摘要
提出了一种电动机模型和动态安全距离模型,并在Carsim平台上搭建纯电动汽车整车动力学模型.设计了模糊距离控制器,并建立Simulink和Carsim联合仿真平台,在该平台上对纯电动车辆模糊距离控制器进行仿真分析.结果表明:同没有控制器的车辆相比,被控车辆能始终保证同前车车距在5m以上的安全距离,同前车起始车距在50,80,100m车距时均能将两车的最小距离控制在5m以上,相邻车道切入工况下也能够有效防止追尾事故,避免碰撞,提高了车辆的主动安全性和道路的通过效率.
The motor model and the dynamic safety distance model were proposed, and the vehicle dynamics model of pure electric vehicle was built on the Carsim platform. The fuzzy distance controller was designed, and the Simulink and Carsim joint simulation platform was established to conduct the simulation analysis of the pure electric vehicle fuzzy distance controller. The results show that the controlled vehicle can ensure the safe distance more than 5 m from the preceding vehicle compared with the vehicle without controller. When the starting distance of preceding vehicle are 50,80 and 100 m, the minimum distance can be controlled more than 5 m. Under the condition of cutting in the adjacent lanes, the rear-end collision and other collisions can be effectively prevented, and the active safety of vehicle and the efficiency of road passage can be greatly improved.
