The invention provides a modular redundancy control electronic parking brake system and brake method, a backup parking braking system is provided, a left actuator and a right actuator are controlled through two control circuits respectively, and independent control over the left parking system and the right parking system is achieved; when one path fails, the other control line is used for controlling the vehicle to park, redundancy control over vehicle parking is achieved, and parking safety of the vehicle is further guaranteed. According to the invention, the MCU, the H bridge and the execution motor are integrated into one module, so that the execution mechanism is modularized, and the universality and transportability are improved; in the electronic and electrical architecture of the whole vehicle, EPB main control software can be randomly integrated in two controllers and is not limited by controller hardware. A caliper control unit is integrated on the motor, malicious unlockingand parking caused by direct energization of the MGU are prevented, the anti-theft function and higher safety are achieved, and compared with an existing executing mechanism MGU, a vehicle anti-theftlock mechanism is omitted, and the cost is reduced.

    本发明提供了一种模块化的冗余控制电子驻车制动系统和制动方法,提供了备份驻车制动系统,通过两路控制线路分别控制左右执行器,实现了左右驻车系统的独立控制;当其中一路失效时有另一控制线路来控制车辆驻车,实现了对车辆驻车的冗余控制,进一步确保车辆的驻车安全。本发明将MCU、H桥、执行电机集成为一个模块,使执行机构模块化,提高了通用性和可移植性;在整车的电子电气架构中,EPB主控制软件可任意集成于某两个控制器中,不受控制器硬件限制。本发明将卡钳控制单元集成在电机上,防止直接对MGU通电导致恶意解锁驻车,具有防盗功能和更高的安全性,相比现有执行机构MGU取消了车辆防盗锁机构,降低了成本。
