The invention provides an electronic parking brake system, a state recognition method of a switch module of the electronic parking brake system and a storage medium. According to the state identification method, the first setting signal corresponding to one switch channel is turned into the second setting signal at intervals in each polling period, so that the state of the corresponding switch channel is adjusted into the setting state of the second setting signal; the states of the corresponding switch channels are changed based on the conduction relation between the switch channels in different states of the switch module, the states of the switch channels are detected after the switch channels are turned into the second setting signals each time, so that a group of state sets is obtained, the state sets with the number the same as that of the switch channels are obtained in the polling period, and the polling efficiency of the switch module is improved. And the state of the switch module can be judged according to the comparison result of the plurality of groups of state sets and the state truth table in the polling period. The state of the switch module is judged by using multiple groups of state sets, so that misjudgment is avoided, and the state recognition accuracy of the switch module is relatively high.

    本发明提供一种电子驻车制动系统及其开关模块的状态识别方法、存储介质。本发明的状态识别方法在每个轮询周期内间隔地将其中一路开关通道对应的第一置位信号翻转为第二置位信号,从而将对应的开关通道的状态调整为第二置位信号的置位状态,进而基于在开关模块的不同状态下的各路开关通道之间的导通关系来改变相应的开关通道的状态,在每次翻转为第二置位信号后便检测各路开关通道的状态,从而得到一组状态集,在轮询周期内得到与开关通道的数量相同的状态集,并可根据轮询周期内的多组状态集和状态真值表的对照结果来判断开关模块所处的状态。本发明利用多组状态集来判断开关模块的状态,避免了误判,对开关模块的状态识别精确度较高。
