In a vehicle control system, when an electronic engine control unit (6), an electronic control unit for an automatic transmission (7) or an electronic brake control unit (8) occurs, important information that requires urgent response by any of the other electronic control units becomes the important information Transfer information via a communication line for important information (L1) directly to the corresponding electronic control unit without going through an electronic management control unit (10). A control device in the electronic control unit therefore receives the important information and immediately controls the corresponding component (a motor (2), an automatic transmission (4) or brakes (5), based on the important information. |
