The invention discloses an early warning method and device for brake fluid leakage, electronic equipment and a storage medium, and relates to the technical field of vehicle brake fluid leakage detection. Comprising the following steps: acquiring an actual value of system hydraulic pressure of the electric power-assisted braking system and an actual value of a motor rotation angle corresponding to the actual value; based on the actual value of the hydraulic pressure of the system, the actual value of the rotating angle of the motor and a preset data mapping table, whether the electric power-assisted braking system has the hydraulic pressure leakage problem or not is judged; and when it is determined that the hydraulic leakage problem exists, an early warning signal is sent out. The preset data mapping table indicates the corresponding relation between the hydraulic value of the system and the rotation angle of the motor when the electric power-assisted braking system works normally. After the actual value of the hydraulic pressure of the system and the actual value of the rotation angle of the motor corresponding to the actual value are determined, the two actual values are compared with the data in the preset data mapping table, the problem of hydraulic pressure leakage of the electric power-assisted braking system can be found in time, and an early warning signal is sent out.

    本申请公开了一种制动液泄露的预警方法、装置、电子设备和存储介质,涉及车辆制动液泄露检测技术领域。包括:获取电动助力制动系统的系统液压的实际值和该值对应的电机转动角度的实际值;基于系统液压的实际值、电机转动角度的实际值和预设的数据映射表,判断电动助力制动系统是否存在液压泄露的问题;当确定存在液压泄露的问题后,发出预警信号。由于预设的数据映射表指示电动助力制动系统正常工作时,系统液压值和电机转动角度之间的对应关系。在确定系统液压的实际值和该实际值对应的电机转动角度的实际值后,将上述两个实际值与预设的数据映射表中的数据进行比较,可以及时发现电动助力制动系统存在液压泄露的问题,并发出预警信号。
