The invention provides a hydraulic braking system diagnosis method and device, electronic equipment and a storage medium, and the hydraulic braking system diagnosis method comprises the steps that in the vehicle braking process, target pressure corresponding to a main cylinder of a hydraulic braking system is obtained; when the main cylinder starts to build pressure, the pressure in the main cylinder is monitored, and pressure change information is obtained; according to the pressure change information and the target pressure, whether the residual gas in the main cylinder exceeds a target threshold value or not is judged; and when the target threshold value is exceeded, outputting a fault reminding signal. Whether the residual gas in the main cylinder exceeds the threshold value or not is determined according to the target pressure and the pressure change information of the main cylinder in the vehicle braking process, and when the target threshold value is exceeded, the fault reminding signal is output to remind a user to overhaul the vehicle, so that the situation that the vehicle is overhauled after the brake fluid is manually injected under the vacuum-free injection condition can be avoided. And the problem that the braking performance of the vehicle is reduced due to inaccurate subjective judgment on the residual gas quantity is solved, so that the safety performance of the vehicle is improved.

    本申请提供一种液压制动系统诊断方法、装置、电子设备及存储介质,该液压制动系统诊断方法包括:在车辆制动过程中,获取液压制动系统的主缸对应的目标压力;在主缸开始建压时,对主缸内的压力进行监测,得到压力变化信息;根据压力变化信息和目标压力,判断主缸内残留气体是否超过目标阈值;在超过目标阈值时,输出故障提醒信号。本申请根据车辆制动过程中主缸的目标压力和压力变化信息,确定主缸内的残留气体是否超过阈值,并在超过目标阈值时,输出故障提醒信号,以提示用户对车辆进行检修,可以避免在无真空加注条件下、手动加注制动液后,由于主观判断气体残留量不准确,出现车辆的制动性能下降的问题,进而提高车辆的安全性能。
