Symmetry frame between these items is asymmetric itself and has no direct expression, but it affects a vibration level on the vehicle and driving comfort. Usually, we can change only the vehicle\u2019s speed to achieve desired vibrations level of the driver and passengers. Recently, vehicle dynamic characteristics can be changed depending on its damping system structure, but these solutions are limited by construction and control possibilities and evidently represented by symmetric dependency between road input and the resulting acceleration of the vehicle. The main limitation of this process is to have a reliable value of the existing road profile that is mainly defined by road category but unpredictable for each road distance. Functional road profile calculations are provided in this article, where power spectral density (further-PSD) and waviness of the road play the main role in delineating road profile parameters. Furthermore, the transfer function system was created using full car dynamic model analysis. Values on vehicle suspension\u2019s effects on acceleration were obtained from vehicle speed and road roughness. Acceleration values and transfer function were used to calculate PSD value quickly and practically. This calculated result can be formed as a control value to the vehicle damping control. In addition, the provided methodology became useful to determine road quality for adjustment of vehicle suspension parameters and set safe driving characteristics, which became part of driver assistant systems or autonomous driving mode.<\/jats:p>","DOI":"10.3390\/sym13071149","type":"journal-article","created":{"date-parts":[[2021,6,27]],"date-time":"2021-06-27T23:57:22Z","timestamp":1624838242000},"page":"1149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Identification of Road Profile Parameters from Vehicle Suspension Dynamics for Control of Damping"],"prefix":"10.3390","volume":"13","author":[{"given":"Aurimas","family":"\u010cer\u0161kus","sequence":"first","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]},{"given":"Tadas","family":"Lenkutis","sequence":"additional","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]},{"given":"Nikolaj","family":"\u0160e\u0161ok","sequence":"additional","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0665-8829","authenticated-orcid":false,"given":"Andrius","family":"Dzedzickis","sequence":"additional","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]},{"given":"Darius","family":"Vir\u017eonis","sequence":"additional","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2458-7243","authenticated-orcid":false,"given":"Vytautas","family":"Bu\u010dinskas","sequence":"additional","affiliation":[{"name":"Department of Mechatronics and Robotics, Vilnius Gediminas Technical University, Saul\u0117tekio al. 11, LT-10223 Vilnius, Lithuania"}]}],"member":"1968","published-online":{"date-parts":[[2021,6,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Loprencipe, G., Zoccali, P., and Cantisani, G.
