The invention relates to a road surface unevenness and grade real-time identification system, and belongs to the technical field of detection in the vehicle driving process. The system comprises a vehicle dynamic response information extraction module, an information transmission module and a road surface parameter real-time identification module. Sensors used by the vehicle dynamic response information extraction module comprise a built-in magnetostriction displacement sensor, a pressure sensor and an encoder, and the information transmission module transmits information obtained by the displacement sensor, the pressure sensor and the speed sensor to an ECU in real time through a CAN bus. The road surface parameter real-time identification module compiles EMD, wavelet denoising and trained deep learning programs in the ECU, so that the road surface unevenness and grade are identified in real time. According to the method, the pavement unevenness and grade can be identified in real time, judgment is accurate, and a basis is provided for active control over the suspension; in addition, the method is high in transportability, is not limited by the type of the vehicle, and is higher in applicability to the vehicle.
