The invention relates to a full-decoupling brake-by-wire method and system, and is applied to the technical field of brake-by-wire, and the method comprises the steps: detecting whether a brake-by-wire system has a fault or not under the condition that the brake-by-wire system is normally powered on; if yes, entering a first mechanical backup braking mode; if not, the mechanical zero point of a servo cylinder piston in the brake-by-wire system is detected; judging whether the mechanical zero point of the servo cylinder piston is detected or not; if not, entering a second mechanical backup braking mode, and continuously detecting the mechanical zero point of the piston of the servo cylinder at the same time; if yes, whether the brake-by-wire system is allowed to enter a pedal power-on braking mode or not is judged; if not, entering a normal drive-by-wire brake mode; if yes, entering a pedal power-on braking mode; detecting whether the brake-by-wire system is powered off or not; if not, returning to the step of detecting whether the brake-by-wire system has a fault; and if yes, ending the process. On the basis of ensuring the brake pedal feeling, the servo cylinder piston electrifying and zeroing can be completed.
本申请涉及一种全解耦式线控制动方法及系统,应用于线控制动技术领域,方法包括:在线控制动系统正常上电的情况下,检测线控制动系统是否存在故障;若是,则进入第一机械备份制动模式;若否,则检测线控制动系统中伺服缸活塞的机械零点;判断伺服缸活塞的机械零点是否检测完成;若否,则进入第二机械备份制动模式,同时继续进行伺服缸活塞机械零点的检测;若是,则判断是否允许线控制动系统进入踩踏板上电制动模式;若否,则进入正常线控制动模式;若是,则进入踩踏板上电制动模式;检测线控制动系统是否下电;若否,则返回检测线控制动系统是否存在故障的步骤;若是,则流程结束。本申请可在保证制动踏板感的基础上完成伺服缸活塞上电找零。
