Vehicle stability warning system
A work machine that has a chassis, a payload section, a controller, a payload sensor in communication with the controller, and an orientation sensor that identifies the orientation of the work machine to the controller. The controller determines a center of gravity for the work machine considering a payload weight identified by the payload sensor and sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.
1. A work machine, comprising:
a chassis;
a payload section;
a controller;
a payload sensor in communication with the controller; and
a payload position assembly that identifies to the controller a location of the payload section relative to the chassis;
wherein, the controller determines a center of gravity for the work machine considering a payload weight identified by the payload sensor and the location of the payload section.
2. The work machine of claim 1 , further comprising an orientation sensor on the work machine that identifies the orientation of the work machine to the controller, wherein the controller sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.
3. The work machine of claim 2 , further comprising a sensor that communicates with the controller to identify the surrounding topography, wherein the controller considers the surrounding topography and the center of gravity to identify surrounding areas that will cause an unstable condition.
4. The work machine of claim 2 , further wherein the alert is one or more of auditory, visual, and haptic feedback.
5. The work machine of claim 3 , further wherein the sensor is a camera.
6. The work machine of claim 3 , further wherein the sensor is one or more of lidar and radar.
7. The work machine of claim 3 , further wherein the sensor is a combination of a camera and one or more of lidar and radar.
8. The work machine of claim 3 , further wherein the sensor is a GPS sensor.
9. The work machine of claim 8 , further wherein the controller accesses a topographical map and compares location identified by the GPS sensor to the topographical map to identify the surrounding areas that will cause an unstable condition.
10. The work machine of claim 9 , wherein the topographical map is selectively updated by an aerial topographical system.
11. A method for identifying an unstable condition of a work machine, comprising:
providing a chassis, a controller, a payload weight sensor, and a payload position assembly;
communicating to the controller with the payload weight sensor a weight of payload present in a payload section;
communicating to the controller with the payload position assembly a location of the payload section relative to the chassis; and
determining a center of gravity for the work machine with the controller using the weight of payload and the location of the payload section.
12. The method of claim 11 , further comprising:
providing an orientation sensor on the work machine;
communicating orientation values from the orientation sensor to the controller;
determining the orientation of the work machine with the controller based on the orientation values;
wherein, the controller sends an alert when the location of the center of gravity and the orientation of the work machine create an unstable condition.
13. The method of claim 11 , further comprising:
providing a topography sensor that communicates with the controller to identify a surrounding topography; and
considering the surrounding topography, with the controller utilizing the topography sensor, and the center of gravity to identify surrounding areas that will cause an unstable condition.
14. The method of claim 13 , further wherein the topographical sensor is a GPS sensor monitored by the controller to identify a vehicle location and the controller accesses a topographical map, wherein the controller compares the vehicle location to the topographical map to identify the surrounding areas that will cause the unstable condition.
15. The work machine of claim 14 , wherein the controller communicates with an aerial topographical system to selectively update the topographical map.
16. A method for warning of instability in a work machine, comprising:
providing a chassis having a payload section, a payload sensor in communication with a controller, an orientation sensor in communication with the controller, and a user interface;
identifying a weight of material in the payload section with the controller through the payload sensor;
determining a center of gravity of the work machine with the controller considering the weight of material in the payload section;
monitoring the orientation sensor with the controller to identify an orientation of the work machine;
identifying an unstable condition with the controller when the center of gravity and orientation of the work machine indicate the center of gravity is outside of a stability zone; and
providing a warning with the user interface to identify the unstable condition.
17. The method of claim 16 , further comprising identifying a surrounding topography with the controller and predicting unstable conditions caused by the surrounding topography.
18. The method of claim 17 , further comprising providing an indication with the user interface identifying the predicted unstable condition.
