What Is TPMS?

TPMS Basics

A tire pressure monitoring system helps keep drivers safe. It checks the air in each tire and warns if it gets too low. TPMS watches the air pressure inside the tires and tells the driver if it drops a lot. Drivers get updates right away, so they can avoid tire problems. This also helps save gas.

TPMS has many important parts:

• Pressure sensor
• Analog-digital converter
• Microcontroller
• System controller
• Oscillator
• Radio frequency transmitter
• Low frequency receiver
• Voltage regulator

All these parts work together to check tire pressure. They send the information to the car’s computer. Some systems also check tire heat and can spot problems with each tire.

Why Tire Air Pressure Sensors Matter

Tire air pressure sensors help keep cars safe. They measure the air in each tire and help TPMS warn drivers about changes. If a tire loses air, the sensor finds out and tells the system. Drivers can fix the tire before it gets dangerous.

Cars with tire pressure monitoring systems are safer than those without. TPMS lowers the chance of tire bursts and helps the car stay steady. By warning about low tire air, TPMS helps stop accidents. This keeps everyone in the car safer.

TPMS Types

There are different kinds of TPMS. Each kind checks tire air in its own way. The table below shows the main types and how they work:

Direct TPMS uses a tire air pressure sensor in every wheel. This gives exact numbers and fast warnings. Indirect TPMS uses wheel speed sensors to guess the air. RFID and Bluetooth TPMS use wireless signals to send data to the car or a phone.

TPMS helps drivers keep the right tire air. This makes driving safer, saves gas, and helps tires last longer. Drivers who know about TPMS can make better choices for their cars.

Direct TPMS & Tire Air Pressure Sensor

How Direct TPMS Works

Sensor Placement

Direct TPMS has a tire air pressure sensor inside each tire. The sensor is on the wheel, usually near the valve stem. This spot lets the sensor check air pressure directly. Each sensor sends its data to the car’s computer. The system checks every tire, so drivers know which tire needs help.

Real-Time Pressure & Temperature

Direct TPMS checks more than air pressure. The system also watches tire temperature. The sensors send live data to the dashboard. Drivers see alerts if a tire loses air or gets too hot. Fast feedback helps stop accidents. The system works when the car moves or stands still. Drivers get updates quickly, so they can fix problems early.

Direct TPMS Pros

Accuracy

Direct TPMS gives exact readings. The tire air pressure sensor checks the real pressure in each tire. The system does not guess. Drivers trust the numbers they see. Good data helps tires last longer and keeps people safe.

Fast Alerts

Direct TPMS sends warnings fast. The system spots changes in pressure or temperature right away. Drivers get alerts before a tire gets unsafe. Quick warnings help drivers avoid flat tires and blowouts. The system also saves fuel and helps tires last longer.

Recent studies show direct TPMS is more sensitive than indirect systems. The sensors inside the tires check both pressure and temperature. This live data helps drivers act fast and stay safe. The system lowers the chance of accidents from low tire air.

Direct TPMS Cons

Battery Life

Direct TPMS sensors need batteries. If a battery dies, the sensor stops working. Most sensors do not let users change the battery. Drivers must replace the whole sensor when the battery is dead.

Cost

Direct TPMS costs more than indirect systems. The sensors and tools for service add to the price. Some systems need special tools for setup or repair. Sensors can break during tire changes. Some drivers and shops think the systems are hard to install or fix.

Common problems with direct TPMS are higher cost, tool needs for setup, batteries that cannot be replaced, confusion about special systems, and damage during tire changes.

SOUSHINE FSRs in Direct TPMS

SOUSHINE’s Force Sensing Resistors are important in direct TPMS. These sensors check force and pressure inside each tire. The system uses this information to tell drivers about tire health. FSRs notice changes fast, so direct TPMS can warn drivers if pressure drops.

FSRs change their electrical resistance when force touches them. This helps the sensor find even small pressure changes. The sensor is inside the tire and faces tough weather. SOUSHINE makes FSRs strong for heat, cold, and lots of use. The sensors keep working after many uses.

