tires, as the only vehicles and parts in contact with the ground, its state directly determine the safety of the vehicle, but it is the most easily overlooked a little, a lot of people do not even have to check tire concept!
You know, the United States from September 1, 2007 start, will require light trucks must be standard tire pressure monitoring system; and the European Union in 2012, November 1 after days of not equipped with tire pressure monitoring system, new passenger car models will not be certified, beginning in November 2014, passenger cars not equipped with tire pressure monitoring will not be allowed on the market and registered; even our next door South Korea also in 2013 as the mandatory installation of tire pressure monitoring project.
For domestic users, the good news, since 1 January 2020, our country will implement a mandatory tire pressure monitoring regulations.
Recently, a document called “performance requirements for passenger car tire pressure monitoring systems and test methods” by the technical review of mandatory national standards, approved by the National Standards Commission after officially promulgated. This means that the tire pressure monitoring system will become mandatory “standard” when the new car factory in the future. In simple terms, from 2020 January 1, all in the production of passenger cars will begin to implement mandatory installation of TPMS (tire pressure monitoring systems), and since then, Taobao third-party tire pressure monitoring requirements should be modified to fall dramatically !
However, a predetermined “method” is forced to install “tire pressure abnormality alarm device fault”, and the view through the policy requirements, vehicle tire pressure warning system there are two types, one is the simple alarm, another is accurate to a particular abnormal condition of the wheel. Strictly speaking, these two functions is of great distinction, although can be collectively referred to as tire pressure monitoring, but there is a certain way to realize the difference.
The first More called “alarm tire pressure” or “indirect tire pressure monitoring system.” Alarm mode which is a kind implemented by the vehicle speed sensor ABS system of the vehicle. When the gap between the wheel tire pressure is too large, it will lead to inconsistencies between the rotational speed of the wheel so as to be detected by the ABS system, so the air pressure of the vehicle inferredNow the problem.
benefits of this design is the low-cost, no other additional equipment installed. But the disadvantage is that the system can not be brought to measure tire pressure tire specific figures, and the application environment have limitations. For example, if the air pressure of four wheels there is a change (e.g. temperature, altitude and other factors) Meanwhile, tire pressure warning system does not give an accurate and prompt, it may lead to excessively low tire pressure of the tire for a long time or excessive use of tire pressure.
Another common feature is the safety monitoring tire pressure within the tire pressure sensor and signal transmission to a central control panel or vehicle trip computer, directly the current pressure in each wheel displayed a digital form, and even some can display the temperature sensor of the tire. This tire pressure monitoring function is also very common in the market after the conversion, and the price is not high, a few hundred dollars can buy a big brand of modified parts.
mainstream luxury brands have a basic standard tire pressure monitoring system, after all, the luxury brand models generally higher prices, for greater flexibility in the space between profit and cost, so the standard tire pressure monitoring is not difficult, but for non-luxury brands, the standard tire pressure monitoring is still rare.
But there are also such brands, such as Guangzhou Toyota, currently it is the whole system comes standard with a tire pressure warning system, also regarded as the first step in the implementation of the policy, in particular the price of less than 70,000 Hyun can cause the whole system comes standard with ESP stability program and tire pressure warning, really good. Ralink higher and more expensive, the price of some of the Camry and other models is to spend a tire pressure monitoring system with digital display, which is good.
In addition to guangfeng whole system comes standard tire pressure monitoring outside, some time ago has just been listed 2020 Honda Fit also the whole system was equipped with a tire pressure warning and VSA stability program, do not know after the old section GK5 owners see Yes what feelings?
As China’s auto industry started late, so in manyThe policy are not perfect, but with the implementation of “performance requirements for passenger car tire pressure monitoring systems and test methods”, I believe more and more in relation to the future of vehicle safety policies will be implemented. Tire pressure monitoring policy to be implemented, hope that the future stability program ESP, airbags etc. can become a standard security configuration in aid policy, so that for the user, the car can be more at ease.
