Patent ID: 7242109

Claim:
Bus system, containing a bus line having a first section ( 12 ), to which first electronic devices ( 26 – 30 ) can be connected, and a second section ( 14 ) to which second electronic devices ( 32 – 34 ) can be connected, wherein at least one electronic device ( 36 ) can be connected to the bus line at a separable interface ( 38 ) between the first section ( 12 ) and the second section ( 14 ), wherein the interface ( 38 ) contains a first connection ( 42 ) and a second connection ( 44 ) of a motor vehicle, and wherein the first connection ( 42 ) is connected to the first section ( 12 ) of the bus line and the second connection ( 44 ) is connected to the second section ( 14 ) of the bus line, and a bypass device ( 40 ) including an electronically controlled switch ( 46 ), wherein the electronically controlled switch automatically produces a connection between the first section ( 12 ) of the bus line and the second section ( 14 ) of the bus line if the electronic device ( 36 ) is disconnected from the interface ( 38 ) to prevent an interruption of the bus line, and wherein the first and second sections ( 12 , 14 ) of the bus line are connected through the interface ( 38 ) when the electronic device ( 36 ) is connected to the interface ( 38 ), the connection between the first section ( 12 ) of the bus line and the second section ( 14 ) of the bus line being maintained both if the electronic device ( 36 ) disconnected from or connected to the interface and wherein the bus line comprises a CAN bus transmitting electrical signals.
