The GTC II showcases the potential of intelligent 48-volt hybridisation and features a highly efficient integration of the electric motor between the internal combustion engine and the transmission.
“The GTC II’s electronic clutch supports functions such as electric launch, electric stop-go operation and energy recuperation at speeds almost down to standstill,” says Professor Peter Gutzmer, a member of the Schaeffler executive board.
The electric motor on the GTC II is integrated in the drive train by means of a belt that runs between the internal combustion engine (ICE) and the transmission. Two clutches, one upstream and one downstream of the belt, allow the internal combustion engine to be completely decoupled when required. The electric motor can then be used independently of the ICE. As a result, the GTC II supports both constant-speed electric coasting at low load, as well as electric launch, for example in stop-start driving.
The absence of any engine braking effect in deceleration phases means that more kinetic energy is available for recuperation. Also, since overrun is avoided, cooling of the engine and after treatment system is reduced.
