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

A method performed by a processing unit for enabling reliable range estimations for a vehicle along a route from a source location to a target destination. The processing unit is configured to segment the route into a plurality of sections. It is also configured to, for each section, obtain a set of route section characteristic values, Rscv, that will impact the energy consumption of the vehicle whilst driving within the section, obtain 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 Rscv, estimate 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, estimate a second probability distribution, P, of the energy consumption for the vehicle whilst driving within the section based on Rscv, V, and a second set of traffic information values, T, within the section, estimate a traffic flow indicator, I, for the section based on R, V and a third set of traffic information values, T, within the section, and determine 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. It is further configured to determine a route probability distribution, P, of the energy consumption for the vehicle whilst driving along the route based on the estimated P for all sections.
