Navigation method for determining expected energy demand of motor vehicle for predetermined route, involves determining estimated route energy demand parameter for given route depending on distance energy demand characteristics

摘要

The method involves determining (S21) distance energy demand characteristic for each section, dependent on the expected speed assigned to the respective route section. An estimated route energy demand parameter for the given route is determined (S23) depending on the respective distance energy demand characteristics. An energy requirement characteristic is determined based on the travel length for vehicle-specific energy requirement. An independent claim is included for a navigation device.
