1.Summary
1.1 Yi Dingfeng CARSIM_VCU hardware in the loop test system adopts Ni processor supporting platform solution, multi-function board based on vehicle control system related model in the loop simulation and PXI acquisition / output, supports can bus and Ethernet communication, and realizes comprehensive verification and closed-loop test of vehicle controller software function.The platform is convenient for hardware function expansion and modular design, which can shorten the development cycle, reduce software defects and reduce potential risks.
1.2 With NI VeriStand as the core, connected with real-time processor through Ethernet, developed with LabVIEW, TestStand, MathWorks Simulink and other rich function expansion packages. The system is a modular and configurable platform.
2.Advantages of testing solutions
2.1 Real time simulation hardware based on high configuration
(1) It has powerful model calculation ability, and can complete the calculation of all vehicle simulation models on one processor. In this way, the debugging difficulty and real-time synchronization problem of multiple model computing devices are avoided.
(2) It provides an open interface in which the buyer can integrate software and hardware developed independently or by a third party to achieve special functions with high cost performance.
2.2 Cost effective can bus test node
(1) Each can bus port can be individually set to use high speed can or low speed can for communication.
(2) It can easily manage the remaining network simulation.
2.3 White box test seamlessly connected with Inca: it can be seamlessly connected with canape and Inca measurement and calibration system, changing black box test into white box test, reaching unprecedented test breadth and depth.
2.4 High standard vehicle signal generation and measurement
(1) Ni hardware board provides higher precision, larger output current and larger input impedance to meet the needs of high-performance system.
(2) All the main cards are imported directly from the United States, and the quality can ensure the stability and durability of the system.
2.5 Easy to expand modular product components
(1) Professional modular products, such as I / O board box, RTPC, fault injection unit, Bob, standard load simulation box, etc.
(2) Simplify the system integration work, speed up the debugging and operation time, speed up the project switching speed.
(3) It is easy to standardize the wiring harness, which makes the cabinet layout and internal connection more reasonable.
(4) Users can easily expand and upgrade the system by adding modules and wiring harness.
2.6 Professional compact fault simulation module: enables users to carry out real-time fault simulation. Besides short circuit and open circuit, it also provides fault modes such as leakage current, virtual connection and jitter.
2.7 Strict separation of simulation model and hardware interface
(1) When only adjusting the hardware interface without changing the model structure, there is no need to call matlab to compile, which saves valuable time in the system debugging stage.
(2) Transfer the simulation model on different hardware platforms without changing the content of the model itself.
