Abstract
The increasing environmental awareness in today’s society has created a
demand for vehicles with less environmental impact. One way to meet the resulting need is to construct hybrid vehicles, hybrid operation which involves a combination of different energy conversion- and storage principles. This project deals with just such a hybrid solution, a parallel hybrid. To construct a competitive solution, it must both be comparable in terms of performance, comfort and price of existing vehicles on the market. Costs can be minimized by using standardized components to the extent possible.
The idea is that a standard internal combustion engine combined with a
sequential gearbox and parallel to the combustion engine is coupled an electric motor.... (More)
The increasing environmental awareness in today’s society has created a
demand for vehicles with less environmental impact. One way to meet the resulting need is to construct hybrid vehicles, hybrid operation which involves a combination of different energy conversion- and storage principles. This project deals with just such a hybrid solution, a parallel hybrid. To construct a competitive solution, it must both be comparable in terms of performance, comfort and price of existing vehicles on the market. Costs can be minimized by using standardized components to the extent possible.
The idea is that a standard internal combustion engine combined with a
sequential gearbox and parallel to the combustion engine is coupled an electric motor. The electric motor can be used as the propelling engine, both in combination with internal combustion engine and on its own. In addition, it handles the synchronization of the gearbox at gear change. Together with a shift robot, fully automated and very rapid gear changes can be achieved, without disturbing the driver. This allows more gears to be introduced and the internal combustion engine can be kept at an optimal operating point that reduces emissions and lowers fuel consumption. The electric motor also substitutes the reverse gear, acts as a starter motor and alternator, reducing the number of components.
This thesis work deals with precisely this, namely to prepare and commission
an automated sequential gearbox for a parallel hybrid. The project has
been carried out at the Department of Industrial Electrical Engineering and
Automation (IEA) at Lund University in collaboration with Saab Automobile
in Trollhättan. (Less)
