1. A method of optimizing energy efficiency of a vehicle for known routes, the method comprising:

  • collecting, by a processor, and storing, in a memory, first time data of a first previously-travelled route and first location data for the first previously-travelled route;

    collecting, by the processor, and storing, in the memory, second time data of a second previously-travelled route and second location data for the second previously-travelled route;

    determining, by the processor, a link between the first previously-travelled route and the second previously-travelled route based on at least one of the first time data, the first location data, the second time data, or the second location data;

    categorizing, by the processor, the link between the first previously-travelled route and the second previously-travelled route into a respective link category of a plurality of link categories based on a time period between the vehicle having travelled the first previously-travelled route and the vehicle having travelled the second previously-travelled route;

    determining or predicting, by the processor, a predicted route that includes the first previously-travelled route and the second previously-travelled route that the vehicle will travel over; and

    controlling, by the processor, a sequence of a usage of an engine and a battery of the vehicle in advance of or during travelling of the vehicle on the predicted route based on the respective link category of the link between the first previously-travelled route and the second previously-travelled route to optimize the energy efficiency of the vehicle for travel along the predicted route.
