The object of this study is to extend 4WS idea to an n-axle vehicle in general and to simulate sonic multi-axle vehicles with the derived strategies in an attempt to determine the best steering strategy. By extending the strategies used for four-wheel steering two-axle vehicles which have been extensively studied in literature, general strategies are established for an n-axle vehicle. Using integrated nonlinear ride and handling models in Matlab & Simulink, it is shown that lateral acceleration and yaw velocity responses can be improved while keeping zero vehicle sideslip angle by steering wheels on intermediate axles.

Steering dynamics of tracked vehicles Özdemir, Mehmet Nuri; Ünlüsoy, Yavuz Samim; Department of Mechanical Engineering (2016) The main objective of this thesis study is the development of a general transient steering model for tracked vehicles which is simple, accurate, and simulation results are in agreement with test results to a satisfactory level. For modeling Matlab/Simulink platform is utilized. The model represents a general tracked vehicle having rear or front sprockets, with variable centre of gravity and wheel positions, and number of wheels. The vehicle hull is modelled as a rigid body having 3 degree of freedom; transl...
Autopilot Design for Vehicle Cornering Through Icy Roads Ahiska, Kenan; Özgören, Mustafa Kemal; Leblebicioğlu, Mehmet Kemal (2018-03-01) In this paper, vehicle cornering along roads with low friction coefficient is studied, and an autopilot design is proposed to satisfy desired handling performance. A novel hierarchical optimization approach is presented to generate offline solutions for vehicle cornering problem along roads with different friction coefficients and radii of curvature. A vehicle status definition is introduced as a function of vehicle states that contains data to indicate handling performance. At each control instant, vehicle...
Lane Change Scheduling for Autonomous Vehicles Schmidt, Klaus Verner; Schmidt, Şenan Ece (2016-05-20) The subject of this paper is the coordination of lane changes of autonomous vehicles on a two-lane road segment before reaching a given critical position. We first develop an algorithm that performs a lane change of a single vehicle in the shortest possible time. This algorithm is then applied iteratively in order to handle all lane changes required on the considered road segment while guaranteeing traffic safety. Various example scenarios illustrate the functionality of our algorithm.
Steering optimization for multiaxle vehicles with multiaxle steering Yazıcı, Cahit Bartu; Kutluay, Emir; Ünlüsoy, Yavuz Samim (2021-01-01) In this work, a method for obtaining a set of optimized maximum wheel steering angles for a multiaxle vehicle with multiaxle steering is proposed. During low-speed operations, multiaxle vehicles must have a specified minimum turning radius to traverse crowded areas. The conventional geometrically correct steering configuration may not result in the desired turning radius due to constraints on the maximum steering angles. In such cases, large tire lateral slip angles may be introduced to decrease the turning...
Dynamic modeling and analysis of 6x6 skid steered military vehicle with articulated double-acting hydro-pneumatic suspension system Türedi, Derin; Konukseven, Erhan İlhan; Department of Mechanical Engineering (2022-12-12) Vehicle simulation is an essential step for the evaluation of control algorithms on vehicles. In this respect, there are various approaches in the literature such as quarter car, half car and full car. Most of these studies have been conducted for specific use cases, for instance examining only vertical behavior of the vehicle by ignoring its longitudinal and lateral dynamics. In addition to the conventional methods, there are simulation environments which analyze the characteristic of the vehicle dynamics....
