Tire self-inspection system and tire self-inspection method

Abstract

The invention provides a tyre self-inspection system and a tyre self-inspection method. The tyre self-inspection system comprises a collecting unit and a control unit, wherein the collecting unit is used for collecting the first travel speed and the wheel speed of the No. x wheel of a vehicle; the control unit is used for calculating the No. x sliding ratio of the No. x wheel according to the collected first travel speed and the No. x wheel speed and judging if the No. x sliding ratio is bigger than the corresponding No. x threshold value of the No. x wheel. The tyre self-inspection method comprises the following steps: collecting the first travel speed and the No. x wheel speed of the No. x wheel of the vehicle; comparing and judging if the No. x sliding ratio is bigger than the corresponding No. x threshold value of the No. x wheel according to the collected first travel speed and the No. x wheel speed of the No. x wheel, wherein n and x are natural numbers, n is larger than or equal to 1, x is larger than or equal to 1 and smaller than or equal to n. According to the tyre self-inspection system and the tyre self-inspection method provided by the invention, a driver is enabled to get more comprehensive and accurate exception information of tyres, and safety hidden dangers of the vehicle caused by tyre abnormality are fundamentally eliminated.

Description

technical field [0001] The invention relates to the field of tire automatic detection, in particular to a tire self-inspection system and a tire self-inspection method based on the detection of wheel tire slip rate. Background technique [0002] With the improvement of people's living standards, cars have gradually entered every family and become a very common means of transportation. Therefore, the safety of vehicles determines the travel safety of every driver.

[0002] With the improvement of people's living standards, cars have gradually entered every family and become a very common means of transportation. Therefore, the safety of vehicles determines the travel safety of every driver. Among them, the use of tires is the An important element in vehicle safety, but for ordinary drivers, the inspection of the tire condition of their own vehicle usually depends on regular vehicle maintenance or annual inspection, and they rarely take the initiative to check the tire condition, or even do not at all The cognition of tire inspection does not know how to distinguish whether the tires have been worn out. In this way, the mastery of the condition of the vehicle tires must rely entirely on the driver to check actively, but it is often easy to forget and neglect the driver in daily life. pose a potential danger

[0003] According to incomplete statistics, more than 70% of traffic accidents on expressways are caused by blown tires, but only less than 10% of drivers have the habit of actively checking the condition of tires. It can be seen from this that , the abnormal problem of tires has always been one of the most worrying and most difficult to prevent vehicle driving hazards for all drivers

The function of the tire pressure monitoring system (Tire Pressure Monitoring System, TPMS), which has been widely used in cars at present, is to assist the driver in monitoring the tire pressure status, because maintaining the standard tire pressure while driving and discovering the tire leak immediately is the key to preventing the tire from blowing out. Two key elements, specifically, TPMS can issue an abnormal alarm at the early stage of abnormal tire pressure, such as low tire pressure, high tire pressure, rapid air leakage, high tire temperature and other fault conditions, TPMS will issue abnormal alarms, however , tire abnormalities such as excessive tire wear and insufficient tread patterns cannot be directly detected by TPMS, but these abnormalities are also likely to cause safety hazards such as tire blowout, tail flicking or excessive braking distance when the vehicle is driving at high speed or emergency braking. Therefore, how can It is extremely important for the driver to know more comprehensive tire abnormal information at all times to eliminate potential safety hazards during vehicle driving
