Abstract
A mobile agricultural machine includes a set of ground engaging elements, a controllable subsystem configured to perform a work operation on a field, and a control system. The control system is configured to identify a work performance metric representing a performance characteristic of the work operation having an inverse relationship to traversal speed of the mobile agricultural machine over the field, receive an indication of operator presence relative to the mobile agricultural machine, generate a weighting parameter that weights the work performance metric relative to a ride quality metric based on the indication of operator presence, determine a target machine speed based on the weighting parameter, and output a control instruction based on the target machine speed.

A mobile agricultural machine comprising:
- a set of ground engaging elements;
- a controllable subsystem configured to perform a work operation on a field;
- and
- a control system configured to:
- identify a work performance metric representing a performance characteristic of the work operation having an inverse relationship to traversal speed of the mobile agricultural machine over the field;
- receive an indication of operator presence relative to the mobile agricultural machine;
- generate a weighting parameter that weights the work performance metric relative to a ride quality metric based on the indication of operator presence;
- determine a target machine speed based on the weighting parameter;
- and
- output a control instruction based on the target machine speed.
A method of controlling a mobile agricultural machine, the method comprising:
- identifying a work performance metric representing a performance characteristic of a work operation having an inverse relationship to traversal speed of the mobile agricultural machine over a field;
- receiving an indication of operator presence with respect to the mobile agricultural machine;
- generating a weighting parameter that weights the work performance metric relative to a ride quality metric based on the indication of operator presence;
- determining a target machine speed based on the weighting parameter;
- and
- outputting a control instruction based on the target machine speed.
An agricultural machine control system comprising:
- at least one processor;
- and
- memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the agricultural machine control system to:
- identify a work performance metric representing a performance characteristic of a work operation having an inverse relationship to traversal speed of a mobile agricultural machine over a field;
- receive an indication of operator presence with respect to the mobile agricultural machine;
- generate a weighting parameter that weights the work performance metric relative to a ride quality metric based on the indication of operator presence;
- determine a target machine speed based on the weighting parameter;
- and
- output a control instruction based on the target machine speed.
