Work implement control based on tire pressure in a construction vehicle

A work vehicle including a work implement operatively connected to a frame supported to move over a surface by a plurality of pneumatic tires comprising:

• an actuator operatively connected to the work implement, the actuator to move the work implement with respect to the frame;
• control circuitry operatively connected to the actuator, the control circuitry including a processer and a memory, wherein the memory has a plurality of program instructions stored thereon, that in response to execution by the processor causes the control circuitry to:
• establish a grade target of a surface to be prepared by the work implement;
• identify a position of the work implement with respect to the vehicle frame based on a signal received from a work implement sensor actuator;
• identify a tire pressure of one or more of the plurality of tires based a signal received from a tire sensor;
• and
• adjust the position of the work implement with respect to the frame using a linkage arrangement, wherein the adjusted position is based on the identified tire pressure of the one or more plurality of pneumatic tires and based on the established grade target.

A work vehicle grade control system of a vehicle having a plurality of pneumatic tires, a frame supported by the plurality of tires, and a grader blade to move through a range of positions with respect to the frame to grade a surface, the control system comprising:

• a machine control system operatively connected to the frame, the machine control system to provide a grade signal;
• a tire pressure sensor operatively connected to the at least one of the plurality of tires, the tire pressure sensor to provide a tire pressure signal;
• an actuator operatively connected to the grader blade, the actuator to move the grader blade with respect to the frame;
• control circuitry operatively connected to the grade control system, the tire pressure sensor and the actuator, the control circuitry including a processer and a memory, wherein the memory has a plurality of program instructions stored thereon, that in response to execution by the processor causes the control circuitry to:
• identify a current grade of the surface based on the grade signal received from the machine control system;
• identify a position of the grader blade with respect to the surface;
• identify a tire pressure of one or more of the plurality of tires;
• and
• adjust the position of the grader blade with respect to the frame based on the identified current grade and the identified tire pressure of the one or more plurality of pneumatic tires.
