The invention relates to an emergency brake control system for manipulating an emergency brake function of a host vehicle. The system comprises a distance detection module configured to detect a relative distance between the host vehicle and a surrounding obstacle, a lane detection module configured to detect a current lane of the host vehicle and a curvature of the current lane, an information processing module and a decision-making module, wherein the information processing module comprises a distance calculation unit which is constructed to be used for converting the relative distance into a lane longitudinal distance and a lane transverse distance under a vehicle body coordinate system of the host vehicle based on the current lane and the curvature of the current lane; the decision-making module comprises a judgment unit which is constructed to be used for judging whether the longitudinal distance between the lanes and the transverse distance between the lanes are larger than a predetermined first lower limit or not and a predetermined second lower limit or not respectively; and the decision module does not trigger the emergency braking function when the lane longitudinal distance is greater than the first lower limit and the lane transverse distance is greater than the second lower limit.
本申请涉及一种紧急制动控制系统,用于操控宿主车辆的紧急制动功能,其特征在于,包括:距离探测模块,构造用于探测宿主车辆与周围障碍物之间的相对间距;车道探测模块,构造用于探测宿主车辆的当前车道以及当前车道的曲率;信息处理模块,包括间距计算单元,构造用于基于当前车道以及所述当前车道的曲率将相对间距转换为宿主车辆的车身坐标系下的车道纵向间距和车道横向间距;以及决策模块,包括判断单元,构造用于判断车道纵向间距和所述车道横向间距是否分别大于预先确定的第一下限和预先确定的第二下限,其中,决策模块在车道纵向间距大于第一下限且车道横向间距大于第二下限的情况下不触发紧急制动功能。
