Vehicle Control Device Manual Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems fail to provide drivers with a sense of unity during operation, as they automatically control vehicle stability without considering the driver's intentions.
Innovation Solution
A vehicle control device with an operation unit that allows drivers to manually control vehicle height, roll angle, and pitch angle through sensors and motors, enabling synchronized driver input and vehicle response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the vehicle is automatically controlled to maintain control stability, then the vehicle stability is improved, but the driver's sense of unity with the vehicle deteriorates
Solution Approach 1:
Instead of the controller automatically adjusting suspension height to maintain stability, the invention inverts the control flow by having the driver directly control suspension height through an operation unit. This inversion transforms the automatic stability control system into a manual control system that provides tactile feedback and sense of unity to the driver while still maintaining vehicle stability through coordinated control of multiple suspension units.
2Stability of the object's composition
If the spring constant of the air suspension unit is changed to increase roll rigidity, then the vehicle stability is improved, but the driver's sense of unity with the vehicle deteriorates
Solution Approach 1:
The invention applies dynamics by making the suspension system height adjustable in real-time based on driver input rather than fixed. The controller dynamically coordinates the height of multiple suspension units (front left, front right, rear left, rear right) according to the operation unit's position, enabling the vehicle to adapt its roll rigidity and stability characteristics during operation while maintaining driver engagement.
3Ease of operation
If the height of the vehicle is changed according to driver operation, then the driver's sense of unity with the vehicle is improved, but the device complexity increases
Solution Approach 1:
The operation unit serves multiple functions: it controls the height of suspension units, and through coordinated control of multiple suspension units, it also indirectly controls roll angle and pitch angle. This multi-functionality reduces the need for separate control mechanisms for each vehicle parameter, thereby limiting the increase in device complexity while achieving comprehensive vehicle dynamics control.
4Ease of operation
If the heights of right and left suspension units or front and rear suspension units are changed to change roll angle or pitch angle, then the driver's sense of unity with the vehicle is improved, but the device complexity increases
Solution Approach 1:
The invention merges the control of multiple suspension units under a single operation unit and controller. By coordinating the height adjustment of right and left suspension units or front and rear suspension units through one control system, it achieves roll angle and pitch angle control without requiring separate control mechanisms for each suspension unit, thereby limiting the increase in device complexity.

AI summary
A vehicle control device includes an operation unit operated by a driver; and a controller that causes a vehicle to turn according to a movement of the operation unit and causes a height of the vehicle to be changed. The controller causes the height of the vehicle to be changed according to an upward or downward movement of the operation unit.
