Tire Pressure Warning System

It is well known that tire pressure lower than normal reduces the safety of the vehicle. In consideration of active safety, a new tire pressure warning system for Advanced Safety Vehicle (ASV) has been developed. This involves the four mechanical pressure sensors, a simple structure on each wheel. This system can independently detect pressure of each tire with a high degree of precision under a broad range of vehicle speeds, and requires no adjustment. This paper describes the principle and the performance of this system.
