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 tranny types including manual, standard automatic, automatic manual, dual clutch, constantly adjustable, split power and natural EV.
Until extremely recently, automotive vehicle producers largely had two types of transmission to choose from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of options avaiable demonstrates the changes seen across the industry.

That is also illustrated by the many different types of vehicles now being produced for the marketplace. And not only conventional automobiles, but also all electrical and hybrid vehicles, with each type requiring different driveline architectures.

The traditional advancement process involved designing a transmission in isolation from the engine and all of those other powertrain and vehicle. Nevertheless, this is changing, with the limitations and complications of this method becoming more widely recognized, and the continuous drive among manufacturers and designers to provide optimal efficiency at reduced weight and cost.

New powertrains feature close integration of elements like the prime mover, recovery systems and the gearbox, and also rely on highly sophisticated control systems. This is to make sure that the very best amount of efficiency and efficiency is delivered all the time. 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 components, differentiate within the marketplace and do it all on a shorter timescale. Engineering groups are on deadline, and the advancement process must be more efficient and fast-paced than previously.
Until now, the usage of computer-aided engineering (CAE) has been the most common way to build up drivelines. This technique involves Driveline gearboxes components and subsystems designed in isolation by silos within the business that lean toward proven component-level analysis equipment. While these are highly advanced tools that allow users to extract very dependable and accurate data, they remain presenting data that’s collected without thought of the whole system.

While this may produce components that work very well individually, putting them with each other without prior factor of the entire system can create designs that don’t work, resulting in issues in the driveline that are difficult and expensive to correct.
