Electrification of the BMW Group’s Pruefcubing process helped to overcome the limitation of using non-functional “dummy” control units for components such as the electrically extendable door handles that were included on several models of the Neue Klasse line. Through evaluating the feasibility of three different methods of integrating electrical components into the mock-up vehicles, the BMW Group determined that the Direct Node Actuation method was the most economical and autonomous means of creating the “Functional Islands” required within these static mock-ups. The implementation of an STM32F446RE microcontroller and an MCP2004A transceiver into the Pruefcubing mock-up vehicles permitted those static models to emulate the master control unit of the vehicle. The implementation of these components allowed the mock-up vehicles to operate their door handles in accordance with the specifications of the LIN 2.2 protocol, earning the implementation an “Outstanding” rating from the company. Overall, this implementation permitted for electrical and electronic (E/E) defects to be resolved three years prior to when the affected vehicles would go into production, reducing the costs that would otherwise be associated with correcting those defects during production.
