The invention provides a vehicle-mounted road condition detection system, which comprises a detection unit, a calculation unit and a control unit, and is characterized in that the detection unit is used for sending a detection signal and receiving a ground clutter signal; the calculation unit is used for calculating the curve change rate of the ground clutter signal; the control unit is used for adjusting the current driving state of the vehicle when the curve change rate exceeds a first threshold value. According to the invention, road condition detection can be completed only by means of a radar, a camera is not needed, and the system composition is simpler; the method is not influenced by weather conditions, can more accurately and quickly obtain road surface conditions, and judges whether the road surface has a bumpy condition or not and whether the road surface is covered by ice, snow and rainwater or not; the system is simpler and more convenient, is integrated with other parts of the vehicle, and is high in adaptability.

    本发明提供了一种车载路况探测系统,包括,探测单元,计算单元和控制单元,所述探测单元用于发送探测信号和接收地杂波信号;所述计算单元用于计算所述地杂波信号的曲线变化率;所述控制单元用于当所述曲线变化率超过第一阈值时,调整车辆当前的行驶状态。本发明可以仅靠雷达即可完成对路况的探测,无需摄像头,系统构成更为简单;且不受天气情况的影响,能够更加准确快速的获取路面情况,判断路面是否出现坑洼情况,以及是否被冰雪、雨水覆盖的危险情况;系统更加简便,与车辆的其他部件集成,适配性高。
