摘要：It is provided about a communication system adapting for car, communication apparatus adapting for car and a communication method adapting for car that can perform data transmission under extensive range from a low speed communication to high speed communication, without generating data delay, data dropout and the like, caused by the data sending collision. A gateway and an ECU are connected to each other, in a one-to-one manner, via a communication line different from another communication line for another connection. When receiving a message, the gateway and the ECU reply a receipt response. When having a message to be sent toward the destination for replying at this replying time, the gateway and the ECU sends the receipt response onto which this message to be sent is added. When a message sending collision is generated, the gateway preferentially performs a message re-sending operation.
