Abstract

An indicator system for outdoor power equipment, such as a riding lawn mower, may include an illuminating element around the perimeter of a display screen. The illuminating element may be configured to illuminate in a predetermined manner based on a predefined condition occurring in order to alert the operator to the display screen. The display screen may be configured to display more detail about the predefined condition while the illuminating element is illuminated.

Claims

1. A lawn care vehicle comprising:

a computer system configured to determine an occurrence of a predefined condition associated with operation of the lawn care vehicle; and

an indicator system operably coupled to the computer system, the indicator system comprising an illuminating element and a display screen,

wherein the illuminating element is located adjacent to the display screen,

wherein the illuminating element is configured to illuminate in at least one of a first color or a second color,

wherein the computer system is configured to, upon detection of the occurrence of the predefined condition, display information about the predefined condition detected on the display screen and illuminate the illuminating element,

wherein the illuminating element illuminates in the first color if the predefined condition is a warning condition, and

wherein the illuminating element illuminates in the second color if the predefined condition is a neutral condition.

2. The lawn care vehicle of claim 1, wherein the illuminating element is further configured to illuminate in a third color, and wherein the illuminating element illuminates in the third color if no predefined condition is detected.

3. The lawn care vehicle of claim 2, wherein the first color, the second color, and the third color are different colors.

4. The lawn care vehicle of claim 2, wherein the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

5. The lawn care vehicle of claim 2, wherein in response to the lawn care vehicle being ready to start, the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

6. The lawn care vehicle of claim 2, wherein upon insertion of a key into an ignition of the lawn care vehicle, the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

7. The lawn care vehicle of claim 2, wherein the lawn care vehicle further comprises an override button selectable by an operator of the lawn care vehicle, wherein the override button, upon selection by the operator, is configured to override the predefined condition, and wherein in response to the override of the predefined condition, the illuminating element is configured to illuminate in the third color.

8. The lawn care vehicle of claim 1, wherein the warning condition is a fault relating to operation of the lawn care vehicle, the fault comprising at least one of:

detecting if there is no operator in an operator station;

detecting if fuel in a fuel tank has dropped below a predetermined level indicating low fuel;

detecting a service/check engine warning;

detecting a low oil/oil pressure fault;

detecting a tire pressure fault;

detecting an engine heat warning;

detecting a transmission heat warning;

detecting that RPM of a blade or an engine has passed a threshold;

or

detecting a steep incline fault.

9. The lawn care vehicle of claim 1, wherein the neutral condition comprises detecting an incoming communication from a mobile device, the incoming communication comprising a cellular telephone call, an incoming email, a text message, a short range wireless communication call, a page, or a calendar reminder.

10. The lawn care vehicle of claim 1, wherein the computer system is configured to, upon detection of the occurrence of the predefined condition, display information about the predefined condition detected on the display screen and simultaneously illuminate the illuminating element.

11. The lawn care vehicle of claim 1, wherein the first color is red, the second color is blue, and the third color is green.

12. An indicator system for a lawn care vehicle, the indicator system comprising:

an electrical system configured to determine an occurrence of a predefined condition associated with operation of the lawn care vehicle;

an illuminating element; and

a display screen,

wherein the illuminating element is located adjacent to the display screen,

wherein the illuminating element is configured to illuminate in at least one of a first color or a second color,

wherein the electrical system is configured to, upon detection of the occurrence of the predefined condition, display information about the predefined condition detected on the display screen and illuminate the illuminating element,

wherein the illuminating element illuminates in the first color if the predefined condition is a warning condition, and

wherein the illuminating element illuminates in the second color if the predefined condition is a neutral condition.

13. The indicator system of claim 12, wherein the illuminating element is further configured to illuminate in a third color, and wherein the illuminating element illuminates in the third color if no predefined condition is detected.

14. The indicator system of claim 13, wherein the first color, the second color, and the third color are different colors.

15. The indicator system of claim 13, wherein the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

16. The indicator system of claim 13, wherein in response to the lawn care vehicle being ready to start, the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

17. The indicator system of claim 13, wherein upon insertion of a key into an ignition of the lawn care vehicle, the illuminating element is configured to illuminate in the third color at least once before the detection of the occurrence of the predefined condition.

18. The indicator system of claim 12, wherein the warning condition is a fault relating to operation of the lawn care vehicle, the fault comprising at least one of:

detecting if there is no operator in an operator station;

detecting if fuel in a fuel tank has dropped below a predetermined level indicating low fuel;

detecting a service/check engine warning;

detecting a low oil/oil pressure fault;

detecting a tire pressure fault;

detecting an engine heat warning;

detecting a transmission heat warning;

detecting that RPM of a blade or an engine has passed a threshold;

or

detecting a steep incline fault.

19. The indicator system of claim 12, wherein the neutral condition comprises detecting an incoming communication from a mobile device, the incoming communication comprising a cellular telephone call, an incoming email, a text message, a short range wireless communication call, a page, or a calendar reminder.

20. The indicator system of claim 12, wherein the first color is red, the second color is blue, and the third color is green.
