- Summary:
- With increasing pressure for reduction in CO2 emissions and stricter fuel targets from road vehicles, OEMs around the globe have to electrify their vehicle range to meet increasingly challenging emission standards in recent years and new transmission technologies are gaining more attention in different main markets. The actual and future powertrain development has three major directions in order to reduce or avoid emissions in the transportation sector: Hybrid Vehicles: Hybrid Electric Vehicles (HEV), Plug-in HEV (PHEV) Electric Vehicles (EV); Range Extender Electric Vehicle (REEV); Fuel Cell Electric Vehicles (FCEV), Range Extender FCEV (REFCEV).This paper presents a new type Hybrid transmission which is called "DHT (Dedicated Hybrid Transmission)" technology for cost-effective HEVs and PHEVs; it permits the design of very compact automatic transmissions with an integrated high-voltage electric motor on the output side of the transmission.The new DHT has 2 speed ratios, outstanding economics, mechanically simple and very compact package for the challenging A- and B-Class segment's fuel consumption and package requirements; all required and state of the art hybrid functionalities can be achieved. The new 2-speed DHT is a platform design and it can be easily changed to adapt to 1-speed DHT, 2-and 1-speed EDS (Electrical Drive System) for EV, and DET (Dedicate Electrical Transmission) for REEV system which can maximize use of the same common components in different platform products.This new 2-speed DHT platform design can significantly reduce time to market, product development costs, and production costs and at the same time increase vehicle configuration flexibility
