Optimizing blade engagement depth using engine load data

A computer-implemented method, comprising, executing a first control loop and a second control loop using a control computing device to control a height of a cutting blade during operation of a work vehicle within an operating site;

• wherein the first control loop comprises:
• determining a target engine load range based on features of the operating site, wherein the target engine load range is defined by a minimum target engine load value and a maximum target engine load value separated by a range of engine load values;
• receiving, from an engine load sensor device, a value of an engine load of an engine of the work vehicle operating within the operating site;
• comparing the value of the engine load to the target engine load range;
• responsive to determining that the value of the engine load is less than the minimum target engine load value, lowering a cutting blade of the work vehicle to increase an engagement of the cutting blade with a surface or subsurface of the operating site;
• and
• responsive to determining that the engine load is greater than the maximum target engine load value, raising the cutting blade of the work vehicle to decrease the engagement of the cutting blade with the surface or subsurface of the operating site;
• wherein the second control loop comprises:
• receiving, from a blade height sensor device, a blade height value indicating a current blade height of the cutting blade of the work vehicle;
• accessing a design indicating a target surface or subsurface height for the operating site, the design defining a target blade height;
• comparing the current blade height to the target blade height;
• responsive to determining that the current blade height is higher than the target blade height, calculating a lower blade height to achieve target parameters, and adjusting the cutting blade lower by a predetermined amount;
• responsive to determining that the current blade height is lower than the target blade height, calculating a higher blade height to achieve target parameters;
• and
• adjusting the cutting blade to the calculated higher blade height;
• wherein the first control loop is executed back and forth with the second control loop so that each pass of the first control loop is followed by a pass of the second control loop.

A system, comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium comprising computer-executable instructions that, when executed by the one or more processors, cause the system to:
• execute a first control loop and a second control loop;
• wherein executing the first control loop causes the system to:
• receive, from an engine load sensor device, a value of an engine load of an engine of an equipment operating in an operating environment;
• compare the value of the engine load to a target engine load range defined by a minimum target engine load value and a maximum target engine load value;
• responsive to determining that the value of the engine load is less than the minimum target engine load value, lower a cutting blade of the equipment to increase an engagement of the cutting blade with a surface or subsurface of the operating environment;
• and
• responsive to determining that the engine load is greater than the maximum target engine load value, raise the cutting blade of the equipment to decrease the engagement of the cutting blade with the surface or subsurface of the operating environment;
• wherein executing the second control loop causes the system to:
• receive, from a blade height sensor device, a blade height value indicating a current blade height of the cutting blade of the equipment;
• access a design indicating a target surface or subsurface height for the operating environment, the design defining a target blade height;
• compare the current blade height to the target blade height;
• responsive to determining that the current blade height is higher than the target blade height, calculate a lower blade height to achieve target parameters, and adjust the cutting blade lower by a predetermined incremental amount;
• responsive to determining that the current blade height is lower than the target blade height, calculate a higher blade height to achieve target parameters;
• and
• adjust the cutting blade to the calculated higher blade height;
• wherein the first control loop is executed alternatingly with the second control loop.
