Method for determining energy efficient rolling speed of e.g. hybrid vehicle, involves seizing rolling speed according to actual rolling state and specific information of vehicle, where actual state is actual energy consumption of vehicle

摘要

The method involves seizing energy efficient rolling speed (102) according to an actual rolling state and specific information of a vehicle, where the actual rolling state is actual speed and actual energy consumption of the vehicle. The actual energy need from the actual power of the engine and inclination of an actual roadway are determined (104). The specific information of the vehicle is provided with an energy consumption curve and a transmission characteristic curve. Independent claims are also included for the following: (1) a Device for determining energy efficient rolling speed of a vehicle, comprising a determination unit (2) a computer program product comprising a set of instructions to perform a method for determining energy efficient rolling speed of a vehicle.
