Description

Technical Field

[0001] This utility model patent relates to the field of vehicle body domain control technology, mainly to a vehicle body domain controller with face recognition function. Background Art

[0002] The concept of domain controller was first proposed by Tier 1 companies led by Bosch and Continental. It was created to solve the problems of information security and ECU bottlenecks. According to the functions of automotive electronic components, the entire vehicle is divided into power domain, chassis domain, body domain, autonomous driving domain and intelligent information domain. With the powerful computing power of the CPU, the distributed ECUs are unified, and the control functions are rapid and centralized.

[0003] However, in the process of body domain control, the body domain controller plays the main role. The existing body domain controller has a single structure and low control security, which is prone to corresponding safety accidents and difficult to ensure the safety of the car. In addition, a single virtual lock is difficult to meet the actual use requirements, resulting in inconvenient control. In this regard, we propose a car body domain controller with face recognition function. Utility Model Content
