Magnetorheological fluid joystick systems reducing work vehicle mispositioning

A work vehicle magnetorheological fluid (MRF) joystick system for usage onboard a work vehicle, the work vehicle MRF joystick system comprising:

• a joystick device including a joystick rotatable relative to a base housing;
• an MRF joystick resistance mechanism controllable to selectively resist rotation of the joystick relative to the base housing about at least one axis;
• an obstacle detection system configured to detect obstacles within a proximity of the work vehicle;
• and
• a controller architecture coupled to the joystick device, to the MRF joystick resistance mechanism, and to the obstacle detection system, the controller architecture having a processor and memory storing one or more computer programs executable by the processor to perform joystick control operations, including:
• in response to operator rotation of the joystick in an operator input direction, determine whether continued joystick rotation in the operator input direction will increase a likelihood of work vehicle collision with an obstacle proximate the work vehicle and detected by the obstacle detection system;
• and
• when determining that continued joystick rotation in the operator input direction will increase the likelihood of work vehicle collision, command the MRF joystick resistance mechanism to generate an MRF resistance force deterring continued joystick rotation in the operator input direction.

A work vehicle magnetorheological fluid (MRF) joystick system for usage onboard a work vehicle having a work vehicle chassis, the work vehicle MRF joystick system comprising:

• a joystick device including a joystick rotatable relative to a base housing;
• an MRF joystick resistance mechanism controllable to selectively resist rotation of the joystick relative to the base housing about at least one axis;
• a vehicle orientation data source configured to estimate a current orientation of the work vehicle chassis relative to gravity;
• and
• a controller architecture coupled to the joystick device, to the MRF joystick resistance mechanism, and to the vehicle orientation data source, the controller architecture having a processor and memory storing one or more computer programs executable by the processor to perform joystick control operations, including:
• in response to operator rotation of the joystick in an operator input direction, determine whether continued joystick rotation in the operator input direction will increase work vehicle instability based, at least in part, on the current orientation of the work vehicle chassis;
• and
• when determining that continued joystick rotation in the operator input direction will increase susceptibility of the work vehicle to collision with an obstacle, command the MRF joystick resistance mechanism to generate an MRF resistance force deterring continued joystick rotation in the operator input direction.
