Patent number: 10976754Abstract: A method of a method of controlling a volume of material dispensed by a constant pressure adhesive and sealant dispensing system controlled by a controller during shots includes automatically adjusting a proportional valve control setting for an orifice size of a controlled pressure regulator. An orifice size control pressure corresponding to the proportional valve control setting is applied to an orifice size control inlet of the controlled pressure regulator. A volume of the material dispensed during each shot is monitored and when the volume of material dispensed during each shot of a predetermined number of successive shots is outside a target range, the proportional valve control setting is automatically adjusted by the controller.Type: GrantFiled: September 10, 2018Date of Patent: April 13, 2021Assignee: FCA US LLCInventors: Michael D Mitchell, Phillip M Markison, John Macdonald, Michael M Zupancic

Patent number: 10400891Abstract: A system, method, and apparatus for controlling acceleration of a machine when the machine exits a grade. The system, method, and apparatus may determine a virtual gear having a maximum speed limit equivalent that matches the speed of the machine as the machine exits the grade. The system, method, and apparatus may also deactivate an automatic retarding control (ARC) strategy, which may be activated when the machine is on the grade to reduce and limit the speed of the machine to no more than a set speed, if the ARC strategy is active as the machine exits the grade. The system, method, and apparatus may also control automatic downshift of a transmission system to the virtual gear if the ARC mode was activing during the exit from the graded surface and is now deactive.Type: GrantFiled: December 15, 2017Date of Patent: September 3, 2019Assignee: Caterpillar Inc.Inventors: Austin J.

Patent number: 10246087Abstract: A system and method for mitigating collisions for an articulated work vehicle is disclosed. The system includes a controller configured to determine a safe-zone around the articulated work vehicle based on signals corresponding to sensed objects around the articulated work vehicle. The controller is further configured to determine a position and velocity of one or more peripheral points on the articulated work vehicle based on signals from a set of sensor systems operatively coupled to the articulated work vehicle. The controller is further configured to receive a driver control input. The controller is further configured to apply a limit to the driver control input when a peripheral point on the articulated work vehicle is expected to be within a predetermined distance to a nearest edge of the safe-zone.Type: GrantFiled: December 15, 2016Date of Patent: April 2, 2019Assignee: Caterpillar Inc.Inventors: Michael D.
