The invention provides a wireless wake-up circuit, and particularly relates to the technical fields of automatic driving, intelligent transportation and the like. According to the specific implementation scheme, the wireless wake-up circuit comprises a wireless transceiver module and a power supply control module; the wireless transceiver module receives and detects a wake-up preparation signal sent by an external wireless module, and sends a pre-wake-up signal to the power supply control module when the wake-up preparation signal accords with a fixed format; the power supply control module provides a transmission power supply and an internal public key for the wireless transceiver module after receiving the pre-wake-up signal; the wireless transceiver module sends the internal public key to the external wireless module after the sending power supply supplies power, receives an encrypted wake-up instruction sent by the external wireless module, and then sends the encrypted wake-up instruction to the power supply control module; and the power supply control module decrypts the encrypted wake-up instruction and sends a unit wake-up signal after the encrypted wake-up instruction is successfully decrypted. According to the embodiment, the safety of wireless wake-up of the vehicle is improved.
本公开提供了一种无线唤醒电路,具体涉及自动驾驶、智能交通等技术领域。具体实现方案为:无线唤醒电路包括:无线收发模块和电源控制模块;无线收发模块接收并检测由外部无线模块发出的唤醒准备信号,在唤醒准备信号符合固定格式时,向电源控制模块发出预唤醒信号;电源控制模块在接收到预唤醒信号之后,为无线收发模块提供发送电源和内部公钥;无线收发模块在发送电源供电之后,将内部公钥发送给外部无线模块,并接收外部无线模块发出的加密唤醒指令,再将加密唤醒指令发送给电源控制模块;电源控制模块解密加密唤醒指令,并在加密唤醒指令解密成功之后,发出单元唤醒信号。该实施方式提高了车辆无线唤醒的安全性。
