Roll Locking ECU with Dual Processors for Safe Vehicle Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing three- or four-wheeled rolling motor vehicles face safety challenges in the electronic control of roll locking systems, particularly in ensuring safe activation and deactivation based on speed and parking states, requiring robust and high-performance electronic components and complex algorithms.
Innovation Solution
A three- or four-wheeled rolling motor vehicle equipped with a controllable roll locking system and an electronic control unit comprising dual processing units to ensure high safety and reliability, where a first processing unit determines operational states based on speed and parking conditions, and a second processing unit validates these states through integrity checks and safety conditions before allowing the roll locking system to engage or disengage.

Engineering Contradiction Analysis
1Reliability
If a single processing unit is used to control the roll locking system, then the device complexity is reduced, but the reliability and safety of the control system deteriorates
Solution Approach 1:
The electronic control unit is segmented into two independent processing units, each capable of independently determining and validating operational states. This segmentation allows the system to divide the control function into separate modules that can cross-validate each other, thereby improving reliability without creating a single point of failure.
Solution Approach 2:
The second processing unit acts as an intermediary validator that receives operational state determinations from the first processing unit and performs integrity checks before final execution. This intermediary layer provides an additional safety mechanism that validates control commands without requiring complete system redesign.
2Reliability
If dual processing units with integrity checks are implemented, then the safety and reliability of the roll locking system is enhanced, but the device complexity increases
Solution Approach 1:
The control system is divided into two distinct processing units with clearly defined roles: one for determining operational states and another for validating those states through integrity checks. This functional segmentation enables enhanced safety while maintaining manageable complexity through modular design.
Solution Approach 2:
The second processing unit provides feedback validation to the first processing unit by performing integrity checks on determined operational states. This feedback mechanism ensures that control commands are verified before execution, creating a self-correcting system that enhances reliability through continuous validation.
