Energy efficiency of a car driving with regenerative braking
The fuel consumption or electricity consumption of vehicles in road traffic depends on many factors related to the vehicle specification but also to the traffic conditions and road gradients. In the case of vehicles equipped with regenerative braking, the guidelines for the economical route may differ significantly from those for vehicles with conventional drives. Currently offered satellite navigation systems for cars are primarily focused on selecting the route with the shortest travel time. These systems also feature relatively simple models that allow the selection of the route with regard to minimizing fuel or electricity consumption, usually called the most ecological. Their effective use requires users to define basic vehicle data, such as drive type, maximum speed, etc. The paper presents an analysis of the impact of selected parameters characterizing vehicle properties and traffic conditions on energy consumption. The focus is mainly on parameters that can be technically used in car navigation systems to plan energy-saving routes. The analysis uses routes recorded in real traffic.
