An electronic parking brake switch, system and method wherein the switch includes a handle assembly, a reset assembly including a reset contact and a reset switch, an application assembly including an application contact and an application switch, and a release assembly including a release contact and a release switch, the reset switch, the applying switch and the releasing switch form a first switch loop, the reset contact, the applying switch and the releasing switch form a second switch loop, and the handle assembly can conduct all the contacts and all the switches on all the switch loops in a time-sharing mode. According to the electronic parking brake switch, each switch loop can adopt a non-single trigger signal, common cause failure is prevented, the parking brake and parking release functions are ensured, the redundant design of the electronic parking brake switch is realized, the reliability of the electronic parking brake switch is improved, and the reliability and safety of an electronic parking brake system are improved.
本发明涉及一种电子驻车制动开关、系统和方法,其中开关包括手柄组件、复位组件、施加组件和释放组件,复位组件包括复位触点和复位开关,施加组件包括施加触点和施加开关,释放组件包括释放触点和释放开关,复位开关、施加触点和释放触点形成第一开关回路,复位触点、施加开关和释放开关形成第二开关回路,手柄组件能够分时导通各开关回路上的各触点和各开关,由于复位开关与施加开关、释放开关分别设置于不同的开关回路中,保证了各开关回路都能采用非单一的触发信号,防止共因失效,保证了驻车制动和驻车释放的功能,实现了电子驻车制动开关的冗余设计,提高了电子驻车制动开关的可靠性,提高了电子驻车制动系统的可靠性和安全性。
