Reifendruckkontrolle

Reifendruckkontrolle, often abbreviated as RDK or TPMS (Tire Pressure Monitoring System), refers to electronic systems that monitor the air pressure inside pneumatic tires on various types of vehicles. The primary purpose of these systems is to alert the driver to a significant drop in tire pressure, which can lead to unsafe driving conditions, reduced fuel efficiency, and premature tire wear.

There are two main types of Reifendruckkontrolle systems: direct and indirect. Direct systems utilize pressure sensors mounted inside each tire, often on the valve stem. These sensors transmit real-time pressure data wirelessly to the vehicle's central computer. Indirect systems, on the other hand, use the anti-lock braking system (ABS) wheel speed sensors. They infer low tire pressure by detecting that one or more tires are rotating faster than others, indicating a loss of circumference due to underinflation.

The implementation of Reifendruckkontrolle systems has become widespread, driven by safety concerns and regulations in many countries. A properly inflated tire is crucial for optimal handling, braking performance, and stability. Underinflated tires can overheat and potentially lead to a blowout, while overinflated tires can reduce grip and cause a harsher ride. Reifendruckkontrolle systems provide a proactive safety feature, helping drivers maintain optimal tire pressure and avoid potential hazards.
