Brake hydraulic control unit, control method and device thereof and vehicle

The invention discloses a brake hydraulic control unit, a control method and device thereof and a vehicle. The method comprises the steps that fault information of an associated node is responded, the fault information is written into a storage of the brake hydraulic control unit, and the associated node refers to vehicle-mounted equipment influencing the function of the brake hydraulic control unit; obtaining the erasing times of the memory; and performing hierarchical control on the brake hydraulic control unit according to the erasing times. Therefore, hierarchical control is carried out on the brake hydraulic control unit based on the erasing times, a driver can be informed of the fault problem of the vehicle in time and in a targeted mode, and the situation that the vehicle enters a power loss state under the condition of no early warning, and consequently personal safety and property safety of the driver are damaged is avoided. 本发明公开了一种制动液压控制单元及其控制方法、装置及车辆。方法包括：响应关联节点的故障信息，将故障信息写入制动液压控制单元的存储器中，其中，关联节点是指
