The invention provides an electric automobile awakening system, an electric automobile and an electric automobile awakening method, relates to the technical field of automobiles, and aims to solve the technical problem that the electric automobile awakening system is poor in stability. The electric automobile awakening system comprises a plurality of control units, an input port and an output port of each control unit are connected with a hard wire, all the hard wires are in communication connection, a bus port of each control unit is connected with a CAN bus, and all the CAN buses are in communication connection. The control units receive a first wake-up signal, and the control unit receiving the first wake-up signal is awakened first; and the first awakened control unit awakens other control units through the CAN bus. When one or more of the other control units are not awakened, the first awakened control unit awakens the control unit which is not awakened through the hard wire. Each control unit can receive the first wake-up signal, and the first wake-up signal and the control unit are discretized, so that the stability of the electric vehicle wake-up system is improved.

    本发明提供一种电动汽车唤醒系统、电动汽车及电动汽车唤醒方法,涉及汽车技术领域,用于解决电动汽车唤醒系统稳定性较差的技术问题。电动汽车唤醒系统包括多个控制单元,各控制单元的输入端口和输出端口均连接一条硬线且所有硬线通信连接,各控制单元的总线端口连接一条CAN总线且所有CAN总线通信连接。控制单元接收第一唤醒信号,接收到第一唤醒信号的控制单元第一个被唤醒;第一个被唤醒的控制单元通过CAN总线唤醒其他控制单元。其他控制单元中的一个或者多个未被唤醒时,第一个被唤醒的控制单元通过硬线唤醒未被唤醒的控制单元。各控制单元均可以接收第一唤醒信号,第一唤醒信号与控制单元离散化,提高了电动汽车唤醒系统的稳定性。
