Abstract

Methods, systems, and apparatus for selectively learning and displaying information for a coasting guidance system. The system includes an electronic control unit (ECU) configured to determine a stop event location where a coasting guidance instruction is displayed. The system includes a memory configured to store one or more stop event locations. The system includes a display configured to display the stored one or more stop event locations on a map. The display is configured to receive an indication of a coasting guidance area on the map. The display is configured to identify a portion of the stored one or more stop event locations within the coasting guidance area. The display is configured to selectively display the portion of the one or more stop event locations on the map such that a stop event location outside of the coasting guidance area is absent from the map.

and

selectively display the portion of the one or more previously determined coasting locations on the map such that a previously determined coasting location outside of the coasting guidance area is absent from the map.

2. The system of claim 1, wherein the coasting guidance area is a closed area on the map identified by the user.

3. The system of claim 1, wherein the coasting guidance area is an area of the map other than a closed area on the map identified by the user.

4. The system of claim 1, further comprising:

a navigation unit configured to detect a current location of the vehicle, and

wherein the ECU is further configured to;

determine a location of a new coasting location,

determine, based on the current location of the vehicle, whether the location of the new coasting location is within the coasting guidance area, and

store the location of the new coasting location in memory when the location of the new coasting location is within the coasting guidance area.

5. The system of claim 1, further comprising a navigation unit configured to detect a current location of the vehicle,

wherein the ECU is further configured to:

detect, based on the current location of the vehicle, whether the vehicle is approaching a coasting location of the one or more coasting locations, and

determine whether the coasting location being approached is within the coasting guidance area, and

wherein the display is configured to provide the coasting guidance as the vehicle approaches the coasting location when the coasting location being approached is within the coasting guidance area.

6. The system of claim 1, wherein the display is further configured to:

receive, from the user, an indication to display removed coasting locations located outside of the coasting guidance area, and

display the removed coasting locations on the map.

7. The system of claim 1, further comprising a navigation unit configured to detect a current location of the vehicle,

wherein the coasting location is determined based on sensor data detected by a sensor, and

wherein the detection of sensor data is disabled when the current location of the vehicle is outside of the coasting guidance area.

8. The system of claim 1, wherein the ECU is further configured to identify a portion of the stored one or more coasting locations based on the indicated coasting guidance area, the portion of the one or more coasting locations being within the coasting guidance area.

9. A vehicle comprising:

an electronic control unit (ECU) configured to determine a coasting location where coasting guidance is provided as the vehicle approaches the coasting location, the coasting guidance indicating when a driver of the vehicle should disengage from a brake pedal of the vehicle and an accelerator pedal of the vehicle;

a memory connected to the ECU, the memory configured to store one or more previously determined coasting locations; and

a display connected to the ECU, the display configured to;

display the stored one or more previously determined coasting locations on the map,

receive, from a user, a selection of a coasting guidance exclusion area on the map, the coasting guidance exclusion area being a portion of the map where previously determined coasting locations should not be displayed on the map,

and

selectively display the portion of the one or more step previously determined coasting locations on the map such that a previously determined coasting location inside the coasting guidance exclusion area is absent from the map.

10. The vehicle of claim 9, wherein the coasting guidance exclusion area is a closed area on the map identified by the user.

11. The vehicle of claim 9, wherein the coasting guidance exclusion area is an area of the map other than a closed area on the map identified by the user.

12. The vehicle of claim 9, further comprising:

a navigation unit configured to detect a current location of the vehicle, and

wherein the ECU is further configured to;

determine a location of a new coasting location,

determine, based on the current location of the vehicle, whether the location of the new coasting location is within the coasting guidance exclusion area, and

disregard the location of the new coasting location when the new coasting location is within the coasting guidance exclusion area, such that the location of the new coasting location is not stored in memory.

13. The vehicle of claim 9, further comprising a navigation unit configured to detect a current location of the vehicle,

wherein the ECU is further configured to:

detect, based on the current location of the vehicle, whether the vehicle is approaching a coasting location of the one or more coasting locations, and

determine whether the coasting location being approached is within the coasting guidance exclusion area, and

wherein the display does not display the coasting guidance instruction as the vehicle approaches the coasting location when the coasting location being approached is within the coasting guidance exclusion area.

14. The vehicle of claim 9, further comprising a navigation unit configured to detect a current location of the vehicle,

wherein the ECU is further configured to:

detect, based on the current location of the vehicle, whether the vehicle is approaching a coasting location of the one or more coasting locations, and

determine whether the coasting location being approached is within the coasting guidance exclusion area, and

wherein the display provides the coasting guidance as the vehicle approaches the coasting location regardless of whether the coasting location being approached is within the coasting guidance exclusion area.

15. The vehicle of claim 9, further comprising a navigation unit configured to detect a current location of the vehicle,

wherein the coasting location is determined based on sensor data detected by a sensor, and

wherein the detection of sensor data is disabled when the current location of the vehicle is inside of the coasting guidance exclusion area.
