...James D. Van de Ven; Michael A. Demetriou Hybrid vehicles are an important step toward reducing global petroleum consumption and greenhouse gas emissions. Flywheel energy storage in a hybrid vehicle combines high energy density and high power density, yet requires a highly efficient continuously...

...Jie Duan; Mingfeng Li; Teik C. Lim; Ming-Ran Lee; Wayne Vanhaaften; Ming-Te Cheng; Takeshi Abe Powertrain noise is a major component of vehicle interior noise and thus has a significant effect on the overall sound quality. It is typically dominated by harmonics in the lower audible frequency range...

...Bin Yang; Li Keqiang; Feng Nenglian This research addresses the modeling, design, and implementation of a longitudinal acceleration tracking control (LATC) system for a test vehicle at low speeds. An electronic throttle actuator for LATC system application is introduced first, which can be used...

... for off-road vehicles is chosen. A mathematical model representing the system is derived rigorously from inertial dynamics and first principles in thermodynamics. Empirical corelations are also used to include nonlinearities such as friction that cannot be accounted for in the thermodynamic equations...

... asymptotically to a set of critical points for the cost function and hence provides (locally) optimal coverage. A key element of this approach is that the only communication required is with the nearest neighbors of the vehicle (since this is what is needed to determine the Voronoi decomposition). Figure 8...

...Gürdal Arslan; Jason R. Marden; Jeff S. Shamma We consider an autonomous vehicle-target assignment problem where a group of vehicles are expected to optimally assign themselves to a set of targets. We introduce a game-theoretical formulation of the problem in which the vehicles are viewed as self...

...Jorge Finke; Kevin M. Passino A mathematical model for the study of the behavior of a spatially distributed group of heterogeneous vehicles is introduced. We present a way to untangle the coupling between the assignment of any vehicle’s position and the assignment of all other vehicle positions...

... problems, with applications to mobile robots, unmanned air vehicles (UAVs), autonomous underwater vehicles (AUVs), satellites, aircraft, spacecraft, and automated highway systems ( 1 2 3 4 5 6 7 ), and to nonformation cooperative control problems such as task assignment, payload transport, role...

...R. Brent Gillespie; Szabolcs Sövényi Manual control performance on-board a moving vehicle is often impeded by biodynamic feedthrough —the effects of vehicle motion feeding through the operator’s body to produce unintended forces on the control interface. In this paper, we propose and experimentally...

...Dmitry V. Balandin; Nikolai N. Bolotnik; Walter D. Pilkey; Sergey V. Purtsezov For the crashworthiness analysis of transport vehicles a three-component system that consists of a base, a container, and an object to be protected, connected by shock isolators, can be utilized as a model. An approach...

To provide the operator with a controlled comfortable posture necessarily to control the vehicle effectively...

...Peter Ridley; Peter Corke This paper examines the kinematics and control of a Load Haul Dump Vehicle used in underground mining operations. The aim of the work is to develop an autonomous guidance strategy. A linear, state-space, mathematical model of the vehicle is derived purely from geometric...

...Rong Zhang; Andrew Alleyne; Eko Prasetiawan Coordination of the power distribution in a Multi-Input Multi-Output (MIMO) electro-hydraulic transmission is investigated for the case of an earthmoving vehicle powertrain. A generalized model of a representative system is presented along...

..., higher order models are required to maintain accurate lateral control of the vehicle. Neglecting these dynamics can cause the controller to become unstable at the bandwidths required for accurate control at higher speeds. The yaw dynamic model, which is found to be dominated by a second order response...

...P. Bolzern; R. M. DeSantis; A. Locatelli The problem of path-tracking for an autonomous vehicle composed of a tractor and n − 1 trailers with off-axle hitching is considered in this paper. It is shown that an input-output feedback linearization technique can be adopted both in forward and backward...

..., etc. The real-time information of the track tension is very important for tracked vehicles because the track tension is closely related to the maneuverability and the durability of tracked vehicles. In the case of longitudinal driving, a modified 3 DOF dynamics model is derived for tracked vehicles...
