Abstract

A hybrid vehicle includes an engine, a rotary electric machine, an electric power storage device, an electric power generation device, a switch, and an ECU. The switch is a switch operated by a user when the user requires recovery control to be executed or stopped. The recovery control is control for increasing the electric power storage amount of the electric power storage device by using the electric power generation device. The ECU is configured to select any one of a plurality of control modes that include a charge sustaining mode and a charge depleting mode, and control the hybrid vehicle in accordance with the selected control mode. The ECU is configured to select the charge depleting mode when the recovery control is requested to be stopped by using the switch during the execution of the recovery control.

First claim

What is claimed is:

1. A hybrid vehicle comprising:
an engine;
a rotary electric machine configured to be a driving source for the hybrid vehicle;
an electric power storage device configured to supply electric power to the rotary electric machine;
an electric power generation device configured to generate electric power for charging the electric power storage device by using the power of the engine;
a switch for a user to operate when the user requires recovery control to be executed or stopped, the recovery control being control for increasing an electric power storage amount of the electric power storage device to an upper limit value by using the electric power generation device; and
an ECU configured to
(a) select any one of a plurality of control modes, the control modes including a charge sustaining mode and a charge depleting mode, the charge sustaining mode being a mode in which a reduction in the electric power storage amount is suppressed, and the charge depleting mode being a mode in which the electric power of the electric power storage device is consumed,
(b) control the hybrid vehicle in accordance with the selected control mode, and
(c) select the charge depleting mode when the recovery control is requested to be stopped by using the switch during the execution of the recovery control.

2. The hybrid vehicle according to claim 1 wherein
the ECU selects the charge sustaining mode when the electric power storage amount reaches the upper limit value as a result of the execution of the recovery control.

3. The hybrid vehicle according to claim 1 wherein
the ECU selects the charge sustaining mode when the recovery control is requested to be stopped by using the switch after the electric power storage amount reaches the upper limit value as a result of the execution of the recovery control.

4. The hybrid vehicle according to claim 1 wherein
the ECU selects any one of the charge sustaining mode and the charge depleting mode depending on a malfunctioning part of the hybrid vehicle when the electric power storage amount reaches the upper limit value during the execution of the recovery control and the malfunctioning part is present in the hybrid vehicle.

5. A hybrid vehicle comprising:
an engine;
a rotary electric machine configured to be a driving source for the hybrid vehicle;
an electric power storage device configured to supply electric power to the rotary electric machine;
an electric power generation device configured to generate electric power for charging the electric power storage device by using the power of the engine;
a switch configured to transmit a signal when the switch is operated, the switch being a switch operated by a user; and
an ECU configured to
(a) select any one of a plurality of control modes,
(b) control the hybrid vehicle in accordance with the selected control mode, the control modes including a charge sustaining mode and a charge depleting mode, the charge sustaining mode being a mode in which a reduction in the electric power storage amount is suppressed, and the charge depleting mode being a mode in which the electric power of the electric power storage device is consumed,
(c) receive the signal,
(d) execute a recovery control when the signal is a first signal, the first signal being a signal for requesting the recovery control to be executed, the recovery control being control for increasing an electric power storage amount of the electric power storage device to an upper limit value,
(e) stop the recovery control when the signal is a second signal, the second signal being a signal for requesting the recovery control to be stopped, and
(f) select the charged depleting mode when the second signal is received during the execution of the recovery control.

6. A hybrid vehicle comprising:
an engine;
a motor-generator configured to supply electric power by using the power of the engine;
an electric power storage device configured to store the electric power generated by the motor-generator; and
an electric control unit configured to select any one of a plurality of control modes, the control modes including
i) a charge sustaining mode sustaining an amount of the electric power stored in the electric power storage device,
ii) a charge depleting mode consuming the electric power stored in the electric power storage device, and
iii) a charge increasing mode increasing the amount of the electric power stored in the electric power storage device, wherein

the electronic control unit is configured to select the charge depleting mode when cancelling the charge increasing mode is requested by a user during the charge increasing mode being selected.

7. The hybrid vehicle according to claim 6 , wherein
the electronic control unit is configured to select the charge sustaining mode when increasing the amount of the electric power stored in the electric power storage is completed during the charge increasing mode being selected.

8. The hybrid vehicle according to claim 6 , wherein
the electronic control unit is configured to select the charge sustaining mode when increasing the amount of the electric power stored in the electric power storage is completed and canceling the charge increasing mode is requested during the charge increasing mode being selected.

9. The hybrid vehicle according to claim 6 , wherein
the electronic control unit is configured to select the charge sustaining mode or the charge depleting mode in accordance with a malfunction of the hybrid vehicle when increasing the amount of the electric power stored in the electric power storage is completed and the hybrid vehicle has the malfunction.
