Abstract
Official abstract text for this publication.
A vehicle control device includes control means for executing coasting control, in which a friction engaging element is disengaged and a rotation speed of a rotary shaft of a drive source is set at zero, when a shift range corresponds to a travel range and a coasting condition is established, and the control means executes the coasting control when the shift range is modified to a neutral range.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle control device for controlling a vehicle in which a friction engaging element is provided between a drive source and a drive wheel, comprising: a controller configured to execute coasting control to disengage the friction engaging element and set a rotation speed of a rotary shaft of the drive source at zero when a shift range corresponds to a travel range and a coasting condition is established, the shift range being selected by a driver, wherein the controller is configured to execute the coasting control when the shift range is modified to a neutral range, and execute the coasting control when the shift range corresponds to the neutral range and an accelerator pedal is depressed. 2. The vehicle control device according to claim 1 , wherein the drive source is an engine, the vehicle comprises a brake device configured to generate braking force using negative pressure of the engine when a brake pedal is depressed, and the controller is configured to halt the coasting control when the shift range corresponds to the neutral range and the brake pedal is depressed. 3. The vehicle control device according to claim 2 , wherein the controller is configured to disengage the friction engaging element during a deceleration in which an operation amount of the brake pedal is smaller than a predetermined amount, and engage the friction engaging element during a deceleration in which the operation amount of the brake pedal equals or exceeds the predetermined amount. 4. The vehicle control device according to claim 1 , wherein the controller is configured to restart the drive source when the shift range is modified from the neutral range to the travel range. 5. The vehicle control device according to claim 4 , wherein the controller is configured to engage the friction engaging element when the accelerator pedal is depressed, and disengage the friction engaging element when the accelerator pedal is not depressed. 6. The vehicle control device according to claim 5 , wherein the controller is configured to execute the coasting control when the accelerator pedal is not depressed for a predetermined time. 7. A vehicle control method for controlling a vehicle in which a friction engaging element is provided between a drive source and a drive wheel, comprising: executing coasting control to disengage the friction engaging element and set a rotation speed of a rotary shaft of the drive source at zero when a shift range corresponds to a travel range and a coasting condition is established, the shift range being selected by a driver; executing the coasting control when the shift range is modified to a neutral range; and executing the coasting control when the shift range corresponds to the neutral range and an accelerator pedal is depressed. 8. A vehicle control device for controlling a vehicle in which a friction engaging element is provided between a drive source and a drive wheel, comprising: control means for executing coasting control to disengage the friction engaging element and set a rotation speed of a rotary shaft of the drive source at zero when a shift range corresponds to a travel range and a coasting condition is established, the shift range being selected by a driver, wherein the control means executes the coasting control when the shift range is modified to a neutral range, and executes the coasting control when the shift range corresponds to the neutral range and an accelerator pedal is depressed.
