ECO - TARGET (TM)

Mild Hybrid Powertrain Concept for Future Mobility Demands

Joint research project between AVL List GmbH, GETRAG GmbH & Cie KG, ATB Antriebssysteme THIEN GmbH.

Mobility Requirements

The main issues around which compliance with future mobility requirements revolve are of an ecological and economic nature: fuel consumption should be reduced through a variety of measures, in the interests both of the environment and people’s wallets.
The constraints are already defined: in July 1998, the European Automobile Manufacturers Association (ACEA) committed to reducing fleet CO2 emissions for new vehicles to 140 g/km by 2008. By 2012, this parameter should be at the 120 g/km level. The Kyoto conference stipulated a fleet CO2 emission of 90 g/km for 2010.

However, at the same time, the topic of driving pleasure shouldn’t be neglected; without this, a vehicle will not sell, no matter how economical. So whatever strategies one chooses, reduction of emissions and driving pleasure should never be mutually exclusive.

Project Goals and Concept Approach

From this point of view, the ECO - TARGET (TM) powertrain concept offers very promising performance. Here we’re talking about a 1.2 liter diesel engine with automated 6-ratio gearbox (AMT) with a 10kW 42V electric motor fitted to the gearbox. Reflecting the collaborative nature of the project, the engine and the overall energy management originates from AVL, the gearbox from GETRAG and the electric motor from ATB Antriebssysteme Thien GmbH.

The goal is the reduction of CO2 emissions to a level of approximately 90 – 100 g/km in the NEDC with a vehicle weight of 1350kg. Comfort, response and weight should remain in the same range as those of the base model powertrain (2L diesel engine).

The mild hybrid ECO – Target powertrain was fitted to 2 test vehicles.
