All of the transmissions available for sale today is continuing to grow exponentially within the last 15 years, all while increasing in complexity. The effect is certainly that we are now dealing with a varied number of tranny types including manual, standard automatic, automated manual, dual clutch, consistently adjustable, split power and real EV.
Until very recently, automotive vehicle manufacturers largely had two types of transmitting to select from: planetary automatic with torque converter or conventional manual. Today, however, the volume of choices available demonstrates the changes seen over the industry.
That is also illustrated by the many various kinds of vehicles now being manufactured for the market. And not only conventional vehicles, but also all electrical and hybrid automobiles, with each type requiring different driveline architectures.
The traditional advancement process involved designing a transmission in isolation from the engine and the rest of the powertrain and vehicle. However, that is changing, with the limitations and complications of this method becoming more widely recognized, and the continuous drive among producers and designers to provide optimal efficiency at reduced weight and cost.
New powertrains feature close integration of elements like the primary mover, recovery systems and the gearbox, and also rely on highly advanced control systems. That is to make certain that the best amount of efficiency and performance is delivered all the time. Manufacturers are under improved pressure to create powertrains that are brand new, different from and much better than the last version-a proposition that’s made more complex by the need to integrate brand components, differentiate within the marketplace and do everything on a shorter timescale. Engineering teams are on deadline, and the advancement process needs to be more efficient and fast-paced than ever before.
Until now, the use of computer-aided engineering (CAE) has been the most typical way to develop drivelines. This process involves components and subsystems designed in isolation by silos within the business that lean toward verified component-level analysis equipment. While they are highly advanced equipment that enable users to extract extremely dependable and accurate data, they are still presenting data that’s collected without thought of the complete system.
