Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional active chassis systems for vehicles are optimized for a single tire temperature range or a compromise between cold and normal ranges, failing to provide optimal performance across the entire operating temperature range of high-performance tires, which affects traction capabilities and overall vehicle performance and safety.
Innovation Solution
A method and system that dynamically adjust active chassis systems using tire temperature data from sensors, allowing for real-time optimization of braking, power application, and control inputs to tires based on classified tire temperature states, ensuring optimal performance across varying temperatures and responding to aggressive driving habits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional active chassis systems are optimized for a single temperature range, then performance is improved in that specific range, but performance deteriorates in other temperature ranges
Solution Approach 1:
The system dynamically adjusts active chassis control parameters based on real-time tire temperature measurements. The controller continuously monitors tire temperature and modifies braking, power application, and control inputs according to the current temperature state, enabling the system to adapt to varying thermal conditions rather than being fixed for a single range.
Solution Approach 2:
The system changes operational parameters of the active chassis systems based on tire temperature. Different temperature ranges (cold, nominal, hot) trigger different parameter settings for braking force distribution, power application characteristics, and control sensitivity, allowing optimization across the entire operating temperature spectrum.
2Adaptability or versatility
If a compromise optimization is employed for two temperature ranges, then adequate performance is provided across ranges, but peak performance is lost in either range
Solution Approach 1:
The temperature operating range is segmented into distinct categories (cold, nominal, hot) with specific threshold values. Each segment has optimized control parameters tailored to that specific temperature condition, allowing the system to achieve peak performance in each range rather than using a single compromise setting for multiple ranges.
3Device complexity
If tire temperature is not monitored, then system complexity is reduced, but performance optimization is limited
Solution Approach 1:
The system replaces complex mechanical temperature sensing and adjustment mechanisms with electronic sensors and electronic control. Temperature sensors provide electronic signals to a controller that electronically adjusts chassis parameters, achieving precise temperature-based optimization with simpler, more reliable electronic components rather than mechanical systems.
