Embodiment Construction

[0041] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0042] The invention provides an abnormal tire pressure monitoring method based on an OBD diagnostic seat.

[0043] refer to figure 1 , figure 1 It is a schematic flow chart of the tire pressure abnormality monitoring method based on the OBD diagnostic seat of the present invention.

[0044] In this embodiment, the abnormal tire pressure monitoring method based on the OBD diagnostic seat includes:

[0045] Step S10, obtain the message information of the current state of the vehicle in the vehicle network system through the OBD (On-BoardDiagnostic, on-board diagnostic system) diagnostic seat;

[0046] In this embodiment, the OBD diagnostic socket is connected to CANBUS (ControllerAreaNet-workBus, vehicle-mounted network system), and the message information of the current status of the vehicle in the vehicle-mounted ...

Abstract

The invention discloses an on-board diagnostic (OBD) diagnosis base-based tire pressure abnormity monitoring method. The method comprises acquiring report information of a current state of an automobile in an automobile-mounted network system by an OBD diagnosis base, carrying out analysis on the report information to obtain rates of tires of the automobile in a preset time stage, determining if the tires of the automobile comprise a tire with abnormal tire pressure according to the rates of the tires of the automobile, and outputting prompt information when the tires of the automobile comprise a tire with abnormal tire pressure. The invention also discloses an OBD diagnosis base-based tire pressure abnormity monitoring device. The method and device realize tire pressure monitoring based on rates of tires of a vehicle, can output prompt information to give a tire abnormity prompt for a user when the tire pressure is low, are free of tire pressure detection by a pressure transducer installed in a tire and reduce a vehicle tire pressure monitoring cost.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a tire pressure abnormality monitoring method and device based on an OBD diagnostic seat. Background technique [0002] Tires are an important part of a car's running gear. As an important supporting element and walking element, tires not only carry the entire weight of the car, but also provide propulsion for the car to move forward, and at the same time play a role in easing the impact of the ground. Tires play a key role in the handling stability, smoothness, safety, comfort and fuel economy of the car. [0003] In order to ensure the safe driving of the car, a relatively common method is to install TPMS (Tire Pressure Monitoring System, Tire Pressure Monitoring System) on the car to monitor the tire pressure, temperature and other parameters in real time. The situation of tire blowout due to high temperature and high tire pressure can be displayed and alarmed with visua...
