摘　　要：采用软硬件协同设计方法,提出基于汽车电子子系统模块化统一建模的动态仿真测试方法。参照汽车电子电控单元参数的匹配方法,提出了基于CCP协议在线调整ABS参数的匹配方法,并从理论上研究了基于MLD(Mixed Logical Dynamical)系统的ABS控制参数自动标定算法。并通过求解MIQP问题为ECU-ABS控制解出一个优化的控制序列。以ABS开发为例进行了说明和测试,对监控标定系统进行了试验,建立了完整的电控参数标定仿真、实验流程。提出的方法对其它汽车电子嵌入式实时软件开发,缩短调试、路试周期具有重要的意义。Adopting an co-design approach of software and hardware, an test approach of dynamical simulation based on modular unified modeling of subsystem of vehicle electronic was put forward. Referring to the matching approach of ECU parameter of vehicle electronic, a matching approach of ABS parameter based on CCP protocol on-line was put forward. From the view point of the theory, an auto-calibrate algorithm for ABS control parameter based on MLD （Mixed Logic Dynamic ） system was researched. And using this model, the optimal control sequence of ECU-ABS control was proposed by solving the MIQP problem. Explaining and testing on an example for ABS development, experimenting monitoring and calibrating system, an integrated simulation and experiment process for electric control parameter was built. It is proved that it is important that a presented approach is adopted for improving software development of embedded real-time system of vehicle electronic, and shortening debugging and experiment periods.
