Abstract

A vehicle control apparatus includes a condition determining unit, a mode switching controller, and a notification controller. The condition determining unit is configured to determine whether enabling conditions set to enable a switching control to an engine stop mode are satisfied. The engine stop mode stops an engine of a vehicle in a driving state. The mode switching controller is configured to perform the switching control to the engine stop mode in response to that the condition determining unit determines that the enabling conditions are satisfied. The notification controller is configured to compare a measured time value and a threshold both related to the enabling condition which the condition determining unit determines as not being satisfied. The notification controller is configured to perform, in response to that the measured time value exceeds the threshold, a control of making notification that the switching control is in a disabled state.

First claim

The invention claimed is:

1. A vehicle control apparatus comprising:
a condition determining unit configured to determine whether two or more enabling conditions are satisfied, the enabling conditions being set to enable a switching control to an engine stop mode, the switching control to the engine stop mode being a control of performing switching to the engine stop mode, the engine stop mode being a mode that stops an engine of a vehicle while the vehicle is in a driving state;
a mode switching controller configured to perform the switching control to the engine stop mode in response to that the condition determining unit determines that the enabling conditions are satisfied; and
a notification controller configured to compare a measured time value and a threshold with each other that are both related to the enabling condition, of the two or more enabling conditions, which the condition determining unit determines as not being satisfied, the notification controller being configured to perform, in response to that the measured time value exceeds the threshold, a control of making notification that the switching control to the engine stop mode is in a disabled state.

2. The vehicle control apparatus according to claim 1 , wherein the engine stop mode comprises an electric vehicle traveling mode that causes the vehicle to travel with use of power from a rotating electrical device while the engine is stopped.

3. The vehicle control apparatus according to claim 1 , wherein the notification controller is configured to perform, in response to that the measured time value exceeds the threshold, a control of making notification of the enabling condition that is determined as not being satisfied.

4. The vehicle control apparatus according to claim 2 , wherein the notification controller is configured to perform, in response to that the measured time value exceeds the threshold, a control of making notification of the enabling condition that is determined as not being satisfied.

5. The vehicle control apparatus according to claim 1 , wherein the threshold is set for each of the enabling conditions.

6. The vehicle control apparatus according to claim 2 , wherein the threshold is set for each of the enabling conditions.

7. The vehicle control apparatus according to claim 1 , wherein the measured time value comprises a measured value of time during which one, of the enabling conditions, corresponding to the measured time value is determined as not being satisfied.

8. The vehicle control apparatus according to claim 2 , wherein the measured time value comprises a measured value of time during which one, of the enabling conditions, corresponding to the measured time value is determined as not being satisfied.

9. The vehicle control apparatus according to claim 1 , wherein the measured time value comprises a measured value of time measured from a timing at which a number of the enabling condition, of the two or more enabling conditions, that remains as not being satisfied becomes one.

10. The vehicle control apparatus according to claim 2 , wherein the measured time value comprises a measured value of time measured from a timing at which a number of the enabling condition, of the two or more enabling conditions, that remains as not being satisfied becomes one.

11. The vehicle control apparatus according to claim 1 , wherein the notification controller is configured to perform, in response to notification request operation performed by a user, a control of making notification of the enabling condition which the condition determining unit determines as not being satisfied.

12. The vehicle control apparatus according to claim 2 , wherein the notification controller is configured to perform, in response to notification request operation performed by a user, a control of making notification of the enabling condition which the condition determining unit determines as not being satisfied.

13. The vehicle control apparatus according to claim 11 , wherein the notification controller is configured to perform, in a case where the notification controller detects the notification request operation, a control of making the notification of the enabling condition which the condition determining unit determines as not being satisfied, also when the measured time value does not exceed the threshold.

14. The vehicle control apparatus according to claim 12 , wherein the notification controller is configured to perform, in a case where the notification controller detects the notification request operation, a control of making the notification of the enabling condition which the condition determining unit determines as not being satisfied, also when the measured time value does not exceed the threshold.

15. The vehicle control apparatus according to claim 1 , wherein the notification controller is configured to vary the threshold in accordance with a traveling environment.

16. The vehicle control apparatus according to claim 2 , wherein the notification controller is configured to vary the threshold in accordance with a traveling environment.

17. A vehicle control apparatus comprising
circuitry configured to
determine whether two or more enabling conditions are satisfied, the enabling conditions being set to enable a switching control to an engine stop mode, the switching control to the engine stop mode being a control of performing switching to the engine stop mode, the engine stop mode being a mode that stops an engine of a vehicle while the vehicle is in a driving state,
perform the switching control to the engine stop mode in response to that the enabling conditions are determined as being satisfied,
compare a measured time value and a threshold with each other that are both related to the enabling condition, of the two or more enabling conditions, which is determined as not being satisfied, and perform, in response to that the measured time value exceeds the threshold, a control of making notification that the switching control to the engine stop mode is in a disabled state.

18. A vehicle control apparatus comprising:
a condition determining unit configured to determine whether two or more enabling conditions are satisfied, the enabling conditions being set to enable a switching control to an engine stop mode, the switching control to the engine stop mode being a control of performing switching to the engine stop mode, the engine stop mode being a mode'that stops an engine of a vehicle while the vehicle is in a driving state;
a mode switching controller configured to perform the switching control to the engine stop mode in response to that the condition determining unit determines that the enabling conditions are satisfied;
a display control unit configured to perform a display control to display on a display device of the vehicle that the switching control to the engine stop mode is in a disabled state; and
a notification controller configured to compare a measured time value and a threshold with each other that are both related to the enabling condition, of the two or more enabling conditions, which the condition determining unit determines as not being satisfied, the notification controller being configured to permit, in response to that the measured time value exceeds the threshold, a performance of the display control by the display control unit, the notification controller being configured to prohibit, in response to that the measured time value does not exceed the threshold, the performance of the display control by the display control unit.
