Traditional tire pressure

Obd tire pressure monitoring has been banned abroad? Obd tire pressure monitoring was eliminated? Such remarks spread on the internet, and we should not worry about judging the authenticity of such statements. First, let's learn what obd is. How does obd tire pressure monitoring work? What is the difference between OBD tire pressure monitoring and traditional tire pressure monitoring? Let's take these questions to find our final answer.

1. What is obd?

The full name of obd is on-board diagnosis, which is often called "on-board diagnosis system". The system monitors the running state of the engine and the working state of the exhaust gas aftertreatment system at any time. Once a fault is found, it will give a warning through the indicator device on the car. At the same time, the OBD system will store the fault information into the memory, and the relevant information can be read in the form of fault codes through the standard diagnostic instrument and diagnostic interface.

2.2. Working principle of OBD tire pressure monitoring.

In fact, obd tire pressure monitoring basically uses the function of on-board diagnosis system. It reads the ABS data of the original vehicle through 0bd interface, monitors the revolutions of four wheels, and then judges whether the tire pressure is normal. When the tire pressure of individual tires is found to be lower than normal, an alarm will be issued. Obd tire pressure monitoring can also be interconnected with the in-vehicle system through the mobile APP, and users can debug obd tire pressure monitoring on the mobile phone.

3.3. What is the difference between OBD tire pressure monitoring and traditional monitoring system?

Traditional tire pressure monitoring can be divided into built-in tire pressure monitoring and external tire pressure monitoring. Built-in tire pressure monitoring is generally expensive and inconvenient to disassemble, but the monitoring accuracy and monitoring effect are very good. External tire pressure monitoring means quick disassembly and assembly, high cost performance, but short battery life. Whether it is built-in or external, it is necessary to install sensors on the wheels, but the installation positions are different. Obd tire pressure monitoring does not need to install sensors, occupy the space inside the car, or even replace the battery. Because it is connected to the power supply in the car, the power loss is basically negligible.

4.4. Is OBD reliable?

Many people question that obd tire pressure monitoring mostly comes from its monitoring accuracy. Because it uses the original data information in the car, it can monitor the tire pressure even without sensors. In terms of performance, absolutely no problem. However, like indirect tire pressure monitoring, it does not display specific tire pressure values. However, some manufacturers have improved their products to solve a problem, that is, using external sensors +obd tire pressure monitoring+mobile phone interconnection to provide more intuitive feedback information.

Is obd tire pressure monitoring reliable? )

The statement that obd tire pressure monitoring is banned or eliminated is only a few people's statement. More people look at this product with a novel and exploratory attitude. At present, there are various tire pressure monitoring devices on the market. Who will win the favor of consumers in the end, we will wait and see, don't judge arbitrarily, time will tell.
