Vehicle Control Device for Suppressing Side Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to effectively suppress vibrations in the side direction, leading to degraded ride comfort during vehicle travel.
Innovation Solution
A vehicle control device that includes an operation condition detecting means, a suspension geometry adjusting means, and a control means to adjust the suspension geometry and steering gear ratio based on detected conditions, thereby canceling out forces applied to the vehicle body and tire, reducing side vibrations.

If the suspension geometry is adjusted to cancel side direction forces, then the side vibration is suppressed, but the system complexity increases
Solution Approach 1:
The suspension geometry adjusting means serves multiple functions: it adjusts the suspension geometry to cancel side direction forces, suppresses vibrations in all directions, and can adapt to different vehicle loads and road conditions. This multi-functionality justifies the added complexity by providing comprehensive vibration suppression that single-function systems cannot achieve
Solution Approach 2:
The control means automatically detects vehicle operating conditions and autonomously adjusts the suspension geometry to optimal settings without requiring manual intervention. The system self-regulates to maintain force cancellation across varying conditions, reducing the need for complex manual adjustment mechanisms
