Automated Tire Monitoring Device To Detect Punctures Along With Wear And Tear
The automobile industry is one of the most important factors for economical development in India. Development in the automobile industry is huge. Yet there is a lot of small things to be discovered. We already know some of the various sensors or equipment are being pre-installed in these motorized vehicles so a normal human with zero knowledge of machine can know the condition of his/her vehicle. One of the most common sensors is the temperature sensor, also the proximity sensor for the detection of the presence of an object. An automated tire monitoring device can be considered one to be in the future.
But one thing which these sensors lack is to inform when the tires should be changed, the wear and tear of the tires must be taken into consideration and the individual should know its condition while using it. When tires wear out, they lose traction and grip, especially in chilly weather and on rainy days. This poses significant safety to both pedestrians and drivers. This will be done using an automated tire monitoring device.
In new-generation car pressure sensors are already built in the tires, but what about wear and tear? Recently it has been in the news that Bridgestone Americas Technical Center in Akron, Ohio, researchers began wondering how they could measure and monitor tire wear. Coming up with a method to make such a measurement would undoubtedly save lives and money.
Ph.D. electrical and computer engineering student Akarsh Prabhakara explained. “Wear measurement today is either done manually with a coin or using full resolution laser scans,” and added, “Neither of these techniques provides an optimum solution to mount on a car and to deal with different kinds of debris that may stick in the tire over time.
It was challenging to design tech for such utilization.” After some experimentation with Bridgestone, the team decided on utilizing radar technology. A radar device is mounted over a tire, on the tire well. Millimeter-wave radar is common in vehicles today. It’s used for collision avoidance, cruise control, and other such features.
Our system repurposes these radars for tire wear and tear estimation.” The technique utilized in this device is the Inverse Synthetic Aperture. This technique benefits from the tire’s rotation to boost the resolution of the radars, enabling them to measure millimetric changes. Also, we embedded in metallic additions that serve as markers. These help the radar get the reflection in low visibility environments, such as dusty or snowy roads.
