Abstract

Utilizing a database of route segments, calculating optimal velocity and acceleration profiles, and suggesting these profiles to a user or the cruise control system of the vehicle, based on a route analysis and incorporating external and local data sources relating to environmental (e.g. topographic, meteorological) conditions, traffic conditions and user preferences and characteristics.

Claims

1. A method of suggesting a driving behavior that reduces fuel consumption to a user with a communication device driving a vehicle along an estimated route, the method comprising:

receiving data related to the vehicle, the position of the vehicle, the estimated route, environmental driving conditions along the estimated route and user preferences;

segmenting the estimated route by constant fuel consumption or at constant slope;

calculating optimal velocities and accelerations for at least one relevant segment of the estimated route;

receiving vehicle position and finding a current segment during driving; and

calculating current fuel consumption and suggesting at least one of;

optimal velocity;

optimal acceleration;

optimal gear and optimal gear shifting time, during driving using the calculated optimal velocities and accelerations for the at least one relevant segment following the current segment,

wherein at least one of the receiving data, the segmenting, the calculating velocities and accelerations, the receiving and finding vehicle position and the calculating and suggesting current optimal velocity and accelerations, is carried out by at least one processing unit.

2. The method of claim 1, wherein the environmental driving conditions along the estimated route comprise at least one of:

topographical data, meteorological data, and traffic conditions.

3. The method of claim 1, further comprising calculating segment slopes by combining measured fuel consumption data, the received data and processed image data.

4. The method of claim 3, further comprising augmenting a map with the calculated segment slopes.

5. The method of claim 3, further comprising providing a map layer of a given region, the map layer comprising the calculated segment slopes from a cumulative database of vehicles moving in the given region.

6. The method of claim 1, further arranged to be implementable in association with at least one of:

a vehicle computer, a communication device, a vehicle fleet managing system, and a navigation system.

7. The method of claim 1, wherein the segmenting is carried out to generate a continuous speed velocity profile along the route.

8. The method of claim 1, further comprising indicating the recommended driving parameters and deviations therefrom to the user.

9. The method of claim 1, further comprising learning vehicle behavior and adapting the calculated optimal velocities and accelerations with respect thereto.

10. A system comprising:

a road database comprising road data,

a vehicle database comprising vehicle data from a vehicle,

a processing unit arranged to anticipate, calculate and segment a vehicle route according to driver indications, and to derive a continuous velocity profile along the route that minimizes fuel consumption with respect to the road data and the vehicle data, and

a user interface arranged to suggest driver actions along the route according to the derived velocity profile and actual derivations of the vehicle therefrom.

11. The system of claim 10, further comprising a server having an analyzing application arranged to calculate road slopes in a given region from a cumulative database of vehicles moving in the given region.
