Abstract
An object of the invention is to provide a traction control apparatus capable of suitably controlling an error, if it occurs, between an estimation of a vehicle speed and an actual vehicle speed. A traction control apparatus according to the invention includes a vehicle speed estimator and a driving-force controller. The traction control apparatus includes a vehicle state determiner that determines whether the vehicle speed of the construction vehicle estimated by the vehicle speed estimator and the driving-force control by the driving-force controller are balanced, and a driving-force control changer that changes a driving-force control by the driving-force controller when the vehicle state determiner determines the vehicle speed and the driving-force control to be unbalanced.
