Vehicle Air Suspension Control System Using GPS Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air suspension systems lack an efficient automatic adjustment mechanism that can adapt to changing conditions and driver preferences, often resulting in potential damage from inadequate ride height adjustments.
Innovation Solution
A system utilizing a central processing unit coupled with GPS, air pressure sensors, and user interfaces to automatically adjust ride height based on preset location data and vehicle speed, allowing for customizable and adaptive ride height adjustments through a touch-screen interface or other input methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic ride height adjustment based on GPS location and vehicle speed is implemented, then vehicle safety and damage prevention are improved, but system complexity increases
Solution Approach 1:
The patent combines multiple functions into a single control system: GPS location monitoring, vehicle speed sensing, automatic ride height calculation, and air spring adjustment all occur through one integrated controller. This merging of navigation, sensing, and suspension control functions resolves the contradiction by achieving comprehensive vehicle protection while consolidating system complexity into a unified architecture.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring GPS location and vehicle speed to predict upcoming conditions (such as speed bumps or steep inclines) before they occur. The controller proactively adjusts ride height in advance based on pre-stored location data and real-time speed information, preventing damage before it happens rather than reacting after damage occurs.
2Measurement precision
If multiple sensors and GPS integration are used for automatic adjustment, then adjustment accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The control system is designed with multi-functionality, serving as a universal platform that handles GPS signal processing, vehicle speed measurement, ride height calculation, and air spring control. This universal controller can process multiple types of inputs (GPS coordinates, speed signals, location data) through a single integrated unit, reducing the need for separate dedicated components and thereby lowering manufacturing costs while maintaining high measurement precision.
3Loss of time
If continuous monitoring of vehicle speed and location is performed, then ride height adjustment timeliness is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic monitoring and adjustment cycles rather than continuous operation. The controller periodically checks GPS location data and vehicle speed signals, compares current position with pre-stored location information, and triggers ride height adjustments only when approaching specific geographic coordinates or speed thresholds. This periodic action pattern maintains timely response to critical conditions while significantly reducing energy consumption compared to continuous monitoring.
