The invention provides a vehicle redundancy safety control method and system.The method comprises the steps that whether a drive-by-wire chassis meets the drive-by-wire brake condition or not is judged; if the drive-by-wire chassis does not meet the drive-by-wire brake condition, a first brake level signal is sent to a redundancy control unit; wherein the redundancy control unit is used for sending a first pneumatic braking instruction to the drive-by-wire chassis based on a first braking level signal; the drive-by-wire chassis is used for executing pneumatic braking operation according to the first pneumatic braking instruction; if the drive-by-wire chassis meets the drive-by-wire brake condition, whether all non-brake modules on the drive-by-wire chassis report errors or not is judged; if the non-brake module reports an error, a first drive-by-wire brake instruction is sent to the drive-by-wire chassis; the drive-by-wire chassis is further used for executing the drive-by-wire brake operation according to the first drive-by-wire brake instruction. Through the method, the stability of vehicle brake-by-wire is improved.

    本申请提供了一种车辆冗余安全控制方法及系统,其中,该方法包括:判断线控底盘是否满足线控制动的条件;若线控底盘不满足线控制动的条件,则向冗余控制单元发送第一制动电平信号;其中,冗余控制单元用于基于第一制动电平信号向线控底盘发送第一气动制动指令;线控底盘用于根据第一气动制动指令执行气动制动操作;若线控底盘满足线控制动的条件,则判断线控底盘上的各个非制动模块是否报错;若非制动模块报错,则向线控底盘发送第一线控制动指令;其中,线控底盘还用于根据第一线控制动指令执行线控制动操作。通过该方法,提高车辆线控制动的稳定性。
