According to the low-power-consumption wake-up circuit and the vehicle, a communication control circuit is arranged on a Hall system in a steering column of the vehicle in a matched mode, when an operation signal is not detected by a Hall chip, only a first power source supplies power to the Hall chip, the Hall chip works, and a circuit connected with a communication unit and a processing unit does not work; when the Hall chip detects the operation signal, the communication control circuit triggers the second power supply to be connected to the circuit where the communication unit and the processing unit are located and work, and therefore the effect of low power consumption can be achieved.
本发明公开了一种低功耗唤醒电路及车辆,其通过在车辆转向柱内的霍尔系统上配合设置通讯控制电路,当霍尔芯片未检测到操作信号时,只有第一电源对霍尔芯片供电,霍尔芯片进行工作,与通讯单元以及处理单元所连接的电路不工作,当霍尔芯片检测到操作信号时,才通过通讯控制电路触发第二电源接入至通讯单元以及处理单元所在电路中,并进行工作,由此能够达到低功耗的效果。
