Abstract
Official abstract text for this publication.
A control device for a vehicle controlling the vehicle including a driving source and an automatic transmission coupled to the driving source and includes a power transmission mechanism including a forward engaging element. The control device for the vehicle includes a first control unit configured to execute a driving-source-stop-while-traveling control that stops the driving source and brings the automatic transmission into a neutral state when a driving-source-stop-while-traveling condition for stopping the driving source while traveling is satisfied and a second control unit configured to engage the forward engaging element on the basis of input and output rotation speeds of the power transmission mechanism after a driving-source-stop-while-traveling cancellation condition is satisfied.
First claim
Opening claim text (preview).
The invention claimed is: 1. A control device for a vehicle, the control device for the vehicle controlling the vehicle including a driving source and an automatic transmission coupled to the driving source, the automatic transmission including a power transmission mechanism including a forward engaging element, the control device for the vehicle comprising: a controller configured to: execute a driving-source-stop-while-traveling control when a driving-source-stop-while-traveling condition for stopping the driving source while traveling is satisfied, the driving-source-stop-while-traveling control stopping the driving source and bringing the automatic transmission into a neutral state; engage the forward engaging element when input and output rotation speeds of the power transmission mechanism are synchronized after a driving-source-stop-while-traveling cancellation condition is satisfied; and execute a feedback control, the feedback control fully engaging the forward engaging element, when an actual pressure of a piston pressure receiving chamber of the forward engaging element is detected to be a predetermined value or more, wherein the controller inhibits the execution of the feedback control when the driving-source-stop-while-traveling cancellation condition is satisfied. 2. The control device for the vehicle according to claim 1 , wherein the controller supplies a standby pressure to the forward engaging element after the driving-source-stop-while-traveling cancellation condition is satisfied and before the forward engaging element is fully engaged. 3. The control device for the vehicle according to claim 1 , wherein the automatic transmission includes a variator, and the controller engages the forward engaging element in a state where a speed ratio of the variator is on a high side. 4. The control device for the vehicle according to claim 1 , wherein the controller executes the driving-source-stop-while-traveling control when a brake is off. 5. A control method for a vehicle, the control method for the vehicle controlling the vehicle including a driving source and an automatic transmission coupled to the driving source, the automatic transmission including a power transmission mechanism including a forward engaging element, the control method for the vehicle comprising: executing a driving-source-stop-while-traveling control when a driving-source-stop-while-traveling condition for stopping the driving source while traveling is satisfied, the driving-source-stop-while-traveling control stopping the driving source and bringing the automatic transmission into a neutral state; engaging the forward engaging element when input and output rotation speeds of the power transmission mechanism are synchronized after a driving-source-stop-while-traveling cancellation condition is satisfied; executing a feedback control, the feedback control fully engaging the forward engaging element, when an actual pressure of a piston pressure receiving chamber of the forward engaging element is detected to be a predetermined value or more; and inhibiting the execution of the feedback control when the driving-source-stop-while-traveling cancellation condition is satisfied. 6. A control device for a vehicle, the control device for the vehicle controlling the vehicle including a driving source and an automatic transmission coupled to the driving source, the automatic transmission including a power transmission mechanism including a forward engaging element, the control device for the vehicle comprising: first control means for executing a driving-source-stop-while-traveling control when a driving-source-stop-while-traveling condition for stopping the driving source while traveling is satisfied, the driving-source-stop-while-traveling control stopping the driving source and bringing the automatic transmission into a neutral state; second control means for engaging the forward engaging element when input and output rotation speeds of the power transmission mechanism are synchronized after a driving-source-stop-while-traveling cancellation condition is satisfied; and third control means for executing a feedback control, the feedback control fully engaging the forward engaging element, when an actual pressure of a piston pressure receiving chamber of the forward engaging element is detected to be a predetermined value or more, wherein the third control means inhibit the execution of the feedback control when the driving-source-stop-while-traveling cancellation condition is satisfied.
