Redundant Vehicle Perception Isolation on a Shared ECU
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The utilization efficiency of hardware resources is limited in redundant perception systems for autonomous and assisted driving due to the use of multiple separate electronic control units (ECUs), which can lead to reduced flexibility in software deployment and increased risk of malfunction.
Innovation Solution
Implementing software and/or hardware isolation between perception applications in two functional clusters, allowing each cluster to provide a minimum perception result, ensuring redundancy and enabling the use of shared hardware resources within a single ECU or similar architecture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate ECUs are used to construct a redundant perception system, then reliability is improved, but hardware resource utilization efficiency deteriorates
Solution Approach 1:
The patent merges multiple perception applications into a single ECU by implementing virtualization technology. Different perception applications are deployed as virtual machines or containers on the same physical hardware platform, allowing multiple isolated perception systems to coexist and share hardware resources efficiently while maintaining redundant perception capabilities
Solution Approach 2:
The patent creates a universal ECU platform that can host multiple different perception applications simultaneously. The virtualized environment enables a single ECU to perform multiple perception functions (e.g., object detection, lane detection, traffic sign recognition) that traditionally required separate dedicated ECUs, improving hardware utilization while maintaining system reliability
2Reliability
If multiple separate ECUs are used to construct a redundant perception system, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple perception ECUs into a single physical ECU through virtualization. Instead of integrating multiple separate physical devices with their own power supplies, communication interfaces, and mounting structures, the system consolidates them into one device with virtualized software environments, thereby reducing overall system complexity while preserving redundancy
Solution Approach 2:
The patent creates virtual copies of perception processing environments within a single ECU. Rather than physically duplicating entire ECU systems, the invention uses software-based virtualization to create isolated virtual instances that mimic separate ECU behavior, reducing hardware complexity while maintaining functional redundancy

AI summary
Embodiments of the present disclosure disclose a redundant perception method and apparatus, an electronic device, and a storage medium. The method includes: determining a first perception result based on a first perception application in a first perception functional cluster, where the first perception result includes a first minimum perception result, and the first minimum perception result is a perception result within a first preset minimum viewing-angle range; and determining a second perception result based on a second perception application in a second perception functional cluster, where the second perception result includes at least a second minimum perception result, software isolation and/or hardware isolation are implemented between the first perception application in the first perception functional cluster and at least a target second perception application, and the target second perception application represents a second perception application, for acquiring the second minimum perception result, in the second perception functional cluster.
