The invention relates to the field of automobile safety, and discloses a vehicle anti-collision early warning system based on a millimeter wave radar, and the key point of the technical scheme is that the vehicle anti-collision early warning system comprises the millimeter wave radar, a data acquisition end, a data processing end, a reminding module and a speed regulation module, the speed regulation module is used for regulating the speed of a vehicle, and the data acquisition end comprises a data acquisition module; the millimeter-wave radar is arranged, the millimeter-wave radar is used for obtaining the distance between the vehicle and the front vehicle and the distance between the vehicle and the rear vehicle in real time, front vehicle distance data and rear vehicle distance data are generated through the data collecting end, the driving speed of the front vehicle and the driving speed of the rear vehicle are calculated, and then the front vehicle collision time and the rear vehicle collision time are obtained. A safety time range is preset in the data processing end, and the speed of the vehicle is adjusted through the speed adjusting module, so that the first absolute difference value is within the safety time range, the distance between the vehicle and the front and back vehicles is ensured, and collision is prevented.
本发明涉及汽车安全领域,公开了基于毫米波雷达的车辆防碰撞预警系统,其技术方案要点是包括毫米波雷达、数据采集端、数据处理端、提醒模块和调速模块,调速模块用以对自身车辆进行调速,数据采集端包括数据采集模块,设置有毫米波雷达,根据毫米波雷达实时获取自身车辆与前方车辆和后方车辆之间的距离,通过数据采集端生成前车距离数据和后车距离数据,并计算得出前车与后车的行驶速度,进而得到前车碰撞时间和后车碰撞时间,并在数据处理端内预设安全时间范围,通过调速模块对自身车辆进行调速,使得第一绝对差值位于安全时间范围内,来确保自身车辆与前后车辆之间的距离,防止发生碰撞。
