Car with intelligent key system and tire pressure monitoring system

Abstract

The invention discloses a car with an intelligent key system and a tire pressure monitoring system. The car comprises four tires, a plurality of antennas, the tire pressure monitoring system, the intelligent key system and a communication control system, wherein pressure sensors are arranged in the tires; the communication control system is used for controlling the antennas and the pressure sensors to communicate through a first wireless interface, and controlling the antennas and intelligent keys to communicate through a second wireless interface, so as to enable the pressure sensors to communicate with the tire pressure monitoring system through the first wireless interface and to enable the intelligent keys to wirelessly communicate with the intelligent key system through the second wireless interface; and the first wireless interface is different from the second wireless interface. Therefore, the car with the intelligent key system and the tire pressure monitoring system can save the antenna quantity and reduce the overall cost.

Description

technical field [0001] The invention relates to a car, in particular to a car with an intelligent key system and a tire pressure monitoring system. Background technique [0002] When a car is running at high speed, tire failure is the most worrying and most difficult to prevent for all drivers, and it is also an important reason for sudden traffic accidents. How to prevent tire blowout has become an important topic for safe driving. It is the key to prevent tire blowout to keep the standard tire pressure running and find tire leak in time. Tire pressure is an important indicator that affects the driving performance and safety performance of a car. 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 at this time, the grip of the tire will be affected, and the friction of the tire will be weakened, resulting in a decrease in braking performance. In addition, when the ...

Problems solved by technology

When the tire pressure is too high, the contact area between the tire and the ground will be reduced. At this time, the pressure on the tire will be relatively increased, and the grip of the tire will be affected, which will weaken the friction of the tire and lead to a decrease in braking performance.

In addition, when the car is driving on uneven roads, such as passing through ditches or bumpy roads, the tires and wheel frames are easily deformed due to the impact of driving on uneven roads, and there is not enough space in the tires to absorb vibrations. In addition to affecting driving stability and riding comfort, and even cause a tire blowout, it will also increase the impact on the suspension system, which will also cause harm

At the same time, the hidden danger of tire blowout at high temperature will increase accordingly

When the tire pressure is too low or air leaks, the friction between the tire and the ground will increase exponentially, which will not only cause abnormal tire wear or damage to the internal mechanism of the tire, but also increase fuel consumption. When driving, because the sidewall of the tire is the weak part of the tire, when the tire pressure is too low, it will be continuously squeezed and stretched, which will easily cause fatigue failure, and may cause a blowout. In addition to serious damage to the tire, it is very likely accidental traffic accident
