The invention discloses a vehicle brake-by-wire system and a leakage diagnosis method thereof. The vehicle brake-by-wire system comprises a main cylinder hydraulic module; a wheel side braking module; the liquid inlet module is connected between a brake liquid outlet of the main cylinder hydraulic module and a brake liquid inlet of the wheel side brake module; the liquid return module is connected between a brake liquid outlet of the wheel side brake module and a brake liquid return opening of the main cylinder hydraulic module; and the pressurizing module is connected with the liquid inlet module and is used for inputting brake liquid to the wheel side brake module. On the basis of the pressurization module, brake fluid leakage detection is carried out on the modules of the vehicle brake-by-wire system through the fluid inlet module and the fluid return module, and specific leakage modules and leakage points can be finally determined through layer-by-layer screening and judgment, so that an after-sales terminal can quickly complete problem analysis and maintenance treatment, and the service life of the after-sales terminal is prolonged. And the cost caused by mistaken replacement of parts is reduced.

    本发明公开了一种车辆线控制动系统及其泄漏诊断方法,包括主缸液压模块;轮边制动模块;连接于主缸液压模块的制动液出液口与轮边制动模块的制动液进液口之间的进液模块;连接于轮边制动模块的制动液出液口与主缸液压模块的制动液回液口之间的回液模块;以及与进液模块连接、用于向轮边制动模块输入制动液的增压模块。本发明中以增压模块为基础,通过进液模块和回液模块对车辆线控制动系统的模块进行制动液泄漏检测,通过层层筛选和判断,最终可以确定具体的泄漏模块和泄漏点,便于售后终端快速完成问题分析和维修处理,减少零部件误换带来的成本。
