A half-surrounded exclamation mark appears on the car dashboard for tire pressure monitoring.
The current tire pressure monitoring is mainly divided into two categories, one is indirect tire pressure monitoring, the other is direct tire pressure monitoring, and direct tire pressure monitoring is divided into built-in type and external type.
The principle of indirect tire pressure monitoring is very simple. The vehicle’s ABS system will monitor the tire speed in real time. When the tire pressure is too high or too low, the tire speed will change. After the ABS system detects this change, it will prompt the driver to check the tire pressure through the trip computer or the warning light on the instrument panel.
Indirect tire pressure monitoring cannot measure the pressure of each tire, only when the tire pressure is abnormal, the tire pressure monitoring will send out an alarm. Moreover, indirect tire pressure monitoring cannot determine faulty tires at all, and system calibration is extremely complicated, and in some cases the system will not work properly.
The role of tire pressure monitoring
1. Prevention of accidents
The tire pressure monitoring system is a kind of active safety equipment. It can timely alarm when the tires show signs of danger, and prompt the driver to take corresponding measures, thus avoiding serious accidents.
2. Extend tire service life
Truck Tire Pressure Monitoring With the tire pressure monitoring system, we can keep the tires working within the specified pressure and temperature range at any time, thereby reducing tire damage and prolonging the service life of tires. Some materials show that when the tire pressure is insufficient, when the tire pressure drops by 10% from the normal value, the tire life will be reduced by 15%.
3. Make driving more economical
When the air pressure inside the tire is too low, the contact area between the tire and the ground will increase, thereby increasing the frictional resistance. When the tire air pressure is 30% lower than the standard air pressure, the fuel consumption will increase by 10%.
