The invention is suitable for the technical field of intelligent driving, and particularly relates to an intelligent driving road safety area judgment system and method.The system comprises a target sensing unit, a visual grid dividing unit, a calculation judgment unit and a planning control unit, and the target sensing unit is used for recognizing the type of a target in front of a vehicle by conducting image collection; the target sensing unit is used for sensing a target vehicle and collecting a relative distance and a relative vehicle speed between the target vehicle and the current vehicle, the visual grid division unit is used for carrying out grid processing on an image collected by the target sensing unit and outputting grid coordinates, the calculation and judgment unit carries out redundancy judgment, and the planning control unit carries out track planning on the current vehicle. And completing the control of the current vehicle. According to the method, the current vehicle speed, the target speed and the course angle are combined, the precision of the effective target relative speed is indirectly improved, support of target-related accurate data is provided for a subsequent transverse and longitudinal control module, and the comfort and safety of the intelligent driving function are more finely improved.
本发明适用于智能驾驶技术领域,尤其涉及一种智能驾驶道路安全区域判断系统及方法,所述系统包括目标感知单元、视觉网格划分单元、计算判断单元和规划控制单元,目标感知单元用于通过进行图像采集,识别车辆前方目标的类型,并采集目标车辆与当前车辆之间的相对距离以及相对车速,视觉网格划分单元用于对目标感知单元采集的图像进行网格化处理,并输出网格坐标,所述计算判断单元进行冗余判断,规划控制单元对当前车辆进行轨迹规划,完成对当前车辆的控制。本发明在结合当前车速和目标速度、航向角,间接提升了有效目标相对速度的精度,为后续横纵向控制模块提供的目标相关精准数据的支撑,更加精细的提升了智能驾驶功能的舒适性和安全性。
