A gateway control apparatus for vehicles includes a receiver receiving travel state information sent from sensors and vehicle ECUs through interfaces, a first memory storing the travel state information, a determination unit determining occurrence of a vehicle accident or an ECU malfunction based on the travel state information, a second memory, and a controller allowing the second memory to store malfunction information of an associated ECU among the travel state information if the ECU malfunction has occurred, and allowing the first memory to store pre-accident travel state information and post-accident vehicle state information with reference to an accident occurrence time point if the vehicle accident has occurred. The gateway control apparatus enables not only data communication between the ECUs having different communication modes, but also accurate analysis of causes of the vehicle accident or the ECU malfunction. A travel information recording method of the gateway control apparatus is also disclosed.
