Autonomous Driving Edge Node Delegation for Faster State Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems face inefficiencies due to independent vehicle functions that do not share data, leading to increased costs and service execution delays, particularly in centralized decision-making architectures where data processing and control instructions are layered, resulting in prolonged response times.
Innovation Solution
An autonomous driving system where sensor data is processed by edge nodes directly connected to the sensors, enabling these nodes to make perception decisions, with a central node delegating state decision functions to these edge nodes, reducing service execution delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If various functions of the vehicle develop independent of each other with separate sensor systems, then each function can operate autonomously, but the overall cost of the vehicle increases
Solution Approach 1:
The patent implements a unified sensor system that serves multiple vehicle functions simultaneously. The sensor system collects data that is processed by both the surround view system and the emergency braking assistive system, allowing one sensor system to perform multiple functions. This eliminates the need for separate sensor systems for each function, thereby reducing overall costs while maintaining functional independence through software-level processing.
2Adaptability or versatility
If various functions of the vehicle are handled in a centralized manner with a central node processing all data, then system integration is improved, but service execution delay increases
Solution Approach 1:
The patent divides the centralized processing architecture into distributed processing units. Each function (surround view system, emergency braking assistive system) has its own processing unit that can independently process sensor data. This segmentation allows parallel processing of different functions, reducing service execution delay while maintaining system integration through a unified sensor interface and coordinated control.
3Extent of automation
If sensor data is processed by a central node through layered delegation, then centralized control is maintained, but response time is prolonged
Solution Approach 1:
The patent implements preliminary processing of sensor data at the sensor level and at intermediate processing units before data reaches the central node. Edge computing capabilities are deployed to perform initial data filtering, feature extraction, and preliminary analysis close to the sensor source. This preliminary action reduces the volume and complexity of data that needs to be transmitted to and processed by the central node, thereby maintaining centralized control while significantly improving response time.

AI summary
An autonomous driving system includes a plurality of sensor combinations and a plurality of edge nodes, each of the plurality of sensor combinations includes at least one sensor; the plurality of edge nodes are in a one-to-one correspondence with the plurality of sensor combinations; and a first edge node in the plurality of edge nodes is configured to determine first perception information of a vehicle based on data collected by a first sensor combination corresponding to the first edge node. A central node is connected to the plurality of edge nodes. The central node is configured to delegate a first state decision function to the first edge node so that the first edge node determines that the vehicle enters a first state or determines a first driving policy of the vehicle in the first state by executing the first state decision function.
