Abstract

The invention discloses an OBD II (On Board Diagnostic II)-based tire pressure monitoring device which comprises an OBD II data acquisition module, a tire pressure detection module, an alarm module and a processing module, wherein the OBD II data acquisition module is used for acquiring and sending rotating speed values of all wheels during running of a vehicle and an oil consumption value of the vehicle in a preset path; the tire pressure detection module is arranged on any one wheel of the vehicle, and is used for detecting and sending a tire pressure value of the wheel; an oil capacity limit value and a tire pressure limit value are set on the processing module; the processing module receives the rotating speed values of all the wheels and the oil consumption value which are transmitted by the OBD II data acquisition module. According to the OBD II-based tire pressure monitoring device, aiming at the defect existing in the detection on a tire pressure of the vehicle in the prior art, through detecting the rotating speeds of the wheels and the oil consumption, the tire pressure condition is monitored in real time. The OBD II-based tire pressure monitoring device is capable of accurately detecting the tire pressure, and saves the cost.

Description

technical field

[0001] The invention relates to an OBD II-based tire pressure monitoring device. Background technique

[0002] When the tire pressure is 30% higher or lower than the standard tire pressure, the fuel consumption will increase significantly; when the tire pressure is 35% lower than the standard tire pressure, the fuel consumption per 100 kilometers will increase by 1-3 liters; the less the air pressure, the more the fuel consumption will increase. Secondly, if the car runs for a long time under the condition that the tire pressure does not meet the standard, the speed of tire wear and damage will be 2 times or even 3 times that of the tire with the pressure meeting the standard, thus seriously affecting the economy. Therefore, tire pressure monitoring is of great significance to improving driving safety, reducing fuel consumption and reducing tire wear.

[0003] Tire pressure monitoring devices currently used in the world can be divided into two categories: di...
