Embodiment Construction

[0017] The technical solution and structure of the present invention will be described below in conjunction with the accompanying drawings in the specification to facilitate the understanding of those skilled in the art.

[0018] Such as figure 1 As shown, an automobile tire pressure monitoring system includes a low-frequency trigger and a tire pressure sensor connected between the controller and the controller. The controller and the low-frequency trigger and the low-frequency trigger use LIN bus to transmit signals, and the low-frequency trigger and tire pressure The sensors use wireless transmission signals, and the tire pressure sensor and the controller use wireless transmission signals. The tire pressure sensor includes a left front tire pressure sensor and a right front tire pressure sensor set on the front wheels, and a left rear tire pressure sensor set on the rear wheels. And right rear tire pressure sensor, low frequency trigger includes left front low frequency trigge...

Abstract

The invention belongs to the field of automobile safety control, and particularly relates to the field of control and detection for the air pressure of an automobile tire. A monitoring system for the air pressure of the automobile tire comprises a controller, a low-frequency trigger and a tire-pressure sensor, wherein the low-frequency trigger and the tire-pressure sensor are connected with the controller; an LIN bus is adopted for transmitting signals between the controller and the low-frequency trigger; a wireless mode is adopted for transmitting the signals between the low-frequency trigger and the tire-pressure sensor; a wireless mode is adopted for transmitting the signals between the tire-pressure sensor and the controller. The monitoring system has the advantages that a driver can know information such as air pressure and temperature of the vehicle tires in real time, and when the forewarning states of flat tires such as air deficiency, air leakage or overhigh tire temperature occur, the tires emit light or sound to give an alarm for reminding, so that the driver can adopt preventive measures such as speed reduction, stoppage and air supplement actively to prevent accidents from occuring.

Description

Technical field [0001] The invention belongs to the field of automobile safety control, and more specifically relates to the field of automobile tire pressure control detection. technical background [0002] Vehicles are now an important means of transportation. With the expansion of vehicle applications and the gradual increase in the number of vehicles, the rapid development of high-level highway networks has increased the speed of vehicles accordingly, so the reliability and safety of vehicles are also increasingly required. improve. In traffic accidents caused by tires and other reasons, most of the traffic accidents are caused by tire pressure problems. With the rapid growth of road traffic, overloading sites are becoming more and more serious, causing serious damage to roads, bridges, and other facilities, as well as casualties. Accidents happen frequently. Most of these traffic accidents are caused by the overpressure, underpressure, high temperature of the vehicle tires...
