摘要：

Based on the vehicle impulse response，a method of pavement roughness identification using vehicle dynamic response was proposed. First，road roughness was taken as input and the equation of vehicle response computation based on the impulse response function was derived. Then，the impulse response function was discretized into the matrix form and a linear equation for road roughness identification was established based on the impulse response matrix. Furthermore，considering that the front and rear wheels experienced the same road roughness，the correlation matrix of the front and rear wheels was constructed，which can decrease the computational work of road roughness identification. Then，take the advantage of the continuity of the road roughness，the load shape function was used to approximate it and thus not only the unknown identification number was further reduced but also the robustness of method to noise was improved，which achieved the real time identification. At last，the effectiveness of the proposed method was verified by numerical simulation and field test. © 2023 Editorial Board of Jilin University. All rights reserved.
