Tire Smoke Induction Prevention System for Motor Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During certain driving maneuvers and operating conditions, tire smoke from wheel spin is inducted into the passenger cabin of a motor vehicle through the HVAC system, causing residue and odor issues.
Innovation Solution
A tire smoke induction prevention system that includes a tire smoke condition feature monitoring for potential smoke generation and a controller engaging the climate control system into recirculation mode, closing fresh air and air extractor doors to prevent smoke entry, using sensors and actuators to detect excessive tire smoke situations and activate the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the fresh air induction door is opened to provide fresh air to the passenger cabin, then air quality and ventilation are improved, but tire smoke is inducted into the passenger cabin causing residue and odor issues
Solution Approach 1:
The controller closes the fresh air induction door before tire smoke can be inducted into the passenger cabin by detecting wheel spin conditions and activating the recirculation mode in advance, preventing the harmful effect of smoke induction while maintaining the ability to provide fresh air when needed
Solution Approach 2:
The system dynamically switches between fresh air induction mode and recirculation mode based on real-time detection of wheel spin conditions, allowing the fresh air induction door to be open during normal operation and closed during tire smoke generation events
2Object-affected harmful factors
If the air extractor door is opened to extract air from the storage compartment, then air circulation is improved, but tire smoke enters the storage compartment
Solution Approach 1:
The controller closes the air extractor door before tire smoke can enter the storage compartment by detecting wheel spin conditions, preventing smoke contamination while preserving the air extraction function for normal operation
3Object-affected harmful factors
If the climate control system operates in fresh air mode during wheel spin, then interior air quality is maintained, but tire smoke is inducted through the HVAC system
Solution Approach 1:
The climate control system dynamically switches between fresh air mode and recirculation mode based on detected wheel spin conditions, automatically adjusting the air intake configuration to prevent smoke induction while maintaining climate control functionality during normal operation
Solution Approach 2:
The system uses feedback from wheel speed sensors and other vehicle systems to detect wheel spin conditions and automatically adjusts the climate control system's air intake mode, creating a closed-loop control that prevents smoke induction while preserving climate control operation

AI summary
A tire smoke induction prevention system for a motor vehicle includes a tire smoke condition feature and a controller. The tire smoke condition feature may be adapted to produce a warning signal when potential for tire smoke generation exceeds a predetermined level or likelihood. The controller is adapted to respond to such a warning signal and engage a climate control system of the motor vehicle in recirculation mode. A related method for preventing the induction of tire smoke into a passenger cabin of a motor vehicle is also provided.
