Passenger vehicle door opening monitoring system and method
The invention provides a passenger vehicle door opening monitoring system and method. The system comprises a millimeter wave radar module, an infrared human body sensor module and a control module. When the approaching distance is smaller than or equal to a preset distance threshold value, the infrared human body sensor module is controlled to detect whether the approaching object is an organism or not; if yes, a vehicle door of the passenger vehicle is controlled to be prohibited from being opened; a door opening collision probability map is also constructed; when the passenger vehicle is kept in the target state for a time period longer than the preset time period, the vehicle position of the passenger vehicle is obtained; determining a door opening collision probability corresponding to the vehicle position from a collision probability map; determining a radar detection frequency corresponding to the door opening collision probability from a preset radar detection frequency library; and controlling the millimeter-wave radar module to detect the approaching distance of the approaching object behind the vehicle tail at the radar detection frequency. The data processing load of the system is reduced, the influence of severe weather on mobile biological detection is reduced, and the applicability of the system is improved to a great extent.
本发明提供一种乘用车辆车门开启监测系统及方法，其中系统包括：毫米波雷达模块、红外人体传感器模块、控制模块；当接近距离小于等于预设的距离阈值时，控制红外人体传感器模块检测接近物体是否为生物；当为生物时，控制乘用车辆的车门禁止开启；还构建开门碰撞概率地图；当乘用车辆大于预设的时长保持目标状态时，获取乘用车辆的车辆位置；从碰撞概率地图上确定车辆位置对应的开门碰撞概率；从预设的雷达检测频率库中确定开门碰撞概率对应的雷达检测频率；控制毫米波雷达模块以雷达检测频率检测车尾后方接近物体的接近距离。减少系统的数据处理负荷，降低恶劣天气对移动生物检测的影响，极大程度上提升了系统的适用性。
