Vehicle leveling assembly with mobile device
An assembly for correcting an attitude of at least a selected portion of a structure, where the assembly includes a controller affixed to a structure operatively coupled with one or more jacks operable to change the attitude of the structure; and a remote device configured to communicate wirelessly with the controller to change the attitude of a selected portion of the structure. Also disclosed is a method for adjusting an attitude of a movable structure.
1. A system for correcting an attitude of a structure having one or more jacks affixed about the structure and operable to change the attitude of the structure, the system comprising:
a multi-axis digital sensor that is unattached to the structure and configured to measure an orientation of a selected portion of the structure at which the multi-axis digital sensor is placed;
a controller in wireless communication with said multi-axis digital sensor and configured to cause adjustment of the one or more jacks in order to change the attitude of the structure; and
a processor configured to receive measurements from the multi-axis digital sensor and determine an adjustment of the one or more jacks to actuate the one or more jacks based on the measurements and thereby move the selected portion of the structure into a desired attitude.
2. The system according to claim 1 , wherein the processor is a component of the multi-axis digital sensor.
3. The system according to claim 1 , wherein the processor is a component of the controller.
4. The system according to claim 3 , wherein the processor is configured to execute a filter algorithm that filters noise from a digital output signal of the multi-axis digital sensor to allow the controller to recognize ground contact with the one or more jacks.
5. The system according to claim 3 , wherein the filter algorithm is an adaptive filter algorithm that adjusts a filter value based on an operational mode of the controller, and wherein the operational mode is a ground contact operation or a leveling sequence.
6. The system according to claim 1 , wherein the processor, the multi-axis digital sensor, and the controller are all components of a remote device that is remote of the structure.
7. The system of claim 6 , wherein the remote device is a smart phone or a tablet computer.
8. The system according to claim 1 , wherein the multi-axis digital sensor is configured to measure the attitude of the structure with respect to three or more axes.
9. The system according to claim 8 , wherein the multi-axis digital sensor is configured to measure the attitude of the structure with respect to at least a longitudinal pitch axis, a lateral roll axis, and a normal axis.
10. The system according to claim 1 , wherein the processor is configured to determine a relative alignment of the axes of the multi-axis digital sensor to the axes of the structure based on the multiple readings acquired by the multi-axis digital sensor.
11. The system according to claim 1 , further comprising a memory configured to store instructions to be executed by the processor.
12. A method for adjusting an attitude of a structure, the method comprising:
monitoring a level of the structure, with a multi-axis digital sensor unattached to the structure, the multi-axis digital sensor configured to wirelessly communicate with a controller configured to modify an extension distance of one or more jacks affixed to the structure; and
with the controller, adjusting the extension distance of the one or more jacks based on a measured shift in the level of the structure from a zero leveling point.
13. The method according to claim 12 , wherein the level of the structure is monitored by the multi-axis digital sensor with respect to at least three axes of the structure.
14. The method according to claim 12 , further comprising:
acquiring a first reading from the multi-axis digital sensor;
adjusting the extension distance of the one or more jacks to determine an orientation of the multi-axis digital sensor;
acquiring a second reading from the multi-axis digital sensor; and
determining the relative alignment of the axes of the multi-axis digital sensor to the axes of the structure based on the first reading and the second reading.
15. The method according to claim 12 , further comprising: determining the zero leveling point of the structure.
16. The method according to claim 12 , further comprising, via a user interface of a remote device in which the processor is provided and which is remote from the structure:
receiving a request to initiate an attitude adjustment operation,
in response to the request, providing an instruction to place the remote device on a selected portion of the structure to be adjusted, and
soliciting a confirmation that the remote device has been placed on the selected portion of the structure to be adjusted prior to initiating the attitude adjustment operation.
