Most of students do not have enough experience of working in interdisciplinary team. This paper shows how some interdisciplinary control problems can be stated and solved by students with some knowledge of modern CASE tools. An example of automotive ABS (Anti-lock Braking System) is given to explain graphical approach with RUP and UML in design of a control system. Copyright © 2006 IFAC

Cooperative braking with regenerative braking and mechanical braking plays an important role in electric vehicles for energy-saving control. Based on the parallel and the series cooperative braking models, a combined model with a predictive control strategy to get a better cooperative braking performance is presented. The balance problem between the maximum regenerative energy recovery efficien...

This study explores different hybridization levels of a midsized vehicle powered by a polymer electrolyte membrane fuel cell stack. The energy buffer considered is a leadacid-type battery. The effects of the battery size on the overall energy losses for different drive cycles are determined when dynamic programming determines the optimal current drawn from the fuel cell system. The different hy...

A new method for increasing LDR in deep drawing is application of anti-lock braking system (ABS) on blank holder. In this method, instead of applying a constant force on blank and control the metal flow, the ABS system holds and releases the blank several times (20 to 50 times) which results increasing LDR. This study investigates the effect of different parameters of ABS on improving the condi...

Based on the multibody dynamics model of Electric Power Steering System(EPS) and the lateral and longitudinal dynamics vehicle model, the EPS and Anti-lock Braking System (ABS) sub-controllers and the coordination controller are respectively designed according to the motion coupling relation between the steering system and the braking system. The coordination controller supervises and coordinat...

An anti-lock braking system control is a rather difficult problem due to its strongly nonlinear and uncertain characteristics. To overcome these difficulties, robust control methods should be employed such as a sliding mode control. The aim of this paper is to give a short overview of sliding mode control techniques implemented in the control of ABS. The most used control algorithms are applied...

The Anti-lock braking system (ABS) is an active safety device in road vehicles, which during hard braking maximizes the braking force between the tyre and the road irrespective of the road conditions. This is accomplished by regulating the wheel slip around its optimum value. Due to the high non-linearity of the tyre and road interaction, and uncertainties from vehicle dynamics, a standard PID ...

The optimized use of the energy stored in induction motors during deceleration is still a competitive challenge especially for Electrical Vehicles (EV) drive systems designer and manufactures. There are many control algorithms depending on many different methodologies to reach a balance point to determine when exactly the regenerative braking will be used effectively and how long that whether i...

Abstract: A novel electric-hydraulic hybrid drivetrain incorporating a set of hydraulic systems is proposed for application in a pure electric vehicle. Models of the electric and hydraulic components are constructed. Two control strategies, which are based on two separate rules, are developed; the maximum energy recovery rate strategy adheres to the rule of the maximization of the braking energ...
