There is a large and growing need in the automotive industry for engineers with specialisation in electrical drives, power electronics and not least system aspects of hybrid vehicle control. This course has the ambition to give fundamental knowledge and skills in these areas.


Knowledge and Understanding

For a passing grade the doctoral student must

Competences and Skills

For a passing grade the doctoral student must have developed the ability of choosing the most suitable drive line for a hybrid vehicle for a certain range of application and of creating control strategies for hybrid drive lines.

Judgement and Approach

For a passing grade the doctoral student must have gained the self confidence to be able to model and analyze a hybrid vehicle drive system.
