Embodiment Construction

[0025] Such as Figure 1-5As shown, the body control system simulation test system based on CAN bus includes a test bench 1 on which a load subsystem 2 is installed. The load subsystem 2 includes several body electronic devices 21 and / or several simulated body devices 22 distributed on the test bench 1 . The vehicle body electronic equipment 21 and the simulated vehicle body equipment 22 can be set at the same time according to the test requirements, or one of them can be set selectively. In this embodiment, the vehicle body electronic equipment 21 and the simulated vehicle body equipment 22 are provided at the same time. Moreover, the vehicle body electronic equipment 21 includes any one or more of relays, solenoid valves, lights, horns, wipers, meters, and water spray motors. The simulated body equipment 22 includes any one or more of a water temperature signal simulator, an air pressure signal simulator, an oil quantity signal simulator, and an oil pressure simulator, and...

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...
