The invention relates to an awakening system and an automobile, and relates to the technical field of automobiles. The power consumption of the wake-up circuit is reduced. The system comprises a power supply chip, a self-turn-off circuit and a wake-up main circuit. The input end of the self-turn-off circuit is used for receiving a trigger signal. The input end of the wake-up main circuit is connected with the output end of the self-turn-off circuit, and the output end of the wake-up main circuit is further connected with the input end of the power supply chip. The self-turn-off circuit is configured to send a power supply signal to the wake-up main circuit under the condition that the trigger signal is received. The wake-up total circuit is configured to operate upon receipt of a power supply signal. The wake-up main circuit works only when receiving the power supply signal, the power supply signal is sent to the wake-up main circuit only when the self-turn-off circuit receives the trigger signal, and the wake-up main circuit is not in a working state all the time, so that the power consumption is reduced.
本申请涉及一种唤醒系统及汽车,涉及汽车技术领域。旨在降低唤醒电路的功耗。该系统包括电源芯片、自关断电路与唤醒总电路。自关断电路的输入端用于接收触发信号。唤醒总电路的输入端与自关断电路的输出端连接,唤醒总电路的输出端还与电源芯片的输入端连接。自关断电路被配置为在接收到触发信号的情况下,向唤醒总电路发出供电信号。唤醒总电路被配置为在接收到供电信号的情况下工作。唤醒总电路只有在接收到供电信号的情况下才会工作,而只有在自关断电路接收到触发信号的情况下,才会向唤醒总电路发送供电信号,由于唤醒总电路并非一直处于工作状态,因此降低了功耗。
