Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire driving systems face challenges in minimizing slip between tires and the road surface, particularly in adverse road conditions such as rain or snow, requiring additional measures like snow tires or chains, which are inconvenient and demand high driving skill.
Innovation Solution
A tire driving optimization system that includes a control portion to monitor and adjust engine output based on energy consumption values from two tires, reducing fuel injection when a predetermined difference or ratio in energy consumption exceeds a threshold, thereby reducing engine output and minimizing slip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If snow tires or chains are used to prevent slip between tire and road surface, then traction is improved, but device complexity and ease of operation deteriorate due to additional equipment and troublesome usage
Solution Approach 1:
The system automatically detects tire slip conditions by monitoring rotation speeds of left and right tires, and self-adjusts engine output without requiring driver intervention or additional traction equipment. The control portion compares rotation speeds, detects instability when difference exceeds threshold, and autonomously reduces fuel injection amount to prevent slip.
Solution Approach 2:
The patent replaces mechanical traction enhancement devices (snow tires, chains) with an electronic control system that substitutes mechanical intervention with electronic fuel injection control. Instead of adding mechanical elements to improve grip, the system uses electronic sensing and control to manage engine output and prevent slip condition.
2Reliability
If snow tires or chains are used to prevent slip, then driving safety is improved, but ease of operation deteriorates due to high driving skill demand and troublesome usage
Solution Approach 1:
The system performs automatic slip detection and correction without driver action. The control portion continuously monitors tire rotation speeds, automatically determines when slip is occurring by comparing speeds against threshold values, and self-corrects by adjusting fuel injection, eliminating the need for driver skill or manual intervention.
Solution Approach 2:
The system implements closed-loop feedback by continuously monitoring tire rotation speeds, comparing the difference between left and right tires, and using this feedback to automatically adjust engine output. The control portion uses the rotation speed difference as feedback signal to determine when to reduce fuel injection, creating an automatic control system that responds to actual tire conditions.
3Productivity
If engine output is increased to improve driving performance, then productivity is improved, but slip between tire and road surface increases worsening reliability
Solution Approach 1:
The system dynamically adjusts engine output based on real-time tire slip conditions. Instead of fixed engine power delivery, the control portion continuously monitors tire rotation speeds and dynamically modifies fuel injection amount in response to detected slip conditions, optimizing the balance between driving performance and traction stability.
Solution Approach 2:
The system uses tire rotation speed difference as feedback to control engine output. When the control portion detects that the rotation speed difference exceeds the predetermined threshold, it reduces fuel injection amount to prevent slip, creating a feedback-controlled system that automatically balances power delivery with traction requirements.

AI summary
The tire driving optimization system may include a first tire that is disposed at one side of a vehicle to transmit driving torque from an engine to a road surface, a second tire that is disposed at the other side of the vehicle to transmit driving torque from the engine to a road surface, an accelerator pedal that is operated by a driver so as to control a fuel injection amount that is injected into the engine, and a control portion configured to determine a first consumption energy value that is consumed through the first tire and a second consumption energy value that is consumed through the second tire, and to adjust engine output based on the first consumption energy value and the second consumption energy value if the vehicle is unstable.
