A watch in developments of intelligent tire inspection and monitoring

The comfort and safety of driving tightly depends on good working condition of the vehicle tires. However, it is not easy for people to estimate tire pressure, temperature and tire/road friction force etc. correctly, especially when driving on road. As a result, numerous novel tire sensors and inspection devices were developed in the last two decades to make driving more safe and comfortable. In addition, these approaches also related to scrap tire pollution and highway noise reduction. This paper presents a brief survey of the recent advances in this field with a special focus on SAW tire sensors.
