The Autark Hybrid in a Test Vehicle: First Results

Abstract

Nowadays the task to diminish energy consumption and air pollution caused in large shares by road traffic occupies a key issue. One possible approach is the Autark Hybrid, a well balanced configuration of an usual internal ic-engine, an electric motor with dedicated battery system in combination with a CVT of wide ratio range. Main target of the drive train is to reduce fuel consumption. After designing this powertrain at Technische Universita¨t Mu¨nchen a prototype vehicle has been assembled in order to verify the concept under real circumstances. Starting from its standard configuration a compact class vehicle has been modified. The test vehicle already started operation on a roller test bench as well as on separate testing roads and in public road traffic. Function and handling characteristics are demonstrated.
