The invention provides an electronic parking brake system which comprises a first loop module which comprises an EPB switch identification sub-module and at least one EPB motor driving sub-module. The second loop module comprises at least one emergency release sub-module; at least one load EPB motor; the load EPB motor is connected with the first loop module and the second loop module. In response to a fault of the first loop module and an emergency release signal received by the second loop module, the emergency release sub-module controls the first loop module and the load EPB motor to be in a cut-off state; and the emergency release sub-module controls the load EPB motor to execute a first mode. The electronic parking brake system can be suitable for a multi-motor use scene, the problems that mechanical emergency release is inconvenient to use in some specific use environments and has safety defects are solved, and intelligence, safety and reliability of products are improved.
本发明提供了一种电子驻车制动系统,包括第一回路模块,包括EPB开关识别子模块、至少一个EPB电机驱动子模块;第二回路模块,包括至少一个紧急释放子模块;至少一个负载EPB电机;所述负载EPB电机分别与所述第一回路模块和第二回路模块连接;响应于所述第一回路模块故障且所述第二回路模块接收到紧急释放信号,所述紧急释放子模块控制所述第一回路模块与所述负载EPB电机处于切断状态;所述紧急释放子模块控制所述负载EPB电机执行第一模式。本发明的一种电子驻车制动系统能够适用多电机使用场景并克服机械式紧急释放在一些特定使用环境中使用不便利且存在安全缺陷的问题,提高了产品的智能化和安全可靠性。
