<P>PROBLEM TO BE SOLVED: To provide a traction control device capable of appropriately controlling a vehicle traction even if an error occurs from actual vehicle speed, in estimating a vehicle speed. <P>SOLUTION: The traction control device equipped with a vehicle speed estimation device and a driving force control device includes: a braking mechanism control means 84 that constitutes a driving force control device, calculates a slip ratio of each wheel from a rotational speed detected by a rotational speed detecting means, and performs the control of a braking mechanism so that the calculated slip ratio is converged to a given target value; a vehicle state determination means 815 that determines whether a balance state of driving force control by the driving force control device is appropriate or not based on a vehicle speed of a construction vehicle estimated by the vehicle speed estimation device, and a slip ratio calculated by the braking mechanism control means 84; and a driving force control changing means 816 that changes a state of driving force control by the driving force control device when it is determined that the balance state is inappropriate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
