System and method for estimating a remaining energy range of a vehicle and reducing driver range anxiety

A system for estimating a remaining range of a vehicle battery charge, the system comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to:
• identify at least one route characteristic of a portion of a selected route;
• determine a vehicle energy consumption profile for a vehicle based on at least historical data indicating energy consumption of the vehicle for at least a portion of a route previously traversed by the vehicle having at least one route characteristic corresponding to the at least one route characteristic of the portion of the selected route;
• determine a current state of charge of a vehicle battery of the vehicle;
• determine, for the selected route, a route energy consumption profile based on the at least one route characteristic of the portion of the selected route and the vehicle energy consumption profile;
• calculate an estimated remaining charge for the vehicle battery at an end of the selected route based on the state of charge of the vehicle battery and the route energy consumption profile;
• determine whether the estimated remaining charge for the vehicle battery is within a vehicle battery charge range;
• in response to a determination that the estimated remaining charge is within the vehicle battery charge range, generate a first indication;
• in response to a determination that the estimated remaining charge is less than a lower limit of the vehicle battery charge range:
• determine a target vehicle speed profile based on the at least one route characteristic, the vehicle energy consumption profile, and the state of charge of the vehicle battery;
• and
• generate a second indication;
• and
• provide one of the first indication and the second indication.

A non-transitory computer-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• identifying at least one route characteristic of a portion of a selected route;
• determining a vehicle energy consumption profile for a vehicle based on at least historical data indicating energy consumption of the vehicle for at least a portion of a route previously traversed by the vehicle having at least one route characteristic corresponding to the at least one route characteristic of the portion of the selected route;
• determining a current state of charge of a vehicle battery of the vehicle;
• determining, for the selected route, a route energy consumption profile based on the at least one route characteristic of the portion of the selected route and the vehicle energy consumption profile;
• calculating an estimated remaining charge for the vehicle battery at an end of the selected route based on the state of charge of the vehicle battery and the route energy consumption profile;
• determining whether the estimated remaining charge for the vehicle battery is within a vehicle battery charge range;
• in response to a determination that the estimated remaining charge is less than a lower limit of the vehicle battery charge range:
• determining a target vehicle speed profile based on the at least one route characteristic, the vehicle energy consumption profile, and the state of charge of the vehicle battery;
• and
• generating an indication;
• and
• providing the second indication.
