The embodiment of the invention discloses a brake control system with complete EPB redundancy. The brake control system comprises a brake-by-wire unit, an EPB control unit and a power supply end, the brake-by-wire unit comprises a brake-by-wire chip, a first CAN communication module and an EPB switch interface circuit; the brake-by-wire chip is electrically connected with the first EPB motor and the second EPB motor through the first motor driving module and the EPB control switching module; the EPB control unit comprises an EPB control chip and a second CAN communication module; the EPB control chip is electrically connected with the first EPB motor and the second EPB motor through the second motor driving module and the EPB control switching module. According to the scheme of the embodiment of the invention, complete redundancy of power input, the power management module, wheel speed input, CAN communication, the MCU module and the EPB motor pre-drive module is realized; and the redundant EPB control module can realize redundant EPB control by driving a two-way EPB motor.

    本发明实施例公开了一种完全EPB冗余的制动控制系统,包括:线控制动单元、EPB控制单元和电源端;线控制动单元包括线控制动芯片、第一CAN通信模块和EPB开关接口电路;线控制动芯片通过第一电机驱动模块、EPB控制切换模块与第一EPB电机和第二EPB电机电性连接;EPB控制单元包括EPB控制芯片、和第二CAN通信模块;所述EPB控制芯片通过第二电机驱动模块、EPB控制切换模块与第一EPB电机和第二EPB电机电性连接。本发明实施例的方案实现了电源输入、电源管理模块、轮速输入、CAN通讯、MCU模块、EPB电机预驱模块的完全冗余;且冗余EPB控制模块可通过驱动双路EPB电机来实现冗余EPB控制。
