Abstract

A hybrid vehicle control device is provided that is capable of controlling a drive source according to a travel plan. The hybrid vehicle control device is configured to be mounted in a hybrid vehicle including a drive source having an engine and a motor/generator, and a navigation system that acquires travel environment information of a planned travel route. The control device is configured such that, upon selection of a “travel plan mode”, which controls the drive source according to a travel plan set for low fuel travel based on travel environment information acquired from the navigation system in the absence of the selection of an “eco-mode”, which controls the drive source to prioritize fuel efficiency over power performance, the selection of the “travel plan mode” is linked with a setting operation for the “eco-mode”.

Claims

1. A hybrid vehicle control device configured to be mounted in a hybrid vehicle having a drive source that includes an engine and a motor, and a navigation system that acquires travel environment information on a planned travel route, and comprising:

a drive source controller that carries out control of the drive source in accordance with a driving mode of the hybrid vehicle, wherein

the hybrid vehicle comprises, as the driving modes, a travel plan mode that controls the drive source in accordance with a travel plan that is set for low fuel consumption travel based on the travel environment information, and an eco-mode that controls the drive source to prioritize fuel efficiency over power performance, and

the drive source controller is configured to link a selection of the travel plan mode with a setting operation of the eco-mode, upon the travel plan mode being selected in a state in which the eco-mode is not selected, and

the drive source controller is configured to automatically set the eco-mode upon selection of the travel plan mode when the selection of the travel plan mode is linked with the setting operation of the eco-mode.

2. The hybrid vehicle control device according to claim 1, wherein

the drive source controller includes driver characteristic information in the travel environment information that is used when setting the travel plan.

3. (canceled)

4. A The hybrid vehicle control device configured to be mounted in a hybrid vehicle having a drive source that includes an engine and a motor, and a navigation system that acquires travel environment information on a planned travel route, and comprising:

a drive source controller that carries out control of the drive source in accordance with a driving mode of the hybrid vehicle, wherein

the hybrid vehicle comprises, as the driving modes, a travel plan mode that controls the drive source in accordance with a travel plan that is set for low fuel consumption travel based on the travel environment information, and an eco-mode that controls the drive source to prioritize fuel efficiency over power performance,

the drive source controller being configured to link a selection of the travel plan mode with a setting operation of the eco-mode, upon the travel plan mode being selected in a state in which the eco-mode is not selected, and

the drive source controller is configured to induce the driver to set the eco-mode upon selection of the travel plan mode upon the selection of the travel plan mode being linked with the setting operation of the eco-mode.

5. The hybrid vehicle control device according to claim 4, wherein

the drive source controller includes driver characteristic information in the travel environment information that is used when setting the travel plan.
