Automobile braking method, system, mobile terminal and storage medium

Abstract

The invention provides an automobile braking method, system, mobile terminal and storage medium. The method includes: when a braking signal is received, brake the automobile wheels, and acquire the current position of the automobile wheels in real time within a preset time. Braking data; draw a real-time braking curve based on the current braking data, and compare the real-time braking curve with the preset braking curve to obtain multiple fluctuation differences; when it is judged that the fluctuation difference is greater than the preset difference value, mark the coordinate points corresponding to the fluctuation difference on the real-time braking curve; when it is judged that the number of marking marks on the real-time braking curve is greater than the preset number, a marking alarm is issued; calculate the absolute value of all fluctuation differences and to obtain the current fitting degree, and when the current fitting degree is greater than the first threshold, an alarm prompt is issued. The present invention uses the construction of the real-time braking curve and the fitting design of the preset braking curve to make real-time judgment Whether the braking performance of the car is normal.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile braking method, system, mobile terminal and storage medium. Background technique [0002] Automobile braking system plays an important role in the safety of automobiles, and is one of the focuses of automobile safety research. At present, the main components in the automobile braking system are brake pedal, vacuum booster, brake master cylinder, wheel cylinder and brake. The force generated by people stepping on the brake pedal is amplified by the vacuum booster, and then acts on the brake master cylinder. After passing through the brake master cylinder, the force is transmitted to the wheel cylinder in the form of hydraulic energy, and further amplified. Finally, this part of hydraulic energy Acting on the brake, the brake action gives the wheel a braking force to make the car brake. The braking system is mainly used to reduce the speed of the vehicle or stop...

Problems solved by technology

[0003] However, with the increasing use time of the vehicle, its braking performance will continue to deteriorate, and the existing general methods are mostly based on the driving experience of the driver or the mileage of the vehicle to determine whether the braking system needs to be overhauled. The former is highly subjective, while the latter is affected by many factors. The accuracy of both judgments is low, which is not conducive to the safe driving of the vehicle. Conducive to improving its safe driving
