Abstract

A riding yard maintenance vehicle may include a positioning module. The positioning module may include processing circuitry configured to receive information indicative of vehicle position of the riding yard maintenance vehicle, receive an indication of a triggering event that indicates a presence of an obstacle proximate to the riding yard maintenance vehicle, and cause recordation of an obstacle identifier in association with the vehicle position responsive to receipt of the indication.

Claims

1. A method comprising:

receiving information indicative of a first vehicle position of a riding yard maintenance vehicle;

receiving an indication of a triggering event, the triggering event indicating a presence of an obstacle proximate to the riding yard maintenance vehicle when the riding yard maintenance vehicle is in the first vehicle position, wherein the triggering event comprises a passive event, the passive event comprising an engine operation parameter exceeding a threshold;

causing, via processing circuitry, recordation of an obstacle identifier in association with the first vehicle position responsive to receipt of the indication; and

generating an operational control function responsive to a second vehicle position being within a predefined distance of the recorded obstacle identifier,

wherein generating the operational control function comprises;

stopping rotation of a cutting blade of the riding yard maintenance vehicle, stopping operation of a power-take-off (PTO) of the riding yard maintenance vehicle, or adjusting a height of the cutting blade of the riding yard maintenance vehicle.

2. The method of claim 1, wherein the engine operation parameter is a change in engine revolutions per minute (RPM);

or

a change in engine torque.

3. The method of claim 1, wherein the triggering event further comprises an active event, the active event comprising:

operator selection of a button to cause generation of the obstacle identifier associated with the first vehicle position;

or

operator placement of an obstacle marker on a graphical display in association with a route or parcel on which the riding yard maintenance vehicle is operating.

4. The method of claim 1, wherein receiving the information and receiving the indication each occur locally at the riding yard maintenance vehicle.

5. The method of claim 1, wherein receiving the information and receiving the indication each occur remotely from the riding yard maintenance vehicle.

6. The method of claim 1, wherein receiving the information and receiving the indication each occur at a mobile communication device of an operator of the riding yard maintenance vehicle.

7. The method of claim 4, wherein causing recordation of the obstacle identifier comprises storing the obstacle identifier in a database locally at the riding yard maintenance vehicle.

8. The method of claim 4, wherein causing recordation of the obstacle identifier comprises storing the obstacle identifier in a database remote from the riding yard maintenance vehicle.

9. The method of claim 1, further comprising prompting an operator to save, define desired automatic responses, or add annotations responsive to the triggering event.

10. The method of claim 1, wherein the triggering event further comprises an active event, the active event comprising receiving a user annotation or desired vehicle response from an operator.

11. The method of claim 1 further comprising:

generating an alert responsive to the second vehicle position being within the predefined distance of the recorded obstacle identifier.

12. The method of claim 1 further comprising:

prompting an operator of the riding yard maintenance vehicle to confirm whether the triggering event should be marked as the obstacle identifier.

13. A riding yard maintenance vehicle comprising:

ground contacting wheels;

an engine operably coupled to the ground contacting wheels;

a steering assembly operably coupled to the ground contacting wheels to direct movement of the riding yard maintenance vehicle based on operator steering inputs; and

a positioning module configured to enable storage of vehicle position information, the positioning module comprising processing circuitry configured to;

receive information indicative of a first vehicle position of the riding yard maintenance vehicle;

receive an indication of a triggering event, the triggering event indicating a presence of an obstacle proximate to the riding yard maintenance vehicle when the riding yard maintenance vehicle is in the first vehicle position, wherein the triggering event comprises a passive event, the passive event comprising a change in engine revolutions per minute (RPM) above a threshold amount, a change in engine torque above a threshold amount, or a change in cutting deck sound;

cause recordation of an obstacle identifier in association with the first vehicle position responsive to receipt of the indication; and

generate an operational control function responsive to a second vehicle position being within a predefined distance of the recorded obstacle identifier,

wherein generating the operational control function comprises;

stopping rotation of a cutting blade of the riding yard maintenance vehicle, stopping operation of a power-take-off (PTO) of the riding yard maintenance vehicle, or adjusting the height of a cutting blade of the riding yard maintenance vehicle.

14. The riding yard maintenance vehicle of claim 13, wherein the triggering event further comprises an active event comprising:

operator selection of a button to cause generation of the obstacle identifier associated with the first vehicle position;

or

operator placement of an obstacle marker on a graphical display in association with a route or parcel on which the riding yard maintenance vehicle is operating.

15. The riding yard maintenance vehicle of claim 13, wherein the processing circuitry is further configured to generate an alert responsive to the second vehicle position being within the predefined distance of the recorded obstacle identifier.

16. The riding yard maintenance vehicle of claim 15, wherein the processing circuitry is further configured to prompt an operator of the riding yard maintenance vehicle to confirm whether the triggering event should be marked as the obstacle identifier.

17. A method comprising:

receiving information indicative of a vehicle position of a riding yard maintenance vehicle;

comparing, via processing circuitry, the vehicle position to a recorded location associated with an obstacle identifier, the recorded location being associated with a previous vehicle position of the riding yard maintenance vehicle and the recorded location having been stored in response to a triggering event comprising a passive event, the passive event comprising an engine operation parameter exceeding a threshold; and

generating, based on the comparing, an operational control function responsive to the vehicle position being within a predefined distance of the recorded location,

wherein generating the operational control function comprises;

stopping rotation of a cutting blade of the riding yard maintenance vehicle, stopping operation of a power-take-off (PTO) of the riding yard maintenance vehicle, or adjusting a height of the cutting blade of the riding yard maintenance vehicle.

18. The method of claim 17, wherein the recorded location is stored locally at the riding yard maintenance vehicle, or at a location stored remotely from the riding yard maintenance vehicle and provided to the riding yard maintenance vehicle, and wherein receiving the information, comparing the vehicle position to the recorded location, and generating the alert each occur at the riding yard maintenance vehicle, or at a mobile communication device of an operator of the riding yard maintenance vehicle.

19. The method of claim 17, further comprising generating an alert responsive to the vehicle position being within a predefined distance of the recorded location.
