EveDars is an on-board navigation device that enables energyefficient vehicle driving and routing. EveDars offers energyefficient driving style suggestions, instant feedback on power usage, and minimum-energy routing capabilities. Adhering to the driving-style suggestions of EveDars and following the most energy-efficient route the solution suggests can result in energy savings of up to 25%. EveDars is a new kind of on-board navigational device that uses a physical model of the vehicle to estimate currently used power in real time. Furthermore, EveDars builds a driver model which is able to predict a velocity and acceleration profile of a given driver, vehicle, and road. Displaying the estimated current power to the driver enables him or her to drive in a more efficient way. In addition, EveDars suggests a different driving behaviour based on the estimated current power and the road and vehicle conditions at hand. Besides displaying the current power and suggesting different driving behaviour, EveDars also uses a driver model, a vehicle model and a topological map to estimate the energy required to accomplish a particular driving task. Based on this information, EveDars is capable of finding the lowest energy route between two points, thereby offering unprecedented routing functionality.
The main innovation of EveDars is its minimum energy routing capability, which is based on a learned driver model, an estimated vehicle model and a topological map. Using EveDars, a given vehicle and driver can complete a particular driving task using as little fossil fuel as possible. Experiments suggest that up to 25% of fossil fuel can be saved by selecting the most efficient route and driving according to the instructions suggested by EveDars.
EveDars can be used in any road vehicle, and will thus be of interest to both consumers and/or fleet operators. Fleet operators can use EveDars to compare and analyse the particular driving styles of their different drivers and subsequently train less efficient drivers to improve the overall efficiency of the fleet.
The main customer benefit of EveDars is a significant reduction in fossil fuel consumption based on selection of the most energyefficient route. Furthermore, the real-time vehicle power display provides the operator with immediate driving-style feedback. In addition to this feedback, EveDars also provides suggestions on how to improve one’s driving style.
