Abstract

A travel control device includes: an engine; an automatic transmission including a plurality of engagement elements and a rotary element, the automatic transmission being configured to block power transmission between the engine and a drive wheel of a vehicle and set a transmission gear ratio in accordance with an engagement element to be engaged out of the plurality of engagement elements; and a controller configured to perform free-running by blocking power transmission between the engine and the drive wheel while traveling at a predetermined transmission gear ratio and stopping the engine. The controller is configured to increase speed of a rotary element inside the automatic transmission during the free-running, and start the engine at a time speed of the engine becomes higher than a predetermined speed at a time of returning from the free-running.
