The focus of this paper is the control strategy used to control general parallel hybrid electric vehicles (HEV). The torque split control problem of HEV is formulated as the optimal control of a switched system. A model-based strategy for fuel-optimal control is presented. The optimal control problem of such a switched system is formulated as a two-stage optimization problem. Dynamic programmin...

An intelligent Global Positioning System (GPS) based control system utilises information about the current vehicle position and upcoming terrain in order to reduce vehicle fuel consumption as well as improve road safety and comfort. The development of such in-vehicle control systems has provided static and dynamic road information. The vehicle running parameters have been mathematically defined...

An electronic stability program (ESP) system for passenger cars can be utilized effectively to stabilize a skidding vehicle and thus make the vehicle more controllable to reduce the risk of traffic accidents and to improve driving safety. In this paper, a vehicle multi-body dynamic model constructed using MSC.ADAMS/Car is adopted to investigate the reliability of the ESP system. To improve cont...

The intelligent vehicle is a complicated nonlinear system, and the design of a path tracking controller is one of the key technologies in intelligent vehicle research. This paper mainly designs a lateral control dynamic model of the intelligent vehicle, which is used for lateral tracking control. Firstly, the vehicle dynamics model (i.e., transfer function) is established according to the vehic...

Abstract: Control systems for converter-controlled rail vehicles are orders of magnitude more complex than controllers for previous generations of vehicles. While the dynamic behaviour of previous generations of vehicles was to a large extent determined by its power components alone, an important part of the dynamics of modern vehicles is shaped by real-time software, distributed computing and ...

The paper presents the preliminary result of the development of the eDPP (enhanced Dynamic Path Predictor) during overtaking situations. The eDPP application offers a higher degree of accident prevention through: advanced driver-information and driver-warning strategies; improved actuation using the new and enhanced ADASIS v2 (Advanced Driver Assistance Systems Interface Specifications, version...

Compared with traditional aircraft, the near space hypersonic unmanned aerial vehicle control system design must deal with the extra prominent dynamics characters, which are differ from the traditional aircrafts control system design. A new robust adaptive control design method is proposed for one hypersonic unmanned aerial vehicle (HSUAV) uncertain MIMO nonaffine block control system by using ...

Torque vectoring (TV) is one of the most promising technologies in vehicle dynamics control as it has the potential to provide distinctive benefits for mobility and agility of all-wheel drive ground vehicles. Especially in all-terrain driving, TV control can support both vehicle stability and driving efficiency. Within this context, the paper presents the state-of-the-art in TV control and intr...

We discuss the development, integration, simulation, and flight test of a manned vehicle UAV mission system in a partially-known environment. The full control system allows a manned aircraft to issue mission level commands to an autonomous aircraft in realtime. This system includes a Natural Language (NL) Interface to allow the manned and unmanned vehicle to communicate in languages understood ...

At very high speeds, bubbles form in the underwater vehicles because of sharp trailing edges or of places where the local pressure is lower than the vapor pressure. These bubbles are called cavities and the size of the cavities grows as the velocity increases. A properly designed cavitator can induce the formation of a single big cavity all over the vehicle. Such a vehicle travelling in the vap...
