The invention discloses a fault diagnosis and processing method for a vehicle braking system and an electronic braking system, and the method comprises the steps: configuring a corresponding control parameter for an electronic control unit of the electronic braking system according to a working condition parameter during the braking of the vehicle, and setting a polling period of fault diagnosis; sequentially performing polling diagnosis in at least one fault diagnosis stage according to the control parameters, judging whether the electric control unit has a power-on fault or not according to a polling diagnosis result, and if yes, determining a fault type; and controlling the electronic braking system to select a corresponding control mode according to the fault type so as to brake based on the selected control mode. Therefore, multi-task fault synchronous diagnosis is carried out in a polling mode, and the corresponding control mode is entered according to the diagnosis result, so that the problem of time delay of power-on diagnosis is solved, accurate power-assisted output is realized, and the safety of the system is enhanced.

    本申请公开了一种车辆制动系统的故障诊断及处理方法及电子制动系统,包括:在车辆进行刹车时,根据车辆刹车时的工况参数为电子制动系统的电控单元配置对应的控制参数和设置故障诊断的轮询周期;根据控制参数依次在至少一故障诊断阶段内进行轮询诊断,并通过轮询诊断的结果判断电控单元是否存在上电故障,若是,则确定故障种类;根据故障种类控制电子制动系统选择相对应的控制模式,以基于选择的控制模式进行制动。如此,以轮询的方式进行多任务故障同步诊断,并根据诊断结果进入对应的控制模式,有助于解决上电诊断的延时问题,实现了准确的助力输出,增强系统的安全性。
