汽车无源识别系统涉及汽车电子,尤其涉及汽车无源钥匙识别系统,具体涉及RKE和PKE在识别器无电源或低电源供电情况下,可以通过无源芯片实现无钥匙进入车辆的系统。无源识别系统利用电磁感应原理和电容充放电技术结合数据加密技术研究而成。在识别器处于低电状态时,利用电感给电容充电来替代电池供电的系统。
Automotive passive identification systems are concerned with automotive electronics, and in particular with automotive passive key recognition systems, and in particular with systems where RKE and PKE can realize keyless entry vehicles with passive chips in the absence of power or low power supply. Passive identification system uses the principle of electromagnetic induction and capacitor charging and discharging technology combined with data encryption technology research. When the recognizer is in a low-power state, the inductor is used to charge the capacitor instead of the battery-powered system.
