In an apparatus for controlling a vehicle having driving sources, a driver request torque command is calculated based on driver operation information, driving-source commands used to control the sources are calculated by dividing the request torque command among the sources, a driver request torque monitor value used to monitor an abnormality in the request torque command is calculated, driving-source monitor values used to monitor an abnormality in the driving-source commands are calculated, a driver request torque monitor margin used to determine the abnormality in the request torque command based a difference between the request torque command and monitor value is calculated, driving-source monitor margins used to determine the abnormality in the driving-source commands based on differences between the driving-source commands and monitor values are calculated based on the request torque monitor margin, and the abnormality in the driving-source commands is determined based on the driving-source monitor margins.
