Automotive hybrid technology: status, function and development tools
2008 (English)Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
Abstract [en]

A diminishing oil reserve and increased environmental concern puts new demands on our vehicles. This thesis aims to identify the strengths and weaknesses of a conventional vehicle and explain the technology behind. Alternative energy sources are introduced and together with the knowledge learnt, their potentials are discussed. Unfortunately, none of them can be found to fulfil all future demands. Instead, hybrid vehicles are identified as a solution with high potential. Hybrid vehicles are consequently defined and the additional components are explained. The multiple energy sources of a hybrid vehicle bring increased drivetrain flexibility but also increased control complexity. With the goal to enhance the fuel economy and reduce emissions, optimum operating conditions are discussed for each drivetrain component and concrete control targets are extracted. Due to the complexity, computer modelling and simulation are expected to be an essential tool when it comes to hybrid vehicle development and optimization. As a result, cost efficient component models are suggested and finally a number of control optimization procedures are compared. The result of this thesis is a summary of relevant knowledge needed to reduce the development effort of hybrid vehicles. The key aspect is to understand the synergy effect of a hybrid drive train which enables the designer to approach the full potential of each component.
