(IFAC Secretariat, 2013) Emirler,M.T.; Uygan,I.M.C.; Altay,I.; Acar,O.U.; Keleş,T.; Güvenç,B.A.; Güvenç,L.
A cooperating autonomous vehicle platform is introduced in this paper for research work on automated path following and cooperative mobility. This platform is implemented on the autonomous research vehicle Okanom of Istanbul Okan University. The hardware and software components added to Okanom for cooperative autonomous driving are presented. The GPS/INS system implemented in Okanom for autonomous following of GPS waypoint trajectories is explained. The low level lateral and longitudinal controllers used in this platform are given and a robust parameter space lateral steering controller design is presented. A double lane change simulation using the experimentally validated model of Okanom is used to illustrate the effectiveness of the designed steering controller. Information on experimental work in progress and past experimental work are also presented. © IFAC.

Development of automatic lift axle system for trucks with mechanical suspensions
(IFAC Secretariat, 2013) Acar,O.U.; Keleş,T.; Koç,Z.; Güner,S.; Duruş,M.; Altuǧ,E.; Güvenç,L.
In 2014, the automatic lift axle dropping system is expected to be a legal obligation for trucks in Turkey. The aim of an automatic lift axle auto-drop system is to drop the appropriate live axle of a truck automatically based on the loading condition, instead of being manually controlled by the driver. In this paper, an algorithm providing the rules defined in the mass and dimensions regulation and a simulator that can be used to test this algorithm are developed for a truck with a mechanical suspension. During the simulations, the condition of the truck's load is used as an input and the automatic lift axle system algorithm decides on the axle(s) that canot be lifted by the driver. The determination of the vertical load shared by each axle is a statically indeterminate problem and the Direct Stiffness Method is used to obtain the solution in the simulator. Simulations are used to illustrate the use of the simulator and the developed algorithm. Extensive experimental work on testing the algorithm has been conducted on a truck with a prototype automatic lift axle system. © IFAC.
