    • 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.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.
    • 要解决的问题:为了提供一种即使在实际车速发生错误时能够适当地控制车辆牵引力的牵引力控制装置,在估计车速时也是如此。 解决方案:配备有车速估计装置和驱动力控制装置的牵引力控制装置包括:构成驱动力控制装置的制动机构控制装置84,根据检测到的转速来计算各车轮的滑移率 通过转速检测装置执行制动机构的控制,使得计算的滑移率收敛于给定的目标值; 车辆状态判定单元815,其根据由车速推定装置估计出的建筑车辆的车速,确定驱动力控制装置的驱动力控制的平衡状态是否适合, 制动机构控制装置84; 以及驱动力控制改变装置816,当确定平衡状态不适当时,改变驱动力控制装置的驱动力控制状态。 版权所有(C)2012,JPO&INPIT
