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.
Drive and auxiliary drive. Power, torque and speed. Combustion processes - Otto, Diesel, HCCI among others. Gear - manual, automatic, CVT among others. Efficiency and emissions. Fossile fuel, bio fuel - access, cost and performance. EV, HEV - series, parallel, mild, power split, FCV. Conventional servo steering, AC, brake, compressed air and so on. Electrically driven alternatives, function, efficiency. Demands for electric machines and power electronics in vehicles. Criteria for dimensioning. Lifetime, weight, price and so on. Field reduction, starting characteristics, torque ripple and so on. Various types of control, need for sensors. Fuel cells - principle, function and construction. Advantages and drawbacks with various designs. Development trends. Electric storage media - eg batteries and super capacitors. Drive cycles, efficiency, and emission for some selected drive lines. Acceleration, start and other demands for the vehicle. Regenerative braking. The need for effect and energy storage in hybrid and FC vehicles. The course includes 28h lectures, 6hcomputer excercises and self study supported by internet course material, in total 200h.
