Abstract: A work vehicle comprising a frame supported by a ground engaging device. A boom assembly is coupled to the frame. An attachment coupler is coupled to the boom assembly. An electronic data processor is communicatively coupled to a boom actuator, an attachment coupler actuator, a boom sensor, an attachment coupler sensor, and an operator input device. A computer readable storage medium comprising machine readable instructions that, when executed by the processor, cause the processor to receive an operator input and for a tilt forward command, command the boom actuator to move the boom assembly to a frame contact position and then command the attachment coupler actuator to move the attachment coupler towards a lower position. For a tilt rearward command, command the attachment coupler actuator to move the attachment coupler towards an upper position and then command the boom actuator to move the boom assembly towards a raised position.

Abstract: A control system for moving an end effector of a work machine may include sensors for determining current orientations of components of a boom assembly connected to the work machine. A controller may be configured to receive, via an input interface, signals corresponding to a velocity input command for a desired movement of the end effector. The controller may determine, based upon the velocity input command and signals from the sensors, at least one target velocity for one or more actuators for the boom assembly. Commanding the actuators to move with the at least one target velocity may cause the end effector to move with an aggregate velocity corresponding to the desired movement of the end effector, as indicated by the velocity input command.
