The invention relates to the technical field of electronic parking control, in particular to an independent electronic parking controller dual-redundancy dual-control system and method. The system comprises a main controller; the auxiliary controller is connected with the main controller and mutually transmits redundancy verification signals with the main controller for mutually detecting the working state of the chip, and the main controller and the auxiliary controller respectively output a first control signal and a second control signal according to the received signals; the left path pre-driver is connected with the main controller and the auxiliary controller; and the right pre-driver is connected with the main controller and the auxiliary controller and is used for driving the driving circuits of the corresponding caliper motors to work according to the first control signal and the second control signal respectively. According to the invention, through a dual-redundancy dual-control structure, the auxiliary controller can timely intervene in controlling the calipers when the main controller is damaged, so that the EPB still has certain working capability when the main controller is damaged.
本发明涉及电子驻车控制技术领域,具体涉及一种独立电子驻车控制器双冗余双控制系统及方法。系统,包括,主控制器;辅控制器,连接主控制器,与主控制器相互传输冗余验证信号用于相互检测芯片的工作状态,主控制器和辅控制器根据接收的信号分别输出第一控制信号和第二控制信号;左路预驱动器,连接主控制器和辅控制器;右路预驱动器,连接主控制器和辅控制器,分别用于根据第一控制信号和第二控制信号驱动对应的卡钳电机的驱动电路工作。本发明通过双冗余双控制结构,这样就可以使辅控制器在主控制器损坏时及时介入控制卡钳,使EPB在主控制器损坏时仍然具有一定的工作能力。
