摘　　要：影响车辆RKE性能的因素非常多,因此汽车制造商在设计RKE功能时必须考虑以上因素。在完成系统匹配、射频测试和功能测试的基础上,要针对市场车辆反馈的各种问题进行深入的研究,以提升系统最终的可靠性。否则系统一旦出现异常,必然导致RKE功能出现各种失效模式。本文针对典型的RKE系统软硬件方面进行了详细的介绍,并针对疑难失效模式进行了详细的分析和改进,从而提升了RKE系统的稳定性。There are many influence elements about the natural capacity of automobile RKE system,such as the stability of RF hardware circuit board,the reliability of decode software,the defect of logical software,the EMC interference according to modified cars,so the automobile manufacturers must consider these elements when designing the RKE system. The automobile manufacturers should make further research after system matching,RF test and function test according to the feedback from the customers,in order to improve the reliability of automobile RKE system. Otherwise, once the system appears disorder,the EKE system＇s function would lead to lose effectiveness. This thesis introduces the hardware of automobile RKE system in detail,analyses and improves some difficult wrong modes, promoting the natural capacity of automobile RKE system。
