The invention discloses a safety distance prompting device and method for a vehicle on a narrow road section, and belongs to the technical field of vehicle active safety. The device comprises a sensing and prompting part installed on the top of the vehicle, transverse distance sensors installed on the two sides of a vehicle body and a longitudinal distance sensor installed on a bumper at the frontend of the vehicle. The sensing and prompting part comprises a laser emitter, a humidity sensor and a data processing module. Aiming at the problem of vehicle scratching on a narrow road, the transverse safety distance prompt and the longitudinal safety distance prompt of the vehicle are designed, so that a driver can know whether the two sides of the vehicle are scratched with other structures or not in time so as to avoid scratching accidents; and meanwhile, the safe vehicle following distance of the current vehicle is calculated by combining the air humidity, so that the longitudinal driving safety of the vehicle is ensured, and the rear-end collision caused by neglecting the vehicle following distance when the driver adjusts the left-right distance is avoided.

    本发明公开了一种狭窄路段车辆的安全距离提示装置和方法,属于车辆主动安全技术领域;该装置包括安装于车辆顶部的感知提示部件、安装于车身两侧的横向距离传感器和安装于车辆前端保险杠的纵向距离传感器;感知提示部件包含激光发射器、湿度传感器和数据处理模块;本发明针对狭窄道路上的车辆剐蹭问题,设计了车辆的横向安全距离提示和纵向安全距离提示,使驾驶员能够及时获知车辆的两侧是否存在与其他构造物剐蹭的风险,以避免剐蹭事故发生;同时,本发明通过结合空气湿度计算当前车辆的安全跟车距离,进而保证车辆的纵向行驶安全,避免驾驶人员在调整左右距离时而忽视了跟车距离而造成的追尾事故。
