Abstract

The invention discloses a device for checking a brake system, wherein the device comprises an acquirer, a calculator and a comparator, wherein the acquirer is used for acquiring the original data of the brake system, the calculator is used for calculating the original data depending on a preset calculating rule to obtain a calculating result, and the comparator is used for comparing the result which is calculated by the calculator with a preset comparison standard and for judging whether the original data is ineffective depending on the comparison result. The device for checking the brake system can automatically calculate various original data depending on a preset calculating rule, compare the calculating result with a comparison standard, and judge that the original data is ineffective in case that the comparison result fails to meet the preset condition or judge that the original data are effective when the comparison result meets the preset condition; and the device is short in calculation duration, short in checking cycle and high in checking efficiency.

Description

technical field [0001] The invention belongs to the field of automobile design, in particular to a braking system checking device and method. Background technique [0002] With the continuous development and progress of automobile technology, advanced braking systems have been widely used in automobiles. The automobile braking system is a series of special devices used on the automobile to make the outside world (mainly the road surface) exert a certain force on some parts of the automobile (mainly the vehicle), so as to perform a certain degree of forced braking on it, generally including: Brakes, vacuum boosters, master cylinders, brake pedals, etc. [0003] In order to ensure normal driving braking and braking safety in case of failure, it is necessary to match and check the designed vehicle braking system, and check the brakes, vacuum booster, master cylinder and parking brake in the braking system according to the calculation results. Whether the lever ratio and other...
