The invention discloses a blind area early-warning braking system for sensing the right-turn motion characteristics of a vehicle based on an inertial device. The right-turn motion characteristics of the vehicle are acquired based on a vehicle attitude sensor, and the driving attitude of the vehicle is calculated to distinguish the right-turn radius and the related blind area range; pedestrians/vehicles near the vehicle head and on the right side of the vehicle body are monitored based on intelligent optics and radar; the relative distance and azimuth angle between the pedestrians/vehicles and the vehicle body are measured in real time; and a core control unit measures and calculates the intersection point of the orientation of the target and the vehicle body and the driving track of the vehicle so as to carry out early-warning braking operation. According to the invention, vicious safety accidents can be prevented from occurring when the right-turn blind area of a large carrying vehicle is large, dangers can be actively recognized and prevented, and final early warning braking operation is warned at a dangerous moment.

    本发明公开了一种基于惯性器件感知车辆右转运动特性的盲区预警制动系统,基于车辆姿态传感器对车辆右转运动特性进行采集,计算车辆行驶的姿态区分右转的半径及相关盲区范围;同时基于智能光学+雷达对车头附近及车身右侧车的行人/车辆进行监测;实时测算行人/车辆距离车体的相对距离和方位角;核心控制单元通过测算目标与车身的方位与车辆行驶轨迹的交汇点,进而做出预警制动操作;本发明能够避免大型运载车辆在右转盲区较大时发生恶性安全事故,能够主动识别、主动防范危险产生,并在危险时刻警醒最终预警制动操作。