The table below lists the technical details of SOUSHINE FSRs in direct TPMS:

FSRs in direct TPMS react very quickly. The sensor works in less than 5 milliseconds. This speed lets the system warn drivers before pressure is too low. The sensors use little power, so the battery lasts longer.

SOUSHINE makes FSRs to fit many tire types. The sensors work from -30 to 80 degrees Celsius. This means they work in hot or cold places. The sensor can last up to one million uses, so it is good for daily driving.

FSRs have high insulation impedance and low closed resistance. These things help the sensor send clear messages to the car’s computer. The system uses these messages to check pressure and give alerts. Drivers get updates right away, so they can fix problems early.

Tip: Check your TPMS often to keep sensors working well. SOUSHINE helps with picking and installing sensors.

SOUSHINE’s FSRs help direct TPMS give fast, correct, and steady tire pressure checks. The sensors help drivers stay safe by warning them about tire problems quickly.

Indirect TPMS & Tire Air Pressure Sensor

How Indirect TPMS Works

ABS Wheel Speed Sensors

Indirect TPMS uses the car’s existing systems to watch tire health. It does not use a tire air pressure sensor inside each tire. Instead, it relies on the Anti-lock Braking System (ABS) or Electronic Stability Control (ESC). These systems have wheel speed sensors. The sensors track how fast each wheel turns. When a tire loses air, its shape changes. The tire becomes smaller, so it spins faster than the others. The system notices this change and sends a warning to the driver.

Pressure Estimation

Indirect TPMS does not measure air pressure directly. It estimates pressure by comparing wheel speeds. If one tire spins faster, the system thinks it has less air. The car’s computer uses this information to guess which tire may have a problem. This method works best when the car moves in a straight line on smooth roads. Turning, braking, or rough roads can make the readings less clear. The system may not spot small changes in pressure right away.

Indirect TPMS Pros

Lower Cost

Indirect TPMS costs less than direct systems. It uses sensors already in the car, so there is no need to buy extra parts. This makes it a good choice for drivers who want to save money. Car makers also like this system because it keeps the price of the car lower.

No Extra Sensors

Indirect TPMS does not need a tire air pressure sensor in each wheel. The system uses the ABS wheel speed sensors that are already part of the car. This means there are fewer parts to break or replace. Drivers do not have to worry about changing batteries in the sensors.

Note: Indirect TPMS can help drivers keep track of tire health without adding new hardware.

Indirect TPMS Cons

Less Accurate

Indirect TPMS is not as accurate as direct systems. It only estimates pressure by looking at wheel speed. Many things can affect how fast a wheel turns. For example, rough roads, sharp turns, or braking can change the readings. The system may not notice small drops in air pressure. Sometimes, all tires can lose air slowly, and the system will not give a warning.

• Indirect TPMS is generally less accurate than direct sensors.
• The system can miss slow leaks or small pressure changes.
• Driving conditions can make the readings less reliable.

Slower Alerts

Indirect TPMS often takes longer to warn drivers about low tire pressure. The system needs the car to move for a while before it can spot a problem. If a tire goes flat while the car is parked, the system may not notice until the car moves again. Sometimes, it takes many miles before the warning light turns on. This delay can make it harder for drivers to fix problems quickly.

Tip: Drivers should check tire pressure often, even if the TPMS does not show a warning.

SOUSHINE FSRs in Indirect TPMS

SOUSHINE makes Force Sensing Resistors for cars. Indirect tpms uses wheel speed sensors most of the time. Some car makers want more data for better safety. FSRs can give extra information to help. They measure force and pressure very well. This helps engineers build systems that find tire pressure changes faster.

FSRs change their resistance when force touches them. This lets them find small pressure changes. When used with indirect tpms, FSRs can spot slow leaks. They also notice sudden drops in tire pressure. This makes the warning system work better.

Car makers can put FSRs in different places on the tire or wheel. These sensors send live data to the car’s computer. The system compares this data with wheel speed sensor data. If both systems see a problem, the car warns the driver sooner.

SOUSHINE builds FSRs for tough weather. The sensors work in heat and cold. They last through many uses. Their low power use saves the car’s battery. FSRs come in many shapes and sizes for different cars.

Note: FSRs can make indirect tpms more correct. This helps drivers trust their tire pressure readings.
