The invention discloses a whole vehicle power supply network protection system which is arranged between an electrical node KL30 and an electrical node KL30R of two paths of power supplies, isolates a low-function safety level load from an intelligent driving high-function safety level load, and is in a normally closed state. The system diagnoses and detects an electrical node KL30 and an electrical node KL30R of two paths of power supplies of the automobile in real time through software and hardware, and when any path of power supply has a single-point electrical fault, the system can disconnect the electrical node KL30 and the electrical node KL30R of the two paths of power supplies of the automobile; wherein the electrical node KL30 is connected with the positive electrode of the storage battery, and the electrical node KL30R is connected with the positive electrode of the generator. The low-function safety level load and the intelligent driving high-function safety level load are separated, when a single-
