Abstract
A vehicle control system includes a sensor for detecting an operating condition of a vehicle, and a control device. When the output of the sensor is normal, the control device controls an actuator in accordance with the output of the sensor. When the output of the sensor exceeds a limit value and therefore becomes abnormal, the control device controls the actuator using backup data. As the backup data, auxiliary backup data is first used, and thereafter predetermined main backup data is used. The auxiliary backup data gradually varies from a value of the output of said sensor, obtained immediately before the output of the sensor exceeds the limit value, toward the main backup data, so that the auxiliary back data becomes closer to the main backup data.
