WHEEL-STATE OBTAINING SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240230443 titled 'WHEEL-STATE OBTAINING SYSTEM
Simplified Explanation:
The patent application describes a system that monitors the air pressure and temperature of tires in a vehicle to detect abnormalities in tire pressure.
- Air pressure sensors are installed in each wheel to detect tire pressure.
- Temperature sensors are also installed in each wheel to detect the temperature inside the tire.
- A controller calculates the temperature conversion air pressure, which is the expected tire pressure at a set temperature, based on the detected air pressure and temperature.
- If the reduction in temperature conversion air pressure in one wheel is significantly greater than in the other wheels, the system identifies it as an abnormal tire pressure state.
Key Features and Innovation:
- Integration of air pressure and temperature sensors in each wheel.
- Calculation of temperature conversion air pressure to determine expected tire pressure.
- Abnormal tire pressure detection based on temperature conversion air pressure variations.
Potential Applications:
- Automotive industry for tire pressure monitoring systems.
- Fleet management for commercial vehicles.
- Tire manufacturing for quality control.
Problems Solved:
- Early detection of abnormal tire pressure.
- Improved safety on the road.
- Prevents tire blowouts and accidents.
Benefits:
- Enhanced vehicle safety.
- Reduced maintenance costs.
- Increased tire lifespan.
Commercial Applications:
Title: Tire Pressure Monitoring System for Enhanced Safety and Maintenance
Potential commercial uses include:
- Automotive manufacturers
- Fleet management companies
- Tire retailers
Questions about Tire Pressure Monitoring Systems:
1. How does the system determine the set temperature for calculating the temperature conversion air pressure?
- The set temperature is typically a standard value based on the operating conditions of the vehicle.
2. Can the system differentiate between gradual pressure loss and sudden leaks in the tires?
- Yes, the system can detect abnormal pressure changes that indicate sudden leaks in the tires.
Original Abstract Submitted
a wheel-state obtaining system includes: air pressure sensors each provided for a corresponding one of a plurality of wheels to detect an air pressure of a tire of the wheel; and temperature sensors each provided for a corresponding one of the wheels to detect a temperature of an inside of a tire of the wheel; and a controller. the controller obtains a temperature conversion air pressure, which is the air pressure of each tire when the temperature is a set temperature, based on a detected air pressure and a detected temperature. when a reduction amount of the temperature conversion air pressure of one of the wheels is greater than a reduction amount of the temperature conversion air pressure of each of other wheels except the one of the wheels, the controller determines that the air pressure of the tire of the one of the wheels is in an abnormal state.
