The car body control system simulation test system has advantages that the car body electronic device and / or the simulation car body devices in the load subsystem can be conveniently connected to the test system or can be conveniently ruled out of the test system through the connection module, so that the influence of each car body electronic device and / or each simulation car body device on the car body control system can be detected.

Description

technical field [0001] The invention belongs to the field of electronic technology and relates to a test system, in particular to a simulation test system for a body control system based on a CAN bus. Background technique [0002] With the development and progress of the automobile industry, people put forward higher requirements on the power, economy, safety and emission of automobiles. Traditional mechanical control systems are far from being able to meet these needs. With its high precision, high speed, flexible control, stability and reliability, the electronic control system has gradually replaced the mechanical control system and has become the development trend of the automotive control system. Due to the high requirements on real-time performance, control accuracy and reliability of the automobile control system, the complexity of the electronic control system program of the automobile body is getting higher and higher, and repeated debugging is required in the deve...
