Active Suspension Pre-Adjustment for Road Disturbance Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active suspension systems in vehicles react too slowly to road conditions, causing discomfort to occupants due to finite response times, especially in bad road conditions.
Innovation Solution
A system and method that adaptively configures the suspension based on sensed driving parameters, vehicle cabin disturbances, and upcoming road segments to maintain desired comfort levels by selecting appropriate suspension configurations and adjusting actuator settings in real-time using machine learning-generated reference data structures and signatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active suspension uses onboard system to control vertical movement of wheels, then ride quality and car handling are improved, but response time is insufficient causing discomfort to occupants
Solution Approach 1:
The system uses sensors to detect road conditions ahead of time and pre-adjusts suspension parameters before the vehicle encounters the disturbance, transforming reactive suspension control into proactive control that anticipates upcoming road variations
Solution Approach 2:
The suspension system dynamically adjusts its characteristics in real-time based on detected road conditions, changing suspension firmness and damping properties adaptively rather than maintaining fixed settings
2Ease of operation
If adaptive suspension varies shock absorber firmness, then ride comfort is improved, but inability to anticipate road elements causes discomfort
Solution Approach 1:
The system performs preliminary detection of road elements using sensors positioned to detect upcoming disturbances, allowing the suspension to prepare and adjust before the vehicle actually encounters the road variation
Solution Approach 2:
The system continuously monitors road conditions through sensors and uses this feedback to dynamically adjust suspension parameters, creating a closed-loop control system that responds to real-time road variations
Data Source
AI summary
A method for configuring a configurable suspension, the method may include obtaining acquired sensed information that represent (a) one or more driving parameters of the vehicle, (b) one or more vehicle cabin disturbance parameters, (c) a configuration of a configurable suspension, and (d) a road segment that precedes the vehicle; selecting, out of multiple configurations of the configurable suspension, a selected configuration that one applied will attribute to obtain a desired human-in-vehicle comfort value; and triggering or requesting a setting of the configurable suspension to a configuration of the one or more configurations.
