Abstract: A vehicle control device includes a controller configured to allow cranking of an engine by increasing clutch torque at a time a deceleration request is detected during free running in which a vehicle is allowed to run in a state in which a clutch is disengaged and the engine is stopped, and make an increasing rate of the clutch torque larger at a time a negative pressure of a brake booster is small than at a time the negative pressure of the brake booster is large.

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.
