  • Patent number: 11529994
    Abstract: A vehicle control system installed on a vehicle includes: an automatic steering control device configured to execute automatic steering control that determines a steering angle command value and controls steering of the vehicle such that an actual steering angle follows the steering angle command value; a stop state detection device configured to detect a stop state where the vehicle is stopped; and an override detection device configured to detect an override operation by a driver of the vehicle. When the override operation is detected in the stop state, the automatic steering control device prohibits variation in the actual steering angle due to the automatic steering control, until the vehicle starts moving.
