Tipper Vehicle Stability Control via Alignment Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tipper vehicles face stability issues during operational tipping processes, particularly when the angle between the longitudinal axes of the tractor and semi-trailer exceeds a critical value, leading to a heightened risk of tipping over, even on horizontal terrain, due to the shifting center of gravity and lateral inclinations.
Innovation Solution
A control device is integrated with alignment and lateral inclination sensors to limit or prevent the tipping process by emitting warning signals and restricting the tipping angle based on detected angles and inclinations, ensuring the vehicle does not exceed safe operational limits, and can be easily adapted into existing vehicles equipped with EBS and RSS systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tipper body is moved to the raised tipping position during operational tipping, then the tipping function is achieved, but the vehicle stability deteriorates due to center of gravity shifting and lateral inclination
Solution Approach 1:
The control device checks the alignment sensor data before allowing the tipping operation to proceed. By performing the stability assessment in advance (before tipping), the system prevents unstable conditions from developing while still allowing normal tipping operations when conditions are safe, thus resolving the contradiction between operational ease and stability.
Solution Approach 2:
The alignment sensor continuously monitors the angle between tractor and semi-trailer longitudinal axes and provides real-time feedback to the control device. This feedback mechanism allows the system to dynamically adjust tipping permissions based on current alignment conditions, ensuring stability is maintained while allowing tipping operations when safe.
2Reliability
If the angle between longitudinal axes of tractor and semi-trailer exceeds critical value, then the tipping risk increases, but limiting the tipping angle restricts operational functionality
Solution Approach 1:
The system dynamically adjusts the maximum permissible tipping angle based on real-time alignment conditions. When the angle between longitudinal axes is within safe limits, full tipping range is permitted. When alignment deviates beyond critical values, the maximum tipping angle is reduced or tipping is prevented entirely. This dynamic adjustment resolves the contradiction by adapting operational limits to current conditions.
3Reliability
If alignment sensor arrangement is integrated with control device, then safety is enhanced through real-time monitoring, but device complexity increases
Solution Approach 1:
The control device is designed to perform multiple functions: it controls the tipping mechanism operation, processes alignment sensor data, determines stability conditions, and manages warning signals. By making the control device multi-functional rather than adding separate dedicated systems for each function, the patent enhances safety monitoring while minimizing the increase in overall system complexity.
