Abstract

A start fault indicator system for outdoor power equipment may include an illuminating element and circuitry to perform start condition checks to determine if a start fault has occurred. The illuminating element may be configured to illuminate a first predetermined color in response to detection of a start fault occurring, and illuminate a second predetermined color in response to determining that no start fault is outstanding, where the first and second predetermined colors are different colors.

First claim

That which is claimed:

1. A riding lawn care vehicle, comprising:
an engine;
a start fault indicator system configured to run a check for faults that should be corrected prior to starting the engine, the start fault indicator system comprising:
an illuminating element;
circuitry to perform start fault checks to determine if a start fault has occurred;
wherein the illuminating element is configured to present a first predetermined color in response to detection of a start fault occurring, and
wherein the illuminating element is configured to present a second predetermined color in response to determining that no start faults are outstanding, the first and second predetermined colors being different colors; and

an operator presence sensor for sensing a presence of an operator on the riding lawn care vehicle, wherein the start fault indicator system is configured to initiate the start fault checks in response to the operator presence sensor sensing the presence of the operator on the riding lawn care vehicle when the engine is not started.

2. The riding lawn care vehicle of claim 1 , further comprising:
an ignition configured to receive a key, wherein the start fault indicator system is configured to initiate the start fault checks in response to the key being inserted into the ignition.

3. The riding lawn care vehicle of claim 1 , further comprising:
an ignition configured to receive a key, wherein the start fault indicator system is configured to initiate the start fault checks in response to the key being inserted into the ignition and turned.

4. The riding lawn care vehicle of claim 1 , further comprising:
an ignition configured to start the engine of the riding lawn care vehicle in response to operator input, wherein the start fault indicator system is configured to prevent the ignition from starting the engine until all detected start faults are cleared or overridden.

5. The riding lawn care vehicle of claim 1 , wherein the determining if the start fault has occurred comprises at least one of:
detecting brakes of the riding lawn care vehicle not being engaged;
detecting that there is no operator in a seat of the riding lawn care vehicle; or
detecting if blades of a cutting deck of the riding lawn care vehicle are on.

6. The riding lawn care vehicle of claim 1 , further comprising a display screen configured to:
display textual detail about a detected start fault based at least partially on the illuminating element being illuminated; and
display data relating to a default predetermined mode in response to detection of no outstanding start faults.

7. The riding lawn care vehicle of claim 1 , wherein the start fault indicator system further comprises a mode select button configured to select what data the display screen outputs.

8. The riding lawn care vehicle of claim 1 , wherein the start fault indicator system further comprises an override button that, when activated, is configured to override an outstanding start fault in response to the outstanding start fault occurring.

9. The riding lawn care vehicle of claim 1 , wherein the illuminating element at least partially surrounds a perimeter of a display screen, and the display screen is configured to display text or graphics relating to a start fault.

10. A method of alerting an operator of a riding lawn care vehicle, comprising:
performing start fault checks to determine if a start fault has occurred, the start fault being of a nature that should be corrected prior to starting an engine of the riding lawn care vehicle, wherein the start fault checks are performed in response to an operator presence sensor sensing a presence of the operator on the riding lawn care vehicle when the engine is not started,
sending a signal, using a computing device, to an illuminating element to present a first predetermined color in response to detection of a start fault occurring, the detection being caused by detecting one or more predetermined triggers, and
sending a signal to the illuminating element to present a second predetermined color in response to determining that no start faults are outstanding, the first and second predetermined colors being different colors.

11. The method of claim 10 , further comprising in response to a predetermined triggering condition having occurred, displaying details about the predetermined triggering condition while the illuminating element is illuminated.

12. The method of claim 10 , further comprising:
in response to a predetermined triggering condition having been detected indicating an alert is outstanding:
determining that the alert has been corrected or addressed; and
changing illumination of the illuminating element from the second predetermined color to the first predetermined color.

13. The method of claim 10 , further comprising:
in response to a predetermined triggering condition having been detected indicating an alert is outstanding:
receiving activation from an override button indicating that a user desires to override the predetermined triggering condition;
determining whether override of the predetermined triggering condition is allowed; and
in response to determining that override is allowed for the predetermined triggering condition and in response to receiving activation from the override button, overriding the alert so that the alert is no longer outstanding.

14. The method of claim 10 , wherein the determining if any predetermined triggering conditions have occurred comprises determining if the operator is seated in a seat of the riding lawn care vehicle,
wherein in response to determining the operator is seated in the seat, illuminating the illuminating element to the first predetermined color; and
wherein in response to determining the operator is not seated in the seat, illuminating the illuminating element to the second predetermined color and displaying text on a display screen indicating a no operator fault.

15. The method of claim 10 , wherein the determining if any predetermined triggering conditions have occurred comprises detecting if brakes of the riding lawn care vehicle are not engaged, and
wherein in response to detecting that brakes of the riding lawn care vehicle are engaged, illuminating the illuminating element to the first predetermined color; and
wherein in response to detecting that brakes of the riding lawn care vehicle are not engaged, illuminating the illuminating element to the second predetermined color and displaying text on a display screen indicating a braking engaged fault.

16. The method of claim 10 , wherein the determining if any predetermined triggering conditions have occurred comprises detecting if blades of a cutting deck of the riding lawn care vehicle are on, and
wherein in response to detecting that blades of the cutting deck of the riding lawn care vehicle are not on, illuminating the illuminating element to the first predetermined color; and
wherein in response to detecting that if blades of the cutting deck of the riding lawn care vehicle are on, illuminating the illuminating element to the second predetermined color and displaying text on a display screen indicating a blades on fault.

17. A start fault indicator system for outdoor power equipment comprising:
an illuminating element;
circuitry to perform start condition checks to determine if a start fault has occurred;
wherein the illuminating element is configured to:
illuminate a first predetermined color in response to detection of a start fault occurring, and
illuminate a second predetermined color in response to determining that no st
