This review discusses key technologies of intelligent tires focusing on sensors and wireless data transmission. Intelligent automobile tires, which monitor their pressure, deformation, wheel loading, friction, or tread wear, are expected to improve the reliability of tires and tire control systems. However, in installing sensors in a tire, many problems have to be considered, such as compatibility of the sensors with tire rubber, wireless transmission, and battery installments. As regards sensing, this review discusses indirect methods using existing sensors, such as that for wheel speed, and direct methods, such as surface acoustic wave sensors and piezoelectric sensors. For wireless transmission, passive wireless methods and energy harvesting are also discussed.
本综述讨论了智能轮胎的关键技术，重点是传感器和无线数据传输。智能汽车轮胎能够监测其压力、变形、车轮负载、摩擦力或胎面磨损情况，有望提高轮胎及轮胎控制系统的可靠性。然而，在轮胎中安装传感器时，必须考虑许多问题，例如传感器与轮胎橡胶的兼容性、无线传输以及电池安装等。关于传感方面，本综述讨论了使用现有传感器的间接方法，如用于轮速的传感器，以及直接方法，如表面声波传感器和压电传感器。对于无线传输，还讨论了无源无线方法和能量收集。
