摘要：

为实现智能车辆的自适应巡航功能,基于模糊逻辑和滑模控制理论设计了具有上下两层结构的自适应巡航控制系统。通过对节气门开度和制动压力进行协调控制,使智能车辆能准确跟踪期望加速度。同时,构建了用于保证该系统控制协调性的切换逻辑曲线。仿真结果表明,自适应巡航控制系统能够使智能车辆在加速行驶、车辆跟踪和制动减速等行驶工况下保持良好的跟踪性和适应性。

Abstract:

In order to realize the adaptive cruise function of intelligent vehicles, an adaptive cruise control system with a two-level structure was designed based on fuzzy logic and slide mode control theory. The system can control throttle angle and brake pressure coordinately so as to make the vehicle follow the desired acceleration command accurately, a logic switch rule between throttle and brake control was also designed to ensure the coordinations of this control system. The simulation results show that the proposed control system provides satisfactory tracking performances and suitability in situations such as traction, vehicle following and braking.

Key words: powertrain system, adaptive cruise control, slide mode control, fuzzy logic
