Multi-Point Vehicle Leveling with 6-Axis Sensor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle leveling systems for large structures like recreational vehicles rely on user-actuated or semi-automatic controls, which lack efficient automatic adjustment mechanisms for precise leveling across multiple axes, leading to instability and uneven attitudes.
Innovation Solution
A multi-point leveling system utilizing a 6-axis digital sensor and controller to adjust the attitude of structures by actuating leveling jacks and stabilizers, providing automatic and semi-automatic modes for precise leveling across lateral pitch and longitudinal roll axes, with integrated security features and adaptive filtering for optimal sensor data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user-actuated or semi-automatic leveling controls are used, then the system is simpler to operate, but the leveling precision and automatic adjustment capability deteriorate
Solution Approach 1:
The leveling system automatically adjusts the vehicle attitude using sensor feedback and controller actuation of jacks and stabilizers, eliminating the need for manual user intervention while achieving precise leveling across multiple axes
Solution Approach 2:
The system uses 6-axis digital sensors to continuously monitor vehicle pitch and roll, providing real-time feedback to the controller which automatically adjusts the leveling jacks and stabilizers to maintain precise horizontal orientation
2Stability of the object's composition
If multi-point stabilizing systems are deployed, then the structure stability improves, but the device complexity increases
Solution Approach 1:
The stabilizing function is divided into multiple independent zones (first leveling zone with jack, second and third leveling zones with stabilizers) that can be controlled separately or simultaneously, allowing progressive stabilization while managing system complexity through modular control
Solution Approach 2:
The user interface is designed to control multiple leveling zones through unified switches that can operate individual jacks or pairs of stabilizers simultaneously, providing multiple stabilization modes through a single control system
3Productivity
If automatic leveling control is implemented, then the productivity of leveling operation improves, but the device complexity increases
Solution Approach 1:
The system automatically sequences the deployment of leveling components, first actuating the jack in the first leveling zone to establish initial contact, then progressively deploying stabilizers in the second and third zones based on sensed attitude requirements
Solution Approach 2:
Manual mechanical leveling operations are replaced with an automated electromechanical system using digital sensors, electronic controllers, and motorized jacks and stabilizers to achieve rapid automatic leveling

AI summary
Aspects herein relate to using a three or more points to control the angular orientation of a structure via three or more jacks, and then stabilizing the structure via one or more stabilizers. In some aspects, the foregoing structure may include, for example, a motor home, recreational vehicle, travel trailer or fifth wheel trailer.
