    摘要： To provide a communication system and a communication method that are capable of determining with a simple configuration the validity of a message that is communicated with the communication system, a plurality of ECUs is connected in the communication system to a communication bus, allowing communication of messages. A communication interval, which is defined for each message being communicated, is set for each ECU. The ECU that transmits the message transmits the message on the basis of the defined communication interval. The ECU that receives the transmitted message detects the communication interval of the received message, and determines the validity of the received message on the basis of a comparison between the detected communication interval and the defined communication interval.

    摘要： A plurality of in-vehicle control apparatuses (100) and a DLC (200) connected to a vehicle network each include a frame monitoring unit (131). The frame monitoring units (131) detect simultaneous transmission of a plurality of communication data having a shared CAN ID by monitoring an error frame transmitted to the vehicle network. The plurality of in-vehicle control apparatuses (100) and the DLC (200) also each include a control determination unit (132) and a transmission/reception control unit (133) that execute adjustment processing to adjust the plurality of communication data having the shared CAN ID when simultaneous transmission of the communication data is detected.
