Recently, tire built-in sensors (i-Tire sensors) have been commercialized and used as tire management systems for logistics trucks.
It is a project to reduce costs by managing tire life using an i-Tire sensor that can detect tire conditions such as pressure, temperature, and deformation.
However, since the i-Tire sensor is mounted inside the tire, it is not easy to directly check the condition of the sensor.
Therefore, in this paper, we studied the technology to detect the failure of the i-Tire sensor using a tire deformation model.

As tires are the only parts that contact with road surface, they deliver all the forces from the road and have enoumous effect on most of the vehicle performance. Therefore, it is essential to set and secure tire performance targets in the early stage of vehicle development. The purpose of this study is to develop a method for setting tire performance targets to meet the vehicle performance target in the early development stage. Huge amount of tire test data and vehicle simulation data were analyzed and machine learning technology was used to develop this method.
