Car tire pressure monitoring system

Car tire pressure monitoring system Perhaps you have heard of some vehicles equipped with a tire pressure monitoring system (TPMS), this high-tech stuff just with some in high-end car, but this high-tech stuff sometimes it is not so so that. Chen Wei said he bought the car with the system, but to mention the car did not even know this feature until a puncture after this system. Chengdu Business Daily reporter master the situation, have a common drawbacks of this system is the only leak and low tire pressure warning reminder, but the high pressure, but failed to warn. Chen Wei to remind you not to believe too much in the car's tire pressure monitoring system, and sometimes their own hands to check for possible high-tech fly. Glossary

Tire pressure monitoring system (TPMS), the role of the tire pressure in the vehicle was the real-time automatic monitoring and a flat tire and low pressure alarm to ensure road safety. system type:

There are the two major types When it comes to tire pressure monitoring system, it is necessary to popularize the knowledge of the system. Currently, tire pressure monitoring system is divided into two types: one is indirect (Wheel-Speed ​​Based TPMS WSB), this system is by automobile ABS system wheel speed sensors to compare the difference in speed between the tire In order to achieve the purpose of monitoring the tire pressure. Another directly (Pressure-Sensor Based TPMS, referred to as PSB), such a system is the use of a pressure sensor installed in each tire to directly measure the tire pressure, the use of the wireless transmitter, and the pressure transmitted to the information from the tire internal central receiver module on the system, and then to be displayed on each of the tire pressure data. When the tire pressure is too low or if leakage occurs, the system will automatically alarm. pros and cons contrast:

Direct PSB is relatively better Both systems have advantages and disadvantages, the direct system can provide more advanced features, the determination of actual instantaneous pressure inside each tire at any time, it is easy to determine the tire failure. The indirect system is relatively low cost, have been equipped with four-wheel ABS (each tire is equipped with a wheel speed sensor) car simply upgrade the software, but the indirect system there is no direct system with high accuracy, it can not determine the tire failure and The system calibration is extremely complex, the system will not work in certain cases, for example, two of the same axle are both low tire pressure. So direct-the (PSB system) is the best system, car tire pressure monitoring system to accurately understand the types and functions, do not be fooled. Tire misunderstood Spare tire size on the line does not matter Category: First of all, we do a note on the car's spare tire. In general, the spare tire is mainly divided into non-full-size spare tire, full-size spare tire and inflated spare tire (used for three rows of seats models), the main difference is that the tire specifications, pattern and material. The difference is that the non-full-size spare tire with full-size spare tire four standard vehicle tire size (tire width, flat than in diameter) are consistent. In layman's terms, the non-full-size is non-standard tire sizes. Generally speaking, new car spare tire manufacturers to provide more non-full-size, on the one hand, because of the full-size spare tire will sacrifice inherently valuable interior space; addition, the non-full-size spare tire costs will be much lower; course, The vendors also said the non-full-size spare tire is only temporary, allows owners to replace the normal tire faster. Admittedly, these reasons are sufficient, there must be some truth, "fleece", full-size spare tire, the additional costs will inevitably be transferred to the car cost. For car owners, if only activities in the city, with a full-size spare tire is not much problem, because it is easy to replace the tire. But if you like to go to a deserted place to explore, it is recommended that you will quickly replace the spare tire into a full-size tires, do not repeat Mr. Chen mistakes friends thousands of miles to send tires. In fact, car factory if you want to be equipped with full-size spare tire has been controversial, shortly before the Consumers Association and the Consumer Protection Committee, Chongqing joint recommendations concern the family car spare tire security, unity is equipped with a full-size spare tire ", but according to the current The status view full-size spare tire, there is a certain degree of difficulty, only to be unified with the various owners of the car as well as the economic situation, weigh whether with. tire misunderstandings
New car of the things that are good Tire pressure is normal Suggestions: Many new cars tire pressure are high, to mention car best measured tire pressure, Generally the tire pressure control in about 2.5 more appropriate, too high or too low is not good. Recommended to regularly check the tire pressure every month, sometimes rely on the naked eye can not confirm that the air pressure is normal, it is best to go to the store to check or buy a quality and reliable detector. It is understood that Chen Wei this time the biggest reason for tire failure is the tire pressure is too high, "A lot of the new car's tire pressure high, I check the tire pressure of several tires after a puncture, the tire pressure actually as high as 3.5, and quickly reduce the tire pressure. "3.5 tire pressure is fairly good, according to Chen Wei introduced, he later learned that mentioning to a friend's new car tire pressure up to 4.0! Pressure to stones and other hard objects at high speed in the case of such a high tire pressure, tire failure probability is very high. Fortunately, Chan Wai is a master craftsman, and his car's active safety performance is also in place, so timely brakes did not happen casualties. According to further investigate and understand the Chengdu Business Daily reporter, does have a lot of new car owners to reflect the new cars have a tire pressure problem of high, so everyone at the mention of a new car is best measured tire pressure, in general, the tire pressure control about 2.5, too high or too low is not good. Tire maintenance is also very important for the tire performance and life, the correct inflator experience and safety for the traveling of the vehicle is also equally important. The tire carries the full weight of the vehicle, they will not be able to work properly when under inflated or over-inflated. Underinflated tires can lead to damage to the tire. In addition, if a tire abnormal wear, it is best to conduct a four-wheel alignment. how to check:

Help others --- in fact, it is easy to check the tire pressure, 4S shop to check what can mention a new car, the day-to-day maintenance of the car wash when so stores can also check. Yourself --- you can also buy a simple tire pressure detector, you can always check for yourself if this tire pressure detector in the maintenance shop and shop sales have generally also tens of dollars. If you are traveling by car fan, often go out to buy a simple tire air pump, this simple air pump on the trunk of the car, with prices ranging from 100 yuan to 500 yuan. Chengdu Business Daily reporter Zou Hongzhi finishing reported More car systems, we gradually teach you Chen Wei is a cross-country fans, recently, just to mention a new car soon he was anxious to Qinghai play results Ruoergai plateau tire burst. To prepare for the spare tire when he discovered that the spare tire is a non-full-size spare tire can not be long-distance travel, the most terrible is near and no place to change the tire. The last only allow friends to send a full-size tire came from Chengdu to him in the past, completed once sent thousands of miles to tire feat! Chan Wai is a master craftsman of traveling by car, and also to understand some basic common sense, he will be out of this problem, not to mention some novice. Road issue, the Chengdu Business Daily car designed to teach you about the tire pressure. Managing we will continue to explain to people some of the common automotive systems, to provide practical help to more owners.
