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）
驱动防滑控制系统 控制器 硬件在环仿真
2009/12/28
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...
