Abstract
Official abstract text for this publication.
A vehicle control device for controlling a vehicle includes a drive source and an automatic transmission connected to the drive source and including a variator. The vehicle control device includes: a first control unit configured to execute a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state if a during-travel drive source stop condition is satisfied; and a second control unit configured to execute a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state if a during-travel drive source stop release condition is satisfied. The second control unit executes the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control if the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied.

The invention claimed is: 1. A vehicle control device for controlling a vehicle with a drive source and an automatic transmission connected to the drive source and including a variator, comprising: a first control unit configured to execute a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state when a during-travel drive source stop condition is satisfied; and a second control unit configured to execute a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state when a during travel drive source stop release condition is satisfied, wherein the second control unit is configured to execute the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control when the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied, and the second control unit is configured to downshift the variator from a target speed ratio during the rotation synchronization control, after the rotation synchronization control. 2. A vehicle control method for controlling a vehicle with a drive source and an automatic transmission connected to the drive source and including a variator, comprising: executing a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state when a during-travel drive source stop condition is satisfied; executing a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state when a during-travel drive source stop release condition is satisfied; executing the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control when the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied; and downshifting the variator from a target speed ratio during the rotation synchronization control, after the rotation synchronization control. 3. A vehicle control device for controlling a vehicle with a drive source and an automatic transmission connected to the drive source and including a variator, comprising: first control means for executing a during-travel drive source stop control for stopping the drive source and shifting the automatic transmission in a neutral state when a during-travel drive source stop condition is satisfied; and second control means for executing a during-travel drive source stop release control for shifting the automatic transmission in a power transmission state via a rotation synchronization control in the automatic transmission set in the neutral state when a during-travel drive source stop release condition is satisfied, wherein the second control means executes the rotation synchronization control with the variator downshifted from a speed ratio during the during-travel drive source stop control when the during-travel drive source stop release condition accompanied by a downshifting request of the variator is satisfied, and the second control unit downshifts the variator from a target speed ratio during the rotation synchronization control, after the rotation synchronization control.
