Active Suspension Control Using V2X Road Surface Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional suspension systems struggle to quickly respond to sudden changes in road surface conditions, especially at night or when relying on low-resolution camera images, and are influenced by the type of preceding vehicle's suspension, leading to inaccurate control.
Innovation Solution
A road surface detection apparatus using an inclinometer and ride height sensor provides road surface information via V2X communication to a subsequent mobility device, enabling proactive suspension control based on inclinations, heights, and positions, using V2X and V2V communication to transmit control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If camera-based road surface monitoring is used, then the system can detect road conditions in advance, but the measurement precision deteriorates when images have low resolution due to night driving
Solution Approach 1:
The patent replaces camera-based optical detection with sensor-based mechanical/physical detection. Specifically, it uses inclinometers to measure road surface inclination angles and ride height sensors to detect vertical displacement, providing precise quantitative measurements independent of lighting conditions and image resolution.
2Loss of information
If suspension control is based on preceding vehicle's driving state, then the system can utilize available information, but the reliability deteriorates due to variations in vehicle type and suspension configuration
Solution Approach 1:
The patent creates a standardized digital copy of road surface conditions through sensor measurements. By using inclinometers and ride height sensors to generate objective numerical data about road surface inclination and height changes, the system creates a universal information format that can be reliably transmitted and used by following vehicles regardless of the preceding vehicle's specific characteristics.
3Device complexity
If conventional suspension modules are used, then the device complexity remains low, but the speed of response to sudden road surface changes deteriorates
Solution Approach 1:
The patent implements preliminary action by having the preceding vehicle detect and transmit road surface condition information before the following vehicle encounters the same road features. The following vehicle receives this advance information and proactively adjusts its suspension parameters in preparation for upcoming road irregularities, enabling preemptive suspension control.
Solution Approach 2:
The patent establishes a feedback loop where road surface condition data is continuously collected by sensors, transmitted through V2X communication to following vehicles, and used to dynamically adjust suspension control parameters. This real-time information feedback enables the suspension system to respond quickly to changing road conditions.
