Abstract: A system and method for using human driving patterns to detect and correct abnormal driving behaviors of autonomous vehicles are disclosed. A particular embodiment includes: generating data corresponding to a normal driving behavior safe zone; receiving a compliant vehicle control command; comparing the compliant vehicle control command with the normal driving behavior safe zone; and issuing a warning alert if the compliant vehicle control command is outside of the normal driving behavior safe zone. Another embodiment includes modifying the compliant vehicle control command to produce a modified and validated vehicle control command if the compliant vehicle control command is outside of the normal driving behavior safe zone.
