The models are categorized based on how they represent the wheel-ground contact, whether they incorporate the longitudinal dynamics, and whether they consider the steering dynamics. It is demonstrated that the developed models can be used to design low-complexity controllers that enable automated vehicles to execute a large variety of maneuvers with high precision.}, keywords = {STABILIZATION; FLATNESS; Engineering, Mechanical; Nonholonomic system; Vehicle dynamics and control; Appellian approach; Single track model}, year = {2022}, eissn = {1573-269X}, pages = {1959-2004}, orcid-numbers = {Takács, Dénes/0000-0003-1226-8613; Stépán, Gábor/0000-0003-0309-2409; Orosz, Gábor/0000-0002-9000-3736} } @article{MTMT:30454943, title = {On the nonlinear dynamics of automated vehicles - A nonholonomic approach}, url = {https://m2.mtmt.hu/api/publication/30454943}, author = {Várszegi, Balázs and Takács, Dénes and Orosz, Gábor}, doi = {10.1016/j.euromechsol.2018.11.015}, journal-iso = {EUR J MECH A-SOLID}, journal = {EUROPEAN JOURNAL OF MECHANICS A-SOLIDS}, volume = {74}, unique-id = {30454943}, issn = {0997-7538}, abstract = {A simple mechanical model for the lateral and yaw motion of a vehicle is presented while taking into account rolling constraints.
