- 3. 3 Vector Solutions for … Facts and Figures Electronic networking in the aerospace industry, primarily in non-flight critical applications (galley, doors, seats, ...) Vector is actively participating in the definition of the AUTOSAR standard. MICROSAR is the Vector AUTOSAR solution, also for ISO 26262. Embedded software, tools and consulting for protecting vehicle functions against cyber attacks Development and application of all automotive bus systems from specification to testing Reliable networking and calibration of sensors for driver assistance systems and automated driving ECUs for prototypes and small production runs: flexible and universal in automotive/commercial vehicles, agriculture and special machines Battery management of future-oriented electric/ hybrid vehicles as well as charging management and communication of charging stations Development of systems for wireless communication between vehicles, with infrastructure and with back ends ECU development AUTOSAR, safety Avionics networking Automotive cybersecurity Automotive Ethernet, FlexRay, CAN, LIN, MOST Advanced driver assistance systems (ADAS) E-mobility Automotive Connectivity (Automotive OTA & Car2x/V2X)
- 5. 5 Applications for Electrical Charging of Private Vehicles Facts and Figures We don't want to stop for charging, we want to charge when we stop anyway. The shorter we park the car, the faster we want to charge. Destination charging En-route charging Necessity charging Public charge points along travel routes e.g. motorways or at charging hubs In-between charging Public charge points at supermarkets, shopping centers or curb side Home & work charging Private and semi-public charge points for longer or overnight charging sessions DC charging today: still mostly AC charging Approx. 10 % Approx. 90 %
