摘要
为克服汽车底盘各电控单元分立控制所带来的局限性,依托CAN-BUS组建车载网络,从而形成了单元之间的数据传输与共享机制。在此背景下,提出了电控悬架与助力转向单元的系统集成方案,进而完成了相应的CAN-BUS控制节点设计。其中,分别在原有分立控制算法的基础上,建立了电控悬架与助力转向单元的控制系统模型,并通过整车转向动力学模型将因转向而引发的车身侧倾效应导入到了电控悬架单元中加以控制,由此实现了单元的协同控制。最后,通过仿真分析验证系统集成方案的有效性。
To overcome the limitation of independent control of electronic units in vehicle chassis, the paper established an in-vehicle network based on CAN-BUS, and formed a transmission and sharing mechanism among of units. In this background, the paper raised a system integration scheme of electronic control suspension unit and powered steering unit, and then designed the corresponding CAN-BUS control points. Therein, the paper established the model of electronic control suspension unit and powered steering unit which based on the former arithmetic. Then the paper inducted and controlled the roll effects which caused by steering into electronic control suspension through a vehicle steering dynamics model, after this, it implemented the simultaneous control among of units. At last, the paper validated the validity of the system integration scheme by simulations.
