Patent ID: 8364355

Claim:
A driving force control device of a working vehicle in which a work equipment is provided, and a power of an engine is transmitted to a tire as a driving force via a driving force transmission path, the device comprising: driving force variation means for freely varying the driving force transmitted to the tire, the driving force variation means being provided in the driving force transmission path; tire slip detection means for detecting an occurrence of a tire slip; driving force measurement means for measuring the driving force; and first tire slip prevention control means for controlling the driving force variation means such that, when the tire slip detection means detects the tire slip, the driving force measurement means measures the driving force at the time of the detection of the tire slip, after the tire slip is detected, the driving force is reduced to a first driving force which is lower than the measured driving force at the time of the detection of the tire slip to suppress the tire slip, and after the tire slip is suppressed, the driving force is restored to a second driving force which is within a range that is smaller than the measured driving force at the time of the detection of the tire slip and higher than the first driving force.
