There are a total of 11 combined design principles for functional fuses, which are as follows:

Safety parts must use a separate fuse. Safety parts include both those defined by national standards and those defined by the OEM itself, such as position lights, width lights, low beam lights, etc. It is necessary to configure separate fuses for such parts

Class A important parts (referring to functions essential for controlling the car and running the car safely) must be equipped with separate fuses, such as engine ECU, ABS, etc., which have a great impact on vehicle performance and safety, and other electrical devices that are susceptible to interference from other electrical equipment. , it is necessary to prevent the fuse from being blown due to non-important circuits, causing the car to stall unnecessarily;

Class B generally important parts (referring to functions that are important but do not affect the operation of the car or the safety of the car) are designed to incorporate fuses based on actual use. Such as engine sensors, various alarm lights and external lighting, horns and other electrical devices;

Class C common parts (referring to other functions that bring convenience to automobile use) allow the sharing of fuses. Such as car audio systems, electric heated seats, glove box lighting, electric rearview mirrors, electric window lifting systems, etc. This type of electrical load is not very important to the entire vehicle. Electrical equipment generally added to improve the comfort of drivers and passengers.

Try to avoid sharing insurance when functional parts are installed in different areas of the vehicle;

When merging fuses, you need to consider whether the power supply/communication signals of the functional parts are consistent;

When merging fuses, it is necessary to consider whether there is a connection between functions between functional parts, and consider sharing fuses for related functional parts;

Only electrical appliances with the same load type can share fuses. High and low current circuits (current difference of more than 5A) do not share a fuse;

Loads that do not work at the same time can share the fuse. Some equipment on the vehicle will not work at the same time. In this case, sharing the fuse can improve the utilization of the fuse.

Use separate insurance for dirty current (inductive and capacitive loads, PWM waveform loads, high current loads, etc.) and high current electrical appliances, such as blowers, fans, windows, defrosts, etc.;

The same fuse can be used for impact loads and inductive loads, but cannot be used with weak current loads.
