Abstract

A system, automobile, and method for implementing an electronic control function of an automobile. The system includes a first vehicle integration unit (VIU), an automobile control unit, and a plurality of automobile parts. The automobile control unit includes a first domain controller (DC) or a central computing platform (CCP). The automobile control unit is configured to send first control information to the first VIU. The first VIU is configured to control the plurality of automobile parts based on the first control information. In embodiments of this application, the first VIU controls the plurality of automobile parts.

First claim

What is claimed is:

1. A system for implementing an automobile electronic control function on an automobile, wherein the system comprises:
a plurality of automobile parts in a first automobile part set and located on the automobile, wherein the plurality of automobile parts comprises a first automobile part that is in a first functional domain for performing a first operation and a second automobile part that is in a second functional domain for performing a second operation that is different from the first operation;
a first vehicle integration unit (VIU) connected to the plurality of automobile parts and configured to provide data processing function for the first automobile part set;
a first domain controller (DC) of the first functional domain connected to the first VIU, wherein the first DC is configured to send first control information to the first VIU for controlling an operation of the first automobile part;
a second DC of the second functional domain connected to the first VIU, wherein the second DC is configured to send second control information to the first VIU for controlling an operation of the second automobile part, wherein the first VIU is configured to control the first automobile part to perform the first operation based on the first control information and control the second automobile part to perform the second operation based on the second control information;
a third automobile part set; and
a third VIU connected to the third automobile part set, wherein the third VIU is configured to provide a data processing function for the third automobile part set, and wherein the first VIU is further configured to provide the data processing function for the third automobile part set.

2. The system according to claim 1 , further comprising a plurality of VIUs including the first VIU.

3. The system according to claim 2 , wherein the plurality of VIUs forms a ring communications network.

4. The system according to claim 1 , further comprising a plurality of VIUs including the first VIU, wherein any two different VIUs in the plurality of VIUs have a communication connection with one another.

5. The system according to claim 1 , wherein the plurality of automobile parts is in a first automobile part set, wherein the first VIU is configured to control the first automobile part set, wherein the system further comprises:
a second automobile part set; and
a second VIU connected to the second automobile part set, wherein the second VIU is configured to control the second automobile part set, and
wherein the first VIU is further configured to:
receive third control information for controlling a third automobile part in the second automobile part set when the second VIU fails; and
control the third automobile part in the second automobile part set based on the third control information.

6. The system according to claim 1 , wherein the first DC is an intelligent driving domain controller of the automobile, and wherein the second DC comprises a chassis domain controller of the automobile.

7. The system according to claim 1 ,
wherein the first VIU is further configured to:
obtain first data from the first automobile part; and
send the first data to the first DC.

8. The system according to claim 7 , wherein the first VIU is further configured to:
obtain second data from the first automobile part; and
process the second data to obtain the first data, wherein processing the second data comprises one or more of: converting a protocol of the second data, encapsulating the second data according to a transport protocol, or converting a data format of the second data.

9. The system according to claim 1 , wherein the first DC and the second DC are selected from DCs comprising at least one of a self-driving domain controller, a cockpit domain controller (CDC), or a vehicle domain controller (VDC).

10. The system according to claim 1 , wherein the first VIU comprises one or more of an electronic control function, a gateway function, or a data processing function across automobile parts.

11. The system according to claim 1 , wherein the first VIU is configured to implement an electronic control function provided by an electronic control unit (ECU) in some or all of the plurality of automobile parts without ECUs in the some or all of the plurality of automobile parts.

12. A method for implementing an electronic control function of an automobile, wherein the automobile comprises a first vehicle integration unit (VIU) and a plurality of automobile parts, wherein the plurality of automobile parts is in a first automobile part set, and wherein the method comprises:
receiving, by the first VIU, first control information from a first domain controller (DC) of a first functional domain of the automobile and second control information from a second DC of a second function domain of the automobile;
controlling, by the first VIU, a first automobile part based on the first control information to perform a first operation;
controlling, by the first VIU, a second automobile part based on the second control information to perform a second operation that is different from the first operation, wherein the plurality of automobile parts comprises the first automobile part that is in the first functional domain and the second automobile part that is in the second functional domain;
providing, by the first VIU, data processing function for the first automobile part set; and
providing, by a third VIU connected to a third automobile part set, a data processing function for the third automobile part set, wherein the first VIU is configured to provide the data processing function for the third automobile part set.

13. The method according to claim 12 , further comprising:
obtaining, by the first VIU, first data from the first automobile part; and
sending, by the first VIU, the first data to the first DC.

14. The method according to claim 12 , wherein the automobile comprises a plurality of VIUs including the first VIU.

15. The method according to claim 14 , wherein the plurality of VIUs forms a ring communications network.

16. The method according to claim 12 , wherein the automobile comprises a plurality of VIUs including the first VIU, and wherein any two different VIUs in the plurality of VIUs have a communication connection with one another.

17. The method according to claim 12 , wherein the first DC and the second DC are selected from DCs comprising at least one of a self-driving domain controller, a cockpit domain controller (CDC), or a vehicle domain controller (VDC).

18. The method according to claim 12 , wherein the first VIU comprises one or more of an electronic control function, a gateway function, or a data processing function across automobile parts.
