Integration and control aspects of vehicles with continuously variabletransmissions


Research objectives and content
Powertrain studies at the University of Bath are aimed to allow the freedom of individual transport to be maintained whilst limiting the effect of pollution and environmental damage from cars. The use of a continuously variable transmission (CVT) is a key component and opens up completely different possibilities in terms of engine/ vehicle control to those equipped with a conventional transmission. The potential exists to improve the efficiency of the powertrain and diminish the emissions as well as achieving good driveability. However, the aspects governing driveability of CVT vehicles are not yet fully understood and research of a fundamental nature is required. The successful establishment of such strategies is a key element in increasing the commercial penetration of CVTs, in which European industry currently has a leading place world wide. Training content (objective, benefit and expected impact)
The work will be an integrated study on dynamic aspects of a vehicle powertrain involving the following training activities:- modelling and simulation of the powertrain- development of control strategies for the powertrain by means of the simulation work- experimental work executed on a rolling road dynamometer- testing of the control strategy in a FORD Orion
The project will take place within an active team of researchers providing the most appropriate environment for the experience of co-workers. Links with industry / industrial relevance (22)
The Ford Motor Company will collaborate in the project by contributing parts of the necessary test rig measuring equipment and by supplying a Mondeo car fitted with a pre-production Torotrak CVT together with incidental components as required by the project.
