The invention provides a power management system for automatic driving and a vehicle, and belongs to the technical field of automatic driving. The system specifically comprises a step-down circuit, at least two communication circuits, at least one voltage transformation circuit and an analog-to-digital conversion circuit. Thestep-down circuit is used for carrying out step-down on an external power supply, and then supplying power to the communication circuits, a central processing unit and the analog-to-digital conversion circuit; the at least two communication circuits are used for receiving data information of external communication equipment through data communication interfaces and transmitting the data information to the central processing unit for forwarding and processing; the at least one voltage transformation circuit is controlled by the central processing unit and is used for carrying out voltage transformation on an external power supply and then supplying power to an external sensor through an output interface; and the analog-to-digital conversion circuit is used for converting the input voltage of the external power supply, the output voltage of the transformation circuit and the voltage of the output interface into a voltage range which can be acquired by the central processing unit. Through the processing scheme provided by the invention, data conversion of equipment of different communication types is realized, the method is suitable for sensors of different voltage platforms and different working voltage ranges, and the universality and the safety are improved.
