Abstract
Mechatronic assemblies include electronic control units (ECUs) in general. These ECUs provide the functionalities of the assemblies via their firmware. In premium class vehicles there are up to 100 ECUs. During the entire product life cycle it is indispensable for manufactures and customer service to communicate with the implemented microcontroller. Currently communication works throughout service- or internal installed interfaces. Therefore it is necessary to open the case or to use a suitable plug for a successful data exchange. To enable a wireless communication, the new (service-) interface Radio Frequency Communication (RFCo) will be developed. Additional it will be possible to supply the microcontroller in the ECU wireless with voltage, which means wires and plugs are no longer required for communication. Besides the space saving, the RFCo interface enables a lot of innovative possibilities. For example, it will be possible to install a country-specific firmware on packed mechatronic assemblies before their distribution. Consequently only assemblies with the latest firmware will be delivered and variant diversities in production processes can be reduced. This results in a reduction of process times and production costs, while the customer satisfaction increases simultaneously.
