摘　　要：针对汽车车身控制器研发周期长开发难度大的问题,在恩智浦第二代发动机电子防盗锁止系统(ABIC2)基础上,分析了基站芯片PJF7992A与车身控制器通信过程中的特点及PJF7992A与应答器PCF7961/7938的通信时序,设计了一种基于LIN总线可在不同车身控制器上灵活移植的IMMO软件模块;详细阐述了此软件模块的层次架构、状态转换关系及控制策略,给出可行的移植方法;最后将此模块应用于不同车身控制器平台,验证其可移植性.To solve the problem of long development cycle of body control module,which is also difficult to be developed,based on the second generation Immobilizer system ABIC2 of NXP,the characteristics of the communication process between the base station chip PJF7992A and the body control module BCM is analyzed,as well as the communication time sequence between PJF7992A and the transponder PCF7961/7938. Then a flexible portable IMMO software module which is available in different body control unit based on LIN bus is designed. The hierarchical architecture,state transition relation and control strategy of the software module are described in detail. Finally,this software module is applied to different vehicle body controller platforms to verify its portability.
