The invention provides a vehicle controller power source circuit topological structure and a power source management method. The power source circuit topological structure is mainly composed of a 12v power supply system, a 5v power supply system, a 12v to 5v DC/DC, a powering-on and powering-off management circuit, a power source state and fault diagnosis unit circuit and a master control unit, wherein the 12v power supply system provides 12v constant electricity and 12v controllable electricity; the 5v power supply system provides 5v constant electricity and 5v controllable electricity; the powering-on and powering-off management circuit comprises a 12v power supply system powering-on and powering-off management circuit and a 5v power supply system powering-on and powering-off management circuit, and the powering-on and powering-off management circuits include an outer control powering-on and powering-off management circuit and an inner control powering-on and powering-off management circuit according to the different sources of powering-on and powering-off control signals. The vehicle controller power source circuit topological structure and the power source management method resolve the problem of power supply separation of a main chip and an external sensor of an existing vehicle controller and the problem of function limitation caused by unreasonable powering-on and powering-off management.
