摘要

A control system of a vehicle includes an engine, a continuously variable transmission, drive wheels, a clutch, and an electronic control unit. The electronic control unit is configured to release the clutch and stop the engine when a predetermined execution condition is satisfied during traveling, such that the vehicle performs coasting. The electronic control unit is configured to keep the continuously variable transmission at a speed ratio established at start of the coasting, during the coasting of the vehicle. The electronic control unit is configured to restart the engine that has been stopped and perform downshift of the continuously variable transmission, when a predetermined return condition is satisfied during the coasting. The electronic control unit is configured to engage the clutch after the downshift is started, such that the vehicle returns from the coasting.
