Patent ID: 8768582

Claim:
A wheel loader, comprising: an engine; a work apparatus driven by a power output of the engine; a travel apparatus driven by the power output of the engine, the wheel loader being capable of carrying out excavation work consisting of a sequence of a plurality of processes, by operating the work apparatus while traveling by the travel apparatus; a hydraulic oil pressure detector which detects a hydraulic oil pressure of one or more hydraulic cylinders which drive the work apparatus; a work apparatus operation command detector which detects an operation command to the work apparatus; a transmission operation detector which detects operation of a transmission included in the travel apparatus or detects operation of a speed stage selected in the transmission; and a controller which determines which process in the sequence of the plurality of processes is currently being performed based on a combination of all of a detected value detected by the hydraulic oil pressure detector, a detected operation command detected by the work apparatus operation command detector, a detected value detected by the transmission operation detector and a history of previous determinations of at least transmission speed stage and work apparatus cylinder pressures.
