Problems solved by technology
However, if the power supply is suddenly disconnected during driving, especially at high speed, the power output of the vehicle will be interrupted, which will lead to major driving safety failures.
Therefore, it is relatively easy to cut off in a stationary state, but the problems involved in cutting off in a driving state are more complicated; on the other hand, how to realize the function of power cut-off, because the total current of the vehicle power supply is relatively large, cutting off the main power supply involves the cut-off position Connection reliability, and after power distribution, there are more sub-power circuits to components, and cutting off the sub-power involves too many areas, and there are many control circuits

Embodiment Construction
[0042] An exemplary embodiment of the present invention will be described in more detail below with reference to the accompanying drawings. While the exemplary embodiments of the present invention are shown in the drawings, it is understood that the present invention can be implemented in various forms and is not limited thereto. Instead, these embodiments are provided to be more thoroughly understood, and the range of the scope of the invention can be communicated to those skilled in the art.
[0043] Refer figure 1 The traditional vehicle power distribution system uses the battery 1 and the generator 2 dual power source form, and the battery 1 is used as the main power source at the start of the vehicle, and the generator 2 serves as the main power of the vehicle. The traditional vehicle power architecture connects the battery 1 and the generator 2, and mounts all the electricity equipment below the power source main line 3 of the battery and the generator. When the vehicle is i...

The invention provides a whole vehicle power supply distribution system and method and a vehicle, the protection logic and the implementation mode of power supply cut-off are provided, meanwhile, intelligent power supply monitoring and cut-off protection in the static and dynamic modes of the whole vehicle are achieved by adjusting power supply distribution, and a feasible solution is provided for intelligent monitoring of the whole vehicle power supply. The whole vehicle power supply distribution system comprises a storage battery, a generator electrically connected with the storage battery, a relay which is connected between the storage battery and the generator, a first electric equipment group which is connected between the storage battery and the relay and is related to a vehicle driving function, a second electric equipment group which is connected between the generator and the relay and is related to the non-driving function of the vehicle, and a controller which is connected with the relay.
Description
Technical field [0001] This program relates to the field of power distribution of the vehicle, and is specifically a vehicle power distribution system, method and a car. Background technique [0002] With the continuous improvement of automobile intelligence, the degree of electrification is increasing, the signal interaction between the entire vehicle is more frequent, and in the signal interaction process, it is inevitable that malfunction, etc., causing an abnormal work in the controller. The phenomenon, and the abnormal work of the controller will inevitably accompanied by the abnormality consumption of the whole vehicle, thereby exacerbating battery power loss, causing the failure of the vehicle that the vehicle can't start. With more and more new entertainment functions, such power failure mode is also more prominent. [0003] From the development of the industry, effective measures to solve battery power loss still need to effectively monitor and protect battery power, and...
