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.
- 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
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
tasksthat have to be completed for pass (grade 3). Then there is a set of extra tasksthat through a point system can give higher grades (4 or 5).
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: November 16.
- 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: November 23.
-Final report to be handed in at the latest: November 30.
- ECMS-control of a parallel hybrid vehicle.
-To be handed in at the latest: December 14.
- 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: December 17 (Thursday).
