Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive-by-wire chassis systems in intelligent traffic environments struggle to realize ideal driving through driver operation intentions and environment information, as they lack the ability to correct driver operations in real-time based on traffic conditions, leading to potential safety hazards.
Innovation Solution
A cyber-physical system comprising a system-level CPS, unit-level CPS, and SoS-level CPS, which includes a driver input module, basic control module, environment perception module, and execution module, that processes sensor data to formulate optimal traveling strategies and correct driver inputs through a supervision platform and big data analysis, ensuring safe and efficient vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver operation intention is used to control the vehicle, then the driver's decision-making autonomy is maintained, but driving safety is compromised due to human limitations and errors
Solution Approach 1:
The system implements real-time feedback by continuously monitoring driver operations through sensors, comparing them against optimal trajectories generated by the supervision platform, and providing corrective feedback to adjust driver behavior. This closed-loop feedback mechanism ensures safety while preserving driver autonomy by gently guiding rather than forcibly overriding driver decisions.
Solution Approach 2:
The supervision platform acts as an intermediary between the driver and the vehicle execution systems. It processes driver intentions, combines them with environmental perception data, and generates optimized control commands that balance driver autonomy with safety requirements, rather than directly controlling the vehicle or completely overriding the driver.
2Manufacturing precision
If a complex mechanical or hydraulic system is used for chassis control, then execution precision is improved, but system complexity and maintenance difficulty increase
Solution Approach 1:
The system replaces complex mechanical and hydraulic transmission components with electronic sensors, controllers, and direct-actuation mechanisms. The drive-by-wire architecture uses electronic signals to directly control execution mechanisms, eliminating the need for complex mechanical linkages and hydraulic systems while maintaining or improving control precision.
3Reliability
If real-time driver operation correction is implemented, then driving safety is improved, but system response time and processing complexity increase
Solution Approach 1:
The supervision platform pre-generates optimal traveling strategies and trajectories based on environmental perception and historical data before driver operations are executed. This preliminary preparation allows the system to provide immediate corrective feedback when driver operations deviate from the optimal path, reducing response time while maintaining comprehensive safety monitoring.
