Vehicle Speed Control Using Tire Temperature Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle speed control systems fail to consider tire temperature, leading to potential tire breakdown and extended travel time due to excessive heat generation, and may excessively reduce vehicle speed, prolonging the journey.
Innovation Solution
A vehicle speed control system that monitors tire temperature and adjusts speed to prevent excessive heat generation, using a control device to limit speed when tire temperature exceeds a set limit, thereby preventing tire breakdown and allowing faster travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle speed is reduced to control tire temperature, then tire breakdown is prevented, but traveling time to destination is extended
Solution Approach 1:
The system dynamically adjusts the vehicle speed parameter based on real-time tire temperature measurements. When tire temperature exceeds the threshold, the control device reduces speed to prevent overheating; when temperature is within acceptable range, the system allows higher speeds. This dynamic parameter adjustment resolves the contradiction by adapting speed to actual tire thermal conditions rather than applying fixed speed limits.
2Temperature
If vehicle speed is excessively reduced to control tire heat generation, then tire temperature is controlled, but productivity is decreased
Solution Approach 1:
The system implements a feedback control mechanism where tire temperature is continuously measured and fed back to the control device. Based on this feedback, the control device adjusts vehicle speed to maintain tire temperature within acceptable limits. This feedback loop ensures temperature control is applied only when necessary, avoiding unnecessary speed reductions that would harm productivity while still preventing tire overheating.
3Loss of time
If speed is increased to reach destination faster, then traveling time is reduced, but tire heat generation increases causing breakdown risk
Solution Approach 1:
The system makes the vehicle speed dynamic rather than fixed, adjusting it in real-time based on tire temperature conditions. When tire temperature is within safe limits, the system permits higher speeds to reduce traveling time; when temperature approaches critical levels, speed is automatically reduced to prevent tire breakdown. This dynamic speed adjustment resolves the contradiction by allowing fast travel when safe and slowing down only when necessary.
