Abstract: A method for preventing prime mover stall for a work machine including a hydraulic system having a plurality of control valves served by a hydraulic pump. The method can include determining an actual required flow rate value for the plurality control valves and a total maximum flow rate to the plurality of control valves that will enable the prime mover to operate without stalling. The method can also include operating the plurality of control valves such that the combined total flow of the plurality control valves is at or below the total maximum flow rate such that the pump operates at a condition below which prime mover stall will occur. The method can also include setting a flow sharing allocated specific criteria in which the flow reduction takes place during a flow saturation condition for each of the plurality of control valves such that the total sum of the flow rates (calculated based on the criteria) is equal to or less than the total maximum flow rate.

Abstract: A low-cost compact ignition sense and control circuit is powered by a battery supply line of a vehicle and receives an ignition input signal indicating the turning ON/OFF of a vehicle. Responsive to the ignition input signal, the ignition sense and control circuit utilizes first and second MOSFETS to control an ON/OFF state of a main internal power supply of an ECU or to control an activate/deactivate state of a microprocessor of the ECU. When the MOSFETS are ON, voltage from the battery supply line is used to either latch the main internal power supply of the ECU to an ON state or to latch the microprocessor of the ECU into an ON state. An OFF signal at the ignition input signal releases the latch to provide a shutdown of the main internal power supply or microprocessor.
