Virtual Product Development & Transmission Control

Transmissions today are created on a 3D screen

Transmissions today are created on a 3D screen, just like all the other components of an automobile. This virtual development has proven to be cost-effective and fast.

At Transmission Systems, the foundations for the quality, material costs, noise generation or durability of our transmissions are created during this early stage of the engineering process.

Virtual product and process development requires a huge amount of data and, above all, efficient management of this information. After all, we have gathered expertise over generations of engineers.

This makes us an important development partner for automobile manufacturers from all over the world: our digital product intelligence strengthens the competitiveness of our customers.

Perfect harmony between electronics, hydraulics and mechanics

With automated transmissions, the driver steps into the background and the technology becomes responsible for the operating the clutch and gear shifting. These functions are taken over by actuators (mechanical or hydraulic converters), which, interacting with sensors, engage the desired gear.

Our transmission control specialists programme a mechatronic transmission control system that determines when and how a transmission shifts. Hence, at this point in the development process, decisions are made regarding the tuning of a transmission and, therefore, the driving behaviour of a car: sporty or comfortable.

At Transmission Systems, a transmission control is initially developed as a virtual model, even the tuning is virtually modelled. Then, our engineers are able to optimise the interaction between engine control, transmission functions and vehicle electronics – just like solving an equation with several unknowns. Next, using rapid prototyping tools, the first real model is created. The control functions previously simulated are tested in practice and, if necessary, improved.

The transmission will function optimally and the shift process will be barely noticeable only when the electronics, hydraulics and mechanics are in perfect harmony. Only then we proceed to the next step.
