Control & Electronics

Demands on transmission control systems continue to grow due to consumer expectations of ever higher levels of performance and fuel economy. In addition to this, the latest generation of powershift transmissions require even higher levels of control and actuation sophistication. Control and electronics content is an important enabler of high quality transmission design and development and thus forms an integral part of the many of Ricardo’s transmission projects.
