Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steering systems face a conflict between needing to withstand varying loads while maintaining cost-efficiency, as they are often designed to handle extreme loads, which increases manufacturing costs.
Innovation Solution
A method for controlling a steering system that detects and mitigates loads exceeding a variable load threshold based on influencing parameters, allowing the system to operate within its load capacity without needing to be mechanically robust for extreme conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the steering system is designed to withstand extreme loads, then the reliability and stability are improved, but the manufacturing cost increases
Solution Approach 1:
The patent implements dynamic load threshold adjustment based on operational conditions. The control unit adapts the load threshold according to parameters such as vehicle speed, steering angle, and road conditions, allowing the steering system to operate with reduced mechanical robustness while maintaining reliability through active control. This resolves the contradiction by replacing static over-engineering with dynamic adaptation.
Solution Approach 2:
The patent changes the parameter of load threshold from a fixed mechanical design constraint to a variable control parameter. By adjusting the load threshold based on influencing parameters (vehicle speed, steering angle, etc.), the system achieves reliable operation without requiring mechanical design for extreme loads, thereby reducing manufacturing costs while maintaining safety.
2Stability of the object's composition
If the steering system is mechanically dimensioned for extreme loads, then the stability is improved, but the system complexity increases
Solution Approach 1:
The patent replaces mechanical robustness with electronic control. Instead of designing a mechanically complex system capable of withstanding extreme loads, the invention uses a control unit that dynamically adjusts load thresholds and triggers mitigation measures when thresholds are exceeded. This substitution of mechanical design with electronic control reduces system complexity while maintaining stability.
3Reliability
If the load threshold is increased to handle extreme use cases, then the reliability is improved, but the resource efficiency decreases
Solution Approach 1:
The patent implements dynamic load threshold adjustment based on operational conditions. The control unit adapts the load threshold according to parameters such as vehicle speed, steering angle, and road conditions, allowing the steering system to operate with reduced mechanical robustness while maintaining reliability through active control. This resolves the contradiction by replacing static over-engineering with dynamic adaptation.

AI summary
The disclosure relates to a method for controlling a steering system for a vehicle. The method comprises obtaining (S310) first data indicative of a load. The method further comprises obtaining (S320) second data indicative of at least one parameter influencing the load or influencing a load capacity of the steering system. The method further comprises obtaining (S330) third data indicative of a load threshold. The load threshold is based on the second data. The method still further comprises comparing (S340) the first data and the third data, and causing a load mitigation measure if the first data and the third data indicate that the load equals or exceeds the load threshold. Furthermore, a data processing apparatus, a vehicle, a computer program, a computer-readable storage medium and a use of a load mitigation measure and/or data are presented.
