Hybrid vehicle, controller for hybrid vehicle, and control method for hybrid vehicle

A controller for a hybrid vehicle,

• the hybrid vehicle including an engine, a motor, and a power storage device that is connected to the motor,
• the controller comprising:
• an electronic control unit configured to,
• i) when a condition a) is satisfied, execute power storage capacity decreasing control in a current trip and execute power storage capacity recovering control in a next trip, and
• ii) limit execution of the power storage capacity decreasing control in the current trip when the condition a) and a condition b) are both satisfied,
• a) parking at a predetermined point is predicted, and
• b) when the next trip is started at the predetermined point, heavy-load traveling with a load heavier than a predetermined load is predicted to be performed within a predetermined period after a start of the next trip,
• the power storage capacity decreasing control being control of controlling the engine and the motor such that a power storage capacity of the power storage device is lower when the condition a) is satisfied than when the condition a) is not satisfied,
• the power storage capacity recovering control being control of controlling the engine and the motor such that the power storage capacity of the power storage device is recovered when the engine operates, and
• the predetermined period being at least one period of a period in which a predetermined time elapses and a period in which the hybrid vehicle travels a predetermined distance.

A control method for a hybrid vehicle,

• the hybrid vehicle including an engine, a motor, a power storage device that is connected to the motor, and an electronic control unit,
• the control method comprising:
• i) when a condition a) is satisfied, executing, by the electronic control unit, power storage capacity decreasing control in a current trip and executing, by the electronic control unit, power storage capacity recovering control in a next trip, and
• ii) limiting, by the electronic control unit, execution of the power storage capacity decreasing control in the current trip when the condition a) and a condition b) are both satisfied,
• a) parking at a predetermined point is predicted, and
• b) when the next trip is started at the predetermined point, heavy-load traveling with a load heavier than a predetermined load is predicted to be performed within a predetermined period after a start of the next trip,
• the power storage capacity decreasing control is control of controlling the engine and the motor such that a power storage capacity of the power storage device is lower when the condition a) is satisfied than when the condition a) is not satisfied,
• the power storage capacity recovering control is control of controlling the engine and the motor such that the power storage capacity of the power storage device is recovered when the engine operates, and
• the predetermined period is at least one period of a period in which a predetermined time elapses and a period in which the hybrid vehicle travels a predetermined distance.
