The invention relates to a low-speed emergency braking redundancy control method, which comprises the following steps of: when an IPB (Integrating Power Braking Integrated Brake Control System) has a fault, sending an IPB fault signal to an automobile bus; the method comprises the following steps: when an ADAS (Advanced Driving Assistance System) obtains an IPB fault signal from an automobile bus and detects that there is a collision risk in front of the automobile bus, an RBU (Redundant Braking Unit) is used to complete an MEB (Manipulating Emergency Braking) braking request or trigger an ESA (Emergency Steering Assistance) function to avoid collision, and when the ADAS obtains the IPB fault signal from the automobile bus and detects that there is a collision risk in front of the automobile bus, the RBU (Redundant Braking Unit) is used to complete the MEB (Manipulating Emergency Braking) braking request or trigger the ESA (Emergency Steering Assistance) function to avoid collision; when the IPB breaks down, an RBU is used for completing an MEB braking request or triggering an ESA function to avoid collision, low-speed braking can be completed when the IPB breaks down, the low-speed driving safety of the vehicle is improved, and the situation that the braking function fails due to the IPB breaks down is eliminated.
本发明涉及一种低速紧急制动冗余控制方法,包括:IPB(integratedpower brake集成制动控制系统)发生故障时,将IPB故障信号发送到汽车总线上;ADAS(Advanced Driving Assistance System,高级驾驶辅助系统)从汽车总线上获得IPB故障信号且检测到前方有碰撞风险时,使用RBU(Redundant brake unit,冗余制动单元)完成MEB(ManeuveringEmergency Braking,低速紧急制动)制动请求或触发ESA(emergencysteering assist,紧急转向辅助)功能避免碰撞;当IPB发生故障时,使用制动冗余备份系统RBU完成MEB制动请求或触发ESA功能避免碰撞,能在IPB故障时,完成低速制动,提高车辆低速行驶安全性,排除因IPB故障导致的制动功能失灵情况的发生。
