The invention relates to a rapid keyless unlocking system and an unlocking method. The rapid keyless unlocking system is composed of a door handle switch, a vehicle body controller, a low-frequency antenna, an intelligent key, an intelligent key signal receiver, a door module and a door lock. The rapid keyless unlocking method comprises that: a door handle switch is triggered, a door handle switch signal is processed, and the signal is sent to a vehicle body controller; the vehicle body controller drives the low-frequency antenna to emit a low-frequency signal, and the intelligent key is positioned through the low-frequency antenna; after receiving the legal signal, the intelligent key feeds back information to the intelligent key signal receiver through a high-frequency signal, the intelligent key signal receiver transmits the signal back to the automobile body controller, and after the automobile body controller judges that the key is a legal key, the automobile body controller sends an unlocking command to the door module controller through the CAN; and the door module drives the door lock to unlock. According to the rapid keyless unlocking method, rapid unlocking can be achieved, the time for positioning the key is shortened to the maximum extent, and then the rapid keyless unlocking function is achieved.

本发明涉及一种快速无钥匙解锁系统及解锁方法，快速无钥匙解锁系统由门把手开关、车身控制器、低频天线、智能钥匙、智能钥匙信号接收器、门模块和门锁组成；快速无钥匙解锁方法，包括触发门拉手开关，门把手开关信号处理，并发送给车身控制器；车身控制器驱动低频天线发出低频信号，通过低频天线定位智能钥匙；智能钥匙收到该合法信号后，将信息通过高频信号反馈给智能钥匙信号接收器，智能钥匙信号接收器将信号传回车身控制器，车身控制器判断为合法钥匙后，将解锁命令通过CAN发送给门模块控制器；门模块驱动门锁解锁。本发明快速无钥匙解锁方法，可实现快速解锁，使定位钥匙的时间最大程度压缩，进而实现快速无钥匙解锁功能。
