Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods do not provide a comprehensive solution for automatically or semi-automatically adjusting a vehicle's chassis to optimize handling based on road conditions, such as damage, hills, and depressions, which can lead to potential damage to the vehicle's underbody or roof.
Innovation Solution
A method utilizing a sensor system comprising acceleration sensors, cameras, and spring travel sensors to detect road conditions, transmitting data to a central server for analysis and consolidation, and providing real-time recommendations for chassis adjustments, including suspension, shock absorber, and stabilizer system parameters, with driver confirmation for semi-automatic acceptance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual chassis adjustment is used, then driver control is maintained, but response time to road conditions is delayed and optimization is reduced
Solution Approach 1:
The system performs preliminary detection of road conditions using sensors (acceleration sensors, cameras, spring travel sensors) and pre-calculates optimal chassis adjustments before the vehicle encounters the actual road irregularities. This allows the chassis to be proactively adjusted in advance, improving response time and preventing damage rather than reacting after damage occurs.
2Measurement precision
If comprehensive sensor systems are deployed, then road condition detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple different types of sensors (acceleration sensors, cameras, spring travel sensors) into an integrated sensor system that works together to detect road conditions. By merging these sensing capabilities, the system achieves comprehensive and accurate road condition detection while sharing processing and control infrastructure, thereby managing complexity through integration rather than separate independent systems.
Solution Approach 2:
The sensor system is designed to perform multiple functions: acceleration sensors detect both vehicle dynamics and road surface characteristics, cameras identify road markings and obstacles, and spring travel sensors measure suspension compression. This multi-functionality allows a single integrated system to gather comprehensive road condition data without requiring separate specialized sensors for each measurement type, reducing overall system complexity.
3Stability of the object's composition
If real-time chassis adjustment is implemented, then vehicle stability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuously adjusting the chassis, the system periodically detects road conditions using sensors and makes discrete adjustments only when road irregularities are detected. The adjustment is maintained until the next detection cycle confirms improved conditions or new irregularities are found. This periodic approach maintains vehicle stability during critical moments while minimizing energy consumption during normal driving conditions.

Function Achieved in This Case
Enables reliable and adaptive chassis adjustments to prevent damage from road irregularities, improving vehicle stability and safety across various road types and environments.
Implementation Method 1
The measuring principle of an acceleration sensor is based on the known relationship between acceleration and force. A mass that is subject to a certain acceleration reacts with an inertial force to the body that applies the acceleration to the mass.
Implementation Method 2
spring travel sensors connected to the chassis of the vehicle 10 and/or at least one wheel acceleration sensor and/or at least one wheel pressure sensor
