智能轮胎胎压的自动调整

Automatic Adjustment of Tire Pressure of Smart Tires

轮胎气压过低,影响汽车行驶安全。胎压过低,汽车对地面的滚动阻力就会加大,轮胎磨损加快,油耗增加,严重时就会对乘员带来安全隐患。利用压力传感器对轮胎气压实时监测,通过单片机处理单元对压差分析判断,最终启动车载气泵的开关,实现了轮胎气压的自动充气,提高汽车在道路过程中的行驶安全。

The tire pressure is too low, which affects the safety of the car. If the tire pressure is too low, the rolling resistance of the car to the ground will increase, the tire wear will accelerate, and the fuel consumption will increase. In serious cases, it will bring safety problems to the occupants. In this paper, the pressure sensor is used to monitor the tire pressure in real time, and the pressure difference is analyzed and judged through the single chip microcomputer treatment unit. Finally, the switch of the vehicle air pump is controlled, and the tire pressure is automatically inflated to improve the safety of the car in the road.
