Automobile tire pressure sensor principle is how to work ah? Some cars don't have sensors installed in the tire valve. How do you detect low pressure? How do you monitor and alarm automatically?
Detection principle1 、 direct tire pressure monitoringDirect tire pressure monitoring device is the use of pressure sensors installed in each tire to directly measure the tire pressure, using a wireless transmitter will send information from the tire to the central receiver module, and then the tire pressure data display. When the tire pressure is too low or leak, the system will alarm automatically.2 、 indirect tire pressure monitoringThe principle of indirect tire pressure monitoring is that when the pressure of a tire is lowered, the weight of the vehicle will reduce the rolling radius of the wheel, causing its speed to be faster than that of other wheels. By comparing the speed difference between the tires, to achieve the purpose of monitoring tire pressure. The indirect tire warning system actually monitors the air pressure by calculating the tire rolling radius.There are two main solutions to the tire pressure monitoring system, the direct system and the indirect system.Direct tire pressure monitoring system is the direct measurement of tire pressure by the pressure sensor is installed in every tire in, and the tire pressure display and monitoring, when the tire pressure is too low or when there is leakage, the system will automatically alarm.The indirect tire pressure monitoring system uses the wheel speed sensor of the automobile ABS system to compare the speed difference between the tires to achieve the purpose of monitoring the tire pressure:1, can not display accurate instantaneous pressure value of each tire;2, the same axle or the same side of the wheel or all tire pressure drop at the same time, can not alarm;3, can not take into account both speed, detection accuracy and other factors.
