Turning Radius Control With Predicted Path for Long-Wheelbase Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles with a long wheelbase compared to their overall length face challenges in turning radius, leading to discomfort during operations like parking or U-turns, as conventional methods of improving turning performance through driving force distribution are often performed without driver knowledge.
Innovation Solution
A vehicle driving information providing method and system that operates in a turning radius control mode by determining parking or U-turn situations and differentially distributing driving force to each wheel based on a predetermined configuration mode, generating and outputting an expected driving path.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a long wheelbase is used compared to the overall length, then riding comfort and straight driving stability are improved, but turning radius increases causing discomfort in vehicle operation
Solution Approach 1:
The system changes the turning radius parameter dynamically by distributing driving force differently to left and right wheels. Based on detected turning situations (parking, U-turn, etc.), the controller adjusts the driving force distribution ratio to achieve a reduced turning radius while maintaining the long wheelbase configuration for stability.
2Ease of operation
If driving force distribution is performed to improve turning performance, then turning radius is reduced, but driver confusion increases because the operation differs from driver's experience and will
Solution Approach 1:
The system provides feedback to the driver by displaying the expected driving path on a display device. This visual feedback shows the driver how the vehicle will turn with the adjusted driving force distribution, allowing the driver to understand and anticipate the vehicle's behavior before executing the maneuver, thereby reducing confusion.
Solution Approach 2:
The system performs preliminary calculation and display of the expected driving path before the actual turning maneuver. By showing the driver the anticipated vehicle trajectory in advance, the driver can mentally prepare and align their expectations with the vehicle's actual behavior, reducing the information gap.
