The variety of transmissions available for sale today has grown exponentially within the last 15 years, all while increasing in complexity. The result is definitely that we are now dealing with a varied number of transmitting types including manual, conventional automatic, automated manual, dual 
clutch, constantly variable, split power and natural EV.
Until extremely recently, automotive vehicle producers largely had two types of transmitting to choose from: planetary automatic with torque converter or conventional manual. Today, nevertheless, the volume of options avaiable demonstrates the changes seen over the industry.
That is also illustrated by the many various types of vehicles now being produced for the marketplace. And not simply conventional automobiles, but also all electrical 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 this method becoming more more popular, and the continuous drive among manufacturers and designers to deliver 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 sophisticated control systems. This is to guarantee that the best amount of efficiency and efficiency is delivered at all times. Manufacturers are under increased pressure to create powertrains that are completely 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 teams are on deadline, and the advancement process needs to be better and fast-paced than previously.
Until now, the use of computer-aided engineering (CAE) has been the most common way to build up drivelines. This technique involves elements and subsystems designed in isolation by silos within the business that lean toward proven component-level analysis equipment. While these are highly advanced equipment that allow users to extract very dependable and accurate data, they remain presenting data that is collected without factor of the complete system.
