Gyroscope road state recognizing and prompting method based on vehicle-road cooperation

The invention relates to a gyroscope road state recognizing and prompting method based on vehicle-road cooperation. The method comprises the steps of sensing a pitch angle generated in the driving process of a vehicle by virtue of a high-precision gyroscope mounted on the vehicle, judging whether pits, bulges and the like exist on the road according to the change condition of the pitch angle in the driving process, marking the recognized bumpy road positions, uploading the recognized bumpy road positions to a roadside unit, and broadcasting road state information to vehicles which are about topass through the road by virtue of the roadside unit so as to remind drivers of subsequent vehicles of paying attention. Compared with the prior art, the subsequent vehicles can be efficiently prompted in real time based on the real-time driving information of the vehicles, so that the driving experience can be improved; and the method is good in practicability and easy for popularization. 本发明涉及种基于车路协同的陀螺仪道路状态识别及提示方法，该方法
