acquiring vehicle information of a vehicle, the vehicle information comprising vehicle brand information, vehicle model information, and vehicle configuration information; determining, according to the vehicle information, parts or modules included in function systems of the vehicle; acquiring, from a pre-established element database, elements corresponding to the parts or modules included in each function system, wherein the element database includes element information about a plurality of elements, each of the elements corresponds to one part or module, and the element information includes element codes and element pictures; acquiring connection relation information between the parts or modules included in the function systems and vehicle buses, and signal flow direction information between the parts or modules; and generating, according to the element information of the elements corresponding to the parts or modules included in the function systems, the connection relation information and the signal flow direction information, system illustrations corresponding to the function systems of the vehicle.

2 . The method according to claim 1 , wherein the element database comprises a plurality of element groupings, each of the element groupings consists of the elements corresponding to the parts or modules having the same operating principle, and the same element picture in each of the element groupings corresponds to one or more element codes.

3 . The method according to claim 2 , wherein the element database further comprises a mapping relation between each element and vehicle brand information, and/or vehicle model information, and/or function system identifier, and the acquiring, from a pre-established element database, elements corresponding to the parts or modules included in each function system comprises:
acquiring, from a pre-established element database, elements corresponding to the parts or modules included in each function system of the vehicle according to the vehicle information and each of the function system identifiers.

4 . The method according to claim 1 , wherein the generating, according to the element information of the elements corresponding to the parts or modules included in the function systems, the connection relation information and the signal flow direction information, system illustrations corresponding to the function systems of the vehicle comprises:
generating, according to the element information of the elements corresponding to the parts or modules included in the function systems and the connection relation information, network architectures corresponding to the function systems of the vehicle, and generating, according to the element information of the elements corresponding to the parts or modules included in the function systems and the signal flow direction information, signal architectures corresponding to the function systems of the vehicle.

5 . The method according to claim 4 , wherein the parts or modules in the network architectures are identified using corresponding element codes, and connection lines between the parts or modules and different vehicle buses are identified using different colors; the parts or modules in the signal flow architectures are identified using corresponding element codes plus element pictures, and each of the signal flow directions between the parts or modules is identified using an arrow and a signal flow sequence number.

6 . A method for displaying vehicle system illustrations, wherein the method comprises:
acquiring a function system identifier of one of the function systems of the vehicle; acquiring, according to the function system identifier, a system illustration corresponding to the function system, wherein the system illustration is generated using the method comprising steps of: acquiring vehicle information of a vehicle, the vehicle information comprising vehicle brand information, vehicle model information, and vehicle configuration information; determining, according to the vehicle information, parts or modules included in function systems of the vehicle; acquiring, from a pre-established element database, elements corresponding to the parts or modules included in each function system, wherein the element database includes element information about a plurality of elements, each of the elements corresponds to one part or module, and the element information includes element codes and element pictures; acquiring connection relation information between the parts or modules included in the function systems and vehicle buses, and signal flow direction information between the parts or modules; and generating, according to the element information of the elements corresponding to the parts or modules included in the function systems, the connection relation information and the signal flow direction information, system illustrations corresponding to the function systems of the vehicle; acquiring a system illustration file corresponding to the function system according to the function system identifier; and associating the system illustration with the system illustration file for display.

7 . The method according to claim 6 , further comprising:
arranging, according to the function systems included in the vehicle, and parts or modules included in the function systems, corresponding system illustration files for the function systems of the vehicle, wherein the system illustration files include at least one of a functional illustration file, a part illustration file, a signal flow illustration file, and a case illustration file.

8 . (canceled)

9 . An electronic device, comprising a processor and a memory having stored thereon a computer program which, when executed by the processor, causes the processor to carry out the method comprising steps of:
