Navigation device, navigation method, and navigation program

A navigation method for a host vehicle, the method comprising:

• acquiring a reference position related to a traveling of the host vehicle;
• acquiring a vehicle condition of the host vehicle at the reference position, the vehicle condition being at least one of a state of charge of a battery of the host vehicle and a number of occupants of the host vehicle;
• accessing a travel information storage unit that stores past travel sequences, stored data for each travel sequence including:
• at least one position along the travel sequence, operation information that specifies a vehicle operation at each stored position, and vehicle condition information that specifies a vehicle condition at each stored position, the vehicle condition being at least one of a state of charge of a vehicle battery and a number of occupants;
• identifying a stored sequence of travel having a stored position that corresponds to the acquired reference position of the host vehicle and having stored vehicle condition information that corresponds to the acquired vehicle condition of the host vehicle;
• acquiring the stored operation information of the identified stored sequence of travel;
• generating display information based on the acquired operation information;
• and
• causing the generated display information to be displayed on a display.

A non-transitory computer-readable medium storing a computer-executable program, the program comprising:

• instructions for acquiring a reference position related to a traveling of a host vehicle;
• instructions for acquiring a vehicle condition of the host vehicle at the reference position, the vehicle condition being at least one of a state of charge of a battery of the host vehicle and a number of occupants of the host vehicle;
• instructions for accessing a travel information storage unit that stores past travel sequences, stored data for each travel sequence including:
• at least one position along the travel sequence, operation information that specifies a vehicle operation at each stored position, and vehicle condition information that specifies a vehicle condition at each stored position, the vehicle condition being at least one of a state of charge of a vehicle battery and a number of occupants;
• instructions for identifying a stored sequence of travel having a stored position that corresponds to the acquired reference position of the host vehicle and having stored vehicle condition information that corresponds to the acquired vehicle condition of the host vehicle;
• instructions for acquiring the stored operation information of the identified stored sequence of travel;
• instructions for generating display information based on the acquired operation information;
• and
• instructions for causing the generated display information to be displayed on a display.
