Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of universal joints in vehicle steering systems introduces non-linearity, leading to deviations in steering response and torque feedback due to geometric constraints, affecting the intended steering experience.
Innovation Solution
The implementation of a non-uniformity manager that uses sensors to measure and map the current position of the steering column and wheel, applying offsets to adjust the steering wheel to a nominal position, compensating for clear vision errors and non-uniformities through an active steering system.

1Volume of moving object
If universal joints are used to transmit torque between non-collinear axes, then space limitations in the vehicle are accommodated, but non-linearity is introduced causing deviations in steering response and torque feedback
Solution Approach 1:
The system dynamically changes the steering angle parameter by applying a compensation angle that is calculated based on the steering column position and universal joint geometry. This parameter change corrects the non-linear steering response caused by the universal joints, ensuring accurate steering feedback while maintaining the space-saving non-collinear axis configuration
Solution Approach 2:
The patent replaces pure mechanical steering transmission with a hybrid system that incorporates electronic sensors and computational algorithms. The sensors detect steering column position and universal joint angles, and a processor calculates compensation angles to correct the mechanical non-linearity, substituting mechanical precision requirements with electronic measurement and computational correction
2Ease of operation
If the steering column position is adjusted, then driver comfort and ergonomics are improved, but clear vision errors and non-uniformity in steering response increase
Solution Approach 1:
The system dynamically adapts the steering angle compensation based on the real-time position of the steering column. As the steering column position changes with driver adjustments, the sensors continuously monitor the position and the processor dynamically recalculates the compensation angle to maintain accurate steering response across all column positions, making the system adaptive rather than static
Solution Approach 2:
The system implements a feedback loop where sensors continuously measure the steering column position and universal joint angles, the processor calculates the appropriate compensation angle based on this feedback, and the compensation is applied to correct the steering response. This closed-loop feedback ensures that steering accuracy is maintained regardless of steering column position adjustments
