All of the transmissions available for sale today has grown exponentially within the last 15 years, all while increasing in complexity. The effect is that we are now dealing with a varied quantity of tranny types including manual, typical automatic, automated manual, dual clutch, continuously adjustable, split power and real EV.
Until extremely recently, automotive vehicle manufacturers largely had two types of transmitting to pick from: planetary automatic with torque converter or conventional manual. Today, however, the volume of choices available demonstrates the adjustments seen over the industry.
That is also illustrated by the many various kinds of vehicles now being produced for the marketplace. And not merely conventional vehicles, but also all electric 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. However, that is changing, with the restrictions and complications of the method becoming more more popular, and the constant drive among producers 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 also rely on highly sophisticated control systems. That is to assure that the very best degree of efficiency and efficiency is delivered all the time. Manufacturers are under improved pressure to create powertrains that are completely new, different from and much 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 it all on a shorter timescale. Engineering teams are on deadline, and the advancement process needs to be better and fast-paced than ever before.
Until now, the utilization 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 organization that lean toward verified component-level analysis tools. While they are highly advanced tools that enable users to extract very reliable and accurate data, they remain presenting data that’s collected without consideration of the whole system.
