Traction control device

摘要

An object of the invention is to provide a traction control device capable of preventing a reduction in acceleration. A traction control device of the invention includes a braking mechanism controller that controls a braking mechanism. The braking mechanism controller includes: a target brake torque calculating section that calculates a target brake torque to each of wheels based on the rotation speed of the wheel and an estimated vehicle speed; a target brake torque determining section that determines whether or not the target brake torque reaches or exceeds a per-stored threshold; a reference wheel determining section that selects a reference wheel used as a reference for controlling the braking mechanism based on the target brake torque to each of the wheels; and a target brake torque reducing section that reduces the target brake torque in accordance with a difference between the target brake torque to the reference wheel and the threshold when the target brake torque to one of the wheels reaches or exceeds the threshold.
