TPMS (Tire Pressure Monitoring System) technology is a system designed to monitor vehicle tire pressure in real time. This system is important to ensure that vehicles run safely and efficiently, not only to extend the tire life. TPMS is a standard feature on many modern vehicles and continues to evolve along with advances in automotive technology. This article will discuss the definition, types, how it works, benefits, and the latest developments in TPMS technology.
Definition of TPMS
TPMS is an electronic system used to monitor air pressure in vehicle tires. This system provides information to the driver if the tire pressure is too low or too high, which can be a risk to driving safety. TPMS works by using sensors installed in each tire of the vehicle to measure air pressure and send data to the vehicle’s electronic control unit.
TPMS is purposed to reduce the potential for accidents caused by improper tire pressure. Low tire pressure can lead to increased fuel consumption, vehicle instability, or even accidents. Therefore, TPMS is very important to ensure vehicle comfort, safety, and efficiency. Types of TPMS
There are two main types of TPMS technology, namely direct TPMS and indirect TPMS. Both types work differently, although their ultimate goal is the same, which is to provide information about tire pressure.
1. Direct TPMS
Direct TPMS uses sensors that are installed directly on each tire. These sensors are located inside the tire rim and measure the air pressure inside the tire directly. The data collected by the sensors is then sent wirelessly to the vehicle’s control system, which will notify the driver if there is a tire with abnormal pressure. The advantages of direct TPMS are high accuracy in measuring tire pressure and its ability to provide early warning to the driver if the tire pressure drops drastically.
2. Indirect TPMS
Indirect TPMS, unlike direct TPMS, does not use tire pressure sensors directly. Instead, this system relies on the wheel speed sensors in the anti-lock braking system (ABS) to detect changes in air pressure in the tires. When tire pressure drops, the tire diameter will decrease, which will affect wheel speed. This system will detect changes in wheel speed and indicate a decrease in pressure in one or more tires. Although indirect TPMS is less expensive and does not require additional sensors on the tires, it tends to be less accurate than direct TPMS. Indirect TPMS also require re-calibration after tire replacement or tire rotation.
How TPMS Works
How TPMS works depends greatly on the type of system used. However, in general, here is how TPMS works:
Sensors on Tires: TPMS is equipped with sensors installed on each tire. These sensors measure the air pressure in the tire and can also measure the tire temperature. The senso is a set within the tire valve
Data Transmission: The sensors will send the collected data to the vehicle’s computer system wirelessly. This uses SRD radio frequency works in 314MHz or 433MHz frequency bands. This data includes information about tire pressure and temperature. This tire information are wirelessly transmitted to the vehicle’s electronic control unit.
Warning to Driver: If one or more tires experience too much or too little pressure, the TPMS system will activate an indicator light on the vehicle’s dashboard, alerting the driver. This warning is usually a light shaped like a tire with an exclamation mark inside it.
Real-Time Monitoring: Some more advanced TPMS systems can monitor tire pressure in real time and provide more detailed information, such as the location of the problem tire.
Benefits of TPMS
TPMS provides a variety of important benefits, both for vehicle safety and efficiency. Some of the main benefits of TPMS include:
Improved Driving Safety: Under-inflated tires can increase the risk of accidents. Under-inflated tires can cause loss of control of the vehicle, while over-inflated tires can make tires more susceptible to blowouts. With TPMS, drivers can detect problems with their tires early, reducing the risk of accidents.
Improved Fuel Efficiency: Proper tire pressure can improve fuel efficiency. Under-inflated tires increase friction with the road, which leads to increased fuel consumption. With TPMS, drivers can avoid this by regularly monitoring their tire pressure.
Extend Tire Life: Incorrect tire pressure can accelerate tire wear. By maintaining proper tire pressure, tires will last longer, reducing maintenance and replacement costs.
Improves Ride Comfort: Proper tire pressure also ensures better ride comfort. Tires that are too hard or too soft can affect ride quality, making the vehicle feel more unstable or less comfortable.
Conclusion
TPMS technology provides significant benefits in terms of safety, fuel efficiency, comfort, and tire life. The system continues to evolve to provide more accurate and accessible monitoring for drivers. With more and more vehicles equipped with TPMS as standard, the system has become an essential part of the modern automotive world that prioritizes safety and driving efficiency.
