Course Outline

Hybrid Drivetrain Structures

Electrical Components

Learn about the differences and characteristics of serial, parallel and power-split hybrid drivetrains. Understand the advantages/disadvantages of P0-P4 drivetrain structures in more detail.

The electrical components are the key difference between hybridized and conventional drivetrains. Therefore, the fundamentals of electrical machines, power electronics and batteries are discussed in this module.

Operating Internal Combustion Engines within Hybrid Drivetrains

Operational Modes


The use of hybrid drivetrains poses special demands for internal combustion engines in terms of operating point adaption, phlegmatization and cost optimization. In turn, this technology offers new  possibilities for the reduction of emissions and fuel consumption as well as for the  improvement of drivability.

Hybridized drivetrain feature several operational modes such as operating point shift, boost mode and recuperation due to the increased degrees of freedom. This also enables the realization of optimal regeneration modes for exhaust gas aftertreatment systems.

Operational Strategies


Practical Examples

Choosing the right operational mode in each driving situation is a complex task that is executed by the hybrid operational strategy. An overview of various optimization targets and various established strategies is given.

An overview of prominent hybrid vehicles and their specific features is given.


After having completed this course, the participants will have fundamental knowledge about hybrid vehicle drivetrains and their specific characteristics. Key aspects are the understanding of the electrical components and the differences in operating the combustion engine within a hybrid drivetrain.
