The invention relates to a brake redundancy backup system suitable for automatic driving, and a brake method. A data acquisition sensor group is connected with an integrated electronic booster and a brake backup unit and is used for acquiring vehicle running state data; an automatic driving auxiliary subsystem is connected with the integrated electronic booster and the brake backup unit through anautomobile bus and is used for generating a brake instruction according to the vehicle running state data; the integrated electronic booster is connected with the four wheels and the two electronic parking actuators and used for responding to the braking instruction and conducting braking; and the brake backup unit is connected with the four wheels and the two electronic parking actuators and used for responding to a brake instruction and conducting braking when the integrated electronic booster breaks down. According to the system, the problem that in the related art, only research on backupof one aspect of electric power voltage buildup, ABS, electronic parking and the like is focused, and systematic integration of all functional modules and research on a highly redundant backup schemeare not performed can be solved.
本申请涉及适用于自动驾驶的制动冗余备份系统及制动方法,数据采集传感器组与集成式电子助力器、制动备份单元相连接,并用于采集车辆运行状态数据;自动驾驶辅助子系统通过汽车总线与集成式电子助力器、制动备份单元相连接,并用于根据车辆运行状态数据生成制动指令;集成式电子助力器与四个轮子以及两个电子驻车执行器相连,并用于响应制动指令,并进行制动;制动备份单元与四个轮子以及两个电子驻车执行器相连,并用于当集成式电子助力器出现故障时响应制动指令,并进行制动。本申请能解决相关技术中仅集中于针对电动助力建压、ABS、电子驻车等某一方面的备份进行研究,而未对各功能模块系统性的集成、高度冗余备份方案进行研究的问题。
