Embodiment Construction

[0019] A method for judging and reminding road conditions based on tire pressure sensing, comprising

[0020] A. The step of obtaining the tire pressure data fed back by the tire pressure sensor node;

[0021] B. A step of displaying and transferring the tire pressure data;

[0022] C. A step of generating an air pressure change curve according to the dumped tire air pressure data;

[0023] D. The step of intercepting the air pressure change curve in each preset time interval T0, and comparing and judging the air pressure change curve, and making a road condition judgment result including at least flat road, undulating road and bumpy road;

[0024] E. The step of making a text or voice reminder according to the above road condition judgment result.

[0025] The judgment criteria for the road condition judgment result are the number of peaks appearing on the air pressure change curve within the preset time interval T0, and the difference between the height of the peaks and th...

Abstract

The invention discloses a road condition judgment prompt method based on tire pressure sensing. The method comprises a step of obtaining tire pressure data returned by a tire pressure sensing node, a step of displaying and transferring the tire pressure data, a step of generating pressure change curves according to the transferred tire pressure data, a step of extracting the pressure change curves within every preset time interval T0 and comparing and judging the pressure change curves to obtain a road condition judgment result at least including a level road, a rough road and a jolt road, and a step of correspondingly performing the character or voice prompt according to the road condition judgment result. The method realizes the judgment of the driving road condition according to the analysis of tire pressure data when obtaining tire pressure information so as to protect the driving safety.

Description

technical field [0001] The invention relates to a method for judging and reminding road conditions based on tire pressure sensing. Background technique [0002] The tire pressure monitoring system is referred to as "TPMS", which is the abbreviation of "tire pressure monitoring system". This technology can automatically monitor the various conditions of the tires in real time by recording the tire speed or electronic sensors installed in the tires, and can provide effective safety guarantees for driving. Driving under different road conditions, the wheels, axles and other components bear different pressures. If you do not pay attention to the actual road conditions and speed up, it is likely to cause damage to the wheel shaft and transmission mechanism; especially for undulating or bumpy road conditions, it is easy to damage the vehicle chassis. Contents of the invention [0003] Based on the background technology, the present invention proposes a road condition judgment ...
