摘　　要：车载无钥匙起动控制功能是无线识别技术和车载网络技术的综合应用之一,虽然提高了汽车使用的安全性和便捷性,但其控制信号复杂多样。为了揭示无钥匙起动控制系统工作原理,遵从数字信号时序作用规律,运用逻辑分析法,以奔驰C200轿车的无钥匙起动控制系统为例,全面阐述起动控制系统的“五大”功能,深入剖析控制信号在车载网络中的传输途径,逐步解开起动控制逻辑机理,透彻理顺无钥匙起动控制功能实现过程。不仅为汽车电子产品设计人员应用无钥匙起动控制技术提供经验帮助,也为从事汽车电子控制技术教学和实验人员分析无钥匙起动控制功能提供理论依据。Vehicle keyless start control function is one of the comprehensive applications of wireless identification technology and vehicle network technology. Although it improves the safety and convenience of vehicle use, its control signals are complex and diverse. In order to reveal the working principle of the keyless start control system, comply with the sequence action law of digital signals, take the keyless start control system of Mercedes Bens C200 as an example, this paper uses the logic analysis method to fully expatiate “five major” function of the start control system, deeply analyze the transmission path of control signal in vehicle network, gradually unravel the start control logic mechanism, thoroughly rationalize the realization processs of keyless start control function. It not only provides empirical help for automotive electronic product designers to apply keyless start control technology, but also provides a theoretical basis for automotive electronic control technology teaching and experimenters to analyze keyless start control function.
