| Electrically Assisted Infinitely Variable Transmission |
Brief Description
This project brings together two new technologies that can offer a solution in the reduction of fuel consumption and CO2 emissions from internal combustion engine vehicles.
The infinitely variable transmission (IVT) developed by Torotrak is being reviewed for its fuel saving potential, around 20% improvement over conventional automatic transmissions.
The axial flux permanent magnet motor/generator, under development by Newage, provides the opportunity for an electrical machine in series with the internal combustion engine, configurable to operate in a variety of modes.
The main aim is to develop a solution to the integration of these two devices into an automotive powertrain, resulting in a proof of concept that will combine excellent fuel economy and driveability in a single vehicle.
Benefits
The technology resulting from this programme, will produce environmental benefits arising from reduced CO2 emissions.
Progress So Far
Complete system simulation models have been developed and used for both design and controller development. The electrical machine and associated systems have been fitted to a prototype vehicle with an IVT and final system commissioning is taking place with modified controllers. The vehicle has recently been moved to Cranfield for final test and calibration and the further validation of the simulation models.
