面向发动机台架测试的整车信号模拟系统

为解决发动机台架测试过程中的信号模拟问题，提出面向发动机台架的信号模拟系统，并详细介绍了该系统的硬件、软件及算法实现。该系统主要采用网关实现CAN总线关键信号模拟，通过台架试验验证了系统模拟的信号更准确、同步性更好，可大幅提升试验效率，工程应用较好。

Vehicle Signal Simulation System for Engine Bench Tests

The paper proposed a signal simulation system for engine test benches, and presented the hardware,software and algorithm implementation of the system in detail. The system mainly used gateways to achieve the simulation of CAN bus key signals. The bench test verifies that the simulated signals of the system are more accurate and synchronized,which can greatly improve testing efficiency and the application performance.
