[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] like Figure 1-2 As shown, the present application relates to a low-voltage intelligent power distribution system for commercial vehicles. The low-voltage intelligent power distribution system for commercial vehicles includes: an intelligent power distribution control module 10, a display module 20 and an intelligent power distribution fault preprocessing module 30, wherein the intelligent power distribution control module 10 is connected to the display module 20 and the intelligent power distribution fault preprocessing module 30 respectively; by connecting multiple modules in a manner including but not limited to: electrical connection or communication connection, a good electrical signal transmission effect can be achieved, thereby achieving a good coordination effect between modules, and further achieving the effects of multiple functions.

[0027] The intelligent power distribution control module 10 is used to process signals detected and fed back by a number of sensors, and to send control signals to control the actions of other modules, as well as for power distribution and output; it can achieve good control and power distribution effects, thereby achieving the effect of controlling the actions of other modules, and at the same time, it can also achieve the effect of power distribution and output according to usage requirements, thereby achieving precise power control effects, and then achieving improved power utilization.

[0028] The display module 20 is used to display the low-voltage power distribution information and fault information of the whole vehicle in real time; by providing the display module 20, a good display effect can be achieved, thereby achieving a good human-computer interaction effect.

[0029] The intelligent power distribution fault preprocessing module 30 is used to integrate the operation data of the preset vehicles, and to warn the corresponding vehicles with abnormal data, and to push the warning information to the corresponding platform for fault preprocessing. By preprocessing the fault, the corresponding vehicles with abnormal data can be preprocessed, thereby avoiding safety hazards and achieving the effect of improving the safety factor.

[0030] This application can solve the following shortcomings of the existing low-voltage traditional power distribution solution:

[0031] 1. It cannot be self-recovering, and the fuse needs to be replaced after it burns out;

[0032] 2. The fuse specifications are fixed. For example, if a 5A fuse is installed, the protection current is 5A and cannot be changed.

[0033] 3. The fuse specifications are discontinuous, such as the commonly used 5A, 7.5A, and 10A. If the current is 8A, only a 10A fuse can be used;

[0034] 4. The protection characteristics of the insurance cannot change according to the load current. For example, the actual current of the load is constantly changing within a certain range, but the protection value of the insurance is fixed.

[0035] 5. Since the protection characteristics of the insurance change with the ambient temperature, the protection is very inaccurate;

[0036] 6. Due to the poor characteristics of the fuse, a large wiring harness design margin is required during matching to ensure that no wiring harness burnout accidents occur;

[0037] 7. If the matching is wrong, it is very easy to cause the wiring harness to burn out and the insurance to fail to protect the accident;
