Abstract
A vehicle drive system, that can improve drive efficiency while maintaining vehicle stability, includes a step (S3, S105) in which a switch is made from 2WD to AWD on the basis of a cumulative slip point; a step (S12, S303) in which a switch is made from 2WD to AWD on the basis of a calculated lateral G; a step (S13, S109, S111) in which a switch is made from AWD to 2WD after the step (S3 or S105) under a first switching condition; and a step (S13, S306, S308) in which a switch is made from AWD to 2WD after the step (S12 or S303) under a second switching condition. The first switching condition and the second switching condition differ from one another.
