Description

Technical Field

[0001] This utility model belongs to the field of domain controllers, and more specifically relates to an autonomous driving domain controller for automobiles. Background Technology

[0002] Currently, automotive autonomous driving domain controllers integrate multiple functional modules onto a single printed circuit board (PCB). They are specifically designed and manufactured based on the vehicle's functional requirements and performance. For example, video information acquisition is integrated onto a single control board according to design requirements, only accommodating a predetermined number of cameras. These domain controllers target a relatively narrow user base, lack versatility, and cannot adapt to the needs of multiple types of camera video acquisition. Once the domain controller design is finalized, if other video acquisition requirements arise, the next domain controller will require a complete redesign of the entire autonomous driving domain controller, necessitating overall controller design, drive circuit design, PCB board design, and controller testing. In the current fiercely competitive environment of emerging car manufacturers, shortening development, design, production, and testing time is crucial for enhancing market competitiveness. Utility Model Content

[0003] The technical problem this utility model aims to solve is the defects and shortcomings of the current mainstream vehicle host domain controllers: the structure of automotive domain controllers is basically a single unit, with the core processor unit directly soldered to the drive circuit board, making it impossible to replace or upgrade the hardware. The video acquisition circuit is also concentrated in the domain controller. Once the video acquisition software type needs to be changed or the camera needs to be upgraded, the entire domain controller needs to be replaced, which requires a lot of time and money. To solve the above problems, this utility model provides an autonomous driving domain controller that is adaptable to multiple types of video acquisition.

[0004] The objective of this utility model is achieved in the following manner:

[0005] An autonomous driving domain controller adaptable to multiple types of video acquisition is provided. The domain controller includes a core board, a controller board, and a video acquisition board. The video acquisition board is provided with multiple camera interfaces and a controller board connection interface. The output terminals of the multiple camera interfaces are connected to the controller board connection interface. The controller board is provided with a main control module, a video acquisition board interface, and a core board interface. The controller board connection interface is connected to the video acquisition board interface, the video acquisition board interface is connected to the main control module, and the main control module is connected to the core processor module on the core board through the core board interface.

[0006] The controller board interface and the video acquisition board interface are board-to-board connectors that plug into each other.

[0007] The controller board and video acquisition board are also equipped with a power interface, which is a power plug-in interface.

[0008] The core board interface uses a 699-pin MOLEX high-speed connector.

[0009] The controller board is located in the middle, the core processor module is plugged into the corresponding controller board interface and is located below the controller board, and the video acquisition board is plugged into the corresponding controller board interface and is located above the controller board.

[0010] The beneficial effects of this invention are as follows: By reserving a video acquisition board interface on the core control board, a video acquisition board can be connected. The hardware of the video acquisition board can be modified and optimized to adapt to the new requirements and performance of video acquisition in autonomous driving. This invention solves the problems of existing automotive autonomous driving domain controllers being unable to replace or upgrade video acquisition hardware after finalization, and also suffers from low adaptability.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same technical meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0015] like Figure 1-2 As shown, an autonomous driving domain controller adaptable to multiple types of video acquisition is disclosed. The domain controller includes a core board, a controller board, and a video acquisition board. The video acquisition board is provided with multiple camera interfaces and a controller board connection interface. The output terminals of the multiple camera interfaces are connected to the controller board connection interface. The controller board is provided with a main control module, a video acquisition board interface, and a core board interface. The controller board connection interface is connected to the video acquisition board interface, the video acquisition board interface is connected to the main control module, and the main control module is connected to the core processor module on the core board through the core board interface.

[0016] The multiple camera interfaces are used to connect cameras. The video capture board can be expanded to connect various types of camera hardware devices, such as cameras using the FPD-link and GMSL standard protocols, and the number of camera interfaces can be increased according to the video capture application requirements.

[0017] The controller board interface and the video acquisition board interface are board-to-board connectors that plug into each other.

[0018] The controller board and video acquisition board are also equipped with a power interface, which is a power plug-in interface.

[0019] The core board interface uses a 699-pin MOLEX high-speed connector.

[0020] The controller board is located in the middle, the core processor module is plugged into the corresponding controller board interface and is located below the controller board, and the video acquisition board is plugged into the corresponding controller board interface and is located above the controller board.

[0021] Once the docking is complete, power is supplied to the autonomous driving domain controller, enabling autonomous driving functions such as video information acquisition, path planning, and control strategies.

[0022] To meet the requirements of multi-channel video acquisition, and based on the current capabilities of mainstream data processing chips in the automotive industry, this invention adopts an architecture of a controller board + video acquisition board. The main control module of the controller board is responsible for processing large volumes of sensor signals and vehicle path planning, while the video acquisition board is responsible for acquiring visual data.

[0023] The controller board serves as the middle layer, the core processor module of the core board as the upper layer, and the video capture board as the lower layer. The controller board provides power and interfaces for the core processor module and camera module. The core processor module provides data processing and vehicle path planning for autonomous driving, while the camera interface acquires image data to provide external information for autonomous driving.

[0024] By reserving a video capture board interface on the core controller board, a video capture board can be connected. The hardware of the video capture board can be modified and optimized to adapt to the new requirements and performance demands of video capture in autonomous driving. This utility model solves the problems of existing automotive autonomous driving domain controllers, such as the inability to replace or upgrade video capture hardware after finalization, and their low adaptability.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that those skilled in the art can make several changes and improvements without departing from the overall concept of the present utility model, and these should also be considered within the protection scope of the present utility model.
