Control device, control method, and electrical vehicle

A control method for an electrical vehicle that includes an internal combustion engine, a storage battery, and an electric motor driven by supply of electric power from the storage battery, and travels in a plurality of traveling modes in which usage amounts of electric power of the storage battery are different, the control method comprising

• creating a travelling plan in which any one of the plurality of travelling modes is assigned to each traveling section of a scheduled traveling route from a current position of the electrical vehicle to a destination, and controlling the travelling mode of the electrical vehicle based on the created travelling plan,
• wherein, when the scheduled traveling route is changed during travelling of the electrical vehicle, control of the travelling mode based on the travelling plan created based on the scheduled traveling route before the change is maintained in accordance with a result of comparison between first attribute information and second attribute information, the first attribute information indicating an attribute of at least one section of the scheduled traveling route before the change, the second attribute information indicating an attribute of at least one section of the scheduled traveling route after the change, the at least one section of the scheduled traveling route before the change being located within a predetermined distance from a section in which the electrical vehicle is located and being located in a vehicle travelling direction, the at least one section of the scheduled traveling route after the change being located within the predetermined distance from the section in which the electrical vehicle is located and being located in the vehicle travelling direction,
• wherein even if the scheduled traveling route is changed, the controlling of the travelling mode is maintained based on the travelling plan created based on the travelling plan created based on the scheduled traveling route before the change as long as a change in an attribute of a section next to the section in which the electrical vehicle is located is less than a predetermined value, and
• wherein even if the scheduled traveling route is changed, the controlling of the travelling mode is maintained based on the travelling plan created based on the scheduled traveling route before the change as long as there is no large change in an attribute of a section next to the section in which the electrical vehicle is located.

An electrical vehicle, which includes an internal combustion engine, a storage battery, and an electric motor driven by supply of electric power from the storage battery, and travels in a plurality of traveling modes in which usage amounts of electric power of the storage battery are different, the electrical vehicle comprising

• a control unit configured to create a travelling plan in which any one of the plurality of travelling modes is assigned to each traveling section of a scheduled traveling route from a current position of the electrical vehicle to a destination, and controls the travelling mode of the electrical vehicle based on the created travelling plan,
• wherein, when the scheduled traveling route is changed during travelling of the electrical vehicle, the control unit maintains control of the travelling mode based on the travelling plan created based on the scheduled traveling route before the change, in accordance with a result of comparison between first attribute information and second attribute information, the first attribute information indicating an attribute of at least one section of the scheduled traveling route before the change, the second attribute information indicating an attribute of at least one section of the scheduled traveling route after the change, the at least one section of the scheduled traveling route before the change being located within a predetermined distance from a section in which the electrical vehicle is located and being located in a vehicle travelling direction, the at least one section of the scheduled traveling route after the change being located within the predetermined distance from the section in which the electrical vehicle is located and being located in the vehicle travelling direction,
• wherein even if the scheduled traveling route is changed, the control unit is configured to maintain the control of the travelling mode based on the travelling plan created based on the scheduled traveling route before the change as long as a change in an attribute of a section next to the section in which the electrical vehicle is located is less than a predetermined value,
• wherein even if the scheduled traveling route is changed, the control unit is configured to maintain the control of the travelling mode based on the travelling plan created based on the scheduled traveling route before the change as long as there is no large change in an attribute of a section next to the section in which the electrical vehicle is located, and
• wherein the control unit is implemented via at least one processor.
