Redundant electronic parking brake system based on private CAN communication

The invention provides a redundant electronic parking braking system based on private CAN communication, which relates to the technical field of automobile parking braking and comprises a power supply module, two independent power control modules and a motor module. The power supply module is respectively connected with the two power control modules, the two power control modules are respectively connected with a single-side public CAN signal module, the two power control modules are connected through a private CAN communication module, and the two power control modules are respectively connected with a single-side motor in a control manner. When the power control module on one side receives a pull-up or release signal, the signal is immediately sent to the other side through the private CAN communication module, and the function of synchronous wakeup or synchronous pull-up and release on the left side and the right side is achieved. 本发明提供了一种基于私CAN通信的冗余电子驻车制动系统，涉及汽车驻车制动技术领域，包括供电模块、两个独立的电力控制模块、电机模块；供电模块分别与两个电力
