基于V流程的驱动防滑控制系统控制器设计与试验

Design and Road Tests of ASR Controller Based on the V-flow

对于驱动防滑控制系统(ASR),传统开发方法通过实车道路试验验证控制算法并完成匹配标定,开发周期长、成本高,且必须在完成控制器硬件之后才能实施道路试验,难以满足软硬件并行工程需要。利用V流程方法开发了ASR控制器,研究了ASR系统建模与仿真、快速控制原型、硬件在环仿真实施以及实车试验标定与验证,完成了ECU设计。设计过程和测试结果表明,设计的ECU较好地实现了ASR控制功能,应用V流程设计车辆电子控制系统具有较大的优越性。

For acceleration slip regulation system （ASR）, the traditional method develops the control algorithm through vehicle road experiments, which needs a long period and a high cost. The experiments are only carried on after the development of ECU hardware, which can＇ t meet the requirement of parallel engineering of software and hardware. The ASR controller was developed based on the V-flow method. Then the development of ECU was accomplished, by the modeling and simulation of ASR system, implementation of rapid control prototype （RCP）, hardware-in-the-loop simulation（HILS）, and the vehicle road tests. The research results indicate that the developed ECU can realize the ASR function preferably, and the V-flow developing method is ascendant to develop of the vehicle electronic control systems.
