E/E-architecture

In the Visio.M project the E/E-architecture of the EV is improved by increasing the energy efficiency and safety. Additionally, the vehicle is connected with the backend in order to provide cloud services. For this reason a mobile router (from Continental) is integrated in the vehicle. This mobile router serves as a central communication unit which enables to change smoothly between different mobile radio standards like LTE, UMTS and WLAN – according to a predefined strategy considering aspects such as highest bandwidth and signal quality. Thus, thanks to this router, the best connection to cloud services can be reached at any times without the active intervention of the driver.

In cooperation with the “Innovationszentrum für Mobilität und gesellschaftlichen Wandel” (InnoZ, Innovation Centre for Mobility and Social Change) innovative services are planned and realised that benefit from this mobile interaction. These services should help to make urban electromobility more attractive. Current cloud services regarding traffic flow, topography and weather conditions enable, for example, to calculate the route with the lowest level of energy consumption, to define exactly the remaining range and to schedule the charging processes with the driver’s needs: in order to ensure a safe way back the navigation could take a bearing on free charging units and reserve them for the estimated arriving time. In addition to this, the charging process of the electric vehicles can be controlled per remote with smartphones.

An innovative and low energy consuming IT platform from Texas Instruments disposes of the necessary computing efficiency. As a human machine interface it is combined with a touch-based operation concept. Thus, value-added services in the field of car sharing, sustainability, entertainment and safety are developed within the Visio.M project.

The Lehrstuhl für Fahrzeugtechnik (Institute of Automotive Technology) and the Lehrstuhl für Wirtschaftsinformatik (Institute of Business Information Technology) from the Technische Universität München work on this research field.
