Goals and goal fulfilment

The course syllabus states the course goals in terms of learning outcomes, i.e., knowledge, skills and attitudes to be acquired by the student during the course.

3. How understandable are the course goals?

The goals are difficult to understand»2 5%
The goals give some guidance, but could be clearer»20 58%
The goals clearly describe what I am supposed to learn»7 20%

Genomsnitt: 2.85

- Where were they?» (I have not seen/read the goals)
- They were made during the course.» (The goals are difficult to understand)
- The report was more important than the actuall simulation in matlab.» (The goals give some guidance, but could be clearer)
- The goals needs to be more specified.» (The goals give some guidance, but could be clearer)

4. Are the goals reasonable considering your background and the number of credits?

Answer this this question and the succeeding one, only if you do know the course goals.

30 svarande

No, the goals are set too low»6 20%
Yes, the goals seem reasonable»23 76%
No, the goals are set too high»1 3%

Genomsnitt: 1.83

- The course level was not appropriate (not master level, a lecturer seriously asked if the students know what a derivation is ...) The tasks and the assignments are formulated very "fluffy", which is not better even though it was on purpose. If this is intended, the criterias and the way of grading have to be obvious and clear.» (No, the goals are set too low)
- The assignment 2 needs too much simulink programming knowledge unfortunately.» (No, the goals are set too high)

5. Did the examination assess whether you have reached the goals?

32 svarande

- The assignment working classes were very important for help with ass 2. The lectures are always hard to have a "red thread" through them all when there is so many different teachers who only know their own subject.» (Some extent)
- More teaching in how to create these different powertrains such as parallel hybrid and maybe some example of how it could be build up.» (Some extent)
- Most of my gained information is from the lectures. » (Large extent)

7. What did you think about the different lecturers/teachers?


- Bo Egardt is a good lecturer but his lessons about fundamental reglerteknik is not applicable to the assignment. His lectures would be much more useful if he taught us about practical programming of simulink instead.»
- Jonas Fredriksson should have been more available at the assignments lectures since he was the best teacher in QSS and seemed to know much about it. Sven: No offence, but you and Daniel didn"t help very much on the assignments, you should hold in the presentations instead, thats where you are best!»

8. What did you think about the assignments?*


- Assignment No. 1 was way too easy compared to assignment No. 2»
- The first one was a little bit too easy»
- »
- Alot about the course was about ass 2. Very good assignment, you learn alot but it must not be so hard just to get the powertrain program working!»
- The criterias for grading were not clear and I had the feeling that the grading is more "intuitive"»
- but the time it is not enough. »
- Good thoughts about the assignments but the set-up could have been better.Since our knowledge in QSS were so poor we didn"t learn that much that we wanted. Maybe you should decrease the advanced-level, not at least at the parallel hybrid and give more helping teaching on that. More defined questions in the assignment would be good, for example specify some limits that the vehicle parameters such as engine torque, size of engine, size of el. motor etc. should work at.»
- They took a lot of time that"s the only problem :)»
- The second assignment was very interesting but hard in programming. Maybe more advices or references on Internet or books could have been interesting to get to find true information, or catalogues...»
- Some QSS examples (on the board, simulink files etc.) of how to design the battery management strategies would be great.»
- Ass 1 was maybe a bit too easy, didn"t learn that much. Assignment 2 was very good, but the control strategies could have been a bit clearer.»

- Helped some when programming the parallell hybrid in ass2. Otherwise, nothing. Very expensive book.» (Small extent)
- EXPENSIVE! not so good» (Small extent)
- It was definitely possible to pass the course without the book. Either focus more on the content of the book or consider changing the literature. » (Small extent)
- It was more like trial and errror» (Some extent)
- The book is a bit expensive, most of the information needed is gained from the lectures so there might not be necessary to have the book.» (Some extent)
- The book was complicated to understand» (Some extent)
- For QSS it could be clearer» (Large extent)
- Very interesting book.» (Large extent)
- Maybe to make duplicated lecture notes with the essential of every course» (Great extent)

- Especially swedish students seemed to be preferred by Daniel Härensten. As an exchange student one could not expect to get proper help from him!!» (Very poor)
- Must have more tutors for ass 2!» (Rather poor)
- More competent people to the assignment!» (Rather poor)
- It was ok but had sometimes to wait long time before getting help on the exercise sessions.» (Rather good)
- help was not uupto the mark during the assignment sessions» (Rather good)
- Maybe Daniel had a little bit to stressed time during the assignments hours. » (Rather good)
- There were many questions and few teachers.» (Rather good)
- students and teachers are open-minded, it was a very interesting experience» (Very good)

- With better set-up and more competent teachersa to the assignments this could be a good course!» (Fair)
- Good concept but alot to improve.» (Fair)
- It felt like the lectures were not really useful for the assignments, especially the controls lectures held by Bo Edgart. It would have been much better the students together with Bo actually designed something useful together in Matlab/Simulink. His lectures were to fuzzy and NEVER applicable to what we did in the assignments.» (Fair)
- good and relevant subject» (Good)
- Since this is a big subject to learn during only 8 weeks not much very deeper knowledge was expected. However more information about existing hybrid vechicles on the market would have been nice to learn more about.» (Good)

16. What should definitely be preserved to next year?

- hand in 2 and the midterm»
- organization courses and assignment. To keep the evaluation method»
- Ass 2 is good.»
- I think it is not important to know about what is going on in the battery or even the electric motor. »
- Assignments!»
- The assignments and the layout of the exam»
- Teachers, the assignments, »
- The assignments»
- The assignments, but they need to be revised. »
- Assignments were quite interesting. »
- Assignments with simulation in matlab.Mid term test and no exam in the evaluation.»

17. What should definitely be changed to next year?

- maybe hand in 1»
- Ass 2 needs to be modified and/or tutoring lectures about simulink needs to be included. Remove Bo Egardt fundamental programming for this.»
- The level should be higher. More advanced control strategies. Shorter introductions to MATLAB and control theory (devise more study work to students)»
- instead of so many introduction lectures of all components that is better to focus on the control strategies and different driving modes.»
- Set-up and grading! Why not grade both the assignments and the mid-term?»
- Maybe one more course assistent»
- Presentations should be more "connected" to the assignments!»
- The control lectures could be improved in a such way that it can be more concrete (take examples with qss and industry)»
- The control lectures Better testing of assignments prior to doing them»
- The connection between the lectures and the assignments needs to be much better, especially the controls part. Less fuzzy theory and more about how you use design a (simple) controller in practice in simulink. Maybe a small assignment where just a controller needs to be designed?»
- The second assignment involved more of debugging complex and unknown errors in MATLAB. These issues can be ironed out.»
- Would be interesting to have some hands on practical experience (such as a laboratory, etc) »
- A easier program should be better. We spent a lot of time trying to correct minor programming mistakes in matlab.»

18. Additional comments

- To increase the time for the assignment 2»
- In the slides, it could be better when there are formulas to write the units and the signification of the letters or signs.»
