Method and system for determining a route for efficient energy consumption
Various embodiments relate to determining a route for efficient energy consumption. Data defining one or more routes and one or more consumption influencing parameters which influence a consumption of an energy source of the vehicle along the one or more routes may be received at a vehicle computer. Based on the route data and the consumption influencing parameters, at least one route which minimizes the consumption of the energy source for the vehicle may be determined. For the at least one route, one or more braking strategies may be determined for implementation by a vehicle operator in the vehicle in accordance with reducing the consumption of the vehicle energy source. The one or more braking strategies may be output in the vehicle.

determine a route which minimizes vehicle energy consumption, based on received route data and a received consumption influencing parameter that influences vehicle energy consumption;
for the determined route, determine a vehicle energy consumption reduction braking strategy that relies on different energy preservation strategies correlating to different route portions; and
output the braking strategy in the vehicle, changing output energy preservation strategies as correlated route portions are reached.
