What is the concept of OBD tire pressure monitoring? What is its role and application? Today we come to learn together, what is OBD tire pressure monitoring?
The full name of OBD is On-Board Diagnostic, which is what we often refer to as "vehicle diagnostic system". This system monitors the running status of the engine and the working state of the exhaust gas aftertreatment system at any time. Once a fault is found, it will be warned by the indicating device on the car. At the same time, the OBD system will store the fault information in the memory, and the relevant information can be read in the form of fault codes through standard diagnostic instruments and diagnostic interfaces.
In recent years, the use of OBD followed by the concept of Internet of Vehicles became more and more widely used in the field of Internet of Vehicles. In addition, because the OBD interface can be directly powered, many products have been developed based on this interface, such as OBD positioning Devices, OBD tire pressure, OBD car charger, OBD anti-theft device, obd diagnostic instrument, etc., the application scenarios are becoming more and more extensive.
In fact, the essence of obd tire pressure monitoring is to use the function of the on-board diagnostic system. It reads the ABS data of the original car through the OBD interface, monitors the number of rotations of the four wheels, and then judges whether the tire pressure is normal. When an individual tire is found When the pressure is lower than the normal value, it will alarm. OBD tire pressure monitoring can also be interconnected via mobile phone APP and vehicle system, enabling users to debug OBD tire pressure monitoring on their mobile phones.
Traditional tire pressure monitoring and direct tire pressure monitoring are divided into built-in type and external type. The price of built-in tire pressure monitoring is generally high, and it is not convenient to disassemble and install, but the monitoring accuracy and monitoring effect are very good. External tire pressure monitoring is quick disassembly, high cost performance, but short battery life. Whether it is internal or external, it is necessary to install the sensor on the wheel, but the installation position is different.
Indirect OBD tire pressure monitoring does not require the installation of sensors, nor does it take up space in the car, nor does it need to replace the battery, because it is connected to the power supply in the car, because the power is very small, so the power loss is basically negligible. Indirect tire pressure monitoring and this OBD indirect tire pressure monitoring, because it uses the original data information in the car, so no sensor can also monitor the tire pressure.
