Abstract

A level indication system for a vehicle includes a control system. The control system is configured to acquire stability data regarding a stability characteristic of the vehicle at a current location, determine whether the stability characteristic is within an operational range, provide a first indication that the vehicle is reconfigurable at the current location into an operable state in response to determining that the stability characteristic is within the operational range, and provide a second indication that the vehicle is not reconfigurable at the current location into the operable state in response to determining that the stability characteristic is within a nonoperational range.

First claim

The invention claimed is:

1. A level indication system for a vehicle, the level indication system comprising:
a control system configured to:
determine whether a stability characteristic of the vehicle at a current location is within an operational range or a nonoperational range, the stability characteristic including at least one of a slope, a grade, or a jackknife angle of the vehicle;
provide (i) a first indication that the vehicle is reconfigurable at the current location into a state whereby the vehicle is operable at the current location in response to determining that the stability characteristic is within the operational range or (ii) a second indication that the vehicle is not operable at the current location in response to determining that the stability characteristic is within the nonoperational range; and
facilitate engaging a stabilization system of the vehicle in response to the stability characteristic being within the operational range and thereby reconfiguring the vehicle into a state whereby the vehicle is operable at the current location.

2. The level indication system of claim 1 , wherein the stability characteristic includes the slope and the grade of the vehicle.

3. The level indication system of claim 1 , wherein the stability characteristic includes the slope, the grade, and the jackknife angle of the vehicle.

4. The level indication system of claim 1 , wherein the operational range includes an unrestricted range and a restricted range.

5. The level indication system of claim 4 , further comprising a topography scanner positioned to acquire scan data regarding a topography characteristic of an area around the vehicle at the current location.

6. The level indication system of claim 5 , wherein the control system is configured to determine whether the topography characteristic can be used by the stabilization system to at least one of:
improve the stability characteristic from the nonoperational range to the operational range; or
improve the stability characteristic from the restricted range to the unrestricted range.

7. The level indication system of claim 4 , wherein the control system is configured to:
facilitate unrestricted operation of at least one component of the vehicle in response to the stability characteristic being within the unrestricted range;
partially restrict operation of the at least one component of the vehicle in response to the stability characteristic being within the restricted range; and
prevent operation of the at least one component of the vehicle in response to the stability characteristic being within the nonoperational range.

8. The level indication system of claim 7 , wherein the at least one component of the vehicle includes an aerial ladder assembly.

9. A level indication system for a vehicle, the level indication system comprising:
a control system configured to:
acquire stability data regarding at least one of a slope, a grade, or a jackknife angle of the vehicle at a current location;
determine whether the at least one of the slope, the grade, or the jackknife angle is within an operational slope range, an operational grade range, or an operational jackknife angle range, respectively;
provide a first indication that the vehicle is reconfigurable at the current location into an operable state in response to determining that the at least one of the slope, the grade, or the jackknife angle is within the operational slope range, the operational grade range, or the operational jackknife angle range, respectively; and
provide a second indication that the vehicle is not reconfigurable at the current location into the operable state in response to determining that the at least one of the slope, the grade, or the jackknife angle is within a nonoperational slope range, a nonoperational grade range, or a nonoperational jackknife angle range, respectively.

10. The level indication system of claim 9 , wherein the stability data includes data regarding at least two of the slope, the grade, or the jackknife angle.

11. The level indication system of claim 9 , wherein the control system is configured to activate a stabilization system of the vehicle to reconfigure the vehicle into the operable state in response to receiving a command from an operator to activate the stabilization system.

12. The level indication system of claim 9 , wherein the control system is configured to automatically activate a stabilization system of the vehicle to reconfigure the vehicle into the operable state in response to determining that the vehicle is reconfigurable into the operable state at the current location.

13. The level indication system of claim 9 , wherein the operational slope range includes an unrestricted slope range and a restricted slope range, the operational grade range includes an unrestricted grade range and a restricted grade range, and the operational jackknife angle range includes an unrestricted jackknife range and a restricted jackknife range.

14. The level indication system of claim 13 , wherein the first indication indicates (i) that the vehicle is operable with unrestricted operation at the current location in response to the at least one of the slope, the grade, or the jackknife angle being within the unrestricted slope range, the unrestricted grade range, or the unrestricted jackknife range, respectively, or (ii) that the vehicle is operable with restricted operation at the current location in response to the at least one of the slope, the grade, or the jackknife angle being within the restricted slope range, the restricted grade range, or the restricted jackknife range, respectively.

15. The level indication system of claim 13 , wherein the control system is configured to:
receive topography data regarding a topography characteristic of an area around the vehicle at the current location; and
determine whether the topography characteristic can be used by a stabilization system to at least one of:
improve at least one of the slope or the grade from the nonoperational slope range or the nonoperational grade range, respectively, to the operational slope range or the operational grade range, respectively; or
improve the at least one of the slope or the grade from the restricted slope range or the restricted grade range, respectively, to the unrestricted slope range or the unrestricted grade range, respectively.

16. A leveling system for a vehicle, the leveling system comprising:
a control system configured to:
acquire stability data regarding a stability characteristic of the vehicle at a current location;
determine whether the stability characteristic is within an operational range;
provide a first indication that the vehicle is reconfigurable at the current location into an operable state in response to determining that the stability characteristic is within the operational range; and
provide a second indication that the vehicle is not reconfigurable at the current location into the operable state in response to determining that the stability characteristic is within a nonoperational range.

17. The leveling system of claim 16 , wherein the operational range includes an unrestricted range and a restricted range.

18. The leveling system of claim 17 , wherein the control system is configured to:
receive topography data regarding a topography characteristic of an area around the vehicle at the current location; and
determine whether the topography characteristic can be used by a stabilization system to at least one of:
improve the stability characteristic from the nonoperational range
