What are tire pressure monitoring systems (TPMS):
Tire pressure monitoring systems (TPMS) are advanced technologies aimed at improving vehicle safety and efficiency by monitoring tire pressure. There are two main types of such systems: direct TPMS and indirect TPMS. Let me show you the basic advantages and functions of each of them:
TPMS direct (Direct TPMS)
- How it works It uses sensors installed inside each tire to measure air pressure directly. These sensors periodically send data to the vehicle control unit.
- Advantages:
- High accuracy: It provides an accurate reading of the pressure of each tire separately.
- Early warning: It alerts the driver directly when the tire pressure drops below the required level.
- Effective monitoring: Problems such as air leaks or slow leaks can be detected.
Indirect TPMS
- How it works It is based on monitoring ABS system data and speed sensors to estimate tire pressure. When the pressure changes, the tire diameter changes, which affects the speed of rotation, and the system detects this change.
- Advantages:
- Lower cost: It requires fewer sensors and uses the sensors that are already in the system.
- Less maintenance: It does not have sensors inside the tires, so it is less susceptible to damage.
- Simple: It can be installed in cars that do not have a direct TPMS system.
Common functions
- Improved safety: TPMS improves safety by ensuring that tires are properly compressed, reducing the risk of tire blowouts and improving grip on the road.
- Increase efficiency: Maintaining proper tire pressure can help improve fuel efficiency and avoid uneven tire wear.
- Alarm: The TPMS system provides visual or audio notifications when a tire pressure problem is detected, which helps the driver to take corrective action immediately.
In general, TPMS systems provide significant benefits in terms of safety and efficiency, and their presence is considered an important advantage in any modern car.
