Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-performance sports vehicles face compromises in driver comfort, tire wear, and fuel consumption due to traditional mechanical configurations that are not easily adjustable, leading to suboptimal performance in various driving conditions.
Innovation Solution
A system that collects tire temperature and wheel camber data, along with location information from sensors, processes this data to determine optimal wheel camber settings for specific road segments, which are then stored and used to adjust the vehicle's camber settings in real-time, allowing for dynamic adjustments based on current conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mechanical configurations are used for high-performance sports vehicles, then vehicle grip and cornering performance are improved, but driver comfort deteriorates and tire wear increases
Solution Approach 1:
The patent implements dynamic wheel camber adjustments that automatically adapt to different driving conditions and road segments. The system transitions from static mechanical configurations to dynamically adjustable settings, optimizing the balance between performance and comfort based on real-time conditions without requiring manual driver intervention.
Solution Approach 2:
The system changes wheel camber parameters dynamically based on location data, tire temperature, and driving conditions. By adjusting camber angles as a variable parameter rather than a fixed mechanical setting, the system achieves optimal performance across diverse conditions while maintaining driver comfort and reducing tire wear.
2Reliability
If traditional mechanical configurations are used for high-performance sports vehicles, then vehicle grip and cornering performance are improved, but tire wear increases
Solution Approach 1:
The system dynamically adjusts wheel camber settings based on real-time conditions including tire temperature and location data. This prevents excessive camber angles that would cause rapid tire wear while maintaining adequate grip and cornering performance, thereby extending tire lifespan without sacrificing vehicle performance.
Solution Approach 2:
The system incorporates feedback from tire temperature sensors and location data to continuously optimize wheel camber settings. This feedback mechanism ensures that camber angles are adjusted to prevent overheating and excessive wear of tires while maintaining the necessary grip and cornering performance for high-performance driving.
3Adaptability or versatility
If wheel camber settings are made adjustable to adapt to different driving conditions, then vehicle performance is improved, but device complexity increases
Solution Approach 1:
The system automatically determines and adjusts optimal wheel camber settings based on location data and sensor readings without requiring manual driver input. The vehicle essentially serves itself by autonomously optimizing performance parameters, which simplifies the user interface while maintaining high adaptability to different driving conditions.
Solution Approach 2:
The system integrates multiple functions into a single unified approach: location-based camber optimization, tire temperature monitoring, and performance adjustment all work together through one system. This multi-functionality reduces overall complexity compared to separate systems for each function while achieving comprehensive performance adaptability.
Data Source
AI summary
An approach is provided for location-aware wheel camber settings. The approach involves, for example, collecting tire temperature data, wheel camber data, and location data from one or more sensors of a plurality of vehicles. The approach also involves processing the tire temperature data, wheel camber data, and location data to determine a target wheel camber for a road segment indicated by the location data. The target wheel camber is determined from one or more observed wheel cambers indicated in the wheel camber data. The target wheel camber is also associated with a target tire temperature indicated in the tire temperature data. The approach further involves storing the target wheel camber as an attribute of map data associated with the road segment.
