Hybrid vehicles use two energy sources for their propelling. In order to investigate an optimal splitting of the power flows between the engine and the electric machine, an optimal control algorithm is recalled. A new formulation using maps allows a very fast solving this problem which then may be used in real time control. In the particular case of a hybrid vehicle on a prescribed route, a new...

This paper deals with the formation control of multiple vehicles, using a combination of dynamic surface sliding control and hybrid systems. Each vehicle must perform several manoeuvres, either independently, or in a coordinated fashion as part of a vehicle formation. A dynamic surface controller is designed for each manoeuvre. Switches between manoeuvres and communication protocols between veh...

We formally verify a hybrid control law designed to perform a station keeping maneuver for a planar vehicle. Such maneuver requires that the vehicle reaches a neighborhood of its station in finite time and remains in it while waiting for further instructions. We model the dynamics as well as the control law as a hybrid program and formally verify both the reachability and safety properties invo...

This paper presents the power management strategy for a parallel hybrid electric vehicle (PHEV). The vehicle is powered by dual energy sources consisting of internal combustion engine (IC engine) as the peak power source and the electric battery as the secondary energy source. The operational principle of the power management strategy and the possible power flow patterns are described. Based on...

This paper presents a discussion arisen after reading ”A hybrid genetic algorithm that optimizes capacitated vehicle routing problem”, by Chung-Ho Wang and Jiu-Zhang Lu, (2009). Expert System with Applications (35)(pp. 2921-2936). The discussed paper presents a hybrid genetic algorithm applied to the Capacitated Vehicle Routing Problem (CVRP). When the authors present the results obtained by th...

The development of SMU-I, a new autonomous & remotely-operated vehicle (ARV) is described. Since it has both the characteristics of autonomous underwater vehicle (AUV) and remote operated underwater vehicle (ROV), it is able to achieve precision fix station operation and manual timely intervention. In the paper the initial design of basic components, such as vehicle, propulsion, batteries etc. ...

This paper examines spatial effects on hybrid-electric vehicle (HEV) adoption. This is in contrast to most existing analyses, which concentrate on analyzing socioeconomic factors and demographics. This paper uses a general spatial model to estimate the strength of ‘neighbor effects’ on HEV adoption—namely that each consumer’s HEV-adoption decision can be influenced by the HEV-adoption decisions...

Hybrid vehicles and energy management is now a fertile area of research and development. The aim of this paper is to contribute to the tools development for energy management and collaborative decision-making in hybrid electrical vehicles. We propose a multi-agent system for intelligent energy management. To test the designed and developed system, we have used a vehicle powered by a hydrogen fu...

The objective of the drive shaft is to connect with the transmission shaft with the help of universal joint whose axis intersects and the rotation of one shaft about its own axis results in rotation of other shaft about its axis. Shafts must be exceptionally tough and light to improve the overall performance of the vehicle. Automobile industries are exploring composite materials in order to obt...
