Abstract

A control system of a vehicle includes an automatic transmission provided with a plurality of friction engagement elements changeable between engaged and disengaged states, and configured to form a plurality of gear stages by changing a combination of three friction engagement elements to be selectively engaged among the friction engagement elements, and a controller which controls the change between the engaged and disengaged states of each friction engagement element. The controller performs a neutral control in which, for setting the automatic transmission to a neutral state in which a driving force of a drive source is not transmitted to driving wheels, while two of the three friction engagement elements engaged when forming each gear stage are kept engaged, the remaining one of the three friction engagement element is disengaged. The two friction engagement elements engaged during the neutral control are common in at least two adjacent gear stages.
