Abstract

An electric motor gives regenerative braking force to a hybrid vehicle by regenerative control. A regeneration level selector selects regenerative braking force of the electric motor by a driver's operation. When an ECO mode is applied, an ECU increases the regenerative braking force selected by the regeneration level selector as compared with the time when the ECO mode is not applied.

First claim

What is claimed is:

1. A vehicle comprising:
a brake pedal operated by a first driver's operation applied to the brake pedal;
an electric motor that gives regenerative braking force to said vehicle by regenerative control;
a regeneration level selector that selects the regenerative braking force of said electric motor by a second driver's operation applied to the regeneration level selector, said regeneration level selector is configured to select one of a plurality of levels;
an ECO switch that selects an ECO mode by a third driver's operation; and
an electronic control unit that increases said regenerative braking force selected by said regeneration level selector at a time when the ECO mode is applied as compared with a time when the ECO mode is not applied.

2. The vehicle according to claim 1 , wherein
in a case where a level less than a prescribed level is selected by said regeneration level selector, said electronic control unit increases said regenerative braking force for the same level at a time when the ECO mode is applied as compared with a time when the ECO mode is not applied.

3. The vehicle according to claim 1 , wherein
when the ECO mode is applied, said electronic control unit inhibits said regeneration level selector from selecting a level less than a prescribed level.

4. The vehicle according to claim 1 , wherein
in a case where a level equal to or higher than a prescribed level is selected by said regeneration level selector, said electronic control unit sets said regenerative braking force for the same level to be identical at both of a time when the ECO mode is applied and a time when the ECO mode is not applied.

5. The vehicle according to claim 1 , wherein, when said ECO mode is applied and when a speed of said vehicle is equal to or higher than a first prescribed value, said electronic control unit decreases said regenerative braking force as said speed increases.

6. The vehicle according to claim 1 , wherein, when said ECO mode is applied and when a speed of said vehicle is equal to or less than a second prescribed value, said electronic control unit decreases said regenerative braking force as said speed decreases.

7. A vehicle comprising:
a brake pedal operated by a first driver's operation applied to the brake pedal;
an electric motor that gives regenerative braking force to said vehicle by regenerative control;
a regeneration level selector that selects the regenerative braking force of said electric motor by a second driver's operation, applied to the regeneration level selector, said regeneration level selector configured to select one of a plurality of levels;
an ECO switch that selects an ECO mode by a third driver's operation; and
an electronic control unit that inhibits said regeneration level selector from selecting a level less than a prescribed level when the ECO mode is applied.

8. The vehicle according to claim 7 , wherein in a case where a level equal to or higher than the prescribed level is selected by said regeneration level selector, said electronic control unit sets said regenerative braking force for the same level to be identical at both of a time when the ECO mode is applied and a time when the ECO mode is not applied.

9. The vehicle according to claim 7 , wherein, when said ECO mode is applied and when a speed of said vehicle is equal to or higher than a first prescribed value, said electronic control unit decreases said regenerative braking force as said speed increases.

10. The vehicle according to claim 7 , wherein, when said ECO mode is applied and when a speed of said vehicle is equal to or less than a second prescribed value, said electronic control unit decreases said regenerative braking force as said speed decreases.
