MULTIFUNCTIONAL TRANSMISSION VALVE WITH INTEGRATED LOAD BRAKE FUNCTION

A self-propelled work vehicle includes a vehicle frame and a plurality of wheels or tracks supporting the vehicle frame from a ground surface. A battery provides electrical power to an electric motor. A hydraulic pump provides hydraulic fluid to a hydraulic system. A steering valve directs hydraulic fluid from the hydraulic system to a steering actuator. A steering priority valve prioritizes supply of hydraulic fluid from the hydraulic system to the steering valve. A proportional relief valve provides a load sense signal to the load sense port of the steering priority valve which shifts the steering priority spool to build hydraulic system pressure. A controller is configured to detect whether the battery is able to be further charged and to control operation of the proportional relief valve to control a hydraulic braking function provided by the steering priority valve.
