VEHICLE-SPECIFIC NETWORK COMMUNICATION MANAGEMENT DEVICE AND COMMUNICATION MANAGEMENT METHOD

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.
