A vehicle control system includes electronic controllers and first and second communications networks. The electronic controllers control a vehicle including an internal combustion engine and a drive motor. The electronic controllers include a management controller to manage travel control of the vehicle and a motor drive controller to control the drive motor. The first and second communications networks connect the electronic controllers together. The electronic controllers communicate via the first and second communications networks. The motor drive controller is configured to stop the drive motor when it is determined that a fault has occurred in the first communications network and configured to transmit information indicating that the fault has occurred in the first communications network to the management controller via the second communications network. The management controller is configured to control the electronic controllers not to communicate via the first communications network in response to the information.
