Processor unit for a data-processing-aided electronic control system in a motor vehicle
First Claim
Patent Images
1. A vehicle network structure with a control unit having a processor unit for a data processing-aided electronic control system;
- a gateway with a motor vehicle communication interface unit including at least two communication interfaces to interface with at least a first vehicle databus and a second vehicle databus, wherein said first databus has a first transmitting frequency and is directly connected to at least one additional control unit of the vehicle said second databus is one of KIN bus, a CAN bus, a diagnostic bus or a telematic bus and is directly connected to at least another one additional control unit of the vehicle, said second databus having a second transmitting frequency wherein incoming messages (Na) from one of said first and second databuses are transmitted at a frequency (fa′
) which differs from a receiving frequency (fa) of the other one of said first and second databuses, wherein the vehicle communication interface unit is a separate structural hardware component from said processor unit and wherein the vehicle communication interface unit includes a bandwidth adapter to convert said incoming messages from said one of said first and second databus to another one of said first and second databus;
said vehicle communication interface unit further comprising a bridge and a router unit for converting individual ones of received frames from one of said at least two communication interfaces to another one of said at least two communication interfaces; and
means for modifying said received frames.
