Controlled motion in a hydraulically actuated system

A machine comprising:

• a frame;
• a linkage pivotally connected to the frame, the linkage including a rack stop and one or more of a coupler and a work tool;
• a lift hydraulic actuator connected to the linkage and disposed to actuate the linkage relative to the frame;
• a tilt hydraulic actuator connected to the linkage and disposed to actuate the one or more of the coupler and the work tool relative to the rack stop;
• a sensor;
• and
• an electronic control module in communication with the sensor, the electronic control module configured to determine, based upon input from the sensor, that one of the coupler and the work tool is disposed in proximity to the rack stop, wherein the electronic control module is configured to cancel an actuation command to one of the lift hydraulic actuator and the tilt hydraulic actuator in response to determining that one of the coupler and the work tool is disposed in proximity to the rack stop and unintentional movement of one of the lift hydraulic actuator and the tilt hydraulic actuator is occurring.

A machine comprising:

• a frame;
• a linkage pivotally connected to the frame;
• a lift hydraulic actuator connected to the linkage, the lift hydraulic actuator including a valve;
• a tilt hydraulic actuator connected to the linkage;
• a sensor;
• and
• an electronic control module in communication with the sensor, the electronic control module configured to close the valve in response to the electronic control module determining, based upon the sensor, that unintentional motion of the lift hydraulic actuator has occurred due to actuation of the tilt hydraulic actuator.
