The number of opportunities where external charging of a vehicle parked in a residential parking space or a charging station in a predetermined period is available is counted as the number of opportunities, and the number of times of the external charging performed in the opportunities in the same predetermined period is counted as the number of times of charging. The number of times of charging is then divided by the number of opportunities to calculate and store a charging frequency. Since the charging frequency is a ratio of the number of times that the external charging was performed to the number of opportunities where the external charging is available in the predetermined period, the ratio is used as an index that can offer more accurate determination regarding an external charging utilization status. As a result, various processing to promote external charging are executed more properly.

Hybrid vehicle

A utilization index IDX is calculated based on one or more parameters (the number of times of charging/the number of trips, total battery charger connection time/total vehicle stop time, total EV traveling distance/total HV traveling distance, total EV traveling time/total HV traveling time, total EV traveling distance/total traveling distance, total EV traveling time/total traveling time, total charge amount/total fuel supply quantity) obtained based on a ratio of an EV traveling utilization level to an HV traveling utilization level or a total traveling utilization level, and the utilization index IDX is stored. Since the utilization index IDX is calculated such that as each parameter is larger, utilization of charging of a battery by a battery charger is performed more sufficiently. Accordingly, the utilization index IDX can be used as an index that offers more accurate determination regarding a utilization status of the battery charging.

A hybrid vehicle includes an engine, a fuel tank, a motor, a battery, a charger, and a notification mechanism. The battery is configured to supply electric power to the motor. The charger is configured to carry out external charging that charges the battery by use of electric power from an external power source. The notification mechanism is configured to notify, to an outside of the vehicle, information on a use index indicative of a degree of use of external charging in a predetermined time period.

Hybrid vehicle having notification mechanism

When a use index indicative of a degree of use of external charging is less than a threshold, an electronic control unit determines that the degree of use of external charging is low, and executes a charging guide control to promote the use of external charging at the time of parking at a battery charging point, such as at home or in a battery charging station, where the external charging is performable. Hereby, it is possible to promote a driver to use external charging at the time of parking at the battery charging point. As a result, the use of external charging can be promoted.

Hybrid vehicle, cooperation system, and control method for hybrid vehicle

A use index IDX indicative of a degree of use of external charging is calculated and transmitted to a vehicle external system. The vehicle external system provides a service or imposes a penalty based on the use index IDX. In a case where the degree of use of external charging is determined to be low based on the use index IDX, if the vehicle external system provides a non-preferential service or imposes a heavy penalty as compared with a case where the degree of use of external charging is determined to be high, a driver or an owner of a vehicle takes an action by which the use index is determined to indicate a high degree of use of external charging. As a result, the use of external charging can be promoted.
