The invention discloses a hydraulic braking control method, a domain controller, a hydraulic braking assembly and a vehicle, the hydraulic braking control method is applied to the domain controller, the domain controller is used for controlling the hydraulic braking assembly, and the hydraulic braking assembly comprises an electronic hydraulic braking system EHB, a hydraulic backup unit and a driving motor. The EHB is connected with the hydraulic backup unit through a hydraulic loop; the method comprises the steps that when an EHB is abnormal and a hydraulic backup unit is normal, a target deceleration request of a vehicle, the maximum hydraulic backup deceleration of the hydraulic backup unit and the maximum reverse dragging deceleration of a driving motor are obtained; and when the first braking force jointly provided by the maximum hydraulic backup deceleration and the maximum reverse drag deceleration meets the target deceleration request, the hydraulic backup unit and the driving motor are controlled to provide braking force for the vehicle. Therefore, the vehicle has higher braking capacity when the EHB is abnormal and the hydraulic backup unit is normal, so that the redundant braking capacity of the vehicle is enhanced, and the safety of the vehicle is improved.
本发明公开了一种液压制动的控制方法、域控制器及液压制动总成、车辆,其中,液压制动的控制方法应用于域控制器,域控制器用于控制液压制动总成,液压制动总成包括电子液压制动系统EHB、液压备份单元和驱动电机,EHB和液压备份单元通过液压回路连接;方法包括:在EHB异常且液压备份单元正常时,获取车辆的目标减速请求、液压备份单元的最大液压备份减速度、以及驱动电机的最大反拖减速度;当最大液压备份减速度和最大反拖减速度共同提供的第一制动力满足目标减速请求时,控制液压备份单元和驱动电机给车辆提供制动力。由此,使车辆在EHB异常且液压备份单元正常时具备更高的制动能力,从而增强了车辆的冗余制动能力,提高了车辆的安全性。
