TPMS is the abbreviation of Tire Pressure Monitoring System. TPMS first appeared as a special term in July 2001. In response to the requirements of the United States Congress for vehicle installation TPMS legislation, the Department of Transportation and the National Highway Traffic Safety Administration (NHTSA) jointly evaluated the two existing tire pressure monitoring systems (TPMS), and confirmed the superior performance and accurate monitoring ability of direct TPMS. Therefore, as one of the three major safety systems of automobile, TPMS tire intelligent monitoring system, together with automobile airbag and anti-lock braking system (ABS), has been recognized by the public and received due attention.
Porsche 959, the world's first vehicle with tire pressure monitoring system, was installed in 1986. In recent years, some countries have stipulated that new vehicles should be equipped with tire pressure monitoring system.
The Functions of TPMS
Tire pressure monitoring system is a kind of active safety equipment, which can alarm the tire in time when there are dangerous signs and reminds the driver to take corresponding measures, so as to avoid the occurrence of serious accidents.
With the tire pressure monitoring system, we can keep the tires in the specified pressure and temperature range at any time, so as to reduce the damage of the tire and prolong the service life. Some data shows that when the tire pressure is insufficient, and the wheel pressure is 10% lower than the normal value, the tire life will be reduced by 15%.
When the air pressure of the tire is too low, the contact area between the tire and the ground will be increased, thus increasing the friction resistance. When the tire pressure is 30% below the standard air pressure, the fuel consumption will increase by 10%.
When the air pressure in the tire is too high, it will lead to the reduction of the shock absorption effect of the tire itself, thus increasing the burden of the vehicle shock absorption system. Long-term driving with this kind of tires will cause great damage to the engine chassis and the suspension system. When the tire pressure is too high, the contact area between the tire and the ground will be reduced, and the pressure on the tire will be relatively increased, and the grip of the tire will be affected. In addition, when the vehicle passes through the ditch or bumpy road, there is not enough space to absorb vibration in the tire, which will not only affect the driving stability and ride comfort, but also increases the impact on the suspension system, which will also cause harm. At the same time, the hidden danger of tire bursts at high temperature will also increase accordingly. If the tire pressure is not uniform, it is also easy to cause brake deviation, thus increasing the wear of the suspension system.
