Abstract

A vehicle status display apparatus for a hybrid vehicle includes a display configured to output a display related to a threshold indicating an engine start criterion under a traveling status using an electric motor; and a processing device. When the threshold changes, the processing device changes the display due to the change of the threshold such that a change manner of the display in a case where the threshold changes due to an operation of a vehicle'"'"'s occupant is different from a change manner of the display in a case where the threshold changes due to a factor other than the operation of the vehicle'"'"'s occupant.

Claims

1. A vehicle status display apparatus of a hybrid vehicle, comprising:

a display configured to output a display related to a threshold indicating an engine start criterion under a traveling status using an electric motor; and

a processing device configured to, when the threshold changes, change the display due to the change of the threshold such that a change manner of the display in a case where the threshold changes due to an operation of a vehicle'"'"'s occupant is different from a change manner of the display in a case where the threshold changes due to a factor other than the operation of the vehicle'"'"'s occupant.

2. The vehicle status display apparatus of claim 1, wherein the processing device makes the change manner of the display in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant slower than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

3. The vehicle status display apparatus of claim 1, wherein the display indicates a relationship between a parameter related to a drive demand amount, which is determined based on an operation amount of an accelerator pedal, and the threshold, and

the processing device makes a change manner of the relationship between the parameter and the threshold indicated by the display in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant slower than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

4. The vehicle status display apparatus of claim 2, wherein the display indicates a relationship between a parameter related to a drive demand amount, which is determined based on an operation amount of an accelerator pedal, and the threshold, and

the processing device makes a change manner of the relationship between the parameter and the threshold indicated by the display in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant slower than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

5. The vehicle status display apparatus of claim 1, wherein the display indicates a display threshold which is set based on the threshold, and

when the threshold changes, the display threshold follows the change of the threshold with a delay time, the delay time in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant being longer than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

6. The vehicle status display apparatus of claim 2, wherein the display indicates a display threshold which is set based on the threshold, and

when the threshold changes, the display threshold follows the change of the threshold with a delay time, the delay time in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant being longer than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

7. The vehicle status display apparatus of claim 3, wherein the display indicates a display threshold which is set based on the threshold, and

when the threshold changes, the display threshold follows the change of the threshold with a delay time, the delay time in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant being longer than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

8. The vehicle status display apparatus of claim 4, wherein the display indicates a display threshold which is set based on the threshold, and

when the threshold changes, the display threshold follows the change of the threshold with a delay time, the delay time in the case where the threshold changes due to the factor other than the operation of the vehicle'"'"'s occupant being longer than that in the case where the threshold changes due to the operation of the vehicle'"'"'s occupant.

9. The vehicle status display apparatus of claim 1, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

10. The vehicle status display apparatus of claim 2, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

11. The vehicle status display apparatus of claim 3, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

12. The vehicle status display apparatus of claim 4, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

13. The vehicle status display apparatus of claim 5, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

14. The vehicle status display apparatus of claim 6, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

15. The vehicle status display apparatus of claim 7, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.

16. The vehicle status display apparatus of claim 8, wherein the factor other than the operation of the vehicle'"'"'s occupant is a temperature of at least one of a battery in a hybrid system;

the electric motor which operates with power from the battery to generate a drive force for the vehicle; and

an inverter for controlling operations of the electric motor.
