面向多模式操控的汽车电子系统构架及协调控制

Architecture and Coordination Control of Automotive Electronic System Facing Multi-Mode Manipulation

随着汽车舒适性的不断提高,多模式操控方式在汽车上逐步应用.文中提出了面向多模式操控的汽车车身电子控制系统构架及车身电器的协调控制方法,比较了现有的模块化分布式控制系统与智能化全分布式控制系统两种电气系统构架;利用关联子系统的方法实现操控指令与原有逻辑的整合协调分析,并使用数理逻辑和布尔代数方法实现控制逻辑的描述;同时设计了中央协调器及失效安全机制;最后开发了基于智能化全分布式控制系统构架和多模式操控方法的原型样车,证明了文中方法的可行性.

With the continuously improvement of automotive riding comfortability, muki-mode manipulation for automotive body electronics has emerged in recent years. In this paper, first, the architecture and the coordination control method of the electronic system of automotive body facing multi-mode manipulation are proposed. Two types of system architectures, namely the modularized distribution system and the intellectualized completely-distributed system, are compared. Next, an associated subsystem is proposed to analyze the multi-mode manipulation between the implied working logics and the original logics. The symbolic logic as well as the Boolean algebra is used to describe the multi-mode control logic. Central coordination controller and a failure safety mechanism are designed. Finally, a prototype vehicle is developed and tested, from which the proposed architecture and multi-mode manipulation method are proved to be feasible.
