Abstract: The present invention relates to a gateway device, a network system and a data converting method using a plurality of network protocols different from each other. A gateway device includes a first communication controller connected to first device via a first bus in accordance with a first network protocol to exchange data with the first device in accordance with the first network protocol, a second communication controller connected to second device via a second bus in accordance with a second network protocol different from the first network protocol to exchange the data with the second device in accordance with the second network protocol, and a control unit interconverting the data in accordance with the first network protocol and the data in accordance with the second network protocol into each other so that the data is exchanged between the first device and the second device.

Abstract: The present invention relates to an in-vehicle networks system and a method of controlling the same. The in-vehicle network system includes a first actuator and second actuators; shared sensors outputting a sensing value according to a sensing result; a first sub ECU controlling the driving of the first actuator and outputting a first sub sensing value corresponding to the sensing value from the shared sensors; a second sub ECU controlling the driving of the first actuator and outputting a second sub sensing value corresponding to the sensing value from the shared sensors; and a main ECU communicating with the first sub ECU and the second sub ECU according to a TDMA-based communication protocol, and determining that any one of the first ECU and the second ECU is abnormal in case that a difference between the first sensing value and the second sensing value is out of an error tolerance.
