Hybrid Drive for Commercial Vehicles
“Selection of the right drive architecture for the hybrid drive to save a maximum of fuel.”
electric Double Clutch Transmission
Electric Motor integrated into the Gearbox
Such drives are fully integrated into the gearbox and combine the advantages of an RSG and an ISG. If the vehicle is at a traffic light, electricity can still be generated. On the other hand, the vehicle can be parked with the electric drive, for example, without the combustion engine running.
Hybrid drives, which are coupled via a belt, are called BSG (Belt-Start-Generator). Due to the belt transmission they have a higher speed than the combustion engine and can be installed instead of an alternator.

Cost-effective Option for Fuel Savings with BSG
Hybrid Vehicle with P0 and P2
Combination of BSG and eDCT
A very efficient drive solution for a hybrid vehicle is obtained by combining a BSG (belt stater generator) and an eDCT (electric dual clutch transmission). The main advantage of this drive combination is that the combustion engine is operated with high efficiency mainly in operating points.
