The variety of transmissions available 
in the market today has grown exponentially within the last 15 years, all while increasing in complexity. The result can be that we are now dealing with a varied number of tranny types including manual, standard automatic, automated manual, dual clutch, constantly adjustable, split power and real EV.
Until very recently, automotive vehicle manufacturers largely had two types of transmitting to choose from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the adjustments seen across the industry.
This is also illustrated by the countless different types of vehicles now being produced for the market. And not only conventional vehicles, but also all electric and hybrid automobiles, with each type needing different driveline architectures.
The traditional advancement process involved designing a transmission in isolation from the engine and the rest of the powertrain and vehicle. Nevertheless, this is changing, with the restrictions and complications of the method becoming more widely recognized, and the constant drive among producers and designers to provide optimal efficiency at decreased weight and cost.
New powertrains feature close integration of elements like the primary mover, recovery systems and the gearbox, and in addition rely on highly advanced control systems. This is to make certain that the best degree of efficiency and overall performance is delivered at all times. Manufacturers are under improved pressure to create powertrains that are brand new, different from and better than the last version-a proposition that’s made more technical by the need to integrate brand elements, differentiate within the marketplace and do everything on a shorter timescale. Engineering groups are on deadline, and the advancement process needs to be more efficient and fast-paced than previously.
Until now, the usage of computer-aided engineering (CAE) has been the most typical way to develop drivelines. This technique involves elements and subsystems designed in isolation by silos within the organization that lean toward proven component-level analysis equipment. While they are highly advanced tools that enable users to extract extremely reliable and accurate data, they are still presenting data that’s collected without thought of the complete system.
