The variety of transmissions available for sale today has grown exponentially in the last 15 years, all while increasing in complexity. The result is that we are actually coping with a varied amount of transmitting types including manual, typical automatic, automated manual, dual clutch, continually adjustable, split power and real EV.
Until extremely recently, automotive vehicle producers largely had two types of transmitting to pick from: planetary automated with torque converter or conventional manual. Today, nevertheless, the volume of choices available demonstrates the adjustments 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 development process involved designing a transmission in isolation from the engine and the rest of the powertrain and vehicle. However, this is changing, with the limitations and complications of this method becoming more more popular, and the constant drive among manufacturers and designers to deliver optimal efficiency at decreased weight and cost.
New powertrains feature close integration of components like the prime mover, recovery systems and 
the gearbox, and in addition rely on highly advanced control systems. This is to make certain that the very best amount of efficiency and performance is delivered all the time. Manufacturers are under improved pressure to create powertrains that are completely new, different from and better than the last version-a proposition that’s made more complex by the need to integrate brand components, differentiate within the market and do it all on a shorter timescale. Engineering teams are on deadline, and the advancement process must be better and fast-paced than ever before.
Until now, the utilization of computer-aided engineering (CAE) has been the most typical way to build up drivelines. This technique involves components and subsystems designed in isolation by silos within the business that lean toward tested component-level analysis tools. While they are highly advanced equipment that enable users to extract extremely reliable and Driveline gearboxes accurate data, they are still presenting data that is collected without concern of the complete system.
While this may produce components that work nicely individually, putting them collectively 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 improve.
