- Examiner and lectures: Lars Eriksson, (telephone 28 4409). The lectures are broadcasted on YouTube in the channel: Lars Lectures. Each lecture video will be according to the lecture schedule, and they will be available for the foreseeable future. If I get interesting questions that I think are of general interest, I might make new explanatory videos or material available, so stay tuned.
Exercises and hand-in assignment:

- A template is provided for handins and can be downloaded here (handin1, handin2, handin3 ).
This course treats the longitudinal behavior of road vehicles and gives a framework for analyzing and optimizing the energy consumption. Both traditional and new hybrid powertrain configurations are treated. Realistic mathematical models are developed for the components and they are compiled to complete vehicle systems that are analyzed and used to develop optimized energy management strategies.
Several case studies are used to exemplify the methodology and show the principles and challenges associated with analyzing and optimizing complex powertrains.
Learning outcomeA course participant should after the course:
- have knowledge about traditional and hybrid powertrain configurations.
- be able to identify and enumerate different hybrid drive system configurations.
- be able to discuss the advantages and disadvantages with different hybrid configurations.
- have received training in analyzing complex powertrains focusing on the perspective of energy efficient ground vehicle propulsion.
- have knowledge about tools for energy optimization of complex powertrains.
- experience in using tools for energy optimization
The lecture series follows, to a large extent, the presentation in the
Vehicle Propulsion Systems book and much attention is given to the analysis
and discussion of the Case studies. The table below gives a preliminary
schedule for the lectures, and the H-I indicate approximate positions of
when the background material for the hand-in problems has been treated in
the lectures. There can be minor changes to the contents on the lectures,
but there are no major changes planned, compared to previous years lecture 6
and 7 have switched order.
Slides for the lecture series will be posted on OH-page as soon as they are finished.

Guest lecturer, summary
Examination: Hand-in assignments
The course is examined and graded based on hand-in assignments that must be done individually. Details concerning the examination requirements are given in the document that describes the hand-in assignments.
There is a mandatory set of
In total there are four hand-in assigments, where only the first three have mandatory parts. The basic contents of the hand-in assignments and the hand in deadlines are:
- Energy requirement of a driving mission. Fuel consumption
analysis of conventional cars. A first implementation of the
different tools that are used for fuel consumption analysis.
-To be handed in at the latest: April 15 (there is some lee-way due to the mismatched information).
- Optimal driving trajectories for parallel and series hybrid
cars, the problem is solved using dynamic programming.
Another interesting scenario is the optimal speed trajectories of
a heavy truck in up- and down-hill driving.
-First part to be handed in at the latest: April 23.
-Final report to be handed in at the latest: May 05.
- ECMS-control of a parallel hybrid vehicle.
-To be handed in at the latest: May 19.
- Control strategies and fuel consumption optimization of a car with
short term storage.
Implementation and analysis of a fuel cell electrical vehicle and all other Extra Tasks.
-To be handed in at the latest: June 11.
The final deadline for submission of all mandatory assignments is June 8th 2019, if you want your grades to be reported for this semester and put on Ladok. Note that there is no guarantee that we can give feedback on assignments after that date until the next year when the course is given again.
DownloadsThe files needed for the assignments are found under the links below. Frequently asked questions and updates to the hand-in assignments will also be included there.
