The invention provides a power supply monitoring circuit and method, a power supply circuit and an automatic driving vehicle, and relates to the technical field of electrics, in particular to the technical field of power supply circuits. According to the specific implementation scheme, the power supply monitoring circuit comprises a filter circuit and a controller which are electrically connected; wherein the controller is configured to adjust the cut-off frequency of the filter circuit in response to the change of the load parameter of the current load circuit; the filter circuit is configured to filter the received to-be-monitored power supply signal based on the cut-off frequency to obtain a target power supply signal; the controller is further configured to receive the target power supply signal from the filter circuit and generate a power supply monitoring result based on the target power supply signal. And the adaptability of the power supply monitoring circuit to the hardware environment is improved.

    本公开提供了一种电源监控电路、方法、供电电路及自动驾驶车辆,涉及电气技术领域,尤其涉及电源电路技术领域。具体实现方案为:电源监控电路包括电连接的滤波电路和控制器;其中,控制器被配置为响应于当前负载电路的负载参数发生变化,调节滤波电路的截止频率;滤波电路被配置为基于截止频率,对接收到的待监控电源信号进行滤波,得到目标电源信号;控制器还被配置为从滤波电路接收目标电源信号,并基于目标电源信号生成电源监控结果。提高了电源监控电路对硬件环境的适应性。
