  • Publication number: 20190322181
    Abstract: 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.

  • Patent number: 10407081
    Abstract: 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.

  • Patent number: 10391866
    Abstract: An electrically-driven vehicle includes: a rotary electric machine; an electric power storage device; a communication device communicable with a server on the outside of the electrically-driven vehicle; and an electronic control unit configured to control external charging in which the electric power storage device is charged by using electric power that is supplied from a power feeding device on the outside of the electrically-driven vehicle. The electronic control unit acquires information from the server, the information indicating a degree of tightness of electricity supply-demand balance at a destination of the electrically-driven vehicle, and then prohibits execution of external charging promotion control for urging a user to perform the external charging at the destination in the case where the acquired information indicates that the degree of the tightness is higher than a reference level.

  • Patent number: 10328816
    Abstract: 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.

  • Patent number: 10328930
    Abstract: A cruising distance coefficient is set that is smaller than a value of 1 and that becomes smaller as a use index indicating a degree of use of external charging gets smaller, and a cruising distance is calculated by multiplying a fuel quantity by the set cruising distance coefficient and a fuel consumption coefficient. Then, a display cruising distance is calculated by subtracting from the cruising distance a value obtained by subtracting a set-time travel distance Lset, obtained when the cruising distance is calculated, from a travel distance from a travel distance meter, and the calculated display cruising distance is displayed on a display device in front of a driver's seat.

  • Patent number: 10311653
    Abstract: 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.
