PROCESSING UNIT AND METHOD THEREIN FOR ENABLING RELIABLE RANGE ESTIMATIONS FOR A VEHICLE ALONG A ROUTE

A processing unit segments the route into a plurality of sections. It is, for each section, obtains a set of route section characteristic values, R, that will impact the energy consumption of the vehicle whilst driving within the section, obtains a set of vehicle energy consumption values, V, that will impact the energy consumption of the vehicle whilst driving within the section at least partly based on R, estimates a first probability distribution, P, of the energy consumption for the vehicle whilst driving within the section based on R, V, and a first set of traffic information values, T, within the section, estimates a second probability distribution, P, of the energy consumption for the vehicle whilst driving within the section based on R, V, and a second set of traffic information values, T, within the section, estimates a traffic flow indicator, I, for the section based on R, Vand a third set of traffic information values, T, within the section, and determines a route section probability distribution, P, of the energy consumption for the vehicle whilst driving within the section based on the relation between I, P, and P.
