The electric motor solves a typical problem in automated manual transmissions very elegantly: It bridges the unavoidable thrust interruptions that occur in the AMT when shifting gears and ensures strong and smooth acceleration. “To install a powerful electric motor that delivers the desired thrust in the shifting pauses for that reason alone would be too expensive,” says Dr. Florian Mühlfeld, of systems development group manager at ZF. “With the EVconnect, we have now developed a hybrid drive with all the functionalities, including all-wheel drive and purely electric driving. At the same time, we are achieving a level of comfort and performance when shifting that is on par with that of converter or dual clutch transmissions.”
To date, hundreds of people have test-driven the compact SUV prototype vehicle equipped with the EVconnect. The vehicle itself is based on a volume-produced vehicle for the Indian market. The feedback from these drivers was very similar: “From shifting comfort and acceleration to the unnoticeable transition between combustion engine and electric motor, everyone said after their test drives that the EVconnect exceeded their expectations,” adds Mühlfeld with a smile in response to the general consensus. However, development is not yet completed. The team is working on additional features.
