Patent ID: 8620573

Claim:
A method for determining a route from a starting point to a destination point in a navigation system for a motor vehicle, the method comprising: determining the route as a function of a factor which describes at least one of an energy consumption and pollutant emissions during motor vehicle standstills; statistically determining the factor from a duration of a current standstill and associated standstill durations; storing associations of the duration of the current standstill with locations to which the motor vehicle has not yet traveled, which associations are created only for locations that are determined to be similar to a current location of the motor vehicle; and responsive to a determination that the duration of the current standstill exceeds an average waiting time at the current location, outputting a recommendation for shutting down at least one of an energy source of the motor vehicle and a pollutant source of the motor vehicle; wherein the factor is determined in relation to an environmental condition including ambient temperature and season.
