A mining vehicle; a redundant dual-pump hydraulic system for a vehicle; methods

Abstract

A redundant dual-pump hydraulic system for a vehicle includes a first hydraulic group; a second hydraulic group; a hydraulically driven vehicle component selectively driven by the first hydraulic group and the second hydraulic group; and a system controller including a device processor and a non-transient computer-readable medium.The computer-readable medium includes instructions executable by the processor to perform the following functions: receiving data relating to a first vehicle parameter and a second vehicle parameter; and selecting which hydraulic power unit drives the hydraulically driven vehicle component based on the received data relating to the two or more vehicle parameters; wherein the received data are weighted for each of the vehicle parameters, such that one of the vehicle parameters takes precedence over the other in determining which hydraulic power unit will drive the hydraulically driven vehicle component.
