Each of a plurality of electronic control units (i.e., ECUs) of a vehicle control system has a memory for recording data regarding a system operation condition of the vehicle control system. When one of the ECUs detects an occurrence of a predetermined abnormal event, that ECU records data regarding the system operation condition of the vehicle control system, which is held by that ECU, in the memory of that ECU. Further, the detecting ECU notifies the other ECUs of the occurrence of the predetermined abnormal event. Accordingly, each of the remaining ECUs records data regarding the system operation condition of the vehicle control system held by each of them to its memory. In such manner, even if multiple ECUs are installed as the vehicle control system, a vehicular data recording apparatus is enabled to record required data at a time of occurrence of a predetermined event. |
