Abstract:

A gateway interface controller for a work machine includes a CAN bus interface component configured to communicate over a CAN bus of the work machine. The gateway interface controller includes message logic configured to process a request signal, indicative of a requested work machine action, that is received from a remote control, wherein the message logic validates the request signal based on a validation criterion. The gateway interface controller includes command generator logic configured to, based on the validation, generate a CAN signal that corresponds to the request signal and communicate the CAN signal over the CAN bus.

Abstract:

A pressure compensated load sense hydraulic system and method is disclosed where a first pressure compensated valve controls flow between a pump and a first function based on a highest function load; and a second pressure compensated valve controls flow between the pump and a second function based on the highest function load. First and second operator controls activate the first and second functions, respectively. When the first function is stalled and the second function is activated, the controller closes the first valve to remove the first function load from the load sense circuit and prevent flow to or from the first function. The controller can determine the first function is stalled when a timer exceeds an initialization period. When the controller closes the first valve, it can cycle the first valve between a shutoff period where the valve is closed, and a refresh period where the valve is opened.
