为了提高四轮转向(4WS)控制技术用于改善汽车操纵稳定性时的有效性,基于硬件在环仿真技术进行4WS车辆快速开发系统的总体方案设计,从仿真计算机软硬件、接口、实际车辆硬件3个方面论述4WS车辆快速开发系统的设计过程;通过纯数字仿真、实时数字仿真、硬件在环仿真以及实车试验验证建立整个4WS车辆控制逻辑快速开发过程。实车道路试验结果表明:改装的4WS轿车的性能优于原来的前轮转向系统,具有较好的操纵稳定性。
In order to improve the effectiveness of 4WS control technology in improving vehicle handling and stability, a 4WS vehicle rapid development system based on hardware-in-the-loop simulation technology is designed. From the simulation of computer hardware and software, interface, actual vehicle hardware In the third part, the design process of 4WS vehicle rapid development system is discussed. Through the pure digital simulation, real-time digital simulation, hardware-in-the-loop simulation and real vehicle test verification, the entire 4WS vehicle control logic rapid development process is established. The actual vehicle road test results show that: modified 4WS sedan performance better than the original front-wheel steering system, with good handling and stability.
