用于车辆电子控制系统开发的仿真环境

介绍了一个用来开发和测试车辆电子控制系统性能的仿真环境.仿真环境模拟真实的交通工况和极限驾驶工况,用于验证车辆电子控制系统中的控制算法,也可以将硬件系统集成到环境里进行硬件在环仿真.首先,介绍了虚拟环境的整体框架和结构.接着,详细介绍了系统的各个组成模块的功能.由于交通环境下仿真车辆感知周围的驾驶环境主要依靠传感器实现,以自适应巡航控制系统为例,介绍了传感器模块和控制模块的集成方法.最后,给出了一个交通环境下自适应巡航控制的例子.

A simulation environment for the test of vehicle electronic control systems

The paper presents a simulation environment for the development and test of vehicle electronic control systems. The virtual reality simulation environment has the ability to simulate traffic driving conditions and critical driving conditions and covers software-in-the loop and hardware-in-the-loop test capabilities. In the hardware-in-the-loop (HiL) configuration, real components such as electronic control units (ECUs) and actuators are embedded in the system. First, the overall framework of the virtual environment is introduced. Then, all components of the system are defined. They build the basis for the entire simulation. Special emphasis is given to the interaction between the simulated vehicle under test and its traffic environment as well as the sensor module radar sensors for example. Finally, gives an example of Adaptive Cruise Control (ACC) under traffic conditions.
