Air Suspension Compressor Control for Counter Roll Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing suspension device for vehicle height adjustment in counter roll control requires alternate adjustment of air suspensions between front and rear wheels, leading to responsiveness issues during counter roll control.
Innovation Solution
A suspension device with a compressor system that allows independent counter roll generation by transferring compressed air between left and right air suspensions of both front and rear wheels, enabling concurrent vehicle height adjustment and improving responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air suspensions of front and rear wheels are alternately adjusted to prevent pressure escape, then the system maintains pressure control, but the responsiveness during counter roll control deteriorates
Solution Approach 1:
The system divides the air suspension control into independent front and rear wheel groups, allowing simultaneous adjustment of front wheels and rear wheels rather than alternating between them. This segmentation enables parallel operation of compressors for front and rear air suspensions, improving responsiveness while maintaining pressure control through independent regulation of each group.
Solution Approach 2:
The system merges the control of front and rear air suspensions into a coordinated simultaneous adjustment process. By combining the operation of multiple compressors to work together on both front and rear air suspensions at the same time, the system achieves faster counter roll response while maintaining reliable pressure control through unified management.
2Stability of the object's composition
If compressed air is transferred between front wheel air suspensions and rear wheel air suspensions, then pressure equalization is achieved, but the counter roll control responsiveness deteriorates due to alternate adjustment requirement
Solution Approach 1:
The system segments the air transfer operation into two independent simultaneous processes: one transferring air between front wheel air suspensions and another transferring air between rear wheel air suspensions. This allows pressure equalization to occur in both front and rear sections simultaneously, eliminating the alternate adjustment requirement and improving counter roll responsiveness.
Solution Approach 2:
The system maintains continuous useful action by performing air transfer operations in both front and rear wheel sections simultaneously rather than alternately. This continuous parallel operation ensures that pressure equalization occurs throughout the entire suspension system at the same time, maximizing responsiveness during counter roll control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enhances responsiveness during counter roll control by allowing simultaneous and independent adjustments of air suspensions, reducing the time required for vehicle height adjustments and improving the vehicle's stability during turns.
Implementation Method 1
a compressor configured to supply compressed air to the front wheel left air suspension, the front wheel right air suspension, the rear wheel left air suspension, and the rear wheel-side right air suspension
Implementation Method 2
The compressor is used to transfer compressed air between the front wheel-side left and right air suspensions... so that, when a vehicle's driving situation is a rolling state, the front wheel-side left and right air suspensions and the rear wheel-side left and right air suspensions independently generate counter rolls
Implementation Method 3
configured to adjust vehicle height by controlling the supply and exhaust of compressed air to and from an air suspension of each wheel

AI summary
When a vehicle's driving situation is a rolling state, a compressor is used to transfer compressed air between left and right air suspensions of front wheels, and a compressor is used to transfer compressed air between left and right air suspensions of rear wheels. The air suspensions of the left and right front wheels and the air suspensions of the left and rear wheels thus independently generate counter rolls. This makes it possible to concurrently perform vehicle height adjustment of the air suspensions of the left and right front wheels and vehicle height adjustment of the air suspensions of the left and right rear wheels, which improves responsiveness in counter roll control.
